Daf Wastewater Purification Equipment, Sewage Treatment System



YW  series Dissolved Air Floatation is mostly for solid-liquid or liquid-liquid separation.Huge sum of micro bubbles developed by dissolving and releasing program adhere to sound or liquid particles with same density as waste drinking water to make the total float to the area hence obtain the intention of strong-liquid or liquid-liquid separation.


Dissolved air system  is composed of Air Dissolving Program (dissolved air pump,air compressor,dissolved air tank,releaser and many others.)air floatation tank,scraping system(foam scraper reducer,chain,scraping board and many others).

Doing work Theory

Pollutants in wastewater can be divided into soluble natural issue and the solubility material(SS),soluble natural matter below specified conditions,can be converted into a soluble compound,one particular approach sewage remedy is to be part of coagulants and flocculants to make most of soluble natural make a difference change to the soluble substances,then remove all or most of the soluble compound(SS) removing in order to obtain the objective of the sewage remedy,and the primary approach of getting rid of SS is air flotation strategy.Following the chemical reaction,the wastewater enters the mixing zone,which is combined with the dissolved air drinking water right after releasing,so that the flocs adhere to the little bubbles and then enter the air floating zone.The flocs would type floating scum,the below clear drinking water would flow into the cleanse water tank,a portion of drinking water reflux as dissolved air h2o,the other component of drinking water overflows through overflow hole.When the scum on the water area of the air float is amassed to a specified thickness,it is discharged from the sludge tank by the scraper.


one.Separation of oily(like emulsified) wastewater from petroleum,chemical and machanical processes.
two.CZPTvery of sewage natural and organic subject.(such as recovery of pulp fibers and fillers from paper mill wastewater)
three.Treatment method of wastewater with high chroma and reduced dissolved oxygen.This kind of as textile printing and dyeing wastewater treatment.
four.Therapy of oxide-wealthy wastewater made up of algae.
5.Treatment method of minimal temperature and lower turbidity sewage.
six.Change secondary sedimentation tank,suited for the predicament that is effortless to generate sludge swellingIt is suitable for the focus of residual activated sludge and handy for the remedy of filter push
