Advanced STPs for Municipal & Large Infrastructure Projects

With 50+ years of combined expertise in wastewater treatment, Indus Ecowater delivers high-performance sewage treatment plants (STPs) tailored for municipalities, townships, industrial zones and large-scale infrastructure projects.

SBR (Sequential Batch Reactor)

SBR is a proven, high-capacity wastewater treatment technology engineered for municipal corporations, industrial estates, and large institutions. By integrating aeration and sedimentation within a single reactor, it enables efficient treatment with a smaller footprint, offering reliability, ease of automation, and compliance with stringent regulatory standards.

MBBR (Moving Bed Biofilm Reactor)

Designed for large-scale municipal and industrial wastewater treatment, MBBR systems utilize advanced biofilm carriers to handle high organic loads with minimal operator intervention. Its modular design makes it ideal for high-capacity installations, retrofits, and expansion projects requiring consistent performance and operational resilience.

Lake Remediation

India’s Lakes Are in Crisis. Across the country, water bodies are choking with untreated sewage, industrial effluents, and excessive nutrient loads. The result? Toxic algal blooms, foul odors, declining biodiversity, and dying ecosystems. While conventional treatment plants like SBR and MBBR exist, they often come with high costs, complex infrastructure, and intensive maintenance — making them impractical for many lake restoration projects.
