Sewerage Treatment

Decentralized Modular STP technology

Powertech’s ISR (Inert Solid Removal) Modular STP Technology offers a cutting-edge, decentralized wastewater treatment solution that operates directly on existing drains and nullahs—eliminating the need for land acquisition or new sewage conveyance systems. Designed for rapid deployment and easy scalability, the ISR system uses advanced enzymatic treatment to dramatically lower Biological Oxygen Demand (BOD) and minimize sludge generation, all while maintaining a short Hydraulic Retention Time (HRT). Integrated tertiary filtration ensures a clear, odor-free effluent, making ISR an efficient and sustainable choice for urban and semi-urban sanitation challenges.

Powertech is continuously enhancing its ISR technology through the integration of IoT, automation, and AI for intelligent monitoring and precise process control. In parallel, the company is refining bioremediation agents and optimizing filtration media to deliver superior treatment performance, higher operational reliability, and reduced lifecycle costs.

Primary to Tertiary

Integrated train slashes land use by 70 %.

No Odour, No Noise

Safe for dense urban sites.

Scalable Modules

Expand from 0.5 MLD to 5 MLD as demand grows.

Benefits of ISR technology

Direct installation on existing drains without the need for new pipelines or pumping stations.
Produces clear, odor-free effluent, ideal for safe discharge or reuse in non-potable applications such as irrigation, groundwater recharge, industrial processes, toilet flushing, and cooling towers.
Rapid deployment, greatly reducing installation timelines.
Incorporates tertiary treatment with advanced filtration tanks for superior effluent quality that meets the strictest discharge standards.
Offers scalability and adaptability, making the system suitable for both urban and rural applications.
