We recently commissioned a 30,000 litres per day Reverse Osmosis (RO) plant for Washworx Carwash in Cobram, Victoria. The owner, Nik, wanted to reduce his reliance on, and cost of using mains water. The RO desalinates water from Washworx's on site bore. The treated water is used for washing cars with a "spot free" rinse and for the large on site laundromat. The treated water quality is superior to Cobram mains water supply having lower conductivity, dissolved and suspended solids. An added bonus for washing cars and cleaning clothes.
