View details →
Standard RO skid, salt rejection ≥97 %, 0.5–50 T/H
View details →
50–200 T/H RO system with multi-stage membrane arrangement
View details →Process configuration follows the feed water analysis: softening ahead of RO for hard water, carbon or sodium bisulphite dosing for high chlorine, and EDI plus polishing mixed bed where high resistivity is required.

Selection requires feed hardness, daily consumption and peak flow. For hardness above 6 mmol/L or water high in iron and manganese, pre-treatment for iron removal is recommended.

Please provide floor height, number of households or design flow, and mains inlet pressure. Fire supply must be a separate system to code, with standby pumps.

Please provide flow, water quality, discharge standard and site conditions. In cold regions insulation or an indoor location is recommended, with access for sludge removal.

Flux is designed from water quality and operating mode, with on-line backwash and periodic chemical cleaning. Feed should pass 1–3 mm fine screening first.

Transmembrane pressure must be controlled with regular backwash and chemical cleaning (sodium hypochlorite plus citric acid). Oily or high-solids feed needs flotation or settling first.

Toray ROMEMBRA spiral elements — high rejection at low pressure
View details →
DuPont FilmTec elements — stable rejection, fouling-resistant options
View details →
BW and LP brackish water membranes — low pressure, good rejection
View details →Element selection depends on feed salinity, temperature, SDI and free chlorine. Control recovery and dose antiscalant in operation; store elements away from light and frost.

Genuine IONPURE EDI stacks for continuous ultra-pure water without regeneration
View details →
Diagnosis, repair and regeneration to extend EDI stack life
View details →
Domestic EDI modules with power supply and controls, cost-effective
View details →EDI feed must be RO permeate (conductivity <10 μS/cm, hardness <0.5 mg/L, free chlorine <0.05 mg/L). For repair, please provide the fault symptoms and operating parameters.

Hard quartz sand that traps suspended solids and cuts turbidity
View details →
High iodine coconut carbon for chlorine, organics and taste removal
View details →
High-strength extruded carbon for continuous air and water treatment
View details →
Natural manganese sand for iron and manganese removal
View details →Fill quantities are calculated from vessel diameter and bed depth; standard packing is 25 kg or 50 kg. Backwash activated carbon thoroughly before use to remove fines.

Soak and convert resin in brine before filling. Polishing resin should be fed with RO permeate to avoid organic and chlorine fouling.
