Home DELTA Industrial Reverse Osmosis System
Three reverse osmosis Delta units installed on a concrete slab inside an industrial warehouse with each unit consisting of horizontally oriented plastic filtration pipe units stacked within a blue metal frame along with an electrical panel and pipes of various sizes with valve and gauge components

DELTA Reverse Osmosis (RO) Systems

DELTA Reverse Osmosis (RO) Systems provides effective, continuous dissolved solids recovery up to 80%+ in a modular small footprint design.  The DELTA Systems can accommodate a wide range of feed water qualities with either a single or double pass and offer you very consistent permeate quality for increased boiler blow-down and reduced scaling.
