5000LPH Brackish Water Desalination RO Plant – Industrial Reverse Osmosis Water Purifier System
FG Water 5000LPH industrial brackish water RO plant for well water & underground salty water (TDS ≤8,000 ppm). PLC touch screen, 97–99% desalination, anti-scaling dosing & CIP. Factory-direct customizable configuration.
System Overview
The FG-BWRO-5000 is a fully skid-mounted, automatic 5 m³/h (5,000 LPH) brackish water reverse osmosis system engineered for continuous treatment of brackish well water and underground salty water. Built on a 304 stainless steel frame with FRP pressure vessels and UPVC piping, the system integrates multi-stage pretreatment, precision filtration, antiscalant dosing, and high-pressure RO separation into one compact industrial platform. A PLC touch screen control system delivers automatic operation, sensor monitoring, and backwash functions, while an independent CIP cleaning loop supports periodic membrane chemical cleaning. With a feed water TDS tolerance of up to 8,000 ppm and a desalination rate of 97–99%, the FG-BWRO-5000 produces low-TDS permeate suitable for industrial process water, community supply, agricultural irrigation, and small-scale drinking water applications. Customized configuration is available to match site-specific water quality and recovery requirements.

Treatment Process
Raw water pump → Automatic sand filter → Activated carbon filter → Softener → Precision filter → High-pressure pump → RO membrane system → Product water.
The pretreatment train (multi-media filter, activated carbon filter, and optional softener) removes sediment, chlorine, odor, and hardness before the precision filter traps fine particles ahead of the high-pressure pump. The antiscalant dosing system injects scale inhibitor upstream of the RO membranes to control CaCO₃, CaSO₄, and silica precipitation, extending membrane service life. The independent CIP circuit enables chemical cleaning without dismantling the membrane array.
