Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

Our Gongyuan GQF Type Superficial DAF is an advanced quick-speed flotation system integrated with flocculation, flotation, skimming and mud scrapping. Based on the traditional flotation theory, we also use the “shallow theory” and “principle of zero speed” successfully.

According to the water flow direction, the sedimentation clarifier can be divided into horizontal, vertical, radial, inclined flow. Our lamella clarifier, also called inclined plate clarifier/inclined tube clarifier originates from Hazen Shallow tank theory.

GPT type automatic chemical dosing system is mainly used for preparing and adding PAM agent continuously. It is an important part of sludge dewatering system.

GJY type chemical dosing system is mainly used for dissolve powdered agent like PAC, PAM, FeSO4, and make up demanded liquid agent for use.

Central drive sludge scraper mainly suits for circular radial flow sedimentation tank of sewage treatment plant. Its major function is to scrape the settling sludge to the sludge tank in order to sludge back-flow and sludge thickening and dewatering. Depending upon circumstances, we can also set up a skimming mechanism on the water surface, collecting the float scum discharged by hopper.

During the water treatment process, it will produce different kinds of moistured sludge. The sludge dewatering system is mainly used for reducing water content, moisture rate and sludge volume. This will bring convenience for next sludge treating process.

Mechanical bar screen is an advanced solid-liquid separation unit. It is mainly applied for municipal, district WWTP pre-treatment stage, municipal rainwater and sewage pumping station, waterworks and cooling water from power plant.

Rotary drum screw is a continuous and effective fine screen removing suspended solids. It is mainly applied in pre-treatment stage of sewage treatment plant or industrial screening. Under the specified screening condition, it can remove 30%-60% of suspended solids from screened sewage.
