1 CMH Reverse Osmosis Water Treatment System for Car Wash, Vehicle Detailing and Water Reuse

Skid-mounted RO + pretreatment plant for dealership vehicle washing, spot-free rinsing and water reuse.

Product Overview

The FG-RO-1000L is a factory-assembled, skid-mounted reverse osmosis plant engineered for car dealerships, automated wash tunnels, detailing bays and vehicle-wash operators that need a dependable supply of low-TDS, spot-free process water. Rated at 1.0 CMH (1,000 L/h) of permeate, it converts tap, borehole or municipal feedwater into high-purity water that removes the hardness, salts and dissolved solids responsible for water spots, streaking and paint-finish defects on vehicles.

Built around a stainless-steel 304 skid, multi-stage pretreatment, DOW/Vontron RO elements and PLC-based control, the system protects high-pressure pumps and wash equipment, cuts detergent consumption and supports reclaimed-water duty where discharge limits apply. Every unit is supplied as a plug-and-run train: raw-water pumping, media filtration, softening, precision filtration, high-pressure pumping and membrane separation are pre-piped, pre-wired and tested before shipment.

Technical Highlights

•  Permeate capacity 1.0 CMH (1,000 L/h); scalable across the FG-RO series from 0.125 to 20 CMH.

•  98–99% salt rejection and up to ~100% removal of bacteria, colloids, organics and heavy-metal ions.

•  60% standard recovery; anti-scaling dosing and softening protect the membrane train on hard feedwater.

•  Operating pressure 1.0–1.4 MPa; high-pressure pump options from CNP and Grundfos for stable duty.

•  PLC control with automatic membrane flushing and online conductivity monitoring of product water.

•  SS304 frame and membrane housings; FRP pressure vessels standard, SS316L optional for aggressive water.

•  Multi-voltage readiness: 110 V / 220 V / 380 V; installed power 3–10 kW depending on configuration.

•  CE and ISO 9001 certified; machinery test report and video outgoing-inspection provided.

What Is Reverse Osmosis (RO)?

Reverse osmosis is a membrane separation process that uses a semi-permeable spiral-wound element to separate and remove dissolved solids, organic matter, colloids and micro-organisms from water. Pressurised feedwater is forced across the membrane; water molecules pass through the microscopic pores and are collected as permeate, while concentrated impurities are rejected to the brine stream. RO typically removes more than 95% of dissolved solids, over 99% of organics and colloids, and virtually all bacteria — producing the low-mineral water that prevents spotting on washed vehicles.

Process Flow

Raw water tank → Raw water pump → Quartz-sand filter → Activated-carbon filter → Anti-scaling dosing → PP precision filter (5 µm) → High-pressure pump → RO membrane train → Pure-water tank.

System Configuration & Component Breakdown

Each FG-RO-1000L train is specified from the feedwater chemistry up. The standard build includes the following components.

Key Attributes

Selling units: single item (1 set). Customisation available on packaging, core components and logo/pattern, including drawing-based, sample-based and full customisation.

FG-RO Series — Model Selection

The FG-RO family spans 0.125 CMH to 20 CMH. Select the model from the required permeate flow, feedwater TDS and target recovery. The 1 CMH vehicle-wash duty maps to the FG-RO-1000L; the double-pass (LDP) variants deliver higher-purity permeate for spot-critical finishing.

LDP = double-pass (two-stage) configuration for higher-purity permeate. 1 CMH = 1,000 L/h = 1 m³/h.

Applications & Suitability Boundaries

Primary duty: dealership vehicle washing, automated and self-service car-wash tunnels, detailing and paint-protection bays, and wash-water reuse where low mineral content and discharge control matter.

The FG-RO platform also serves:

•  Food & beverage process, ingredient and CIP water

•  Electronics and precision-rinse water

•  Boiler feed / make-up water

•  Hotels, resorts and commercial facilities

•  Agriculture & irrigation, cosmetics production, textile processing

Design boundaries: standard FG-RO trains target brackish and municipal feedwater. For seawater duty or high-TDS brackish sources (>8,000 ppm), specify the FG SWRO/BWRO range. UF should be added upstream where turbidity or silt load is high.

Frequently Asked Questions

What capacity is the FG-RO-1000L rated at?

1.0 CMH (1,000 L/h) of permeate at 60% recovery — roughly 14–16 operating hours to produce 15–16 m³ of treated water, matched to a busy dealership or mid-size wash line.

Will RO water really stop spots on vehicles?

Yes. Water spots are mineral deposits left when hard water dries on paint. RO removes the dissolved hardness and salts that cause them, giving a spot-free final rinse and reducing rework and drying-agent use.

Can the system run on reclaimed wash water?

The RO train produces low-TDS permeate suitable for reuse in wash cycles. For closed-loop reuse, add pre-filtration (media/UF) and oil-and-grease removal upstream of the RO skid; FG Water engineers the pretreatment to your reuse balance.

What feedwater can it handle?

Tap, borehole, well and municipal sources within brackish range. For high-TDS or seawater sources, the FG BWRO/SWRO ranges are specified instead. A feedwater analysis lets us confirm recovery, dosing and membrane selection.

What are the power, voltage and footprint?

Installed power 3–10 kW depending on configuration; voltage 110 V / 220 V / 380 V. The 1000L unit weighs about 500 kg as a single skid, ready for plug-and-run connection to feed and product tanks.

What certification, warranty and support are included?

CE and ISO 9001, one-year warranty, machinery test report and video outgoing-inspection. After-sales support is by video technical support and online assistance, with spare RO elements, pumps and cartridges available as consumables.
