Introduction
ZH-RO Series RO Water Purification System
(Stainless Steel Membrane Housing + Scale Inhibitor | CE Certified)
Designed for medium and large-scale applications with complex water quality and high-load operation, the ZH-RO-2000/3000L RO System represents a premium upgraded solution. It offers flexible water production capacities from 500L to 3000L per hour, precisely matching the pure water demands of catering services, food processing, and industrial production lines.
The system features a core upgrade to a high-pressure resistant stainless steel membrane housing. Crafted from corrosion-resistant stainless steel, it is engineered to withstand the rigorous high-pressure environment of RO processes. Boasting superior sealing performance, it effectively prevents leakage, corrosion, and deformation. Compared to conventional membrane housings, it delivers a significantly extended service life, making it ideal for long-term, high-load operation in challenging water conditions.
Complementing the robust hardware is a professional intelligent anti-scaling system. Equipped with a precision metering pump, it automatically doses scale inhibitor based on real-time water flow. This proactive technology effectively prevents the formation and deposition of calcium carbonate, barium sulfate, and ferric hydroxide scales, protecting the RO membrane and pump components at the source and eliminating membrane fouling and performance degradation.
Powered by the standardized pretreatment process combined with advanced RO reverse osmosis technology, the system achieves an impressive 97-99% desalination rate. It deeply removes dissolved solids, colloids, organic matter, bacteria, and viruses, ensuring the produced water consistently meets stringent food-grade and industrial-grade pure water standards.
For seamless operation, the system is equipped with real-time monitoring via flow meters and pressure gauges, integrated into a centralized electrical control cabinet. It supports intelligent functions such as automatic start-stop and low-voltage protection, maintaining stable performance under operating conditions of 5-40℃ and a minimum inlet pressure of 0.25Mpa.
Thanks to the anti-fouling properties of the stainless steel membrane housing and the long-term protection of the anti-scaling system, the equipment enjoys an extended maintenance cycle and lower operational costs. It provides a durable, stable, and efficient pure water solution for medium and large commercial and industrial scenarios requiring reliable performance under complex and high-load conditions.eliable and long‑term water purification solution for medium and large‑scale water usage scenarios.
Application
Large catering chains, central kitchens in high-hardness/high-TDS water areas; meeting food-grade pure water demand for mass beverage production & food processing
Small chemical, electronic, hardware processing factories; adapting to industrial-grade pure water for production, cooling & cleaning
Large malls, comprehensive commercial complexes; providing pure water for catering, fresh food & drinking areas; suitable for high-load, uninterrupted water supply
Feature
250/500L/h dual flow options, matching water needs of different scales.
The stainless steel membrane shell and professional anti-scaling system work together to prevent corrosion and blockage, avoiding performance degradation and extending the service life of the RO membrane and pump.
Available in 500L–3000L models, the system supports continuous high-load operation and steadily produces food-grade & industrial-grade pure water even in complex water conditions.
Real-time monitoring, auto start-stop and low-voltage protection ensure stable performance. The easy-clean, anti-fouling membrane shell and anti-scaling system reduce fouling, lowering maintenance frequency and cost.
