Introduction: Printing and Finishing is the Most Complex Textile Wastewater Stream Textile printing and finishing is a $1.5+ trillion global industry, and the wastewater it generates is one of the most chemically complex industrial streams. A medium-sized textile printing and finishing plant (producing 50-200 tonnes/day of printed fabric) generates 1,500-5,000...
Introduction: Why Tailings Water is the New EPC Hot Topic Tailings storage facilities (TSFs) are the largest man-made structures on Earth, and the water they contain is the single largest wastewater stream in the mining industry. A single large-scale copper or gold mine generates 50,000-200,000 m3/day of tailings slurry, of...
Introduction: Coal-to-Chemicals as a Strategic EPC Vertical in the Gulf and ASEAN Coal-to-chemicals (CTC) is a $50+ billion global capex pipeline that converts coal, petcoke, or biomass into methanol, mono-ethylene glycol (MEG), olefins, and synthetic fuels via gasification. A single 3,000 tonnes/day methanol plant based on coal gasification generates 4,000-8,000...
Introduction: The Two Most Demanding Wastewater Streams in Oil Refining Oil refining is a water-intensive industry, and the two highest-strength wastewater streams -- the desalter effluent and the sour water stripper (SWS) overhead -- account for 40-60% of the total wastewater load in a typical refinery. A 200,000 barrels/day refinery...
Introduction: The Hidden Water Footprint of Cement Manufacturing Cement is the world's most consumed manufactured material after water -- 4.4 billion tonnes in 2025 -- yet the cement industry is one of the most water-intensive industrial sectors. Producing one tonne of cement requires 500-1,500 litres of water for raw material...
Introduction: The Hidden Wastewater Stream in Megaproject Concrete Production Concrete batching is the most water-intensive activity on any major construction site. A single ready-mix concrete plant producing 200 m3/hour of concrete consumes 150-180 m3/day of process water for mixer washout, truck chute flushing, aggregate moisture correction, and dust suppression. The...
