What agents are used in the circulating water dosing system and what are the characteristics?

The circulating water dosing system can use scale inhibitor, bactericide, dilute sulfuric acid and other agents, which can be widely used in open cooling water system, closed chilled water system and various large-scale water-cooled central air conditioning systems. The following is a specific introduction to "what agents and characteristics are used in the circulating water dosing system".

1、 What chemicals are used in the circulating water dosing system

1. Scale inhibitor: it can chelate with calcium and magnesium ions in water, disperse ions, remove scale and prevent the formation of scale. There are many kinds, including inorganic, organic and composite, acidic and alkaline. It is necessary to select appropriate scale inhibitor according to the composition of water quality.

2. Bactericide: it can kill algae and microorganisms in water. There are oxidizing bactericides such as sodium hypochlorite, chlorine dioxide, hydrogen peroxide and non oxidizing; There are many oxidizing types commonly used in circulating water, which can be used alternately with non oxidizing ones to prevent bacteria and microorganisms from developing drug resistance.

3. Dilute sulfuric acid: adding acid to the circulating cooling water system is mainly to reduce the pH value of the water and stabilize the bicarbonate. Adding sulfuric acid to the circulating cooling water system will change the calcium carbonate hard in the water into non calcium carbonate hard with high solubility, reduce the scaling tendency and reduce the alkalinity of the water.

2、 Characteristics of circulating water dosing system

1. It is widely used in open cooling water system, closed chilled water system and all kinds of large water-cooled central air conditioning systems;

2. Realize the functions of automatic dosing and automatic blowdown of all agents such as scale inhibitor, corrosion inhibitor and bactericide;

3. Online detection items can include pH, ORP, conductivity, residual chlorine, turbidity, corrosion rate and reagent concentration;

4. It can realize wireless remote transmission of all online parameters and equipment operation status and real-time status monitoring of mobile phone;

5. Online instruments, metering pumps and pipe valves shall be selected from international well-known brands to ensure the long-term stable operation of the system;

6. Long term supporting cooperation with many domestic and foreign water treatment pharmaceutical manufacturers.
