Using organoclays to remove oil from water

If this does not work, the pH is adjusted downward, as low as 3.5 in the case of lubricants, with sulfuric or hydrochloric ,acid,. Then a cationic or anionic flocculant may need to be added to cause flocculation of the coagulated droplets, i.e. a rise to the surface of the tank so they can be skimmed off.

An Unconventional Approach To Dairy Wastewater Treatment

The alternative approach to treating the ice cream plant ,wastewater, involves a different chemical process — acidulation. In the acidulation process, sulfuric ,acid, is used to lower ,wastewater, pH to the level where the emulsified oils and milk proteins ,coagulate, which is between 3.9 and 4.3.

Wastewater Technology Fact Sheet: Ozone Disinfection
Wastewater Technology Fact Sheet: Ozone Disinfection

wastewater and the diseases associated with them. Ozone is produced when oxygen (O 2) molecules are dissociated by an energy source into oxygen atoms and subsequently collide with an oxygen molecule to form an unstable gas, ozone (O 3), which is used to disinfect wastewater. Most wastewater treatment plants generate ozone by imposing a high voltage
