STP and ETP Plant Manufacturer in Durg

Industrial wastewater generated by agro-processing, rice mills, solvent extraction plants, chemical units, and casting foundries in Borai Industrial Area, Rasmada Industrial Estate, and Durg-Bhilai twin city corridor cannot be effectively treated by basic biological systems. Effluent from these operations carries high biological oxygen demand from grain washing, acidic wash liquor, oil and grease, and boiler blowdown, which quickly blinds conventional biological media, coats clarifier surfaces, and causes severe pump failure.

The presence of fluctuating pH levels, heavy suspended mineral fines, and emulsified oils demands a multi-stage physico-chemical and mechanical treatment train.

Trity Environ Solutions engineers primary treatment systems featuring automated bar screens, heavy-duty grit separators, and high-efficiency mechanical oil skimmers to capture free-floating oils before they enter downstream units. The wastewater then undergoes flash mixing and flocculation with automated chemical dosing systems injecting lime, polyaluminium chloride (PAC), and specialized polyelectrolytes.

Our lamella clarifiers and high-rate tube settlers provide extensive settling surface area in a compact footprint, separating sludge flocs rapidly.

The resulting settled sludge is pumped directly to membrane filter presses, dewatering slurry into dry cake for safe handling and compliance with state hazardous waste disposal protocols. For facilities generating refractory chemical oxygen demand or toxic solvent residues, we integrate chemical oxidation, Fenton reaction vessels, and activated carbon polishing columns to guarantee discharge purity.

Urban development across Durg Municipal Corporation limits, Mohan Nagar, Padmanabhpur, and medical institutions has created an urgent demand for dependable, decentralized sewage treatment. Hotels, hospitals, shopping malls, educational institutions, and residential townships face strict regulatory pressure from the CECB and municipal authorities to ensure zero untreated sewage reaches storm drains or the Shivnath River basin.

Traditional sewage treatment plants suffer from bulky civil footprints, high power consumption, and persistent odor problems that draw complaints from residents and guests. Trity Environ Solutions designs prefabricated and site-constructed packaged sewage treatment plants based on Moving Bed Biofilm Reactor (MBBR) and Membrane Bioreactor (MBR) technologies.

In our MBBR systems, high-surface-area polypropylene carriers remain suspended via continuous air aeration, providing resilient biological treatment capable of absorbing sudden hydraulic surges.

For installations requiring superior water clarity and space economy, our MBR plants combine aerobic biological breakdown with 0.04-micron submerged membrane filtration. The permeate is odorless, crystal clear, and completely free from suspended pathogens, making it instantly reusable in central air-conditioning cooling towers, toilet flushing systems, and landscaped green belts.

Every Trity Environ STP is backed by an Annual Maintenance Contract. Speak with our technical specialists to plan an STP for your facility.

The Shivnath River is an indispensable ecological and drinking water lifeline in Chhattisgarh. Due to intense industrial activity and cumulative wastewater discharge, NGT directives to eliminate untreated domestic and agro-industrial discharge into the Shivnath River basin.

Regulatory bodies are systematically tightening consent conditions, requiring water-intensive industries and red-category units to implement Zero Liquid Discharge (ZLD) systems that eliminate all wastewater outfalls.

A poorly designed ZLD plant can burden an industrial facility with excessive thermal energy and electrical bills. Trity Environ Solutions engineers energy-optimized, closed-loop ZLD treatment trains. Following primary physico-chemical and secondary biological purification, treated effluent passes through chemical softening and silica removal before entering multi-stage brackish water reverse osmosis (RO) systems. This membrane phase recovers 85 to 90 percent of clear permeate for direct re-injection into process lines.

The concentrated brine is further reduced through high-pressure disc-tube reverse osmosis (DTRO) or mechanical vapor recompression, passing into Multi-Effect Evaporators (MEE) and Agitated Thin Film Dryers (ATFD). Solid salts crystallize out as dry solids, leaving zero liquid effluent at your boundary wall. This closed-loop configuration insulates your factory against groundwater extraction curbs and prevents regulatory shut-down orders.
