200 Tons/hour Large-scale Reverse Osmosis Unit: Regional Industrial Water Treatment Hub

200 tons/hour large-scale reverse osmosis unit is an ultra-large water treatment hub developed for regional shared water supply projects. It supports research on the Application of RO equipment in power plants, and acts as a premium expansion alternative for operators running 100 tons/hour reverse osmosis system. Designed for round-the-clock heavy industrial operation, this unit delivers stable massive pure water for energy bases and cross-factory industrial water supply hubs.

Product Description

200 tons/hour large-scale reverse osmosis unit belongs to ultra-large integrated water treatment equipment with a rated pure water output of 200 cubic meters per hour. It targets regional shared water supply hubs, large energy chemical parks and centralized boiler water supply bases serving dozens of enterprises. Many regional water plants rely on multiple sets of medium and large RO equipment combined for water production, leading to complicated pipeline networks, difficult unified energy consumption control and high labor operation costs. This single ultra-large unit effectively solves such systematic operational challenges.

The unit adopts multi-group membrane train parallel modular integrated framework. For thermal power matching projects, our design team can draw on mature experience from the Application of RO equipment in power plants. Multiple independent membrane trains adopt distributed control architecture. Water plant operators upgrading from 100 tons/hour reverse osmosis system can obtain complete water balance simulation and transformation comparison data. All finished units complete long-cycle continuous heavy load testing and acceptance according to unified industrial RO equipment acceptance criteria before delivery.

Working Principle

200 tons/hour large-scale reverse osmosis unit operates on multi-train parallel pressure-driven membrane separation technology. Raw water enters multi-stage graded pretreatment assemblies to intercept suspended sediment, scaling ions and oxidative pollutants, providing comprehensive protection for massive built-in RO membrane elements. After precision security filtration, raw water is pressurized by matched multi-group high-pressure pump sets and evenly distributed to each membrane housing through high-precision balanced manifold pipelines.

Driven by hydraulic pressure exceeding natural osmotic pressure, water molecules penetrate semi-permeable polyamide membranes to generate qualified pure water. Dissolved salts, colloids, organic pollutants and microorganisms are intercepted and discharged with concentrated brine. The main PLC controller carries out staggered automatic flushing on each independent membrane train to prevent simultaneous flushing causing sharp fluctuation of total water yield. Optimized process layout enables the whole unit to maintain recovery rate ≥75% under long-term non-stop heavy industrial operation.

4. Customized multi-scene structural configuration:

Standard framework adopts heavy-duty anti-corrosion stainless steel. For flammable and explosive chemical zones, we can implement overall transformation to build explosion-proof industrial RO equipment.

5. Ultra-heavy continuous industrial design:

Developed for 24-hour uninterrupted heavy-load operation. The control system automatically adjusts running parameters to stabilize effluent indicators under raw water quality fluctuation.

Product Advantages
