Facing issues with your ETP/STP system? Scroll down to see how we fix it. Across India and Bangladesh, many ETP / STP / WWTP systems struggle due to high COD/BOD, colour, TDS, and frequent load variation — leading to unstable output, odour issues, and constant compliance pressure.
We design systems based on actual wastewater characteristics and site conditions, so performance remains stable in real operations — not just during inspection.
✔ Designed on actual effluent profile
✔ Handles shock load and seasonal variation
✔ Right process selection (MBBR / SBR / MBR / ASP)
✔ Suitable for new installation or fixing existing plants
Share your requirement (flow, industry, or issue) — we’ll suggest a practical approach with realistic costing.
How Does Our Industrial WWTP / ETP System Work?
Industrial wastewater is never the same. In textile and process industries across India and Bangladesh, load, colour, COD/BOD, and flow keep changing — which is why standard designs often fail.
We start with your actual wastewater data — parameters like BOD, COD, TSS, pH, oil & grease, TDS, and metals. Based on this, we define the right process, sizing, and treatment sequence for stable performance.
The system is designed in stages:
✔ Screening & Equalization – stabilizes flow and load
✔ Primary Treatment – removes solids, colour & chemical load
✔ Biological Treatment – MBBR / SBR / MBR / ASP as required
✔ Tertiary Treatment – filtration, UF or RO for final polishing
Proper equalization, controlled dosing, and balanced biological design help the plant handle variation without frequent issues.
Automation and sludge management are planned to keep operation simple, reduce dependency, and maintain consistent compliance.
With execution support from Kolkata and experience across India and Bangladesh, the focus stays on real performance — not just initial commissioning.
SCREENING & PRE-TREATMENT
Removes debris, oil, grease, and grit to protect equipment and ensure smooth downstream operation.
EQUALIZATION & pH CONTROL
Balances flow, load, and pH to stabilize treatment.
PRIMARY PHYSICO-CHEMICAL TREATMENT
Removes suspended and colloidal pollutants via coagulation, flocculation, and clarification.
BIOLOGICAL TREATMENT
Reduces BOD/COD through controlled biological processes.
TERTIARY / POLISHING TREATMENT
Polishes effluent to meet discharge or reuse standards.

WWTP / ETP / STP Performance & Lifecycle Support
Stable WWTP / ETP performance depends on proper wastewater analysis, hydraulic balance, and correct process integration — not just equipment replacement. In textile and industrial plants across Bangladesh and India, failures often come from poor equalization, load variation, and weak process design.
Our EPC and retrofit approach starts with plant audit — covering COD, BOD, TSS, TDS, color, flow variation, HRT, and aeration performance. Based on this, we optimise equalization, biological process (MBBR / SBR / MBR / ASP), chemical dosing, and tertiary treatment.
Scope includes design correction, retrofit execution, equipment integration, automation tuning, and performance trials under actual conditions — ensuring stable compliance and reliable operation.
Focus is on long-term stability, lower operating cost, and consistent performance — not just temporary compliance.

Our WWTP-Centric Approach
Plizma Technology follows a process-first, compliance-focused approach for Industrial Wastewater Treatment Plants. Each system is developed after understanding actual effluent quality, process variation, load fluctuation, discharge requirements, and reuse or ZLD objectives — rather than relying on standard assumptions.
The focus remains on achieving stable treatment performance, controlled plant operation, and minimizing operational issues after commissioning.
We integrate physical, chemical, biological, and advanced treatment stages with practical equipment selection, flexible layouts, and provision for future expansion or stricter norms. Designs are kept adaptable, considering that industrial loads and regulatory requirements evolve over time.
This execution-oriented approach has supported projects across Eastern India and Bangladesh, with consistent focus on long-term performance and compliance reliability under real operating conditions.
