Water Treatment Plant

Typical Input Raw Water Specifications (Example values for a standard industrial feed) pH: 8.5 Total Dissolved Solids (TDS): 1,200 ppm Total Hardness (as CaCO): 312 ppm Alkalinity (as CaCO): 520 ppm Chlorides: 46 ppm Sulphates: 10 ppm Silica: 10 ppm Treated Output Water Quality Specifications pH: 7.0 “ 7.5 Electrical Conductivity: < 1 µS/cm (down to 0.056 µS/cm in high-purity polishing units) Resistivity: Up to 18.2 megohms-cm Hardness (as CaCO): 0 mg/L Sodium & Chlorides: 0 mg/L (or < 1.0 µg/L) Total Silica: 3.0 µg/L Core Process & Equipment Components 1. Pre-Treatment Unit: Multi-grade sand filters and activated carbon filters to remove suspended solids and organic matter. 2. Cation Exchange Bed: Uses Strong Acid Cation (SAC) resin to replace positive ions (Ca², Mg², Na) with hydrogen (H) ions. 3. Degasser Tower: Strips out dissolved carbon dioxide (CO) formed during cation exchange. 4. Anion Exchange Bed: Uses Strong Base Anion (SBA) resin to replace negative ions (Cl», SO„²», SiO) with hydroxide (OH») ions. 5. Mixed-Bed Polisher: Combines cation and anion resins in a single vessel (typical mix ratio of 50:50 to 60:40) for ultra-pure final polishing. 6. Regeneration System: Cation resin is regenerated with an acid (Hydrochloric acid HCl or Sulfuric acid HSO„). Anion resin is regenerated with an alkali (Sodium hydroxide NaOH).

General Technical Specifications (Reference for 250 LPH “ 500 LPH Systems) Capacity / Flow Rate: 150 LPH to 1,500+ LPH (Liters Per Hour) depending on commercial or industrial scale. Feed Water Source: Borewell, municipal supply, or raw surface water (max input TDS typically up to 2,000“3,000 ppm). Output Water Quality (Permeate): Total Dissolved Solids (TDS): < 100 ppm (or adjusted via TDS controller) pH Level: 6.5 “ 8.5 Water Recovery Rate: 30% to 70% depending on feed water quality and design.

Dosing/Metering Pumps: The heart of the system. Options include diaphragm, piston, or peristaltic metering pumps designed for low-to-high flow rates and corrosive fluids. Flow Rate: Measured in Litres per Hour (L/hr) or Gallons per Minute (GPM) / Gallons per Day (GPD). Pressure: Maximum operating pressure rated in PSI or bar. Accuracy: Typically ± 1% to ± 2% of the set volume. Chemical Storage & Preparation Tanks: Made from corrosion-resistant materials (such as HDPE, PP, or SS316) depending on the chemical (acids, alkalis, coagulants, chlorine, hydrazine, ammonia). Includes level indicators, drain valves, and optional mechanical or pneumatic agitators/mixers. Skid & Piping Assembly: Pre-plumbed, chemically compatible piping (PVC, CPVC, PTFE, or stainless steel) with check valves, relief valves, and back-pressure valves. Often configured as a duty/standby dual-pump setup to ensure uninterrupted operation during maintenance. Control & Instrumentation Panel: Ranges from manual stroke/speed adjustment to automated PLC-based control panels with digital displays. Integrates with real-time feedback loops (pH meters, flow meters, or ORP sensors) and safety alarms.

Service Flow Rate: Residential: Typically 1 to 15 GPM (Gallons Per Minute) or 1 to 4,000 LPH (Liters Per Hour) depending on household size. Commercial/Industrial: Ranges from 1 to 100 m³/h. Operating Pressure: Generally 0.2 to 0.6 MPa (or 30 to 100 psi). If inlet pressure drops below 0.2 MPa, a booster pump is required. Resin Volume & Capacity: Residential/Commercial Units: Typically 1.0 to 3.0 cubic feet of cation exchange resin, rated around 30,000 to 75,000+ grains. Industrial Units: 25 to 2,000+ liters of resin capacity.
