The Use of Moringa Oleifera Seeds for Black Water Treatment:Implications for Water Disposal

Researchers have studied Moringa oleifera commonly known as malunggay for a variety of uses most notably for water treatment. Studies have shown that the seeds of Moringa oleifera contain active constituents with an excellent coagulative property. It is in the light that this study was carried out to evaluate the effectiveness of Moringa oleifera seed powder in the treatment of blackwater effluent. In this study, wastewater samples were collected from Liceo de Cagayan University septic tank and were treated using pure Moringa oleifera seed powder and 50% Moringa oleifera seed solution. The researchers analyzed the wastewater samples for various parameters such as pH, turbidity, total hardness, TSS, COD, BOD, nitrates, phosphates, ammonia and total coliform. The results obtained showed that Moringa oleifera had caused increase values in most of the parameters, such as turbidity, nitrates, phosphates, total suspended solid, COD and BOD. Both concentrations were shown to be effective in reducing microbiological load and pH. Ammonia and total hardness also showed significant results. Therefore, Moringa oleifera seed can be considered as an alternative method for water treatment.
