Effluent discharge from shrimp hatchery wastewater consists ammonia that has
impact on environment. This study aimed to develop low cost filtration system for
shrimp hatchery wastewater treatment. Sponge has been used to pre-treat the
wastewater mainly to remove the larger suspended solid. Sand and activated carbon
(with and without heat treatment) were used as filter media for the treatment process.
FTIR and SEM analysis were used to determine the morphology and surface chemistry
of activated carbon which acts as adsorbent in this process. The physical and chemical
properties of raw wastewater were determined and pollutant removal efficiency of
each media used in the filtration system were assessed. The findings show that, the
treated sand (with heat) and treated activated carbon (with acid and heat) promoted
a good removal of TDS (mg/L), turbidity (NTU) and TSS (mg/L), which are 33.8%,
73.2%, and 98.6%, respectively. The findings of this study can be a fundamental
knowledge for the development and improvement design of aquaculture wastewater
treatment in the future.
