Product Description
Single Stage RO Desalination Equipment For Factory Circulating Water Treatment
Product Overview

This single-stage reverse osmosis desalination device is specifically designed for recycling and desalination of factory circulating cooling water. It effectively intercepts dissolved salts, suspended solids, colloids, and scale-forming ions in concentrated circulating water, reducing water salinity and preventing continuous salt accumulation in cooling towers. The treated fresh water can be reused as supplementary circulating water, significantly lowering factory tap water consumption and sewage discharge.

Core Advantages
  • Efficient Salt Interception: Single-stage RO membrane removes most soluble salts in concentrated cooling water, solving the problem of rising TDS caused by long-term evaporation and fundamentally suppressing pipeline scaling and equipment corrosion.
  • Compact Skid-mounted Design: Pretreatment, high-pressure host, and fresh water tank are integrated on one frame, occupying minimal space in circulating water pump rooms. Easy to transport and install without complex civil construction.
  • Intelligent Automation: Equipped with PLC control system for automatic membrane flushing, high/low pressure protection, liquid level linkage, and fault alarm. Unattended operation reduces daily manual management workload.
  • Significant Cost Reduction: Reuse of desalted fresh water greatly reduces new makeup water purchases, lowers wastewater discharge fees, and decreases scale inhibitor dosage in circulating water systems.
  • Industrial-Grade Reliability: Matched multi-media pretreatment filters remove mud, rust, and suspended matter from circulating concentrated water, effectively delaying RO membrane fouling and extending membrane element service life.
Process Flow

Circulating concentrated water collection tank → raw water pump → quartz sand filter → activated carbon filter → 5μm precision security filter → high-pressure pump → single-stage RO main unit → fresh water reuse tank → cooling tower circulating supplementary pipeline

Pretreatment Unit: Removes suspended impurities to protect RO membrane

Single-stage RO Host: Main desalination unit for separating salt ions from water

Concentrated Water Discharge: Small amount of high-salt concentrated water enters factory sewage station for further treatment

Technical Specifications

Customized processing capacity ranges from 1 to 100 cubic meters per hour, suitable for both small workshop cooling circulating water and large industrial park circulating water stations. The salt rejection rate of single-stage RO membrane exceeds 97%.

Features industrial anti-fouling RO membrane, 304 stainless steel frame and pipeline, and automatic dosing anti-scaling system. Operating temperature range: 10℃-40℃. Standard power supply: 380V/50Hz.

Application Scenarios
  • Recycle desalination of cooling tower concentrated water in machinery, chemical, plastic, and printing factories
  • Central air conditioning circulating water concentration reduction treatment for commercial buildings
  • Injection molding, die casting, and air compressor cooling water recovery
  • Circulating water system salt balance treatment for power plants and heating stations
  • Reuse pretreatment of low-concentration industrial cleaning wastewater
Customization & Support

Equipment water yield and softened pretreatment can be adjusted according to circulating water TDS value and daily water circulation volume. Containerized mobile type is available for outdoor layout requirements.

Core accessories including high-pressure pumps, RO membranes, and PLC control cabinet come with one-year warranty. Lifelong free technical guidance is provided for installation, commissioning, and routine membrane cleaning maintenance.

Complete operation manuals and equipment layout drawings are supplied for global industrial buyers.
