Waste water treatment system

Waste water treatment system is the industrial equipment used for the waste water treatment, filtering system. cleaning the waste water. Many of our client' s PET washing line and the PE/ PP film washing line is use this water treatement to save water use
Working introduction:
Wastewater from the production workshop is regularly discharged into the wastewater tank. The wastewater tank
is equipment with aeration tube to provide compressed air ( the air compressed machine is offered by buyer self)
which makes the wastewater to be evenly. And the wastewater tank is also equipped with liquid level meter which
is used to control the wastewater pump, when the liquid level is low, the pump stop and when the level is high, the
pump start to deliver the wastewater to the reaction tank. First H2SO4 is added into the reaction tank to make the
PH of the water to be 7.5-8.5. And then coagulant PAC is added into the reaction tank, by the mixing of the mixer, the
impurities can be strongly absorbed and form to be agglomerate granules. These kinds of agglomerate granules
absorbs again other impurities in the wastewater, so going on, the agglomerate granules become bigger and
bigger. In order to further enhance the effect of agglomerate, little mount aid flocculant PAM should be added into
the reaction tank so that the agglomerate will become much larger, and then the impurities are separated from the
water. The following is the solid impurities and the water is together discharged into the inclined sinking tank. In
the inclined sinking tank, the solid impurities mainly sludge is discharged into the sludge box regularly time and
the comparative clean water flows into the middle water box. The middle water tank is also equipped with liquid
level meter, when the water level is low, the pump stops and the water level is high the pump start to delivers the
water to the sand filter tower so go on to the activated absorption tower and then get clean water to discharge or
reuse. However if the water level is clean enough to achieve the environment standard to discharge or reuse after
the middle water tank, it is no need the process of both sand filter tower and activated carbon absorption tower.
For the sludge after the sludge box, it is delivered to the pressing filter machine to remove the water in it to get the
comparative dry sludge and the water is delivered to the wastewater to recycle again.
