We installed this low energy reverse osmosis system which utilizes 6 low pressure membranes at a local feed mill. The water here originally tested at 1600 dissolved solids but after being treated, tested at less than 10. It allows for many more turns of the water which results in lower dissolved solids which significantly reduces both chemical and maintenance costs. This system also reduces waste water and blow off intervals to improve overall efficiency. Plus it gives a great, spot-free rinse when washing off trucks.
