Who is a chemical water treatment operator?

Quality of both cold and hot water, coming from the tap, must comply with the standards. The heating supply during the cold season must also be efficient. The chemical water treatment operator is supposed to monitor all this.

A representative of the profession in question is a specialist who maintains water treatment plants. In addition, the chemical water treatment operator must monitor the quality of operation of the boiler room and its elements. If even a minor mistake is made in the operation of the water treatment system, then everything can turn out in the worst possible way. That's why this profession is so important and necessary.

Responsibilities and functions of a chemical water treatment operator

Like any other specialist, a chemical water treatment operator has a number of professional responsibilities. Of course, all functions vary depending on the rank and qualifications.

However, some main types of activities can still be identified. Firstly, it is the elimination and identification of various types of problems and malfunctions in the operation of water treatment equipment. Secondly, it is the start and stop of the entire serviced system. You can also highlight such important responsibilities as maintaining the water purification process, working with filters, preparing special raw materials, selecting, regulating and maintaining a certain operating mode, etc.

A representative of the profession in question must know the following points:

• analysis methods;
• installation of various equipment;
• how to start and stop serviced units;
• properties of certain solutions and some other things.

Thus, the chemical water treatment operator has rather difficult responsibilities. However, training in this profession will help you fully get comfortable and acquire necessary knowledge. And you can get all the knowledge about the profession in vocational schools, training centers (courses), as well as in courses specially created by enterprises with permission (license) from technical supervision authorities. Training programs must be coordinated with the technical supervision authority. Individual training of personnel is not permitted.

What qualities should a chemical water treatment operator have?

Of course, not every person will be able to get a profession in the field of thermal power engineering. And all because to work you need to have certain qualities and skills.

What can be said about the qualities that a worker must have, about the character traits necessary to obtain a profession?

A chemical water treatment operator must have incredible, almost exorbitant accuracy. The duties of this worker require special care.

• cleaning and washing of some types of equipment and more.

It is worth noting that a first-class chemical water treatment operator performs many of his functions only under close attention a specialist with a higher rank. It is also worth noting that not all of them were mentioned above, but only the most basic functions. The worker's responsibilities may vary depending on the station, region, etc.

About the second category in the profession

A chemical water treatment operator with a second category is endowed with slightly great features and credentials than a specialist with an initial rank. Thus, his powers include the following job responsibilities:

• water purification using various chemical processes (liming, chlorination, desalting, etc.);
• maintenance of water treatment equipment with a capacity of no more than 70 m 3 /h;
• monitoring the readings of various measuring instruments;
• cleaning and washing of equipment;
• repair of some equipment;
• filling out a log about the operation of installations.

A second-class specialist may also have some other functions. But it depends on the workplace.

About the third category in the profession

What does the job description prescribe about the third category of the profession in question?

A chemical water treatment operator of this qualification has the following functions and responsibilities:

• chemical water purification in installations with a capacity of 70 to 300 m 3 /h;
• regeneration of some filters;
• work with raw materials: preparing substances for crushing, sifting, clarification, heating, etc.;
• work using special filters (under the guidance of a fourth-class chemical water treatment operator);
• manual or automatic control of water supply to technological stations.

In addition to all of the above, a third-class specialist is required to start and stop equipment, adjust temperature regime, identify and troubleshoot problems, etc.

About the fourth category in the profession

A specialist of the last, and therefore the most important, category has a number of very extensive powers.

Among them are:

• on equipment with a capacity of at least 300 m 3 /h;
• conducting a deep process of water desalination on all available filters;
• the process of measuring the electrical conductivity of demineralized water;
• full control over the operating mode (namely temperature, pressure, water supply speed and much more) in accordance with established standards;
• removing unnecessary impurities from water;
• ensuring optimal operation of all equipment - monitoring the cleaning, flushing and lubrication of units;
• delivery of equipment for repair and its acceptance from repair;
• recording all necessary indicators and data in the production log.

Since a fourth-grade chemical water treatment operator is a very responsible and important position, there may be much more functions here.

On the responsibilities and rights of a chemical water treatment operator

Labor protection for a chemical water treatment operator includes certain types rights and responsibilities.

