1, centrifuges
Centrifuges are mainly used for the suspension of solid particles and liquid separation; or emulsion of two different densities, and immiscible liquids separate (for example, from the milk separated from the cream); it can also be used to exclude the liquid in the wet solids, for example, with a washing machine to dry the wet clothes; special ultra-speed tubular separators can be separated. Can separate gas mixtures of different densities; the use of different densities or sizes of solid particles in the liquid settling speed of different characteristics, some sedimentation centrifuges can also be solid particles according to the density or size of the classification.
2, sludge dewatering machine
Sludge dewatering machine is characterized by automatic control of operation, continuous production, stepless speed regulation, applicable to a variety of sludge, suitable for water supply and drainage, papermaking, foundry, leather, textile, chemical industry, food and other industries of sludge dewatering.
3, aeration machine
Aeration machine is through the diffuser impeller, the "micro-bubbles" injected directly into the untreated sewage, in the coagulant and flocculant *** with the same action, the suspended material occurs in the physical flocculation and chemical flocculation, resulting in the formation of large suspended flocs in the bubbles group of the flotation role! "Under the floating action of air bubbles, the floc floats up to the liquid surface to form scum, which is separated from the water by scraping machine; there is no need to clean up the nozzle, and no blockage will occur. This equipment is good overall, easy to install, saving operating costs and occupy the ground.
4, microfilter
Microfilter is a drum-type screen filtration device. Treated wastewater along the axial into the drum, radial radial outflow through the screen, water impurities (fine suspended solids, fibers, pulp, etc.) that is retained in the drum on the inside surface of the screen. When the impurities retained in the screen is brought to the upper part of the drum, the pressure flushing water backwash to the slag discharge tank out. When running, the drum 2/5 diameter partially exposed to the water surface, the number of revolutions for 1-4r/min, the screen filtration speed can be used 30-120m/h, the pressure of the rinse water 0.5-1.5kg/cm2, the rinse water for the production of 0.5-1.0% of the amount of water, used in the water treatment of reservoirs, the efficiency of the removal of algae up to 40-70%, in addition to the efficiency of the plankton up to 97-100%. Microfilter covers a small area, large production capacity (250-36000m3/d), easy to operate and manage, has been successfully applied to water supply and wastewater treatment.
5, air flotation machine
Air flotation machine is a kind of equipment to remove suspended solids, oil and grease and various colloidal substances in various industrial and municipal sewage. This equipment is widely used in oil refining, chemical industry, brewing, slaughtering, electroplating, printing and dyeing and other industrial wastewater and municipal sewage treatment.
