Working Process
- Feedwater Pretreatment
Raw water undergoes prefiltration (e.g., sediment filters, carbon blocks) and chemical dosing (antiscalants) to meet RO feed requirements (turbidity <1 NTU, chlorine <0.05 ppm). - Low-Pressure Separation
- Low-energy pumps pressurize feedwater to 50–100 psi, minimizing power consumption.
- The thin-film composite (TFC) polyamide layer rejects dissolved salts (≥98%), organics (MW >150 Da), and microorganisms.
- Product and Concentrate Streams
- Permeate: High-purity water flows to storage tanks for direct use.
- Concentrate: Efficiently discharges contaminants, with optional partial recycling to improve water recovery.
- Energy-Saving Design
Optimized flow channels reduce energy loss, while compatibility with solar-powered systems enhances sustainability.
- Feedwater Pretreatment
