Title: Pilot investigation for treatment of low temperature and turbidity
Abstract: The treatment of low temperature and turbidity raw water became one of primary intentions in water works.A full-scale study with conventional process was carried out to investigate the removal of turbidity and organic matters by changing coagulant.The result showed ferric chloride(PAFC) instead of polyaluminum chloride(PAC) could reduce 1/3 of the activated silicate coagulant aid dosage and the turbidity was under the limitation of 1 ntu.Meanwhile,the removal rates of DOC and SUAV was increased by 7.1% and 6.2% respectively.It was found that PACF has an obvious predominance for the treatment of low temperature and turbidity raw water.The information obtained from this work could provide technological support for production.
