2.2 Composition of Synthetic Wastewater
Synthetic wastewater was prepared which consists of glucose used as source of carbon
and a main ingredient to organic matter. Potassium nitrate and potassium di-hydrogen
phosphate were added in wastewater to provide enrichment as nitrogen and phosphorus source, respectively. Synthetic wastewater was seeded with bacteria culture
that was aerated for 15 days for microbial growth. Growth of the bacteria also depends
on the availability of oxygen. Supply of oxygen was done by air diffuser. Detailing
of five batches used for different concentration of COD, nitrate, and phosphate is
given in Table 1.
