Product Description
Compared with the traditional air flotation unit, the Shallow Dissolved Air Flotation Unit changes static water intake-dynamic water discharge into dynamic water intake-static water discharge, so that suspended solids (SS) float vertically on the water surface in a relatively static environment. The purification tank only takes 2-3 minutes, and the treatment efficiency is extremely high.
Shallow Dissolved Air Flotation Unit is widely used in water supply and sewage treatment projects. 1. Applied to the water treatment of waterworks with lake water as the water source, algae reduce turbidity.
Feature
Shallow Dissolved Air Flotation Unit is a kind of air flotation system. It is successfully designed according to the "shallow bottom theory" and "zero speed" principle. It integrates coagulation, air flotation, slag discharge, sedimentation and mud scraping. High-efficiency energy-saving water purification equipment.
The dissolved air system is to dissolve a large amount of air into water to form dissolved water and enter the water to be treated. After the pressure is released, a large number of fine air bubbles are formed in the water, and the impurities in the water flocculate and adhere to each other to form a floating body with a specific gravity smaller than that of water. Therefore, the water surface rises quickly, and the solid phase and liquid phase are separated by the slag scraping device, so that the water quality is purified.
The main body is composed of pool body, skimming device, working bridge and walking device, water distribution device, water collecting device, flow collecting device and so on.
Application
Used in industrial wastewater treatment systems (such as: papermaking, food, electroplating, tanning, knitting, printing and dyeing, wool spinning, slaughtering, petroleum, chemical industry, etc.), especially for fiber recovery in papermaking industry; also used for pretreatment of water and raw water (e.g. algae removal, turbidity); also used for concentration treatment of biological sludge. The third is the recovery of useful substances in sewage, such as papermaking, pulp and fiber recovery in water.
