Give your family pure, safe and great-tasting drinking water. Our domestic water purifiers combine RO + UV + UF + Mineral + Alkaline technologies in multi-stage purification to remove arsenic, lead, chlorine, bacteria, viruses and bad taste from your water supply.
Choose from wall-mounted, under-sink with pressure tank, hot & cold dispensers and cabinet models — all with genuine filters, smart LED indicators and reliable after-sales service. Free home delivery and installation available in Dhaka and across Bangladesh.
We design and install advanced Sewage Treatment Plants for residential complexes, hotels, hospitals, commercial buildings and industrial facilities. Our STPs use world-class technologies such as MBBR (Moving Bed Biofilm Reactor), MBR (Membrane Bioreactor) and SBR to remove organic pollutants, suspended solids and harmful pathogens.
Treated water can be safely reused for gardening, flushing, cooling towers and floor washing — reducing water bills and protecting the environment. Every plant is custom-engineered to your wastewater load, space and budget.
Industries such as textiles, dyeing, garments, pharmaceuticals, food processing and chemicals generate effluent that must be treated before discharge. We deliver complete ETP solutions — from physical and chemical treatment to biological polishing — ensuring your discharged water meets Department of Environment (DoE), Bangladesh standards.
Our engineering team conducts detailed effluent analysis, designs the right treatment train (equalization, coagulation-flocculation, aeration, clarification, sludge handling and filtration), and provides full installation, commissioning and operator training.
When your process demands very low TDS water, our Industrial Reverse Osmosis Plants deliver. Available from 500 LPH to 50,000+ LPH, our RO plants remove dissolved salts, heavy metals, bacteria and pyrogens — producing high-purity water for beverages, food processing, pharmaceuticals, textiles, boiler feed, ice factories and more.
We use premium spiral-wound TFC membranes, SS/UPVC piping, energy-efficient high-pressure pumps and PLC-based automatic controls with online TDS monitoring. Every plant is tested and calibrated before delivery.
We stock a complete range of spare parts and consumables: RO membranes (Filmtec, Vontron, Hydranautics), PP/CTO/UDF filter cartridges, filter housings, UV lamps & chambers, ozone generators, dosing pumps, high-pressure pumps, pressure vessels, FRP vessels, multimedia & activated carbon media, valves, flow meters, TDS meters and fittings — for all major brands and models.
Original products, competitive prices and expert guidance to choose the right replacement for your system.
Ground and surface water often contains iron, arsenic, manganese, hardness, turbidity and suspended particles. Our Water Treatment Plants convert raw water into clean, usable water for industries, commercial buildings, municipalities and communities.
Our WTP solutions include Iron Removal Plants, Water Softening Plants, Sand & Carbon Filtration, DM (Demineralization) Plants and package treatment systems. We analyze your raw water report, then design the right combination of aeration, filtration, softening and disinfection to match your exact requirement.
A water treatment plant is a long-term investment — protect it with professional maintenance. We offer preventive maintenance, breakdown service, membrane cleaning (CIP), filter replacement, chemical cleaning, plant modification, automation upgrades and operator training for all types of water and wastewater treatment systems.
Our rapid-response service team ensures minimum downtime and maximum plant life. Annual Maintenance Contracts (AMC) available with scheduled visits, priority support and genuine spare parts.
We combine engineering excellence, genuine products and dedicated service.
