Hazardous Industrial Sludge - Shanghai, China

***Hazardous Sludge Waste Treatment***: Our client produces 100,000 tonnes per year of stainless steel acid sludge (hazardous waste, containing high concentrations of several toxic heavy metals) which had previously been taken to landfill. ***Treatment***: RAW Shanghai initially carried out treatability trials on the hazardous waste material using our bespoke designed reagents to provide our client a steel manufacturing company with the most cost effective treatment that met their treatment criteria. The treatment involved five main process stages: - Sludge conditioning (reach 0-75mm) - Homogenising and computer controlled reagent injection - Specific Designed Reagent RAW C/P11) - Treated waste curing - Secondary physical grading and screening(reaching <3mm) The treated material was validated using an independent accredited laboratory and the quality of the treatment process met the standards set out in: - The identification standard of hazardous waste – identification of hazardous toxicity (GB 5085.3-2007) - The Integrated Waste Water Discharge Standards (GB8978-1996) - Discharge standard of water pollutants for the iron and steel industry
