Water used in vehicle washing systems is recovered through gravity in a decanting chamber in which sand and big sized solids in suspension are kept.
By means of gravity it is conducted to a second recipient, acting as a lung, sending the water to the recycling system. The pumping is done through a pump specially designed for sludge, sheathed to avoid the transfer of particles having a size above 3 mm.
FREYLIT recycling systems receive the water and carry out the bacteriological treatment pointed out returning the water to the recycling deposit.
Recycled water is used in vehicle washing either in the pre-washing as in the washing stage, while tap water is preferred for final cleaning and waxing.
