The effectiveness of garbage enzyme and effective microorganisms (em) solution in water treatment

Abstract

Laboratory incubation experiments were conducted to study the influence of Effective Microorganisms (EM) and Garbage Enzyme (GE) on the removal of ammonia (NH3). Accumulation of nitrite (N02) and nitrate (N03) from the reduction of NH3 were observed for duration of 96 hours. Analysis were made each 24 hours to determine the changes of concentration using Indophenols Blue Colorimetric Method for NH3 analysis, Photometric Detection Method for N02 analysis and Screening Method for N03 analysis, certified from APHA standard method. Both studies showed promising removal efficiency of NH3 with removal efficiency above 90 % at th 96 hour after treatment with EM/GE. The result indicates positively that nutrient recycling is possible by converting NH3 to N03 with treatment of EM/GE. It is deduced that treatment with GE with concentration ranging from 0.4 % - 0.8 % as a new alternative in treatment ofNH3 . The performance of GE in treatment ofNH3 can be enhanced through enzymatic engineering in future research.
