Chemical Dosing System

Chemical dosing systems are used to automatically inject chemicals into chemical feed tanks for water wastewater treatment.

polymer preparation system

Polymer Preparation System

Polymer preparation system is a compact automated metering unit for liquid or powder polymer preparation and dosing.

The dosing system is mainly composed of solution box, stirring box (with stirrer), metering pump, liquid level meter, flow meter, electric control cabinet, pipeline, valve, safety valve, check valve, pressure gauge, filter, base, escalator, etc. (can be configured according to the actual requirements of users). The dosing system is prepared in the stirring box according to the required concentration of pharmaceuticals, and the prepared solution is put into the solution box after being stirred evenly by the stirrer and delivered to the dosing point or the designated system by the metering pump (dosing pump).

FAQ

In the process of water supply and drainage treatment, various kinds of chemical agents are often added as scale inhibition, sterilization and algae elimination, coagulation and flocculation to achieve the purpose of water purification. These agents have solid particles and liquids, which must be dissolved, diluted and quantified in accordance with the ratio in the process of adding can achieve better results, so it is necessary to use the dosing device to accurately add and measure the water quality treatment agents.

Different water quality requires different doses, and the dosage of various drugs should be determined by small sample tests according to the composition and concentration of influent water.

In the thermodynamic system, chemical solutions such as ammonia, diamine and phosphate are automatically added into the system by the dosing system through the change of water vapor quality, so that the water vapor quality of the system is in good condition and the normal operation of the unit is guaranteed.

In the sewage treatment system, it is generally necessary to concentrate, condense, disinfect the sewage sludge, and so on. It is necessary to add coagulant, coagulant aid, flocculant, bleaching powder and other agents, but also to treat the bacteria in the sewage, and it is necessary to add disinfectant. The purpose of automatic feeding can be achieved with the dosing device to ensure that the water quality can reach the standard of discharge.

The dosing tank is mainly used for stirring, dissolving and storing all kinds of medicine in the water treatment engineering, and then adding the liquid medicine to each injection point through the metering pump or water injector.

Automatic dosing system is a mechanical device that controls the operation of dosing pump by PH meter and ORP meter, and accurately adds acid and base, oxidant, reducing agent and flocculant. The advantages of automatic dosing system are as follows: eliminating the influence of human factors on wastewater treatment effect, stable and reliable operation, greatly improving the degree of automation, and reducing the labor intensity of staff.

Dosing unit in industry is the addition of a specified dose of a drug to a specified process. At present, a large number of dosing machines and dosing control systems are available, which are widely used in sewage treatment, metallurgy, chemical industry, light industry and other industries.
