The dairy industry is observed as one of the furthermost polluting industries. While processing 1 L of milk, 2-10 L of wastewater is generated. In India, around 286 large and small-scale dairy industries generate plenty amount of wastewater. The cyclic operation of fabricated sequencing batch reactor (SBR) curtails various parameters, such as BOD, COD and turbidity and were found to be 85.78%, 76.77% and 83.21%, respectively at 10 hr. As the detention time increases, BOD, COD and turbidity reduces. The fabricated sequencing batch reactor was modified by adding plastic media at the bottom of the reactor tank as a biofilm having a surface area of 2.7 m2. The main purpose of biofilm is to enhance the efficacy and bio-sludge superiority by increasing the bio-sludge in the process. The efficacies of removal of parameters were enhanced by using the biofilm sequencing batch reactor (BSBR) reactor under the high organic loading of 1340 g BOD5/m3 day. The COD removal of 89.3%, BOD5 removal of 83%, total Kjeldahl nitrogen (TKN) removal of 59.4% and oil and grease removal of around 82.4% was observed. Under the same high organic loading, curtailment of parameters was less in conventional sequencing batch reactor (SBR) [removal of COD- 87.0%, BOD5– 79.9%, TKN- 48.7% and oil and grease- 79.3%].
