STP and ETP Plant Manufacturer in Sivasagar

ONGC oilfields across Nazira, Geleky, and Lakwa extract thousands of barrels of crude oil daily. Produced water co-extracted with crude petroleum contains heavy concentrations of emulsified hydrocarbons, dissolved polyaromatic compounds, heavy clays, and extreme chlorides.

Discharging untreated oily water into local agricultural fields or tributaries flowing toward the Dikhow River contaminates regional paddy soils and causes severe aquatic toxicity. The Pollution Control Board of Assam (PCBA) strictly mandates captive primary and secondary treatment with continuous monitoring.

Trity Enviro builds specialized oilfield chemical effluent treatment plants equipped with corrugated plate interceptors, automated oil skimmers, and advanced Dissolved Air Flotation (DAF) systems. Micro-fine bubbles float emulsified crude droplets to the surface, recovering valuable oil while reducing hydrocarbons to below 5 mg/L.

Clarified wastewater then undergoes biological polishing in Moving Bed Biofilm Reactors (MBBR) where specialized microbial cultures digest residual dissolved hydrocarbons. Dewatered oily sludge is processed through filter presses for authorized bioremediation handling.

Alongside its heavy petroleum operations, Sivasagar supports extensive residential townships, executive housing colonies, and commercial facilities in Nazira housing thousands of ONGC personnel. These settlements generate high daily volumes of domestic greywater and blackwater.

With water conservation priorities intensifying across eastern Assam, treating and recycling sewage water in-situ provides vital operational security. Reusing treated water for drilling mud preparation, site dust suppression, and green belt cultivation conserves millions of liters of fresh river water daily.

Our prefabricated sewage treatment plants utilize modern MBBR and MBR biological technology. Submerged fine bubble aeration maintains active biological cultures that rapidly digest organic matter without offensive septic odors, while ultrafiltration membranes produce crystal-clear, pathogen-free permeate.

For industrial townships, executive colonies, and commercial complexes requiring dependable drinking water, we install high-efficiency commercial RO plants. Treated effluent is recirculated for green belts, toilet flushing, and cooling towers, delivering long-term utility savings.

Operating in an environmentally sensitive Upper Assam river basin requires continuous technical diligence. Many oilfield processing terminals in Sivasagar are adopting zero liquid discharge architectures to insulate their operations against future regulatory restrictions. Trity Enviro delivers turnkey zero liquid discharge plants integrating ultrafiltration, industrial RO plants, and thermal evaporators.

This closed-loop design recovers over 95 percent of industrial wastewater as high-purity water for boiler feed and cooling systems while converting separated salts into dry solids. Our engineering network coordinates with regional service centers in neighboring Jorhat and Dibrugarh to provide fast technical response.

We provide full-scope annual maintenance contract programs across Sivasagar, Nazira, and Geleky oilfield corridors. Our field engineers handle bio-culture maintenance, chemical dosing pump calibration, membrane clean-in-place cycles, and PCBA compliance testing.
