Wastewater Reuse:600T/H Reverse Osmosis + 600T/H Ultrafiltration System

Process flow:

Reaction tank → primary sedimentation tank → aeration tank → Secondary sedimentation tank → UF → RO

Reaction tank

Water treatment equipment for chemical coagulation reaction in wastewater treatment. Add flocculant and mix evenly with water, and the resulting alum will increase rapidly in the reaction tank.

Primary Sedimentation tank

The primary sedimentation tank can remove the sinkable and floating matter in the wastewater. After the initial settling of the wastewater, about 50% of the sinkable matter, grease and floating matter and 20% of the BOD can be removed. For domestic sewage and industrial sewage with high suspended matter, it is easy to use the primary settling tank pretreatment.

Aeration tank

The aeration tank is a biochemical reactor designed by people according to the characteristics of microorganisms. The activated sludge method is used for sewage treatment. The pond provides a certain sewage retention time to meet the oxygen required by aerobic microorganisms and sufficient contact between sewage and activated sludge. Mixed conditions. The aeration tank is mainly composed of three parts: tank body, aeration system and water inlet and outlet.

Secondary sedimentation tank

The function of the secondary settling tank is to separate the sludge from water, clear the mixed liquid, thicken the sludge, and return the separated sludge to the biological treatment section. The quality of its effect directly affects the quality of the effluent and the concentration of the returned sludge. Because the sedimentation and concentration effect is not good, the effluent will increase the suspended matter of activated sludge, thereby increasing the BOD mass concentration of the effluent; at the same time, the concentration of the return sludge will also decrease, thereby reducing the concentration of the mixed liquid in the aeration tank and affecting the purification effect .

UF

Ultrafiltration is a new hollow fiber filtration technology, combined with three-stage pretreatment filtration to remove impurities in tap water; ultrafiltration has a pore size of less than 0.01 microns, which can completely filter out bacteria, rust, colloids and other harmful substances in the water, and retain the original traces in the water. Elements and minerals.

RO

Reverse osmosis technology is usually used in sea water, fresh water of brackish water; softening treatment of water; wastewater treatment and purification, concentration, and separation of food, pharmaceutical and chemical industries.
