CPCB-compliant biological treatment systems converting raw sewage into reusable water. Designed for townships, campuses, and municipalities — fully documented at handover.
Overview
HydroPure Technologies designs and delivers sewage treatment plants that go beyond regulatory compliance. Our systems convert domestic and municipal sewage into treated water recoverable for irrigation, cooling, and flushing — turning a waste stream into a genuine operational resource.
From 25 KLD decentralised plants for residential complexes to 50 MLD municipal networks, we engineer every system for the specific sewage characterisation, intended reuse standard, and available footprint — with full CPCB documentation at handover.

How It Works
Bar screens and grit chambers remove large solids, rags, and abrasive particles to protect downstream equipment.
Gravity settling removes 50–70% of suspended solids and 25–40% of BOD before biological treatment.
Aerobic biological reactors (ASP / SBR / MBBR / MBR) degrade dissolved organics and reduce BOD/COD to target levels.
Secondary settlers separate biological sludge from treated effluent, returning biomass to the reactor.
Sand filtration, UV disinfection, and chlorination reduce pathogens and produce reuse-grade effluent.
Centrifuges or filter presses reduce sludge volume by up to 85% for safe disposal or land application.
Polished effluent meets CPCB standards for garden irrigation, flushing, cooling towers, and road washing.
Biological Cores
We select the biological core to match your capacity, footprint, and reuse standard — not the other way around.
Conventional biological process. High BOD/COD removal. Suitable for large-capacity municipal plants.
Compact, cycle-based biological treatment. Excellent nutrient removal. Suitable for medium-capacity applications.
High-density biofilm carriers in aeration tanks. High throughput in compact footprint. Ideal for space-constrained sites.
Combines biological treatment with membrane filtration. Produces highest-quality effluent. Ideal for reuse applications.
What You Get
Consistent effluent quality meeting CPCB Class B standards for unrestricted irrigation and urban reuse.
UV and chlorination stages reduce total coliform to < 230 MPN/100 mL for safe discharge.
Tertiary polishing enables high-quality reclaim for cooling towers, flushing, and landscaping.
Fine-bubble diffusers and variable-speed blowers cut aeration energy by up to 35% vs. surface aerators.
Pre-fabricated skid modules reduce civil work and compress site timelines to weeks, not months.
All plants handed over with CPCB test reports, calibration certificates, and as-built documentation.

Standards
Every HydroPure STP is designed and commissioned to meet Central Pollution Control Board (CPCB) General Standards for Discharge of Environmental Pollutants — Class B treated sewage for land irrigation and industrial reuse.
Compliance certificates, NABL-accredited lab reports, and calibration records are part of the standard handover pack — not optional add-ons.
| Parameter | Limit (HPT Target) |
|---|---|
| BOD (5-day, 20 °C) | < 20 mg/L |
| TSS | < 30 mg/L |
| pH | 6.5 – 9.0 |
| Total Coliform | < 230 MPN/100 mL |
| Faecal Coliform | < 100 MPN/100 mL |

Our Methodology
01
Flow-composite sampling determines sewage strength and variability before process design begins.
02
We match ASP, SBR, MBBR, or MBR to your footprint, capacity, and intended reuse standard.
03
Structural, mechanical, and electrical skids are factory-built and tested before site assembly.
04
Full trial runs, performance certification, and operator training before formal handover.
