Removalof turbidity in raw water by cactus (Opuntia Ellisana)
Abstract
Coagulation is an important process in water treatment to reduce the turbidity of water.
In this study, Opuntia ellisiana or more commonly known as cactus has been used to
evaluate its effectiveness in removing water turbidity by using jar test. The cactus is
used to study its potential in turbidity removal. Active component were extracted from
the cactus by using three different type of extraction solution namely distilled water,
Potassium Chloride (KCl) 1.0M and Sodium Chloride (NaCl) 1.0M. Initial synthetic
turbidity of 55 NTU was used for the study purpose. Other parameter such as pH has
also been studied. Cactus that is extracted by using Potassium Chloride (KCl) 1.0M
shows the highest efficiency in turbidity removal. Besides that, lower pH does help in
coagulation process.
