This research studied the efficiency of sand filter simple A filter with fast and slow sand filter for water treatment of aquaculture. Study on using waste water from ponds cultured tilapia. Design of reactor to a width of 15.24 cm height 150 cm and the water overflow 30 cm, the study found that the sand filter size 2 mm. 80 cm height suitable for filter tank design in this experiment. By the effective turbidity removal particles suspended solid, BOD, nitrate, nitrite and ammonia percentage 59.98 96.95 48.15 and 0.51 2.23 15.62 respectively. The commissioning of 56 minutes water volume 252 l filtrate and filtration rate of 14.87 cubic meters per square meter - hours. For slow sand filter in this experiment is the size of sand filter 1 mm height 120 cm, with efficiency in turbidity removal in suspended solid particles. BOD, nitrate, nitrite and ammonia percentage 84.24 97.91 61.82 and 0.74 6.14 22.63 respectively. The commissioning of 42 minutes water volume 72 l filtrate and filtration rate of 5.57 cubic meters per square meter - hours. The sand filter tank filter and BAE slow sand filter was designed this time can water the turbidity, temperature, pH, BOD and suspended solid particles As to this standard drainage from cultured freshwater pond The Ministry of environment and natural resources. But can"t ammonia removal according to standard criteria for nitrate and nitrite Water quality before the experiment is less than from the standard formulation.
