Abstract

A very small percentage of small dairy farms in the Philippines have wastewater treatment before disposal. The Dairy Training Research Institute - University of the Philippines Los Baños (DTRI-UPLB) is small dairy farm that does not treat its wastewater. Economics restrictions are the main cause of the problem and Vetiver Reed Bed Systems could be a cheaper alternative. With this, a study was conducted to find out how it would perform well with dairy farm wastewater and the trend between the removal of nutrients and the age of the Vetiver Grass used. Also, a design of this kind of reed bed for DTRI-UPLB was and it was observed that a Vetiver Reed Bed System is very effective in treating the dairy farm's wastewater. The average removal efficiency is 35.41% for Total Suspended Solids (TSS), 93.53% for BOD for 5 days (BOD5), 64.93% for Total Phosphorus (TP), and 81.88% Total Kjeldahl Nitrogen (TKN). A trend between the removal efficiencies with the age of the Vetiver was established and the proposed design of the reed bed must have a 4-hour retention time.