What is the responsibility of a representative of the profession in question? The job description prescribes the following points:

• maintaining a work log;

17. Instructions for chemical water treatment

Description of the chemical scheme water treatment

17.1. Chem. water treatment works according to a two-stage sodium cationization scheme.

17.2. As raw water for chemical The water treatment system receives artesian water, either directly from the cold pressure tower or through a heater. When using a heater, water should be supplied to the cold water treatment plant with a temperature of no higher than 40-50 degrees, in order to avoid damage to the sulfonated coal loaded into the cathine filters.

17.3. After filters, 2 stages of chemical. water treatment, purified water enters the deaerator, where it is mixed with the condenser and forms feed water for boilers, as well as for feeding the heating network. The working salt solution is prepared in a wet salt storage bin.

18. Instructions for maintenance and operation of sodium cathine filters.

18.1. When water is filtered through sodium cathine filters, scale-forming cations (calcium, magnesium) are exchanged for sodium cation. This process can be represented as follows:

2NaR + Ca(HCO3) = CaR + 2NaHCO3

2NaR + Mg(HCO3) = MgR + 2NaHCO3,

where R is a complex cation complex. By releasing sodium into the water and retaining calcium and magnesium cations, the cation exchanger is gradually filled with these cations and loses its ability to soften water. During regeneration, the depleted cation exchanger is treated with a salt solution, passing through the layer of depleted cation exchanger, sodium ions displace calcium and magnesium cations from it, which go into the solution. The cation exchanger enriched with sodium cations regains the ability to soften water. The reaction that occurs during regeneration can be represented by the following equation:

CaR + 2NaCl = 2NaR + CaCl

After regeneration, washing is performed to remove excess regenerated solution and regeneration products.

19. Sodium cathine filter device.

19.1. The sodium cathine filter is a cylindrical oval body with spherical bottoms. Support feet are welded to the bottom bottom for installing the filter on the foundation. Inside the filter, in its upper part, there is a device in the form of an intermediate bottom for supplying raw water and a regeneration salt solution and removing loosening water. This device serves to uniformly supply and distribute the regeneration solution of salt and water over the entire cross-section of the cation filter. The filter has one lower hatch and an upper cover, made to allow installation and repair of internal devices, as well as periodic inspection during operation. At the bottom of the filter there is a drainage device, which is an intermediate bottom with fittings and caps that serve for uniform distribution of loosening and drainage of chemically treated water over the entire cross-sectional area.

19.2. The filters are loaded with sulfonated carbon, the loading height is 2 m, the grain size is 0.5-1.25 mm. The filter is equipped with pipelines used for supplying raw water, discharging softened water, and supplying solution table salt, supply of washing water for loosening and drainage of water into the drainage. There are two sampling points for taking water samples before and after the filter. There are two pressure gauges installed on the filter (one at the inlet, the other at the outlet of the filter).

20. Maintenance of sodium cathine filters.

The operation of sodium cathine filters consists of periodically performing operations that make up a full operating cycle:

1. Loosening 2. Regeneration

3. Washing 4. Softening

20.1. Loosening.

Loosening is carried out before regeneration, due to which the contaminants accumulated in it and small particles of sulfur coal formed as a result of its partial grinding during operation are removed from the cation and the possibility of better processing of the cation exchanger with a solution of table salt is created.

Loosening of the cation exchanger is carried out by the reverse flow of water from the pipeline through the lower drainage system and discharge from it through a distribution device located in the upper part of the filter.

Loosening is done as follows:

close the control valve between the loosening valves;

open the valve connecting the upper part of the filter with the discharge into the drain;

open one by one both loosening valves feeding raw water V bottom part filter, adjust the intensity of loosening with one of them (there should be no large particles of sulfur coal in the discharged water).

The loosening intensity should be approximately 11-14 m3/hour, the total loosening duration is 20-30 minutes at a speed of 5.5-6 cubic meters/hour or 90-100 l/min. With a total loosening time of 20-30 minutes, loosening will take 2-4 cubic meters. water. When loosening is carried out, samples of drain water are taken every 2-3 minutes, in which the content of fines is determined by eye. When removing large particles, the intensity of loosening should be reduced by closing the valve. As soon as the wash water sample becomes clear, the loosening operation is stopped. At the end of loosening, the valves are closed and the pump is turned off.

20.2. Regeneration.

Regeneration of sodium cation filters produced with a 6-9% solution of table salt. To turn on the filter for regeneration, it is necessary to open the salt release valve to the filter and the filter lower drain valve. Turn on the salt pump and adjust the flow rate of salt using the valves. Check for air in the upper part of the filter by opening the vent valve until water appears. Pass the required amount of solution through the level in the wet storage bin.

