In some parts of Malaysia, wastewater treatment plants (WWTPs) are located in industrial areas. These WWTPs receive wastewater mostly from these industrial activities regularly or occasionally. Therefore, their biochemical oxygen demand (BOD), chemical oxygen demand (COD) and ammonia nitrogen (NH3-N) are very high. Conventional biological treatment processes are incapable of producing desirable effluent quality with the increasingly stringent discharge requirement. In this study, a laboratory-scale membrane bioreactor (MBR) was used for treating high strength municipal wastewater. Prepared synthetic wastewater samples which represent a high strength municipal wastewater as well as the actual high strength municipal wastewater were used in the study. The developed MBR was operated under different conditions using statistical experimental full factorial design with three factors and three levels. The factors were sludge retention time (SRT), feed temperature (Tf) and organic loading rate (OLR) and ...

Enterococci are a group of commensal bacteria that are important nosocomial pathogens. They are abundant in human sewage and wastewater treatment facilities (WWTF). This study focused on the role of house flies, Musca domestica, in the ecology of enterococci at WWTF in both field and laboratory experiments. The first study objective focused on sampling and characterizing enterococci from house flies and wastewater sludge from four WWTF in northeastern Kansas. Enterococci were quantified, identified, and screened for antibiotic resistance and virulence traits, and genotyped. The profiles of enterococci (spp. diversity, antibiotic resistance and virulence) from WWTF sludge and the house flies were similar, indicating that the flies successfully acquired the bacteria from the WWTF substrate. Enterococci with the greatest amount of antibiotic resistant and virulence traits originated from the WWTF that processed meat waste from a commercial sausage plant. Genotyping of E. faecalis revealed clonal ...

The operator of a waste water treatment plant was looking for a pump with dry-run capability for his flotation system. In the flotation system, substances on the surface of the flotation tank are suctioned off using a rotating suction arm. Previously an eccentric screw pump had been used for this purpose. However, this pump had the disadvantage of needing extra water, to prevent dry running and required a lot of space and drive power. The operator then opted for a Boerger Rotary Lobe Pump. In addition to its dry-run capability, its minimum space requirements, the wide choice of material and the low drive power, the customer was also impressed with the low maintenance design of the Boerger Rotary Lobe Pump. ...

This study demonstrated the feasibility of implementing of MBR in pharmaceutical wastewater independently, and concluded different applications of MBR in industries. Membrane bioreactor (MBR) technology was a new wastewater treatment technology with a combination of membrane separation technology and biological treatment technology, which had unique advantages on pharmaceutical wastewater treatment. The modified membrane rector design provided a significantly lower concentration of NH3-N, Phosphorous, Total Nitrogen and COD around the membranes, and subsequently a more sustainable membrane performance due to much lower overall fouling rates. In this paper, the classification and structure of biological waste water treatment by using MBR technology were summed up along with some examples of MBR in industrial wastewater treatment, which was emphatically analyzed and discussed. Finally, the prospect of MBR in industrial wastewater treatment was described. The industrial wastewater was a high-strength

Birkenhead Waste Water Treatment Works is part of United Utilities Lower Mersey Project which is built in the 90s to ensure that the effluent discharges satisfy the European UWW Directive. Refurbishment of part of the plant started in late summer of 2015, which consisted of the replacement of 16 DN800 and DN900 butterfly valves which were originally installed in 2006.. Due to leakage problems and valve issues beginning 2015 constructing company Nomenca Ltd. were asked to carry out a pipeline video inspection, this revealed more substantial issues with the existing competitor butterfly valves than first thought. As seen on the images it was obvious that not only all the old valves where leaking, but for one valve the whole valve-disc had separated from the valve body and was found over 2 metres into the pipework. The pre-filtered sewage water corroded the stainless steel discs and shafts so much that it destroyed the valves completely within 10 years.. Due to the good performance of other AVK ...

