Toxic metal removal from wastewater sludge

该项目旨在有效地去除废水污泥中的有毒金属。污泥管理是水公用事业的一个问题，产生大量成本。污泥土地利用是一种可持续的污泥管理方式，但有毒金属的存在阻碍了污泥的长期重复利用。该项目的无化学品和正能量技术是基于使用酸化亚硝酸盐处理废水污泥。研究结果将有助于水务公司可持续地管理污泥，并为水务公司带来巨大的经济、环境和社会效益。

This project aims to efficiently remove toxic metals from wastewater sludge. Sludge management is a problem for water utilities, incurring substantial costs. Land application of wastewater sludge is a sustainable way of sludge management, but toxic metals hinder its long-term repeated application. The project’s chemical-free and energy-positive technology is based on the treatment of wastewater sludge using acidified nitrite. The outcomes will help water utilities to sustainably manage sludge and could bring large economic, environmental and social benefits to the water utilities.
