Knit Concern Group Effluent Treatment Plant (ETP) Project – 2,500 m³/day

Charm Ltd. successfully designed, supplied, installed, and commissioned a 2,500 m³/day Effluent Treatment Plant (ETP) for Knit Concern Group in Godnail, Narayanganj, Bangladesh. The plant utilizes advanced Membrane Bioreactor (MBR) technology to treat industrial wastewater efficiently, helping the client meet environmental compliance requirements while supporting sustainable textile production.

Designed to handle the complex characteristics of textile wastewater, this ETP delivers consistent treatment performance, superior effluent quality, and reliable operation with a compact footprint.

Project Information

Project Overview

The textile industry generates wastewater containing dyes, chemicals, detergents, suspended solids, and biodegradable organic matter. Effective treatment is essential to prevent environmental pollution and comply with wastewater discharge regulations.

To address these challenges, Charm Ltd. implemented a 2,500 m³/day MBR-based Effluent Treatment Plant for Knit Concern Group. The system is engineered to provide efficient biological treatment combined with membrane filtration, producing high-quality treated water suitable for safe discharge and potential non-potable reuse.

Why an ETP Is Essential for Textile Industries

Textile manufacturing processes such as dyeing, washing, bleaching, and finishing produce wastewater containing a variety of pollutants. Without proper treatment, these contaminants can negatively impact rivers, groundwater, aquatic ecosystems, and surrounding communities.

Installing an Effluent Treatment Plant helps textile manufacturers:

Why Charm Ltd. Chose MBR Technology

Charm Ltd. selected Membrane Bioreactor (MBR) technology because it combines biological wastewater treatment with advanced membrane filtration, delivering exceptional treatment efficiency within a compact system.
Compared to conventional treatment methods, MBR systems provide higher effluent quality, lower suspended solids, and more consistent performance, making them an ideal choice for textile industries with stringent wastewater treatment requirements.

Benefits of MBR Technology

High removal efficiency for BOD and COD
Excellent removal of Total Suspended Solids (TSS)
Excellent removal of Total Suspended Solids (TSS)
Compact system design requiring less installation space
Reduced sludge generation
Stable operation under varying wastewater loads
Effective removal of bacteria and microorganisms
Lower environmental impact
Easy automation and monitoring
Long service life with reliable performance
Potential for industrial water reuse
