Urban sanitation remained a difficult problem to overcome, particularly waste watermanagement. Improper wastewater discharges that do not meet health and environmentalrequirements maybe harmful to health. In order to control discharges of domestic wastewater,the Governor of East Java issued Regulation No. 72 of 2013 regarding Wastewater Standard forIndustries and/or Other BusinessActivities that includes parameters such as pH, BOD,COD,TSS,Oils and Fats. The purpose of the present study was to determine the system and processesofcommunal WWTP in RT 4 RW 11 on Jalan Kertajaya IV Raya Kelurahan Kertajaya KecamatanGubeng of Surabaya Municipality.This was a descriptive and cross-sectionalstudy. Data were collected through observations,measurements, interviews, laboratory tests, as well as secondary data collection. Water sampleswere taken three times at the inlet and outlet of the WWTP. The collected data weresubsequently analyzed in descriptive manner.Results showed that the inflow was greater than the outflow, leading to overflow of theWWTP. Sources of wastewater conslsted of domestic wastewater, water used to wash utilities,water discharge from motor vehides washing activities. Wastewater was treated by biologicalmethod consisted of an anaerobic system and physical methods involving a filtration system.Wastewater was sampled at the inlet and outlet points of the WWTP using a time-combinationmethod. BOD removal efficiency was found to be 29.9%-67.9%; COD removal efficiency was8.5%-44.6%; TSS removal efficiency was 41.7%-92.3%; Oil and Fat removal efficiency was 5%-61.9%. The quality of treated domestic wastewater of RW 11 Kelurahan Kertajaya did not meetthe deSignated requirements with regard to parameters of BOD,COD,Oil and Fat.It is recomended to improve the processing capacity of the WWTP in order to preventoverflows, increase the dimension of the biological treatment facility, and add a grease trap unitto help the effluent quality to meet the standards stated in EastJava Governor Regulation No. 72of 2013

The background to and the rationale for the Guidelines for Municipal Type Wastewater Discharges in the Northwest Territories is discussed. Particu1ar attention is given to the development of Table 2.1, Effluent Quality of Municipal Wastewater Discharges, which was based upon expected lagoon performance. Also included is a discussion of the flow ratio and dilution ratio concepts. The viability of these concepts was assessed against the available data. It appears that the guidelines misjudged both the number of coliform bacteria in northern raw sewage and the removal efficiency for these organisms in lagoons. It appears unlikely that lagoons can consistently meet the guideline requirements. More information and research is necessary before a complete assessment can be performed.

Abstract. The urgency of the problem of local biological treatment of domestic wastewater from housing in non-canalized areas with improving the quality of treated wastewater to the level of requirements for discharge into fishery bodies of water is considered. The analysis of the state of local wastewater treatment is given. Existing technological schemes and methods of local sewage, which are used for sewage treatment, are considered. The results of theoretical and experimental studies of a complex of a local anaerobic-aerobic biological treatment of domestic wastewater from housing in non-canalized areas at the low-productivity plants are presented. The results of theoretical and experimental researches of complex of local anaerobic-aerobic biological purification of domestic wastewater of habitation in non-canalized areas at the low-productivity plants are given. On the basis of the analysis of work and embodiment of low-productivity plants, used in home and foreign practice of local treatment of domestic wastewater the expediency of application flowing multistage anaerobic-aerobic biological purification of domestic wastewater with use of communities of attached and free-swimming microorganisms is shown. The proposed low-productivity plant, which includes a three-stage aerobic biological treatment of anaerobically treated wastewater is described. The use of ruff fillers for the retention of hydrobionts gives the opportunity to clear salvo discharge, rapid restoration of the activity of the ruff fillers (for example, in power outages). The ruff fillers make it possible to organize an appropriate trophic chain of hydrobionts, which dramatically reduces the amount of excess biomass and the removal of suspensions in treated wastewater. Using the experiments in laboratory conditions and at real industrial treatment plant of a new design there were received parameters of work of stages of anaerobic and aerobic biological purification, the law of nitrification and denitrification processes, the law of specific speed of oxidation of organic pollution in specific conditions of anaerobic-aerobic technology; the opportunity of reception of quality of treated wastewater at the level of the requirements of the specifications for dump of drains in fishing reservoirs is proved.

A fragrance manufacturing wastewater is to be treated using a flowsheet which includes combined equalization and organics stripping, biological treatment followed by catalyzed chemical oxidation and waste sludge handling. Two biological processes were investigated for comparison. The first was a conventional extended aeration process, using a bench-scale reactor; the second was a cyclically operated activated sludge system batch reactor using a demonstration unit on-site. Operating parameters for generating an effluent quality of around 600 mg/L COD, through biological treatment, were established. It was found necessary to adjust the feed substrate concentration with a concentrated wastewater component to support microbial growth. The combined fragrance manufacturing waste stream was characterized by an initial COD of around 23000 mg/L. The treatment facility is required to meet a 300 mg/L COD, 175 mg/L BOD and 250 mg/L TSS effluent quality by the regulatory authorities. Satisfactory removal of residual COD to meet the discharge specification was obtained in bench tests using catalyzed chemical oxidants following biological treatment. The design intent of the full-scale facility is 38000 litres/day.

