US-Pakistan Center for Advanced Studies in Water has collaborated with Al-Rahim Textile Industries (ATI) Pvt. Ltd.,through the USPCASW-USAID funded research project, for wastewater treatment and reuse: approaching zero water discharge intextile wet-processing. At the completion of this project, one workshop is organized at ATI on 27th August 2019, involving ATI executives, directors and managers, to disseminate the outcomes and further consultation on the recommendations drawn from the project. The project Principal Investigator Dr. Tanveer Ahmed and Co-Principal Investigator Prof. Dr. Rasool Bux Mahar, led the discussion and presented the outcomes. With this project, effective Water Management System is developed at ATI to control water consumption, improve water efficiency, development of processes water balance and adoption of onsite water recovery and reuse in textile processing.
Moreover, each textile process at ATI was analyzed in order to characterize wastewater load from individual process and further its relationship with the mixed effluent reaching to effluent treatment plant (ETP), in order to develop efficient operating conditions of ETP. Various scenario of ETP operations were developed with the helpinitiated research, to improve its efficiency and further to provide organic free raw water for tertiary treatment and RO membrane filtration, that aimed to enhance recovery rate of reclaimed/RO treated water. The project also covered development of operating conditions of RO plant at ATI and potential option for the sustainable treatment and handling of RO rejected water. During execution of this project, another research project proposal was developed on ‘Anaerobic Co-Digestion of Industrial Wastewater Sludge’ in collaboration with ATI, which got awarded by HEC, Pakistan, for funding of 15 Million upto 2 years.
