Abstract. The application of membrane technology in water and wastewater treatment is increasing due to stringent water quality standards. Nanofiltration (NF) is one of the widely used membrane processes for water and wastewater treatment in addition to other applications such as desalination. NF has replaced reverse osmosis (RO) membranes in many applications due to lower energy consumption and higher flux rates. This paper briefly reviews the application of NF for water and wastewater treatment including fundamentals, mechanisms, fouling challenges and their controls.

Scioto River

<i>Abstract</i>.—A 37-year series of standardized fish assessments in the Scioto River (Ohio, USA) since 1979 coupled with historical information documents a near complete recovery from heavily polluted conditions in the late 19th and early to mid-20th centuries. Nearly 100 fish species were extirpated downstream from the city of Columbus (Ohio, USA) by sewage and industrial pollution. The 1972 amendments to the Federal Water Pollution Control Act (Clean Water Act) mandated the control of sewage and industrial pollution. Reductions in loadings of untreated or poorly treated sewage were incremental. Full recovery to near-prepollution composition and abundance took more than two decades after advanced wastewater treatment was achieved. Unpolluted tributaries served as recolonization sources for populations of extirpated species. These positive changes extended across all fish assemblage members as evidenced by increased values of the Ohio index of biotic integrity; modified index of well-being; native species richness, density, and biomass; and the reduced incidence of external anomalies on fish. These restoration successes and their documentation were facilitated by the Clean Water Act that set forth the goals for water quality standards and treatment technology for reducing water pollution and conducting baseline and follow-up monitoring. An important lesson learned was that serious doubts that existed in the 1970s about the feasibility of advanced wastewater treatment technology and the attainability of water quality standards in an effluent dominated river were completely erased by the demonstrated improvements in the fish and macroinvertebrate assemblages in the Scioto River. The extent of improvements in recreational opportunities have tracked that of the biota by an increased use for fishing, canoeing, kayaking, and related forms of recreation. However, maintaining these improvements will require continuation of high levels of wastewater treatment and water quality standards. A growing human population that is forecast to increase by one-half million persons by 2050 makes maintaining the currently high levels of biological integrity a continuing challenge. Given the lessons learned with the mosaic of stressors in the Scioto River over the past 150 years, we believe this challenge can be met successfully.

ABSTRAKAir limbah Rumah Potong Hewan (RPH) yang tidak dikelola dengan baik dapat menimbulkan masalah lingkungan dan gangguan pada masyarakat yang bertempat tinggal di sekitar RPH. Sejak RPH X beroperasi pada tahun 2009, pengelolaan air limbah RPH X masih belum berjalan optimal. Hal ini dikarenakan air limbah RPH X masih dilihat sebagai materi yang tidak berguna dan dibuang. Saat ini, praktik pengelolaan air limbah RPH X dilakukan dengan menggabungkan semua air limbah kemudian air limbah tersebut diolah dengan Instalasi Pengolahan Air Limbah (IPAL). Riset ini mencoba menganalisis praktik pemotongan sapi, fasilitas RPH, pengelolaan air limbah RPH, kualitas air limbah RPH, dan dampak limbah RPH pada masyarakat. Riset ini menggunakan pendekatan metode kuantitatif dan kualitatif, melalui observasi, wawancara, kuesioner, dan uji laboratorium. Hasil riset menunjukkan bahwa praktik pemotongan sapi di RPH X termasuk kategori baik, fasilitas RPH X termasuk kategori kurang sesuai dengan persyaratan, pengelolaan air limbah RPH X belum berjalan optimal, kualitas air outlet IPAL telah memenuhi baku mutu, dan dampak limbah RPH X pada masyarakat berupa gangguan bau yang dirasakan oleh 100% responden dan gangguan kesehatan berupa mual yang dirasakan oleh 41% responden. Alternatif peningkatan dalam pengelolaan air limbah RPH yang dapat dilakukan adalah minimisasi air limbah melalui segregasi dan pemanfaatan air limbah RPH.Kata kunci:    Rumah Potong Hewan, praktik pemotongan sapi, fasilitas RPH, pengelolaan air limbah RPH, kualitas air limbah RPH, dampak limbah RPH, minimisasiABSTRACTWastewater of slaughterhouse is not managed optimally can cause environmental problems and disruption to communities living around the slaughterhouse. Since slaughterhouse X operates in 2009, wastewater management of the slaughterhouse X is not managed optimally. This is because the wastewater of the slaughterhouse X is seen as useless and discarded material. Currently, the wastewater management of the slaughterhouse X is carried out by mixing all of the wastewater and then the wastewater is treated by Wastewater Treatment Plant (WWTP). This study analyzes practice of cattle slaughtering, slaughterhouse facilities, wastewater management, wastewater quality, impact of slaughterhouse waste. This study exercises quantitative and qualitative methods, through observations, interviews, questionnaires, and laboratory test. The results showed that the practice of cattle slaughtering was categorized into good, the slaughterhouse X facilities were categorized into less suitable, the wastewater management of slaughterhouse X is still not managed optimally, the wastewater quality of WWTP outlet is comply with water quality standards, and the impact of slaughterhouse waste to the communities living around the slaughterhouse is odor disruption felt by 100% of respondents and health issue are nauseous felt by 41% of respondents. An alternative to improving wastewater management of slaughterhouse is minimization through segregation and utilization of slaughterhouse wastewater.

Abstract. Harsh environment, severe aridity, and climate change create chronic water shortages in the Middle East. Technical challenges, socio-economic factors, and competing uses of water have escalated the difficulties in water planning at national and institutional levels. This research identifies opportunities and challenges associated with wastewater treatment systems and the potential for wastewater reuse in the West Bank, Tunisia, and Qatar through the following objectives: (1) identify the factors associated with successful and unsuccessful reuse schemes, (2) compare treated wastewater quality with end use application of treated wastewater, and (3) identify the governance and social challenges preventing the use of treated wastewater, specifically in agricultural applications. Water quality analyses and consultations with farmers, local stakeholders, and water and agriculture experts were conducted. Opportunities and challenges for treated wastewater reuse in agriculture are identified as the proximity of the treatment facility to agricultural areas, water quality, and motivation of farmers. With proper maintenance and appropriate monitoring, the modest (natural) treatment facilities in the West Bank and secondary treatment technologies in Tunisia are capable of producing effluent safe for use in production of certain agricultural products; however, in Qatar, despite massive investments in producing high-quality treated wastewater using advanced treatment technologies, there is little demand. Water policies, laws and acts, and action plans are urgently needed to be coupled and integrated for implementation. Keywords: Arid lands, Food security, MENA, Wastewater treatment, Water reuse.

Access To Water

The issues of wastewater treatment and the reuse of water are of great importance, especially in areas where the shortage of conventional resources is a structural problem, as it is in the case of Spain. Wastewater reuse is a valid mechanism to avoid problems derived from droughts and water scarcity. It allows access to water resources in areas with water restrictions and to prevent futures scenarios, due to it being expected that water consumption will double by 2050 over the world. Thus, the likelihood that this unconventional, strategic resource would become scarce is unquestionable, particularly in cases where water planning and exploitation systems prioritize the preservation, protection, and improvement of water quality, as well as the sustainable and efficient use of natural resources. This paper shows how wastewater treatment and reuse are linked, as the reuse of wastewater is associated with a previous regeneration, and both of them are essential tools for maximizing environmental outcomes, as called for in the European Union Directives.
