Abstract

The   present paper deals with   effectiveness of coagulation for  removal of turbidity and   biological  growth in experimental salt gradient solar  pond. The  result obtained indicated that  coagulation is  not  able   to bring down   the turbidity below   1 NTU,  while   at 10 NTU  starting turbidity, the optimum  alum  dose  comes   out  to be 75  mg/I  and   it is  60  and   45  mg/l for 5  and 3  NTU  respectively. This acquired level of turbidity is  within acceptable  limits  for solar ponds, hence   the   experimentation with  higher dose   was  not  continued.
