RO & DM plants
Reverse osmosis 1–100 m³/h below 30 ppm TDS; two-bed and mixed-bed demineralisation below 1 µS/cm.
Groundwater in industrial belts around Dhaka is hard and high in iron. MHM builds skid-mounted RO, DM and softener plants with iron removal and pre-treatment, and effluent treatment plants that keep the discharge inside DoE limits. For the water already in your system we supply the treatment chemicals — scale and corrosion inhibitors, biocides and boiler chemicals — with dosing systems.
