The removal of nitrate and phosphate are key process issues in waste water applications. EC directives including the Urban Waste Water Directive and the Water Framework Directive are driving down acceptable standards for nutrient discharge. In clean water applications, the addition of phosphate to water in order to reduce the dissolving of lead into drinking water is a widespread current issue, with water companies taking different views about the need to monitor and control. These activities bring focus onto the original sources of nutrients in water and have led to the development of a range of systems to add or remove nitrates and phosphates from waste water and nitrates from clean water. This workshop brings together these strands with a range of presentations on regulatory drivers, nitrate sources, removal process design, and monitoring and control equipment.
