Accelerated seeded precipitation (ASP) is a means of removing salt compounds that lead to scale formation in reverse osmosis (RO) treatment of salt bearing waters. This paper describes the performance of an ASP process that uses in-situ generated calcium phosphate seed to remove calcium from waste brine resulting from the RO treatment of municipal wastewater. Based on computer modelling and the results of the laboratory trials, a pilot plant is being constructed for the treatment of municipal wastewater from Donald, a small Victorian town in the Wimmera Mallee Region, Australia. Operating results are expected by October 2010.