In this study, three different two-stage hybrid ecological wastewater treatment systems (HEWTS) with combinations of horizontal flow (HF) constructed wetlands (CWs), vertical flow (VF) CWs and stabilization ponds (SP) were evaluated for the removal of Organic-N, NH4+, NO3−, Total N, Total P, Total Coliforms (TCol) and Escherichia Coli, BOD, COD and TSS. The overall goal of the study was novel in comparison to most other studies in that we sought to evaluate and compare the efficiency of the three HEWTSs for water quality improvements, while minimizing nutrient removal from the wastewater in order to generate high quality reclaimed water for reuse for irrigation of crops. The most effective systems were those systems containing a vertical flow component, either HF-VF or VF-HF. In these two HEWTS, NH4+ was reduced by 85.5% and 85.0% respectively, while NO3− was increased to 91.4 ± 17.6 mg/L and to 82.5 ± 17.2 mg/L, respectively, an artifact of nitrification. At the same time, E. coli was reduced by

A wastewater treatment system includes a vertical flow marsh cell that is adapted to contain media and to support plants having roots extending into the media, the roots and media positioned to contact water flowing downward through the marsh cell during a flooding stage, the media and plant roots providing surfaces to which biofilms can adsorb, the biofilms containing bacteria adapted to adsorb ammonium ions and nitrify ammonium ions to nitrate during an aerated drained phase. The marsh cell is configured to receive water from an outlet of a horizontal wetland that functions essentially anaerobically/anoxically to contain bacteria for transforming nitrate into nitrogen gas. Water to be treated and water exiting the marsh cell outlet are transportable to a wetland inlet, providing dilution of incoming wastewater. Treated water is discharged from the wetland outlet.

In Lauterbrunnen, a highly popular winter tourism resort in the Swiss Alps, the wastewater treatment plant is to be upgraded with modern and flexible membrane technology (MARAPUR® - the WABAG MBR process) in order to deal with seasonal peak loads. For the completion of this project, the local authority has turned to WABAG, which specialises in both MBR and plant modifications and enlargements in challenging circumstances. The contract was signed in September 2015. In the tourism off-season, the treatment plant handles the municipal wastewater derived from the roughly 3,000 local inhabitants. However, at peak times in winter skiing holidaymakers push the population figure up to around 12,500. Under these circumstances, the existing plant has become incapable of meeting the strict water protection requirements and is therefore about to undergo re-equipping and upgrading. WABAG is to replace the biodisc reactor technology used to date with a modern MARAPUR® membrane bioreactor system. This ...

Total nitrogen resp. the single parameters ammonium, nitrate and nitrite are important parameters to qualify wastewater. High contents of ammonium coming out the plant into a river or lake will cause a significant reduction of natural DO content by forming nitrate and nitrite. Nitrate is a nutrient which will fertilise the rivers and lakes. Nitrite is poisonous for fish and micro-organism. The value of total N at the outlet of a waste water plant or in rivers and lakes should be below 18 mg/l. For control of a nitrification/denitrification-process in a waste water treatment plant ammonia measurement is a must.. Phosphorus ...

The Company KUPFER, a meat processor in Bavaria, needed upgrading of its existing wastewater treatment plant for compliance with more stringent effluent requirements and due to increased loading. The consulting engineer selected a membrane bioreactor (MBR) system to avoid the need for huge tank volumes and to provide the future possibility of water re-use. Extensive pilot tests showed that MBRs must be designed with a holistic view as wastewater pretreatment has a strong impact on MBR performance and reliability. Solids and emulsified fats, oil, grease and colloidal matter should be sufficiently removed by fine screening and dissolved air flotation (DAF); otherwise one can expect rapid fouling of the membrane surface. Based on the satisfying results of the pilot tests the consulting engineer designed the new wastewater treatment plant. In January 2008, the MBR plant was commissioned and after a 3 months start-up period the plant shows excellent performance ...
