Our Key Water & Wastewater Solutions

Effluent Treatment Plant (ETP)

Industrial effluent treatment plants are essential for industries to manage wastewater efficiently, reduce freshwater consumption, and achieve environmental sustainability. Weltreat Systems designs and installs customized ETP solutions that help industries reuse treated water, significantly lowering water acquisition expenses while ensuring compliance with stringent discharge regulations. By preventing harmful pollutants from entering water bodies, ETPs contribute to environmental conservation and demonstrate corporate social responsibility.​

Sewage Treatment Plant (STP)

Sewage treatment systems play a crucial role in filtering harmful contaminants and ensuring clean water reuse for commercial complexes, residential buildings, hospitals, and educational institutions. Weltreat Systems provides advanced STP solutions incorporating Membrane Bio Reactor technology that enhances treatment efficiency, reduces footprint requirements, and produces high-quality treated water suitable for various non-potable applications.​

Reverse Osmosis (RO) Plant

RO systems are fundamental for producing high-purity water required by pharmaceuticals, food and beverage industries, and other critical applications. Weltreat Systems designs customized RO plants that remove dissolved solids, contaminants, and impurities, delivering water with desired parameters for specific industrial processes. These membrane-based systems ensure better quality end products while optimizing operational costs.​

Ultrafiltration (UF) Unit

Ultrafiltration technology provides an effective barrier against suspended solids, bacteria, and viruses, serving as an excellent pretreatment solution for RO systems or standalone treatment applications. Weltreat Systems’ UF units enhance water quality, extend membrane life in downstream processes, and reduce chemical consumption, contributing to overall system efficiency and sustainability.​

Zero Liquid Discharge (ZLD) Systems

Zero Liquid Discharge represents the pinnacle of water conservation technology, eliminating liquid waste completely while maximizing water usage efficiency. Weltreat Systems designs sophisticated ZLD systems that can reduce water consumption by up to 98%, recycling and reusing wastewater to produce only solid waste for disposal. This approach delivers substantial benefits, including reduced disposal costs by up to 90%, significant water conservation, compliance with strict environmental regulations, and recovery of valuable materials from wastewater streams. For industries in water-scarce regions or facing high disposal costs, ZLD systems align profit and sustainability goals while minimizing environmental impact.​

Pressure Boost Up Systems

Maintaining consistent water pressure throughout industrial facilities is critical for operational efficiency. Weltreat Systems provides engineered pressure boost-up systems that ensure a reliable water supply at required pressures, supporting various production processes and utility needs.​
