Conventional methods of disinfecting sewage water are all highly sensitive to variations in the effluent quality upstream of the disinfection stage. Microfiltration was tested as a tertiary treatment downstream of biofiltration, simulating very poor biofilter efficiency, to test the limits of the microfiltration process. Despite the poor quality of the secondary effluent (COD between 100 and 400 mgO2/l, BOD5 between 30 and 150 mgO2/l and suspended solid concentrations between 15 and 90 mg/l), the microfiltration process (filtration level : 0.2 µm) eliminated all faecal germs and tenia and ascaris eggs. The total elimination of free amoeba cysts still needs to be confirmed. With the COD and BOD5 reduced by an average of 60 and 70% respectively, the effluent quality is equivalent to level e after microfiltration (COD: 90 mgO2/l and BOD5=30 mgO2/l on samples averaged over 24 hours). Turbidity, measured instead of suspended solids at outlet from the microfilter, was 99% eliminated. The colour remained between 50 and 150 mg Pt.Co/l. Under the operating conditions applied, the minimum filtration cycle was 72 hours for a minimum permeate flow of 80 l/h/m2 of membrane.

Wastewater containing oil and polyacylamide is a kind of organic wastewater, which is hard to treat. The combined process of moving-bed biofilm reactor and sulphate-reducing bacteria was used to treat the wastewater. Operating conditions of moving-bed biofilm reactor and sulphate-reducing bacteria were studied. Results indicate that the oil removal efficiency by moving-bed biofilm reactor can reach above 90% with 9 hours hydraulic retention time at 25°C, but it has no effect on polyacylamide. Sulphate-reducing bacteria can degrade polyacylamide, and polyacylamide conversion is about 50% at 37°C with 4 days culture time and 9ml inoculation size. The effluent quality of wastewater containing oil and polyacylamide can meet requirements of the first level in integrated wastewater discharge standard.

Marine life and natural scenery - in the category of nautical tourism - are the potentials of the Kelapa Lima, Kupang beach. However, there are problems that; construction progress, residentials and bussines activities nearby coast of Kelapa Lima, Kupang, indicated that there are contamination by wastewater into the waters of this beach. Then, this issue is adjusted to the standards Environment Minister Regulation number 51 of 2014 and in 2013 number 115 on the sea water quality standard. The method used is the equation written by Sumiotomo and Nerow (1970) in the Minister of Environment No. 115 of 2003. The formula that is used to calculate the results of studies measuring the location parameter with the default value determined by the Ministry of Environment in 2004. Later, research shows that the quality of the waters of the Pantai Kelapa Lima Kupang has begun to decline in the presence of contamination by sewage. Liquid waste is already affecting marine life that corals and mangroves, while the beauty of the sea coast, the liquid waste is already reducing the amount of oxygen for the oxidation process that takes coastal sea to the decomposition of waste into the sea, causing sedimentation affect water clarity sea shore. Therefore, there needs to be immediate action from the government to educate more people about the importance of maintaining the beauty of the beach, and helped make the disposal of liquid waste discharges in coastal areas to reduce the causes of liquid wastes into the coastal sea.

Tidal Area

Access to public sanitation in the tidal area in Indonesia is limited. The people in the tidal area tend to dispose of their domestic wastewater to the water body directly without treating it first. The lack of wastewater infrastructure provision in the tidal area could cause water body pollution that degrades its carrying capacity and destructs aquatic ecosystems. Eco-friendly technology could be used to treat the wastewater in the tidal area as the solution to improve water quality. In this research, the eco-friendly wastewater treatment technology was chosen to observe the effluent quality of individual scale biofilter-phytoremediation. Performance test of wastewater treatment technology was done by measuring the effluent quality. The effluent quality of the biofilter-phytoremediation system was compared to the effluent quality standard that stated in Ministry Regulation of Environment and Forestry No. P.68/Menlhk/Setjen/Kum.1/8/2016. The study showed the following results such as the average concentration of TSS was 7,63 mg/L, pH 6,70, ammonia was 1,78 mg/L, COD was 18,16 mg/L, and BOD was 9,38 mg/L. These results indicated that in general, the effluent quality of biofilter-phytoremediation system had met the above standard.

Abstract On-site wastewater treatment systems are approved by the French regulation based on the results of platform tests following the European standard NF EN 12566-3. In addition to this approval for the treatment system, at least 90% of outlet concentrations have to be below 30 mg L−1 for total suspended solids (TSS) and 35 mg L−1 for biochemical oxygen demand. The aim of this study is to evaluate the effluent quality of these treatment systems on site, i.e. under real operating conditions, and to assess their performances. Between 2011 and 2016, 1,286 treated wastewater samples were taken from 231 on-site sanitation facilities in France. Data collected are heterogeneous and a robust statistical methodology (using a generalized log-linear model) was used to study the effects of four explanatory variables (treatment systems, loading rate, aging and sampling methods) on the distribution of treated wastewater concentrations. The model calculates median outlet concentrations depending on the effects identified. Its application allowed studying and comparing the outlet median concentrations of 21 on-site sanitation systems classified into nine categories and three groups. Four treatment systems out of the 21 monitored showed TSS median outlet concentrations below 10 mg L−1 and four treatment systems have TSS medians higher than the regulatory threshold of 30 mg L−1.
