ECONOMY SERIES

Reverse Osmosis Systems
2,000 to 10,000 gallons per day

Providing quality, demineralized water at a fraction of the operating costs of deionizers. ROs reduce dissolved solids, bacteria, pyrogens, and organics. All systems are heavy-duty, preassembled, and tested before delivery.

Reverse Osmosis systems are designed and manufactured for dependable service. All pumps are 316 stainless steel for durability and have a diffuser-type design for a smooth pulse free and quiet operation. The electronic control panel is protected by a NEMA 4 enclosure and operates on 120 vac. Many standard features are included to provide the greatest efficiency from a Dayton Water Systems RO unit. RO units can be custom-designed if the standard product line does not meet your required flow rate or other requirements.
