Water Testing Treatment Process System

Composition and operation of dosing device:

Dosing system device components: Dissolved tank, stirrer, metering pump, level gauge, electrical control cabinet, pipe, valve, distributor, safety valve, regulator, pressure gauge, check valve, rack, etc. composition.

Waste water Treatment System;

The concentration of the drug should be adjusted according to the water quality and the effluent quality.

Dissolved coagulant aid and coagulant agent should be used along with random, otherwise it will effect the treatment effect of the agent, effecting the quality of the effluent.

Dissolved uneven, agglomerated agents can not be used, by using these agents dosing pipe and flow meter will block, resulting in poor chemical.

Before starting the metering pump, open the inlet and outlet valves of the pump before and after the pump, start and close the isolation valve between the metering pumps.

In operation, such as working pump failure should be cut off the working pump power, open, close the corresponding valve, start the standby pump, continue to dosing.

Should be regularly on the level gauge for sewage, cleaning filters often visit the dissolved tank level changes, and timely replenishment solution.

In order to ensure the quality of the effluent water, under normal circumstances, the coal water treatment system starts a set of water-making equipment (1 wastewater lifting pump, 1 coagulant dosing pump,

1 coagulant dosing pump and 1 high-efficiency purifier) Another set of water equipment is available as a backup.

 Under normal circumstances, the frequency of the coagulant dosing pump is set to 20HZ, and the frequency of the coagulant dosing pump is set to 50HZ. If the actual water quality of the turbidimeter is unqualified, another coagulant can be activated. The chemical pump increases the amount of the coagulant.


After the turbidity decreases, gradually reduce the other coagulant dosing pump to 0HZ (stop the other coagulant dosing pump).

In order to improve the detection accuracy of the turbidity meter, the turbidity meter is required to send electricity before the start of the water-making work, and the power is turned off after the water-making work is finished. Which high-efficiency purifier is used to turn on or off which set of high-efficiency purifiers corresponds to turbidity. When the data displayed by the turbidimeter is found to be highly deviated from the

test data of the turbidity meter outlet sample in the laboratory, the thermal control professional of the maintenance department should be contacted in time for verification.

In order to avoid the leakage of the valve, effecting the dosage of the coal-containing wastewater and the quality of the effluent, under normal circumstances, when starting a coagulant dosing pump and a coagulant aid dosing pump, another coagulant should be added. The outlet manual valve of the pump and coagulant dosing pump is closed (Note: Open if another dosing pump is required

What Is Pressure With Explanation

What Is Pressure With Explanation : Is usually going for you guys.  In the industry, it is also associated with the highest unit and pressure: be it a small industry, be it an ice or cement factory.  Earnings or a street house.  You will have Yashar everywhere.  It is very difficult to understand the  instruments that are broadcast without  understanding the pressure.  Pressure is considered to be the basic meter in the world of instruments. What is pressure?   In common place air pressure is called pressure.  It is given even in football.  Whether in the tire tube of small scale, motorcycle, car, etc.  And also falls into the category of pressure.  Even blowing through the mouth is considered stressful.  If you have heard.  Fill this car with 40 pounds of air.  Pound here means pound per square inch.  This is a unit of pressure.  This will be mentioned in detail.  The doctor advises some patients ...

Backwash Work Of Coal Water Treatment System

Backwash start and stop operation steps: 1 Confirm that the coal water treatment water equipment has stopped working 2 Open the slime water purifier backwash inlet valve, mud valve. 3 Start backwash pump until slime water purifier drain valve starts to drain water. 4 Stop the backwash pump, close the slime water purifier backwash inlet valve, mud valve. 5 Slowly open the backwash pump when the following three conditions, the coal slurry for back washing Coal For Water Purification 1) To purify the regular coal slurry backwash time (set 360 hours to wash once); 2) Coal slurry purifier No. 3 monitoring faucet water turbidity; 3) Water flowing through the return pipe of the coal waste water purifier. 4）The water turbidity for a long time can not meet the design requirements of water quality. Note: When the sewage pipe discharges, only the clear water is discharged, and when the sludge is not discharged, the purifier should be stopped immediately, and the purifier drain valve should be ope...
