Kingsley conducted a comprehensive training program on “Integrated Wastewater Solutions for Textile Wet Processing: Recycling, ZLD & MLD” on 10th September 2025 at Six Seasons Hotel, Dhaka. This program was organized in partnership with Solidaridad Network Asia, QStone Capital and Lenntech as the technical partner focused on wastewater recycling, Minimum Liquid Discharge (MLD) and Zero Liquid Discharge (ZLD), including selection criteria and financial considerations relevant to the textile wet processing industry.
Participation of Industry Leaders
The program was honored by the presence of distinguished representatives from some of the country’s leading industries, widely recognized for their environmental responsibility and dedication to sustainable practices. The active participation of 60 professionals underscored the significance of the event as a forum for knowledge exchange and industrial collaboration
High officials from the organizing institutions were also in attendance, including Mr. Asiqur Rahman, Chief Executive Officer, and Mr. Rajib Ul Haque, Chief Technical Officer of Kingsley; Mr. Mohammad Abdullah Yousuf Khan, Project Manager, and Mr. Sultan Mahmud, Project Officer of Solidaridad Network Asia; as well as Ms. Rucksar Tabassum, Project Manager of QStone Capital were also present in this program.
Program Highlights
Mr. Asiqur Rahman opened the session by introducing the concept of SMEP project, objectives of this training and thanked everyone for attending this program.
The training was conducted by Mr. Rajib Ul Haque, CTO of Kingsley, who delivered an engaging and in-depth session on environmental regulations, water scarcity, and corporate sustainability, guiding the textile sector towards effective ZLD implementation.
Key topics included:
- ZLD & Textile Wastewater: Covering complex wastewater chemistry such as dyes, pigments, sizing agents, surfactants, salts, and heavy metals, along with critical pollution parameters like COD, BOD, TDS, TSS, and Color.
- Membrane Technologies: Ultrafiltration (UF) for pre-treatment of ZLD, Reverse Osmosis (RO) as the primary desalination step, and advanced brine concentrators for further reject concentration. Strategies for RO reject management and compliance with ZDHC progressive limits were also discussed.
- Economic and Operational Insights: Capital and operational expenditure, energy consumption, and management of crystallized salts and sludge, including potential reuse applications.
- Future Trends & Innovations: Emphasis on water audits, pilot testing, AI-driven process optimization, and advanced membrane materials for enhanced ZLD efficiency.
- Pilot Demonstrations: Kingsley showcased two pilot projects—the Nano Filtration pilot module and an Electrocoagulation pilot unit. These practical dimension to the training session, reinforcing theoretical concepts with real-world applications.
Recognition and Feedback
All participants received certificates in recognition of their successful completion. Prior to that, a Q&A session was held, where participants actively expressed their interest, raised a number of inquiries regarding technology, received comprehensive and appropriate responses. The attendees’ enthusiasm and active engagement contributed significantly to the program’s success. Participants expressed their hope for more such initiatives, highlighting the importance of such programs in promoting sustainable industrial practices and contributing to a greener Bangladesh.
Commitment to Sustainability
Kingsley reaffirmed its dedication to equipping industry professionals with the knowledge and tools necessary for sustainable environmental management and regulatory compliance. Organizers and participants alike emphasized the value of continuing such training programs to foster practical knowledge sharing and industry-wide sustainability practices.
