Application scope and process requirements of water treatment dosing device

- Jun 07, 2018 -

The water treatment dosing device is a new concept of chemical water treatment dosing equipment in the process of operation. It is widely used in thermal power generation, petroleum, chemical industry and other industries, furnace water treatment systems, wastewater treatment systems and raw water. The processing system, which is installed on the same base by components such as metering pump, solution tank, control system, pipelines and valves, realizes the function of solution dissolving and metering.

Advantages of using water treatment dosing device

1. Integrated combination, compact structure and small footprint when operating.

2. The measurement of the water treatment dosing device is accurate and convenient to operate.

3. To a certain extent, it can effectively choose its different metering pumps and other components.

4. According to the requirements to effectively select its different materials.

5. Select short-range, remote, manual, and automatic control systems to achieve different control requirements.

Application scope of water treatment dosing device

Thermal power generation, petrochemical cooling circulating water treatment, raw water pretreatment, wastewater neutralization treatment.

Process requirements for water treatment dosing device

The solid agent of the water treatment dosing device is added to the dissolution kit to a certain extent, and when it is to a certain extent, the industrial water is added according to the ratio to be stirred and dissolved, and the metering dosing system is added to the dosing point when it is used. Dosing control adopts manual mode, and it can also perform follow-up control and automatic dosing according to the control signal output by the upper system.

  

The water treatment dosing device will, to some extent, have a tendency to foul or corrode due to the combined effects of the hardness of the circulating water, air temperature, ambient humidity, pH, concentration multiples, hardness, alkalinity, etc., both of which affect the circulating cooling system. The safety and operating efficiency will have an adverse effect. In order to inhibit scaling or corrosion, it is necessary to manually add corrosion inhibitors or scale inhibitors to the water.

In the water treatment process of the water treatment and dosing device, the PH value of the water in the operation process often needs to be controlled within a certain range, and the artificially effective addition of acid and alkali to the water satisfies this requirement. One of the most direct and effective methods required, commonly used acid, alkali neutralizer include sulfuric acid, hydrochloric acid, ammonia, calcium hydroxide, sodium hydroxide, sodium carbonate and so on.
