Highly Contaminated Pet Products Waste Water Treatment and Recycling Project

A contract has been signed between Water Regime (Pvt.) Ltd. and NOVATEX Limited Karachi, for the treatment of their highly contaminated process wastewater and its recycling. The project has a capacity of 1800 m3/day. 

April 2020, Water Regime (Pvt.) Ltd. has signed a new contract with NOVATEX Limited for the recycling of their highly contaminated industrial waste of their pet resin and preform manufacturing facility at Landhi, Karachi. The project has the capacity of 1800 m3/day. The wastewater contain Mono Ethyl Glycol & PTA streams also include cooling tower blow-down. The project will produce ultrapure water in resulting of recycling. The wastewater contain high BOD and COD which is about 3000 & 8000 mg/lit respectively. 

Water Regime (Pvt.) Ltd. will execute this project on turnkey basis, a loaded treatment scheme has been proposed for such a high load of pollutant. The treatment scheme comprising of Hybrid Anaerobic Treatment, latest Aerobic treatment with extended facility, Chemical enhance primary treatment for cooling tower blow-down, Sedimentation, Adsorption, Effluent polishing with robust UF membrane technology and desalination to produce ultrapure process water for reuse. The treatment scheme is a combination of conventional, hybrid and latest technologies. The Effluent treatment plant will produce excellent results that will meet latest world’s effluent discharge standards and effluent polishing (Ultra-filtration) membranes will produce ideally suitable water for desalination membranes, the system will ensure the sustainability and consistency of qualitative and quantitative productivity. 

The main objectives of this project are to produce low cost ultrapure water for their process reuse with compare to outsourced water which will obviously cost effective and control economics, reduction in factory waste to enhance the environmental stewardship, reduction in outsourcing or fresh water intake to enhance their capabilities and freshwater stewardship.
