Continuous transformation of chiral pharmaceuticals in enzymatic membrane bioreactors for advanced wastewater treatment
This study demonstrates continuous enantiomeric inversion and further biotransformation of chiral profens including ibuprofen, naproxen and ketoprofen by an enzymatic membrane bioreactor (EMBR) dosed with laccase. The EMBR showed non-enantioselective transformations, with high and consistent transformation of both (R)- and (S)-ibuprofen (93 ± 6%, n= 10), but lower removals of both enantiomers ...

Reduction of organic trace compounds and fresh water consumption by recovery of advanced oxidation processes treated industrial wastewater
Ozone (O3) has been used successfully in advanced wastewater treatment in paper mills, other sectors and municipalities. To solve the water problems of regions lacking fresh water, wastewater treated by advanced oxidation processes (AOPs) can substitute fresh water in highly water-consuming industries. Results of this study have shown that paper strength properties are not impaired and ...

Application of vibration milling for advanced wastewater treatment and excess sludge reduction
As a new sludge reduction technology with a phosphorus removal mechanism, a vibration milling technology that uses iron balls have been applied to the wastewater treatment process. Three anaerobic–aerobic cyclic activated sludge processes: one without sludge disintegration; one disintegrated sludge by ozonation; and the other disintegrated sludge with the vibrating ball mill were compared. ...

Reinforced Membrane Bioreactor: Advancing Wastewater Treatment Technology
As the global population continues to expand and urbanize, the demand for clean water becomes increasingly critical. Simultaneously, industrialization and population growth result in the generation of vast amounts of wastewater, which requires efficient treatment to safeguard public health and preserve the environment. Reinforced Membrane Bioreactors (RMBRs) have become a state-of-the-art ...

Wastewater treatment facility upgrade uses combination of technologies to solve nutrient removal challenges
New regulations required the 7.5 ML/d North East River Advanced Wastewater Treatment Facility to upgrade to meet lower annual average effluent nitrogen and phosphorus limits. At the same time, facility planning was underway to expand the facility to 17.0 ML/d to accommodate planned growth in the service area. Following a pilot study to establish the performance capabilities of the existing ...

Occurrence of earthy and musty odor compounds (geosmin, 2-methylisoborneol and 2,4,6-trichloroanisole) in biologically treated wastewater
The concentrations of earthy and musty odor compounds (2-methylisoborneol (2-MIB), geosmin and 2,4,6-trichloroanisole (TCA)) in treated wastewater were measured. Concentrations of 2,4,6-TCA (4.3–37.7 ng/L) and geosmin (3.7–42.2 ng/L) higher than their odor thresholds were detected for effluents from large-scale treatment plants. The effluent from a small-scale wastewater plant ...

Compact solutions for advanced wastewater treatment aiming to recover and reuse
The environmental pollution caused from unregulated raw sewage discharge coming from small municipalities, remote communities, small housing complexes, tourist facilities, camps, factories, harbors and other similar sources that until now was difficult to construct suitable Treatment Facilities is quite extensive in many areas and is now the time for the authorities to take action. The necessity ...

Three years of operation of North America's first nutrient recovery facility
The first full-scale nutrient recovery installation in North America became operational in May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant in Tigard, Oregon. Recovering ammonia and phosphorus from the dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing the phosphorus recycle lowers the phosphorus loading on ...

Level measurement of ferric chloride case study
MonoScan provides ongoing measurement results of Ferric Chloride (FeCl3) solution in one of Israel's most advanced wastewater treatment plant. The Ashdod wastewater treatment plant has invested significantly in state-of-the-art control systems to ensure 100% usage of the wastewater entering its facilities. The plant is self sufficient, by using its own resources providing power, water and gas. ...

Reverse flexing as a physical/mechanical treatment to mitigate fouling of fine bubble diffusers
Achieving energy neutrality has shifted focus towards aeration system optimization, due to the high energy consumption of aeration processes in modern advanced wastewater treatment plants. A study on fine bubble diffuser fouling and mitigation, quantified by dynamic wet pressure (DWP), oxygen transfer efficiency and alpha was carried out in Blue Plains, Washington, DC. Four polyurethane fine ...

Investigation into cyclic utilization of carbon source in an advanced sludge reduction, inorganic solids separation, phosphorus recovery, and enhanced nutrient removal (SIPER) wastewater treatment process
An advanced wastewater treatment process (SIPER) was developed to simultaneously reduce sludge production, prevent the accumulation of inorganic solids, recover phosphorus, and enhance nutrient removal. The ability to recover organic substance from excess sludge to enhance nutrient removal (especially nitrogen) and its performance as a C-source were evaluated in this study. The chemical ...

Mini Sulfite Analyzer Continuously Monitors Dechlorination Residual
Overview UOSA Instrument Specialist Amanda Fromer uses a mini Sulfite analyzer for maintenance-free monitoring of sulfite residuals after dechlorination at a 54 MGD advanced wastewater treatment plant. Challenge The UOSA Water Reclamation Plant uses sodium hypochlorite for disinfection but is required to dechlorinate prior to discharging or reusing the wastewater. Sodium bisulfite is used for ...

Lowes Plaza commercial wastewater system information
Commercial wastewater is usually highly concentrated in organic content and complicated by sanitary routines and house keeping habits that shorten the expected life of the soil disposal system. Advanced wastewater treatment will preserve the disposal system indefinitely and often represents a one to three year return on investment for commercial facilities. This Aquapoint wastewater treatment ...

Comparative and integrative environmental assessment of advanced wastewater treatment processes based on an average removal of pharmaceuticals
Pharmaceuticals are normally barely removed by conventional wastewater treatments. Advanced technologies as a post-treatment, could prevent these pollutants reaching the environment and could be included in a centralized treatment plant or, alternatively, at the primary point source, e.g. hospitals. In this study, the environmental impacts of different options, as a function of several advanced ...

Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities
A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...
