Treating Liquid Waste Cattle Manure With Anaerobic Waste Treatment Technology WWTP UASB (Up-Flow Anaerobic Sludge Blanket)

Cattle farming is unavoidable for every region in all corners of Indonesia. These livestock entrepreneurs aim to meet the food needs of the surrounding areas for livestock meat. In Indonesia alone, the cattle population continues to increase to 18 million heads. However, due to the increase in the number of cattle, it provides the potential for waste that can pollute the environment. For example, in August 2021, residents of Sukahaji village, West Bandung were hit by a flood of cow dung that spilled from the sewer in a residential area. Not even just residents, for food processing industries such as PT. Greenfields contaminate farmed fish due to contamination of cow dung waste. Waste water from cow dung every 20 localized heads will cause environmental problems where this has been regulated in the Decree of the Ministry of Agriculture No. 237/KPTS/RC410//1991 concerning restrictions on livestock businesses that must carry out environmental evaluations. One cow weighing 400 to 500 kilograms can produce solid and liquid waste of 27.5 to 30 kilograms/head/day.

Kinds of Waste From  Cattle

In general, livestock waste comes from manure produced in the form of solid waste, liquid, or feed.

Solid waste from livestock waste is manure, dead livestock and entrails from slaughtering livestock,
Liquid waste is all livestock waste in the form of urine, washing livestock rearing equipment and contaminated water from livestock manure.
A lot of cattle farm waste is disposed of, 56.67 percent of which do not process it before being discharged into water bodies such as rivers and seas so that it can trigger environmental pollution. Most pollution by livestock activities comes from waste feces, urine, feed residues and water for cleaning or raising livestock. This has caused protests from the surrounding community, especially if the polluted water comes into contact with the skin, it causes itching and creates a pungent odor. Liquid waste from livestock contains high pH, ??TDS, TSS, COD, BOD, H2S Nitrite and Nitrate which are still below the quality standard of liquid waste.

Livestock Waste Reduction or Treatment Efforts

Improper sewage treatment will be a serious problem for the community, therefore it is necessary to treat waste before the livestock waste is discharged into water bodies. Therefore, all livestock waste, especially from manure from livestock, which contains many harmful compounds, especially can pollute water which is the main source for humans, and the water contains methane which is dangerous if inhaled or evaporated into the air. The large number of cows and the resulting dung waste requires the breeder to first collect the dung. Cow dung should not be thrown directly on the ground because if it is exposed to water then it flows to the surface of the water it can disrupt the ecosystem.

Cattle Manure Treatment with Anaerobic UASB

Wastewater treatment of cow dung and urine can be treated using the Anapak UASB industrial WWTP (Up-Flow Anaerobic Sludge Blanket) technology. With several advantages such as affordable manufacturing costs, low operating costs, high efficiency in reducing organic content in waste. Blackwater wastewater or derived from this waste is very good if it is treated with WWTP Anaerobic UASB technology because it has a high organic content in addition to producing water with low pollutant concentrations, it can also produce biogas which is useful as a source of additional energy for production. Meanwhile, solid waste from sewage sludge before being put into the anaerobic system can produce compost. Usually, before entering the anaerobic system, the sewage sludge is first separated from the solids and liquids with a Screw Press Dewatering Press.
