| Abstract |
This field evaluation program was initiated with the overall objective of providing information on the behaviour of a full scale swirl degritter designed and constructed in accordance with the shapes and proportions developed during model studies. The swirl degritter was designed for the pre-treatment of river water prior to its entrance into the rising main in order to reduce wear and tear on the raw water pumps and also to reduce the solids loading of the rising main and that of the balance tank of the water treatment works. Results of the solids removal had been evaluated in terms of three parameters: solids larger than 0.2 mm - the classical size aimed at in grit chambers -, solids larger than 0.088 mm and total settleable solids. The field evaluation tests carried out at Tamworth, New South Wales, Australia, prove the validity of the system interms of its hydraulic efficiency. |
