Dissolved organic nitrogen (DON) derived from wastewater effluent can participate in reactions that lead to formation of nitrogenous chlorination by-products, membrane fouling, eutrophication, and nitrification issues, so management of DON is important for both wastewater reuse applications and nutrient-sensitive watersheds that receive discharges from treated wastewater. This study documents D...

Oily wastewater has been recognized as a threat to the environment due its hazardous nature and it can negatively affect ecosystem, threaten wildlife human health. Physical, chemical, biological technologies demonstrated mixed performance in oily treatment, and, therefore, proper treatment technology for needs be addressed. Membrane filtration using hollow fiber (HF) membrane is promising alter...

Submerged membrane bioreactors (MBRs) have been gaining in popularity in various types of wastewater treatment. One drawback of submerged MBRs is the difficulty in removing nitrogen because intensive aeration is usually carried out in the tank and the MBRs must therefore be operated under aerobic condition. In this paper, feasibility of a baffled MBR (BMBR), treating municipal wastewater partic...

In this study we evaluated the performance of forward osmosis (FO) at the pilot scale to achieve simultaneous seawater desalination and wastewater reclamation. The investigation was performed with a commercial spiral wound FO membrane element for approximately 1300 h of continuous operation, processing 900,000 L of wastewater effluent and producing 10,000 L of purified water through a hybrid FO...

The presence of heavy metal ions in polluted wastewater represents a serious threat to human health, making proper disposal extremely important. utilization nanofiltration (NF) membranes has emerged as one the most effective methods ion removal from due their efficient operation, adaptable design, and affordability. NF created advanced materials are becoming increasingly popular ability depollu...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...

In this study, effect of antiscalant usage on minimizing of membrane fouling due to high water hardness during wastewater treatment tests run by a pilot-scale membrane bioreactor (MBR) system. The membranes used in these studies were Kubota flat sheet MBR membranes made from polyethylene with a pore size of 0.4 micrometer. Preliminary tests were carried out with tap water...

Abstract The harmonious coexistence of humans and nature has reached a broad consensus in the world. Maintaining health ecological environment is foundation existence development human civilization, also inevitable choice for beings to deal with global crisis. As an important factor affecting stability, rural domestic wastewater been neglected not treated effectively long time because its speci...