20.3. Washing.

Once the salt has passed through the filter and all salt valves have been closed, the filter is placed for cleaning. Washing is done with the aim of releasing the spent regeneration solution into the drainage and is carried out at a speed of 4-5 cubic meters per hour, which corresponds to 2.0-1.5 cubic meters per hour. Washing with quantities of water less than specified leads to an increase in water for the chemical treatment plant’s own needs and does not provide positive result washing. The washing is done for 20-30 minutes, then take a taste test (you can taste the water earlier, at the beginning it will be bitter, then salty at the end of the washing). If the water is fresh, then it is checked for hardness.

If the 1st stage filter is put into operation after regeneration, it must be washed to 300 mcg-eq/l; the 2nd stage filter is washed to 50 mcg-eq/l.

If the filter is not placed in reserve after regeneration, then in order to avoid peptization of the cation exchanger, it is partially washed from the regeneration solution, i.e. to a hardness of 400-500 mcg-equiv/l. The final cleaning is done before putting the filter into operation.

20.4. Softening.

To turn on the cation exchanger filter for the “softening” operation, you must:

make sure that there is no air cushion in the filter (this is done before adding salt and before washing), there is an air vent on the filter, it opens until water appears, then closes.

The valves at the inlet to the outlet filters open. The softening speed should be 20 m/h.

Chem. Work control is carried out according to the schedule. By the end of the filter operation, the chemical control becomes more frequent. While the filter is operating, the vent opens to release air accumulated in the filter.

The filter is switched off by closing the valves at the filter inlet and outlet.

When softening water, you need to check the water for removal of sulfonic carbon. If sulfonated carbon appears, this indicates a failure drainage system, the filter emergency stops, sulfonated carbon is expelled from it and the drainage system is inspected and repaired.

20.5. Chemical water control.

Chemical control of water used for the needs of the boiler house is carried out through timely sampling of water and its chemical analysis. Water samples are taken from certain designated points in the boiler room thermal circuit through sampling valves. To avoid errors, before taking samples from samplers installed at some distance from the sampling point, it is necessary to flush the line into the drain with a sufficient amount of water, after which the water is drawn into a container that has been previously washed with the water being sampled. The glassware must be labeled for each sample and used strictly for its intended purpose.

The sampler valve must be constantly open so that the water in the sampler does not stagnate.

Frequency of sampling.

Raw water: alkalinity – once a month

hardness – once a month.

Full analysis - once a year (in a specialized laboratory).

Chem. purified water: hardness – each time the filter is put into operation, in case permanent job filter, analysis should be carried out after an hour, until the water is soft, and after 10-15 minutes before stopping the filter for regeneration.

21. Instructions for water analysis.

Determination of hardness using the trilonometric method:

Required details:

0.01 – solution of Trilon “B”

ammonia buffer solution

indicator solutions: dark blue chrome.

Determination technique.

100 ml. The test water is added to a conical flask with a capacity of 250 ml., 2-5 ml are added. ammonia-buffer solution, 7-8 drops of dark blue chromium indicator and slowly titrated with a 0.01 N solution of Trilon “B” until the pink turns blue; when determining hard water, titrate with a 0.1 N solution of Trilon “B” in ml. multiplied by 100. Example: titration of 100 ml. 0.4 ml of water was used. Trilon "B" 0.01N.

Water hardness = 0.4x100=40 mcg-eq/l.

Example: when titrating with a 0.1 N solution of Trilon “B”, the hardness is in mg-eq/l. is equal to the amount of Trilon “B” consumed in ml. If for tetration 100 ml. 4 ml of water were used. A 0.1 N solution of Trilon “B” will result in water hardness of 4 mEq/l.

Note: 1 mEq/L = 1000 mcg-Eq/L.

If there is zinc in the water, 1 ml should be added to the water sample before determining the hardness. 1.5-2% solution of sodium sulfide, in the presence of manganese, add 5 drops of 1% solution of hydroxylamine hydrochloride before introducing the reagents.

Preparation of reagents.

