charge neutralization. Besides, as a polymeric coagulant, the bridging action of PAFC is also benefit for the coagulation. Hence, this study used low-cost and non-polluting quartz sand (also used in filter beds in drinking water plants) combined with AlCl3, FeCl3or PAFC to removeM. ...
Three filter materials, sand and biochars from cocoa pod husk and coconut shell as the precursor material were used in the columns as packing materials. For the production of the biochars, each precursor material was subjected to slow pyrolysis in an electric kiln with an average heating rate of...
