“…The result of ABR treatment similar to the result of anoxic treatment of piggery wastewater which produced COD removal for 54.5% for anoxic activated sludge and 51-60% for ABR [14,15]. As well as the result of NH3-N, removal which merely produced 50-58% of value.…”

ABR used to treat wastewater with high COD level such as livestock wastewater. ABR treatment consists of compartments which are limited by vertical bulkhead growth with attached bacteria. However, ABR treatment only capable degraded COD level by 50 – 53%. This value did not qualify to be discharged into the environment. Therefore, ABR treatment need further treatment with ozone treatment and aerobic activated sludge. There were two treatments in this study, which are ABR with ozone treatment and aerobic activated sludge (S1) and ABR with aerobic activated sludge (S2). COD degradation with ozone treatment showed low efficiency, 31.1 ± 1.5 % but BOD/COD level increased. Aerobic activated sludge with batch system showed efficiency of COD degradation as 95.3 ± 2.2 % (with ozone treatment) and 78.6 ± 4.5 % without ozone treatment. The final concentration effluent for livestock wastewater was 167.7 ± 62 mg/L. Aerobic activated sludge with continuous system was conducted to test that result and it average efficiency only decreased into 85%. This concentration was qualified to be discharged into environment.

Domestic wastewater provides the largest contribution to pollution both in terms of quantity and quality. Therefore, before being discharged into the environment, wastewater needs to be managed first. This study used the cultivation of microalgae Chlorella sp. and algae mix to manage domestic wastewater. The reactor used in the study was a 3L volume of water. The cultivation process was assisted by UV-A and UV-B with the air flow rate as much as 1.2 L/min. Pollutant parameters being focused on were NH3-N and PO4-P nutrient parameters. Allowance for NH3-N by Chlorella sp. and algae mix were 54.9% and 49%, respectively. Allowance for PO4-P by Chlorella sp. and algae mix were 70.2% and 57.1% while biomass of Chlorella sp. and algae mix increased 85.5% and 98.9%. Specific growth rate of Chlorella sp. and algae mix were 0.025 h-1 and 0.027 h-1. As a control on biomass growth, turbidity value in the study also increased.

One of the types of tofu industries in Indonesia is that the small-scale tofu industry was located in the East Jombor, Ketapang Village, to be precise, on the Blorong River. The Simplified Tofu Industry, with a 1300 kg/day production capacity, produces liquid waste that is disposed of into the Blorong River with a BOD parameter of 2,726 mg/L, COD of 4,972 mg/L, and TSS of 388 mg/L.These values greatly exceed the quality standards based on the Regional Regulation of Central Java Province Number 10 of 2004 concerning Tofu Industry. The entry of these pollutants into the Blorong River, over time, can cause water bodies to become toxic and pollute the Blorong River. Therefore, one of the efforts to protect this river's environmental conditions is to increase the efficiency of the Wastewater treatment plant and substitute the determined fuel through alternative scenarios. In the MBBR scenario, substituting diesel fuel into biomass is a type of biodiesel. Biodiesel has an advantage for the fire tube boiler industry because it can reduce exhaust emissions compared to diesel. Meanwhile, the existing wastewater treatment is substituted for the MBBR unit. The choice of MBBR as a wastewater treatment unit is because it is economical, does not require large land, is simple in development design, and is accessible in operation and maintenance. In the second scenario (SBR), a transition of Diesel fuel to LPG. LPG as a fuel input in the cooking process will result in cleaner emissions, especially on the SO2 parameter, and better because it has a higher heating value than diesel, 47,3 Tj/Gg. Both scenarios are analyzed regarding the magnitude of the impact on the environment using the OpenLCA method. The resulting impact magnitude on the OpenLCA method from each alternative is evaluated to obtain the best scenario. In the Tofu Industry, the best design the resulting impact is smaller than the SBR alternative.
