Low Strength

The study aims to investigate an appropriate wastewater treatment process to treat domestic wastewater in Hanoi City which contain low-strength for COD (120-200 mg/L) but high in nitrogen content (10-40 mg/L). A lab scale anoxic-oxic system with a hollow fiber-Membrane Separation Bioreactor was operated at a flow rate of 5-10 L/h over a period of 150 days. The reactor was operated at different sludge recirculation rates. The MBR maintained relatively constant transmembrane pressure. During 150 days of reactor operation, treated water quality have COD of around 20 mg/L, NH4-N of less than 1 mg/L, NO3-N of less than 5 mg/L. The system shows good and stable efficiency for organic matter and nitrogen removal without adding an external carbon source and coagulants. The results based on the study indicated that the proposed process configuration has potential to treat the low-strength wastewater in Hanoi.

Chúng tôi đã nghiên cứu và vận hành chạy thửmô hình xửlý sinh học yếm khí-kỵkhí (AO) kết hợp với màng vi lọc ởquy mô mô hình phòng thí nghiệm (công suất 5-10 L/h) ởcác chếđộcông suất bùn tuần hoàn khác nhau. Kết quảxửlý trong thời gian 5tháng vận hành mô hình cho thấy chất lượng nước thải sau xửlý có hàm lượng COD nhỏhơn 20 mg/L, NH4-N nhỏhơn 1 mg/L, NO3-N nhỏhơn 5 mg/L. Hiệu suất xửlý chất hữu cơ và chất dinh dưỡng rất ổn định và hệthống không phải sửdụng các nguồn bổsung chất hữu cơ hay các hóa chất trợlắng như các công nghệđang áp dụng. Kết quảcho thấy công nghệAO kết hợp màng vi lọc có khảnăng áp dụng thực tế,phù hợp với những nơi có quỹđất nhỏ, chất lượng nước sau xửlý rất cao có thểphục vụcho mục đích tái sửdụng.

Domestic Wastewater Treatment

Domestic wastewater from non toilets is referred to as grey wastewater, domestic wastewater from bathing, washing and from the kitchen. Incubator Bisnis (INBIS) Permata Bunda is a forum for the application of entrepreneurial skills (apprenticeship) for people with disabilities residing in Kampung Aren, Bontang City, East Kalimantan. Grey wastewater treatment at INBIS Permata Bunda with a grease trap, filtration, sedimentation, anaerobic biofilter, aerobic biofilter, sedimentation and control. The research objective was to determine the effectiveness of INBIS Domestic WWTP to reduce organic pollutant loads based on the quality standard parameters of domestic wastewater from the Minister of Environment and Forestry Regulation No.P.68 of 2016 those are the parameters of pH, BOD, COD, TSS, fatty oil, ammonia, and total coliform. The domestic wastewater treatment process for grey wastewater has a reduced effectiveness ranging from 56.73% - 97.65% and has met the quality standards for the parameters, pH, BOD, COD, ammonia, fatty oil, and total coliform, but for TSS parameters and total coliform needs operational evaluation. Grey waterwater from the INBIS domestic wastewater treatment plant has the potential to become an alternative water source for watering plants (afforestation) if the processing results are in accordance with quality standards.

Balance Analysis

This paper provides feasibility estimation for actual domestic wastewater treatment under assumptions of a flow of 10,000 m3/d (about 40,000 capita), when air cathode MFCs configurations were adopted. Temperature-phased (mesophilic-ambient) process configurations in which can achieve either better effluent quality (i.e. maximizing treatment) or high energy recoveries is schematized. The performance used in the mass balance analysis of the treatment process conducted here compared with typical values in conventional biological wastewater treatment. Various advantages of using MFCs for wastewater treatment, including energy saving, less sludge production (and perhaps the lack of a need for a secondary clarifier), and no need for sludge handling, etc., were also addressed.

Over a 12 month period F-specific bacteriophages, faecal coliforms and enterococci were compared as microbial indicator organisms for the quality of a wastewater treatment (oxidation pond) system. Results suggest that enterococci may be the most useful indicator for oxidation pond systems.
