Open thickening installation[widgetkit id=2072]
The open thickening installation consists of a large tapered thickening silo, with a slowly rotating wheel and an overflow. In order to improve the dewatering properties, poly-electrolytic flocculant (PE) is added. The PE-treated fine particles sink down to the bottom, there they are pumped to the filter pressing belt. The water leaves the thickener through the overflow.
