Product List

  • Horizontal DAF

    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.

  • Screw press

    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.

  • Lamella clarifier

    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

    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.

  • Superifical DAF

    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. 

  • mechanical bar screen

    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.

  • Cavitation air flotation

    CAF (Cavitation air flotation), is a patented solid-liquid separation technology especially used for removing oil and grease, jelly and SS. By using of aerator, CAF’s special designed impeller can distribute the micro bubbles into the sewage evenly without any complicated air dissolving process. Then this will not have any blocking phenomena.

  • Multiphase mixture DAF

    Our multiphase mixture DAF, also called air-liquid mixing pump DAF, uses the multiphase pump (such as Japanese Nikuni, Germany Edur pump) to produce micro bubbles, without requiring of air compressor and dissolved air tank. Due to its special hydraulic parts design, the pump can fully mix up with the liquid in a highly dispersed state, like a dynamic mixer.

  • Sedimentation DAF

    Sedimentation DAF has proven to be very effective for the removal of biological solids from wastewater streams

  • Vertical DAF

    GSLF vertical DAF has the same working principle with other DAF. But for the structure, we have made some adjustment. GSLF type vertical DAF has cylindrical tank, using central water distribution and peripheral outflow.

  • Double-effect DAF

    Dissolved air flotation is the most efficiency measure of solid-liquid separation which is used to separating suspended solids whose density is less than or equal to 1 in water supply and drainage treatment process.

  • Experimental DAF

    In the water supply and drainage treatment process, solid-liquid separation technology and equipment is one of the key projects. Air flotation is one of the most effective methods for the removal of tiny suspended particles with a specific gravity close to that of water.
