Introduction
Ekok Syndicate is one of Bangladesh's most trusted providers of Effluent Treatment Plants (ETP) — designing, supplying and commissioning turnkey systems for textile, dyeing, pharmaceutical, tannery, food, chemical and paper industries. Every ETP we build is engineered to meet ECR-2023 and Department of Environment (DoE) discharge standards, while keeping running cost, chemical dosing and sludge volume as low as possible.
What is an Effluent Treatment Plant (ETP)?
An Effluent Treatment Plant is a specialised facility that treats industrial wastewater — known as effluent — to remove pollutants before it is discharged to a river, drain or sewer. A well-designed ETP uses a combination of physical, chemical and biological processes to reduce COD, BOD, TDS, colour and toxic load so the outlet water safely meets national environmental standards.
Levels of treatment in an ETP
A modern ETP works in three progressive stages, each removing a different class of pollutant:
- Primary: screening, equalisation, coagulation, flocculation and pH correction to remove suspended solids and colour.
- Secondary: biological treatment (SBR, MBBR, MBR or activated sludge) that lets microorganisms digest dissolved organic matter.
- Tertiary: sand and carbon filtration, disinfection and, where required, RO polishing to hit stricter reuse or discharge limits.
Popular ETP technologies we deliver
We select the treatment train based on your effluent character, footprint and reuse plan:
- MBBR — compact, robust, ideal for variable loads.
- SBR — high-quality output with a small footprint.
- MBR — the highest effluent quality, suitable for reuse and ZLD.
- Conventional physico-chemical + ASP — the most cost-effective baseline.
Why choose our ETP solution
Every plant is delivered turnkey — process design, civil, mechanical, electrical, instrumentation and start-up — with a written performance guarantee. Our AMC team keeps it running efficiently long after commissioning, so you stay compliant year after year without surprise shutdowns.
