Abstract

The study was performed to determine the effect of the blend of enzymes, organic catalyst and probiotics on the physico-chemical properties of swine wastewater collected from a commercial swine farm in Quezon Province. The experiment was composed of four treatments namely: treatment 1(n=3) no treatment given, treatment 2 (n=3) 25ml of treatment at week one, treatment 3(n=3) 25ml every week and treatment 4 (n=3) additional 25 ml every week. Dissolved oxygen in parts per million was measured daily using an oxygen meter. On the average, results showed that treatment one has decreasing amount of dissolved oxygen while treatments 2, 3 and 4 has increasing amount of dissolved oxygen. Change in color of the water from brown to dark brown and formation of sludge part at the bottom and a supernatant layer at the surface was observed. There were no distinct differences on the turbidity and odor except for the presence of fly larvae in treatments 1 and 2. Statistical analysis showed that there was a significant difference between treatment 1 to treatments 2, 3 and 4. Increase in dissolved oxygen was due to the proliferation of probiotics which increase the rate of decomposition of organic matter in waste water.
