| Summary: | ABSTRAK
Generally the objective of the biologically wastewater treatment is to remove the nonsettleable colloidal solids and to stabilize the organic materials. For industrial wastewater, the objective is to remove or reduce the concentration of impurities, i.e. organic and inorganic compounds. The anaerobic wastewater treatment process is an effective method to remove many organics materials in wastewater.
The milk industrial wastewater include PT. Sari Husada is composed form high concentration of organic materials like proteins, carbohydrates, fats, greases etc. Therefore the wastewater treatment require that anaerobic processes be applied subsequently. The method used is Upflow Anaerobic Sludge Blanket (UASB) to product more sludge in the retention time.
The anaerobic tank of PT. Sari Husada has a low efficiency, e.i. 54.86 %. , caused by the shorter hydraulics retention time which is only 3.1 days, in fact the minimum is 8 days. The other factor are high temperature which more than 35° C. and alkalinity or pH range which more fluctuatively.
Anaerobic tretment of industrial wastewater like textile, paper, food and milk, sugar etc., has become an interisting alternative for the removal of waterpollution.
