Produksi daging babi di Indonesia semakin meningkat seiring dengan permintaan dan pasar. Hasil samping dari kegiatan tersebut adalah air limbah olahan babi yang mengandung bahan organik dan lemak yang sangat tinggi sehingga sulit untuk diolah. Pengolahan air yang mudah dan murah perlu diaplikasikan, mengingat pelaku usaha ini didominasi industri rumah tangga. Lumpur aktif adalah salah satu teknologi konvensional yang umum digunakan di Indonesia. Tujuan penelitian ini adalah untuk mengetahui proses degradasi bahan organik dan pertumbuhan mikroorganisme konsorsium dalam reaktor pengolahan sequencing batch reactors (SBR) anoksik. Proses pengolahan dibagi menjadi 4 tahap yaitu aklimatisasi tahap 1, 2 dan 3 serta proses pengolahan. Nilai oksigen terlarut (DO) tetap dijaga agar tetap berada dalam rentang 0,1-1 mg/L agar berada dalam suasana anoksik. Aklimatisasi tahap 1, 2 dan 3 berhasil menyisihkan COD 94,3%; 66,7% dan 58,1% dan pertumbuhan biomassa yang baik. Karakteristik awal air limbah olahan babi memiliki nilai BOD5/COD sebesar 0,52 sehingga proses biologis dapat diaplikasikan. Nilai C/N dalam air limbah hanya 0,86. Proses pengolahan air limbah oalahan babi dilakukan dalam waktu 12 hari. Penyisihan COD dalam waktu 12 hari sebesar 54,5% sedangkan penyisihan total kjeldahl nitrogen (TKN) sebesar 73,32%. Pertumbuhan biomassa pada hari terakhir pengolahan 1,284 g/L. Nilai pH dalam proses pengolahan tidak berubah secara signifikan.Pork production in Indonesia is increasing with demand and markets. The result of this activity is piggery wastewater containing organic matter and very high fat is difficult to treat. Easy and inexpensive wastewater treatment needs to be applied, considering that home industries most dominate this business. Activated sludge is one of the conventional technologie applied in Indonesia. The objective of this study was to determine the degradation process of organic matter and the growth of consortium microorganisms in anoxic sequencing batch reactor (SBR). The processing process is divided into 4 stages, acclimatization of stages 1, 2, 3 and piggery wastewater treatment. Dissolved oxygen (DO) values are maintained to the range of 0.1-1 mg/L to be in an anoxic condition. Acclimatization 1, 2 and 3 successfully remove COD 94.3%; 66.7% and 58.1% and good biomass growth. The initial characteristics of piggery wastewater having a BOD5/COD value of 0.52 can be applied in biological process. The C/N value is only 0.86. The process of piggery wastewater treatment is carried out within 12 days. Removal of COD within 12 days was 54.5% while Removal fof TKN was 73.32%. Biomass growth on the last day of processing 1,284 g/L. The pH value did not change significantly.

Microalgae biomass production is recognized as a costeffective and sustainable alternative to currently used approaches to tertiary wastewater treatment. However, such limitations, as algae biomass separation from water, process efficiency in cold climate and the algae biomass ability to reduce micropollutant content in wastewater hamper this method from full-scale use. This review discusses the identified drawbacks and offers possible improvements and modifications for wastewater phycobioremediation.

Abstract. Eutrophication-promoting phosphorous loads originating from wastewater treatment plants are commonly controlled by chemical precipitation in the tertiary treatment phase. However, this approach is costly and generates additional waste. Therefore, inexpensive and sustainable methods for wastewater post-treatment are wanted. The artificial aquatic food-web that performs wastewater phycoremediation by algae and subsequent biomass harvest by filter-feeding organisms not only requires low energy consumption but also produces biomass for treatment process cost recovery. Still, the knowledge on its performance at different scales and under different climates are limited. In this review, the application possibilities of the artificial aquatic food-web for domestic wastewater post-treatment is discussed, focusing on its use in cold climate regions. Considering the reduced biological activity of aquatic organisms at low ambient temperature, possible solutions for its performance and prospect application at low temperatures are suggested. Finally, directions for future research regarding the practical use of artificial aquatic food-web are highlighted.
