Treatment of wastewater contaminated with detergents

Without adjustment of the pH value of car-wash wastewater, it was found that 200 ppm of ferric chloride, as a coagulant, and 1 ppm of potassium permanganate, as an oxidant, are the optimum doses. The COD and turbidity values of the final treated wastewater were reduced by almost 88 and 100%, respectively.

In fact, the quality of drinking water in Switzerland is the same as the quality of mineral water. The water is so clean that half of water coming from the tap in Switzerland hasn’t been treated in any way, and therefore, does not have any chemical aftertaste [1].. This is because 40 percent of drinking water comes from natural springs, other 40 percent from pure groundwater and the
