The automatic dosing device is an automatic dosing equipment, which can be divided into integrated automatic dosing device, circulating water automatic dosing device, boiler automatic dosing device, phosphate automatic dosing device, etc. The specifications of each dosing device are not the same. This should be noted in the selection, different industry needs should choose the corresponding equipment. The dosing device is a complete set of equipment with dosing, stirring, conveying liquid and automatic control. It is used for the circulating water system that needs to add buffer, scale inhibitor and bactericide to accurately add and measure the water quality treatment agent. In the process of water supply and drainage treatment, various chemicals are often added as scale inhibition, sterilization and algae control, coagulation and flocculation to achieve the purpose of water purification.

The dry powder dosing device is composed of five systems: automatic feeding system, automatic water supply system, automatic mixing system, automatic dosing system and its control system. All system equipment are installed on the same base platform to realize the whole process of integrated automatic control.

Catering type oil-water separator is mainly used to separate and collect solid dirt and grease in catering wastewater, and the treated wastewater is discharged into the city sewer pipe.

Industrial oil-water separator consists of floating floating oil collector, gas-liquid mixing pump, oil-water separator, waste oil tank, control system, etc. The oil-water separator adopts aggregation method, air flotation method, gravity method and other methods to effectively separate oil-water. Aggregation method: inside the equipment, oily liquid uninterrupted synchronous flow through the equipment special coalescence device of the moment, small oil droplets coalesce into larger oil droplets, from small to large, accelerate the rise, increase the separation speed. Air floatation: through the air into the equipment, so that the air in the form of air bubbles as a carrier to the water of fine oil droplets and suspended particles on the water surface.

The integrated sewage treatment equipment is a device that integrates the primary sedimentation tank, the I and II contact oxidation tanks, the secondary sedimentation tank and the sludge tank, and carries out blast aeration in the I and II contact oxidation tanks, so that the contact oxidation method and the activated sludge method are effectively combined, thus saving the equipment for designing sewage treatment process and infrastructure construction.