The lack of domestic wastewater management services in the Cibabat River Basin has resulted in the Cibabat River being a place to collect domestic wastewater. This of course can reduce water quality  as well as reduce the function of the river itself.  The Cibabat river is known to be a sub-watershed of the Citarum River with a surface   area of  1,855 km2. Activities in the Cibabat watershed  contribute  to the pollution load that  causes the water quality of the Cibabat River to decline, which of course has an impact on the decrease  in the quality of the river and increase  in the polluting  load that the river will receive. The research method uses the calculation of the pollutant  load based on Permen LH 115/2003. The data used are  secondary data from DLH Cimahi City, which  conducted a water quality analysis at three points during  three different seasons in 2019. One of the steps to overcome and control the pollution that occurs is to determine the actual pollutant load so that it can easily determine the application of effective technology  for controlling river water pollution  in the Cibabat River at theCimahi City.

ABSTRACTOne of domestic wastewater treatment in Bogor City is by using communal WWTP (Wastewater Treatment Plant) system. The communal WWTP treats domestic wastewater with an anaerobic baffled reactor configuration (ABR). This study aims to determine the effluent quality of communal WWTP so that it can be used as reference for related institutions in managing communal WWTP. The effluent from 3 communal WWTPs namely KSM Amanah, Rosella, and Cipendek Indah measured the content of TSS, COD, oil and grease, ammonia, and total coliform. The secondary data of effluent from 40 communal WWTP were obtained from Environment Agency of Bogor City. The result of the effluent analysis is compared with the Minister of Environment and Forestry Regulation No. P.68/2016 on the Quality Standard of Domestic Wastewater. The study showed that the total coliform parameter did not meet the quality standard in 3 communal WWTP locations, COD exceeded the quality standard in KSM Rosella and Cipendek Indah, and TSS above the quality standard in KSM Cipendek Indah. The communal WWTP in Bogor city has not been effective in reducing the pollutant content in domestic wastewater especially BOD and total coliform. The communal WWTP management needs to be improved in order for better effluent.Keywords: domestic waste, communal WWTP, effluent, quality standard, bogor cityABSTRAKSalah satu pengolahan air limbah domestik di Kota Bogor yaitu menggunakan sistem IPAL komunal. IPAL komunal mengolah air limbah domestik dengan konfigurasi anaerobic baffled reactor (ABR).

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.

Delhi, the most populated city in the country, is the capital of India. The huge population, urbanization and industrial processes contribute to degradation of water quality which is further aggravated by direct disposal of untreated domestic wastewater into the river Yamuna. In Delhi, the sewerage system is badly affected by improper management of the drainage system and insufficient installation of sewers in undeveloped as well as slum areas of the city which degrade the surface water quality of Yamuna River and create unhygienic conditions for the increasing population. In this study, three sewage treatment plants (STPs) have been selected which are situated at Najafgarh, Delhi Gate and Shahdara based on different technologies like Extended Aeration (EA), Biological Filtration and Oxygenated Reactor (BIOFOR) and Phytorid in order to assess the quality of wastewater before and after treatment and determining the removal efficiencies of various parameters. The study reveals that the performance of Delhi Gate and Shahdara STPs based on BIOFOR and Phytorid technologies are more efficient for the treatment of the municipal wastewater which can be further be safely disposed off into surface water and can be used for non-domestic purposes like irrigation, agriculture, cleaning of parks and streets. The effluent quality of Najafgarh STP based on EA technology is found to be less efficient as compared to the BIOFOR and Phytorid technologies. Hence, it is required to be operated and maintained properly with close supervision so as to achieve effluent quality standards as prescribed by the Indian standards

Decentralized Wastewater Treatment

Membrane bioreactor (MBR) package systems are providing affordable and simple-to-use decentralized wastewater treatment solutions for small to medium sized communities that face the challenge of balancing environmental and regulatory responsibilities with budgetary limitations. With a greater confidence and understanding of MBR technology, there is an increasing incentive in using MBR technology for these types of applications. Furthermore, valued qualities such as compact footprint, quick installation and start-up, process reliability, ease of operation, and superior effluent quality suitable for direct surface discharge and water reclamation have made MBR package system a preferred solution for decentralized wastewater treatment applications. This paper presents a retrofit solution for the Whitehouse Terrace Wastewater Treatment Plant. The existing extended aeration activated sludge package plant was retrofitted with a pre-engineered newterra MicroClearTM MBR package system for a small community along St Lawrence River in Brockville, Ontario. Five years full scale operation data of the MBR package system is presented and it is evident that the MBR package system consistently delivered high quality effluent that is far better than the required limit for direct surface water discharge to the St. Lawrence's river, with average effluent quality of 2.4, 2.6, 0.5, 0.05 mg/L, 1.7 counts/100 mL and 7.4 for biochemical oxygen demand, TSS, TP, TAN, Escherichia coli and pH, respectively.

In accordance with the development of tourism, sea pollution has become the major problem of the coastal zones. In order to realize sustainable touristic activities in Turkey, it is very important to treat wastewater and preserve the environmental quality. It is roughly estimated that there are around 2000 small treatment plants in Turkey. However, it is necessary to construct 10,000 more wastewater treatment plants to solve the wastewater problems in small settlements. In this study, performances of small treatment systems were investigated. Two types of the treatment plants were of concern. The first one is a continuous system based on fixed bed activated sludge process, whereas the second system is based on batch activated sludge process. 96 treatment plants have been investigated in this study. The wastewater characteristic is determined as strong domestic wastewater. It has been observed that the effluent quality of the batch activated sludge and aerated biofilter systems meet the discharge requirements of Water Pollution Control Regulation in Turkey. Furthermore, they would be easily adapted to meet the stringent standards that are proposed for sensitive zones.
