500 LPH Factory RO Plant — Reverse Osmosis Water Purification System

Product Overview

The 500 LPH Factory RO Plant is a complete reverse osmosis water purification system engineered by Yufeng Water Treatment for industrial and commercial applications. It removes dissolved salts, hardness, microorganisms, suspended solids, color, odor, and impurities from raw water — delivering consistently pure water for production, processing, and direct-drinking use.

Built around a multi-stage pre-treatment train (quartz sand filter → activated carbon filter → water softener → precision filter) and a high-rejection RO membrane system, the plant achieves up to 99.8% salt rejection and produces permeate quality that exceeds standard drinking-water standards. It is the reliable, turnkey solution for factories that need stable, low-TDS process water day in and day out.

• Model: YF-RO-0.5T

• Capacity: 500 L/H (at 25°C)

• Power Consumption: 3 kW

• Working Voltage: 380V / 50Hz (customizable to your local supply)

Key Features

• Turnkey 7-stage process — from raw-water boosting to RO permeate, fully integrated and ready to run.

• Up to 99.8% salt rejection — high-rejection RO membranes filter bacteria, viruses, ions, and dissolved solids; permeate quality far exceeds daily drinking-water standards.

• Fully automatic operation — RO membranes auto-wash (plus manual wash option); auto-stop at high pure-water level, auto-start at low level. Minimizes operator attention.

• Comprehensive safety protections — power-off, under-voltage, over-current, short-circuit, and leakage protection keep the system and your staff safe.

• Anti-dry-run multistage pump — prevents membrane damage from water shortage.

• Corrosion-resistant, hygienic build — FRP vessels for pre-treatment, SS304 precision filter and wetted parts for durability and food-safety compliance.

• Fully customizable voltage & capacity — adapt the plant to your local power grid and scale from 250 L/H up to 50,000 L/H as your demand grows.

• Modular optional upgrades — dosing, UV sterilizer, SS storage tank, ozone generator, and ozone mixing tower for end-to-end pure-water lines.

  
  

Technical Specifications

Treatment Process

Raw water flows through a fully integrated, 7-stage treatment train:

1. Raw Water Tank & Booster Pump — provides a stable water source and consistent inlet pressure to the system.

1. Quartz Sand Filter — removes suspended solids, sediment, and divalent iron/manganese. Equipped with an automatic control valve for auto backwash.

1. Activated Carbon Filter — adsorbs color, odor, chlorine, and organics to improve taste and protect downstream membranes.

1. Water Softener — exchanges calcium and magnesium ions with cation resin to prevent scaling.

1. Precision Filter (≤5μm) — captures residual particulates, protecting the RO membranes from blockage and reducing power consumption.

1. Multistage High-Pressure Pump — delivers stable flow and sufficient pressure to the RO membrane system.

1. Reverse Osmosis Membrane System — rejects bacteria, viruses, dissolved salts, and ions, producing pure water that exceeds drinking-water standards.

Automatic & Safety Functions

• RO membrane auto-wash + manual wash

• Auto stop at high pure-water level / auto start at low level

• Multistage pump dry-run protection

• Power-off, under-voltage, over-current, short-circuit, and leakage protection

Capacity Options (Scale as You Grow)

The platform scales from small workshop units to large industrial plants. All models share the same proven process design.

Optional Accessories

Build a complete, end-to-end pure-water production line with these add-ons:

• Dosing System — flocculant for sedimenting colloids; scale inhibitor to protect membranes; pH-adjusting agent for ideal water chemistry.

• UV Sterilizer (SS304, 2000 L/H) — final-stage bacterial sterilization.

• Stainless Steel Water Tank (1,000–5,000 L+) — raw-water or product-water storage (pair with an ozone machine for stored-water sterilization).

• Ozone Generator (3–32 g/H, SS304) — produces ozone for tank/mixing-tower sterilization.

• Ozone Mixing Tower (SS304) — ensures thorough ozone-water mixing for maximum sterilization effect.

Applications

The RO plant serves a wide range of industries wherever pure water is essential:

• Bottled water / mineral water production

• Soft drink, juice, tea & beverage production

• Wine, beer & brewing

• Direct drinking water supply

• Pharmaceutical & hospital use

• Cosmetic production

• Food processing

• Irrigation & agriculture

• Paper-making, hotel & restaurant, automotive, iron & steel, wastewater treatment, and more
