FAQ
Q1: What is the difference between single stage RO and double stage RO? A: Double stage RO adds a second reverse osmosis filtration after the first stage. It can reach much lower conductivity and higher purity of water, which is suitable for scenarios with strict water quality requirements. Single stage RO is for general purified water demand.
Q2: What raw water TDS can this 35m³/h double stage RO system handle? A: This double stage RO unit is designed for raw water with TDS below 2000ppm. We can customize the membrane configuration and pretreatment system if your raw water has higher TDS.
Q3: How long is the service life of RO membranes? A: Under proper operation and regular chemical dosing maintenance, RO membranes can work for 2–3 years. The service life depends on raw water quality and cleaning frequency.
Q4: Is this RO system fully automatic? A: Yes. It adopts PLC automatic control. It monitors pressure, flow and water conductivity online, with automatic stop and alarm functions under abnormal conditions. Manual operation is also supported.
Q5: Can you customize the capacity of reverse osmosis equipment? A: Absolutely. We provide custom RO systems from 1m³/h up to 100m³/h, including single stage, double stage RO and EDI ultra-pure water systems for different industries.
Q6: What after-sales service do you provide? A: We provide pre-shipment testing, installation drawings, remote guidance, operation training and lifetime technical support. Spare parts are available for supply.
