8	Mineral oil	mg/l	5
9	Coliform	MPN/100ml	3.000

► Wastewater treatment process

- Wastewater from paint spray chambers is periodically discharged to the collection tank

- Wastewater is pumped to the coagulation-sedimentation equipment

- After a certain settling time, the water in the clarifier separates into two separate parts

- Continue the water flow pumped by high pressure to the absorber

- The adsorption of toxic substances, organic compounds, colors and odors of the remaining suspended substances, that the previous treatment processes have not done yet, ensure the quality of the treated water.

- The solid sludge will be collected and packed into bags, periodically processed together with the companys hazardous waste.