0.1N solution of Trilon “B” 18.620 g. Dissolve in a liter volumetric flask; if the solution turns out to be cloudy, it should be filtered and then the volume of the solution should be brought to 1 liter with distilled water. The titer is set with a 0.1 N solution. For this, take 10 ml. The 0.1 N solution is brought to 100 ml with distilled water, 2-5 ml are added. ammonia-buffer solution, 5-7 drops of dark blue chromium and slowly titrate with stirring a 0.1 N solution of Trilon “B” until a clear change in the color of the solution.

Ammonia buffer solution.

20 ammonium chloride is dissolved in distilled water, add 180 ml. 25% ammonia solution and bring to 1 liter with distilled water.

Indicator solutions.

Acid chrome dark blue 0.5 g. dissolve in 10 ml. ammonia buffer solution and bring to 100 ml. ethyl alcohol.

Determination of alkalinity.

The alkalinity of natural waters, both surface and deep, is determined by the presence of bicarbonates and humates in them, i.e. salts, weak organic acids. The alkalinity of water softened only by cationization is also due to bicarbonates and humates.

The alkalinity of boiler waters is due to the presence of caustic alkalis, soda phosphates, silicates and humates. Below is a table showing the substances that cause alkalinity in various waters.

Natural water humates

Cationized NaHCO3, humates

Nutrient NaHCO3, Na2CO3, NaOH

Lime-cationized sometimes humates

Boiler NaOH, Na2PO4, Na2CO3, Na2O3, humates

Steam condensate NaHCO3, salts of organic and volatile acids

When determining the alkalinity of boiler, softened and natural waters, titration is carried out with a 0.1 N acid solution in the presence of the indicators phenolphthalein and methyl orange.

Necessary reactors.

Solutions of hydrochloric or sulfuric acid, 0.1N and 0.01N concentrations.

A solution of NaCH 0.1H concentration, H2, O4 or HC.

Indicators: 1% alcohol solution of phenolphthalein, 0.1% aqueous solution methyl orange, mixed indicator.

Method of determination.

To determine the alkalinity of boiler boiler, softened, natural water pipette 100 ml. into a conical flask with a capacity of 250-300 ml, add 2-3 drops of an alcohol solution of phenolphthalein and, when a red color appears, titrate with a 0.1 N acid solution until discoloration. Record the result. Add 1-2 drops of methyl orange and continue titration until the color changes from yellow to orange. Record the acid consumption used for titration using methyl orange.

When determining the alkalinity of river, artesian and softened water using indicators phenolphthalein and methyl orange, the following cases may occur:

1. Water is not colored by phenolphthalein. Acid consumption for methyl orange is greater than zero.

2. Acid consumption for phenolphthalein is greater than for methyl orange.

Calculation for determining hydrate, carbonate, bicarbonate and total alkalinity is carried out according to the table below:

Consumption of 0.1N acid, ml. Present in water

FF 0 bicarbonates

F1F 0 humates

FF MO carbonates

F1F1 0 bicarbonates, humates

FF OM hydrates

F1F1 0 Carbonates, humates

where: FF – acid consumption for phenolphthalein in ml.

MO – acid consumption for methyl orange in ml.

Ф1Ф1 – acid consumption for back titration

and v/a is greater than v/

and in/ a is less than in/.

Alkalinity of water in MKG-eq/l. during titration and ml. water with an acid solution is equal to the acid consumption multiplied by (in mcg-eq/l.).

Alkalinity of water in µg-equiv/l. when titrating ml. water N acid solution is equal to the acid consumption.

Preparation of reagents for determining the alkalinity of an acid solution.

An acid solution is prepared using concentrated hydrochloric or sulfuric acids. The concentrations of strong acids are checked using hydrometer. Quantity ml. concentrated sulfuric acid required to prepare one liter of 0.1N acid is determined by the following proportion:

X – 4.9 X = 1000 x 4.9

Where: A is the concentration of the initial sulfuric acid in grams/cm. cubic, which is in the table by specific gravity.

4, 9 – the number of grams of sulfuric acid contained in one liter of 0.1N solution.

Suppose you need to prepare 20 liters. 0.1N sulfuric acid, then you need to take (1000 x 4.9 x 20) ml. concentrated acid and add 20 – (1000 x 4.9 x 20) A liters of water to the bottle.

Indicators.

1 gr. phenolphthalein is dissolved in 100 ml. ethyl alcohol (phenolphthalein 1%).

Methyl orange.

0.1 gr. methyl orange is dissolved in 100 ml. hot water, filter if necessary.
