Tamarind seeds (Tamarindus indica) as waste are rarely used until now and
needed to be developed further for river water which is more economical and
biodegradable. The use of tamarind seeds as
natural coagulant in river water treatment
been done. Study on the effect of tamarind as a natural coagulant on water quality
parameters which include: pH, turbidity and total suspended solid in river water by
using the coagulation
-
flocculation method. The
research variables are tamarind seed
measure ( 500, 1000, 1500, 2000 and 2500 mg/l), particle
diameter of tamarind seeds
(
20, 40, 60, 80 and 100 mesh). Result of the research explained that in the range of time
the observation was done, the tamarind seed
measure as an optimal coagulant being
1000 mg/l with particle diameter of tamarind seeds 100 mesh could removed 74,07%
TSS and 51,79% turbidity.
