Solutions
Custom-engineered industrial wastewater treatment systems — from preliminary screening to tertiary polishing, designed for compliance and water reuse.
Overview
Industrial effluent is among the most complex wastewater to treat — every sector generates a different mix of contaminants, at different concentrations, with different regulatory limits.
HPT designs Effluent Treatment Plants for industries across the spectrum — from textile dyeing units with high colour and TDS loads, to pharmaceutical plants with complex organic compounds, to food processing facilities with high BOD and grease.
Our ETP systems combine physical, chemical, and biological treatment stages in a configuration engineered specifically for your effluent characteristics — not adapted from a generic template. The output: compliant treated water ready for discharge or, where ZLD is the goal, for further concentration and recovery.

How It Works
Effluent from various process streams collected and equalised to average out flow and concentration variations before treatment.
Screening, oil & grease separation, and pH correction to protect downstream equipment and condition the feed.
Coagulation, flocculation, and clarification remove suspended solids and colloidal matter, reducing turbidity and TSS load.
Aerobic or anaerobic biological degradation of dissolved organic compounds — targeted BOD/COD reduction to permit limits.
Advanced oxidation, activated carbon adsorption, or membrane filtration for trace contaminant, colour, and odour removal.
Chlorination or UV treatment for pathogen removal where discharge or reuse standards require microbiological compliance.
Sludge thickening, filter press dewatering, and safe disposal or beneficial reuse — fully documented for regulatory compliance.
By Sector
Each industry sector presents distinct treatment challenges. HPT configures a treatment train that addresses the specific contaminant profile — not a one-size-fits-all approach.

What You Get
System designed from scratch around your actual effluent composition — no generic templates adapted to fit.
Output meets CPCB/SPCB General Standards or sector-specific standards as applicable at handover.
Where ZLD is the end goal, ETP is designed as the upstream stage — output quality optimised for RO and evaporator feed.
Advanced oxidation and activated carbon stages for colour, odour, and trace organic removal.
Chemical precipitation and separation systems for heavy metal removal and recovery from metal industry effluent.
PLC-controlled dosing systems for coagulants, flocculants, pH correction, and oxidants — precise and auditable.

Our Methodology
ETP design starts with your effluent — not with our catalogue. HPT conducts a full effluent characterisation: BOD, COD, TSS, TDS, pH, heavy metals, colour, and any sector-specific parameters.
We then design a treatment train that reliably achieves compliance under your actual operating conditions — including flow variations, batch discharges, and seasonal changes.
We've designed and commissioned ETPs for some of India's most challenging effluent streams. That experience shapes every design we deliver.
01
Full inlet analysis: BOD, COD, TSS, TDS, pH, heavy metals, colour, and any sector-specific parameters.
02
We design a configuration that reliably achieves compliance under your actual operating conditions — flow variations included.
03
Factory-built skids for each treatment stage, tested before delivery to minimise site installation time.
04
CPCB/SPCB test reports, NABL lab certificates, and as-built drawings delivered at project handover — not chased later.
