The Effect of Acid Treatment on Diatomite and Its Application in Treating Semenyih and Langat River Water
The water quality in the rivers of Malaysia is slowly deteriorating, often, high turbid water intake in water treatment plant causes overloading thus raising water treatment cost. Therefore, this study will provide an insight into the application of acid-treated diatomite in treating turbid river wa...
