Cosmetic wastewater demulsifier is a kind of demulsifier for daily chemical wastewater containing emulsified wastewater. The amount of water in the cosmetic wastewater is not large, but the high concentration wastewater contains high compounds, and the wastewater composition is complex, so the demulsifier added in the cosmetic wastewater can emulsify oil, surfactant, colloidal demulsification, decolorization, separation and flocculation precipitation; At the same time, it can adsorb electricity and flocculate particles in water, remove COD, chroma, total phosphorus, heavy metals in water, etc., and is an effective water treatment agent for the treatment of cosmetic wastewater.
Through the use of Bejingshi cosmetic waste water demulsification water clear effect, clearly visible, clear water quality. For many cosmetic wastewater manufacturers to solve the problem of breaking milk
Test method: Add demulsifier to cosmetic wastewater, add a dose of 0.5 to 3 ‰, and then adjust PH 7-9 with lye, see if there is a small floc in the sample cup, there is floc is the demulsification effect. Finally add PAM anion solution to help fast flocculation precipitation, which is the effect shown in the above experiment cup!
Demulsifier common problems
01 The use of demulsifier also add PAC?
A: Generally not needed, need to be used with polyacrylamide, which can speed up the precipitation clarification time.
02 How to adjust the PH of wastewater?
A: The wastewater is too acidic and needs to be adjusted with alkali, such as: sodium hydroxide (liquid/alkali), hydrated lime, complex alkali, The wastewater is too alkaline and needs to be adjusted with acids, such as hydrochloric acid, sulfuric acid,
03 Is it harmful to the strain?
A: It has no effect on the strain, and can be added before and after biochemistry.
