Product Details
Engineered for continuous ultrapure water production, the 1000 LPH double stage RO EDI system is a fully automated, chemical-free solution that seamlessly integrates robust feed conditioning, efficient desalination, and advanced electrodeionization. The standardized process begins when a stainless steel raw tank supplies three automated SS304 vessels-a sand filter, carbon filter, and resin softener supported by a regenerating brine tank-before passing through a protective cartridge security filter. High-rejection desalination is achieved via a two-pass RO configuration where a primary high-pressure pump feeds two membranes and a secondary pump feeds one; this eco-friendly loop recycles second-pass concentrate back to the first-pass feed while monitoring conductivity at three strategic points. For the final polish, RO permeate flows through a pleated security filter into an EDI module that utilizes DC current for chemical-free ion removal, with final water quality strictly guaranteed by online resistivity monitoring and a terminal UV sterilizer for absolute microbiological control.

Advantages
The system offers exceptional operational advantages by delivering continuous, ultra-pure water through a sustainable, 100% chemical-free process that relies on DC current rather than hazardous acids or alkalis for regeneration. Its eco-friendly, two-pass RO design integrates a smart recycling loop that returns second-pass concentrate to the inlet, significantly increasing water recovery and reducing waste. Furthermore, the system maximizes lifespan and reliability through a heavy-duty stainless steel build (SS304 vessels) and automated backwash valves for maintenance-free pre-treatment, while ensuring strict quality compliance via multi-point conductivity sensors, online resistivity tracking, and terminal UV sterilization for absolute microbiological control.
FAQ
1: What are the water quality standards produced by the 1000 LPH double stage RO EDI system?
The 1000 LPH double stage RO EDI system is engineered to consistently produce premium ultrapure water. By combining dual-stage reverse osmosis (which achieves up to 99% initial salt rejection) with a chemical-free EDI module, the system delivers high-resistivity effluent (typically up to 15-18 MΩ·cm) and low conductivity. With its integrated terminal UV sterilizer providing strict microbiological control, the final output easily complies with stringent industrial, electronics-grade, and pharmaceutical water standards.
2: How does the chemical-free regeneration work in this system?
Traditional water systems require hazardous acid and alkali chemicals to regenerate exhausted ion-exchange resins. In contrast, the system utilizes an advanced Electrodeionization (EDI) module that employs DC current to continuously split water molecules into hydrogen (H+) and hydroxyl (OH−) ions. These electrochemically generated ions continuously regenerate the internal resin bed during operation, eliminating chemical costs, downtime, and chemical waste neutralisation.
3: What automated maintenance features are included to protect the membranes?
To ensure seamless operation and maximum membrane lifespan, the system features a fully integrated automation package. This includes independent automatic backwash valves on each of the three SS304 pre-treatment vessels (sand, carbon, and softener) for hands-free self-cleaning, an automated brine tank for resin regeneration, and dual-layer security filters (cartridge and pleated) to catch micro-particles. Additionally, the system continuously monitors safety via three-point conductivity sensors and an online resistivity tracker to prevent out-of-spec water from reaching the core modules.
