How To Treat Paint Waste

The treatment system consists of physico-chemical treatment units followed by biological treatment units. In all cases the goal is to optimize quality of water for discharge or reuse and convert the paint material into a sludge that can be dehydrated or dewatered - ideally to a range of 35 - 50 by weight waste solids - and disposed of cleanly.

Considering the practice of waste-water treatment followed in the country and the performance efficiency of each operation the best alternative is evolved.

How to treat paint waste. Tertiary treatment included post micron filtration to remove any remaining coagulated colorparticulates in the water and carbon filtration to polishremove any remaining organics. The solid blocks with remaining moisture of less than 60 drastically reduce the amount of hazardous waste and thus the disposal costs. Waste-Water Treatment Methods for Paint Industry.

A wide variety of paint and coating manufacturers and industries performing paint and coating operations are regulated by effluent guidelines that cover wastewater discharge. But obviously if you tried that with a few hundred gallons of leftover latex the local feline population might have to go without as it were. Waste paint must be safely handled packaged stored transported treated andor disposed in accordance with this guideline and all applicable Acts and regulations.

The treatment of wastewater released by the paint industry includes steps such as filtration sedimentation decantation flotation and osmosis separation.

Paint wastewater containing titanium dioxide for example can be chemically treated to cause the stream to precipitate out and form a hydroxide. For every gallon of water use 12 T Aluminum Sulfate and 34 T Lime. Wastewater treatment of paint sludge requires pH adjustment while a de-tackifying chemical is added.

Coagulation flocculation of inert organic compounds by iron chloride aided with chimec 5161 has been used to improve the wastewater biological treatability. Industrial Paint Wastewater Equipment SolutionsThe ALAR Auto-Vac Rotary Drum Vacuum Filter is treating latex paint washwaterThe Auto-Vac wastewater treat.
