Hasil samping instalasi pengolahan air limbah di industri bioetanol menghasilkan limbah padat berupa activated sludge. Limbah ini dapat menimbulkan masalah apabila tidak ditangani dengan benar. Diantaranya adalah menurunkan kandungan hara dalam tanah dan mencemari sumber air bersih bila masuk ke badan sungai. Limbah activated sludge dari proses anaerobic biodigesterdi industri bioetanol dapat dimanfaatkan sebagai pupuk organik dengan proses pengomposan. Tujuan dari penelitian ini adalah mengetahui pengaruh jenis komposter dan waktu pengomposan dalam pembuatan kompos dari activated sludge limbah industri bioetanol terhadap kandungan pupuk kompos yang dihasilkan.Pada proses pengomposan digunakan bioactivator jenis EM4. Jenis komposter yang digunakan adalah komposter aerasi dan dan komposter non-aerasi. Waktu pengomposan yang digunakan adalah blanko, minggu ke-1, minggu ke-2, minggu ke-3 dan minggu ke-4. Dari hasil analisis didapatkan karakteristik fisik pupuk kompos yaitu suhu, pH, Kelembaban, C organik, N total, P total, K total, serta ratio C/N sesuai dengan SNI  19-7030-2004. Penggunaan kompoter jenis aerasi dan non aerasi menghasilkan kualitas pupuk kompos yang memenuhi SNI  19-7030-2004. Waktu pengomposan yang semakin lama memberikan kualitas pupuk kompos yang lebih baik.Side product of the waste water treatment plant in the bioethanol industry produces solid waste in the form of activated sludge.This waste can cause problems if not handled properly. Among them are reducing the nutrient content in the soil and polluting clean water sources when they enter river bodies. Activated sludge waste from the anaerobic biodigester process in the bioethanol industry can be used as organic fertilizer by composting. The purpose of this study was to determine the effect of composter design and composting time in making compost from activated sludge of bioethanol industrial waste on the content of compost produced. In composting process used an EM4 as bioactivator. The composter design used is an aerated composter and a non-aerated composter. The composting time used is blank, week 1, week 2, week 3 and week 4. From the analysis, it was found that the physical characteristics of compost were temperature, pH, humidity, C organic, total N, total P, total K, and the C / N ratio according to SNI 19-7030-2004. The use of aerated and non aerated design composters produces quality compost that meets SNI 19-7030-2004. The longer composting time will provide better quality compost.

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL

With the commissioning of the waste water treatment plant Nordkanal, which has been dimensioned for a design capacity of 80,000 population equivalents, new worldwide standards for the implementation of large membrane-activated sludge plants have been created both from a technical and from an economic point of view. The hitherto successful operation of this plant has already now contributed towards this technology becoming suitable for use in large waste water treatment plants. The now two years the waste water treatment plant Nordkanal has been in operation have once again demonstrated that even on a large scale, membrane-activated sludge plants are able to reliably produce purified effluent of excellent quality, while simultaneously providing a small-sized design. They prove advantageous everywhere small-sized designs are sought after and the purified effluent has to meet high or special requirements. Wherever purification requirements are intensified in the foreseeable future, whether with regard to the hygienisation of effluent, or in the framework of re-using purified waste water as industrial water or potable water or in order to protect natural drinking water resources from critical anthropogenic impacts, the membrane bioreactor process or membrane filtration is trend setting and will increasingly gain in importance.

The capacity and efficiency of the existing activated sludge waste water treatment plant at SCA Graphic Laakirchen AG needs to be enhanced due to an expected future increase in waste water flow and COD-load. For the case of an existing upper limit of COD discharges into the river, the COD reduction rate of the waste water treatment has to be increased to a degree which is unobtainable by biodegradation only. Laboratory and pilot plant trials using a moving bed biofilm technique and an activated sludge treatment combined with ozone treatment and subsequent biofiltration have been performed with the aim to increase the COD reduction capacity and efficiency of the plant. The results show that the COD reduction capacity of the existing activated sludge plant can be increased by more than 100% by integrating a moving bed biofilm pre-treatment stage into the plant. In addition, improved sludge separation in the secondary clarifier was established. A special benefit of the ozonation plus biofilter treatment is a controllable COD reduction between 20 - 90% related to the outflow of the activated sludge plant. It is concluded that by integrating the investigated treatment techniques in the existing activated sludge plant the future increases in waste water flow and COD-Load can be handled satisfactorily without increasing bioreactor volume.
