Product Details
The 1500 LPH UPVC RO EDI system is an industrial high purity water production unit that combines reverse osmosis (RO) membrane separation technology with electrodeionization (EDI) purification. feed conditioning – Raw water from a 2 m³ tank passes through three UPVC vessels: sand filter, activated carbon, and cation softener. Each vessel has an automatic backwash valve. A brine tank supports regeneration. A cartridge security filter protects the RO.
Two‑pass RO – First pass: a high‑pressure pump pushes feed through three TF‑8040 membranes in UPVC housings. Second pass: a second pump pushes first pass permeate through two TF‑8040 membranes. Second pass concentrate returns to first pass feed. Conductivity is monitored at three points.
EDI finishing – Second pass permeate goes through a pleated 0.1 µm filter then two EDI modules. DC power removes ions – no chemicals. Resistivity is monitored online. A UV sterilizer provides microbiological control.
Automation and storage – A PLC with 7‑inch touch screen controls pumps and valves. Product water is stored in 4T and 2T aseptic tanks. All interconnecting pipes are UPVC Schedule 80.

FAQ
1. What water quality is required for feeding the 1500 LPH UPVC RO EDI system?
Recommended feed water conditions:
● SDI <5
● Turbidity <1 NTU
● Iron <0.1 ppm
● Chlorine <0.1 ppm
Softener capacity can handle hardness levels up to approximately 300 ppm depending on operating conditions.
2. How often should the consumable components be replaced?
Typical replacement intervals:
● RO membranes: 2–4 years
● EDI modules: 5–8 years
● UV lamp: 8000–9000 hours
● Activated carbon: 2–3 years
Actual replacement frequency depends on feed water quality and operating conditions.
3. Can UPVC materials withstand RO operating pressure?
Yes. The UPVC Schedule 80 piping system is designed for industrial pressure applications. Typical RO operating pressure is approximately 0.8–1.2 MPa depending on feed water characteristics.
4. Can this RO EDI water purification system be expanded?
Yes. The system can be upgraded by increasing membrane quantity, pump capacity, and EDI modules. PLC programming supports future expansion.
5. Do you provide installation documents?
Yes. Engineering documents include:
● P&ID diagram
