TREATMENT PLANTS FOR CAR WASHES
SPECIFICATIONS
The yrowiny interest for environmental protection and safety is focussiny more and more not only on treatment for domestic sewage or the like but also, particularly in recent years, on treatment Systems for runoff from potentially polluted imperméable surfaces.
This includes water from car washes, which is characterised by the presence of various types of pollutants such as: suspended solids (sand and mud, gravel, grit, vegetable residues,…), détergents, oils and hydrocarbons. For this reason, the purification treatment of these effluents requires a sériés of phases that treat the pollutants in succession. Choice of the different types of treatment varies according to the final discharge. The inlet concentrations are : SS s400 mg/l ; Total Hydrocarbons s50 mg/l ; Total Surfactants s5 mg/l.
The first phase consists of a grit separator in which ail the compounds of spécifie weight different to that of water are separated by gravity: the heavier materials (sand, mud, gravel,…) settle to the bottom of the tank while the lighter materials (oil, grease, foam,…) accumulate at the surface. The outlet pipe draws from halfway down the tank to prevent the separated material from being drawn-off.
