The plant consists of a rotary drum influent screen, flow equalization, USBF® bioreactors, microfiltration for effluent polishing and UV disinfection. The facility also pre-thickens sludge prior to sending it to drying beds. ...
Both PureBlue StratoFlux++ and Lazur++ are fully utilised here during the effluent polishing stage. The installation is made up of a concrete basin and two containers coupled to each other. ...

Compliance with the consent values compelled the water authorities to implement moving bed biofilters (MBFs) for tertiary stage effluent polishing. However, on-site and field surveys reveal that numerous MBF units suffer from non-optimal operational conditions, logistical challenges and irregular monitoring. ...
Due to the necessary capacity increase, the effluent for the upgraded plant was required to meet a more stringent quality than the existing facility. ...
While stormwater will pass through a patented Actiflo® ballasted flocculation system, the wastewater train involves the removal of suspended solids using Multiflo™ lamella settlers, followed by Hybas™ (a combination of activated sludge and AnoxKaldnes’ MBBR technology), before the effluent is polished using proprietary Hydrotech™ ...
Problem The three-cell lagoon system at the City of DeSoto, Iowa, consistently met its permit until new effluent limits on ammonia required an upgrade. The city needed to nitrify efficiently in winter without the prohibitive expense and disruption of replacing the lagoon system. ...
“Knowing the instantaneous final effluent quality, we can immediately take corrective process measures to improve process performance and final effluent ...
Cervecería Centro Americana (CCA), a brewery located in Guatemala, is enhancing its environmental performance by using Global Water & Energy (GWE) technologies to convert the organic matter of the wastewater into biogas while achieving effluent quality improvements of 97% in organic matter removal. The brewery based in Guatemala City will treat its wastewater with a ...
Higher COD removal. Suitable for all industry effluent. High Biogas production. Double polishing system to achieve lower organic pollutant in effluent. ...
A life cycle assessment (LCA) approach was used in the assessment of environmental impacts of some polishing units for reuse of wastewater treatment plant effluents in agricultural irrigation. These alternative polishing units were assessed: (1) microfiltration and ultraviolet (UV) disinfection, (2) cartridge filter and ultrafiltration (UF), ...
A pilot unit including a microsieve with 10 μm mesh size was operated continuously with secondary effluent from Ruhleben wastewater treatment plant in Berlin. By applying a pretreatment of 0.07–0.09 mmol/L (as metal) coagulant and 1.5–2 mg/L cationic polymer, total phosphorus values below 80 μg/L were achieved. Coagulation with polyaluminum chloride (PACl) produced a better ...
This work evaluates the use of native microalgae consortia for a dual role: polishing treatment of municipal wastewater effluents and microalgae biomass feedstock potential for biodiesel or biofertilizer production. An initial screening was undertaken to test N and P removal from secondary effluents and biomass production by 12 consortia. A ...
The Client benefitted from: The GEM System Best flotation system – able to remove all non-dissolved materials Great Dissolved Oxygen level left on the stream (0.9 – 8.0) Extremely Effective on High TSS and FOG Streams Expandable in terms of loadings and flow Reduced Sludge Hauling Costs due to Drier, Denser Sludge Decreased Use of Chemicals Anaerobic Bioreactor (UASB) ...
After pre-treatment by the tannery that included batch-coagulation and sedimentation, the wastewater was treated by dissolved air flotation, a membrane bioreactor (MBR) and granular activated carbon (GAC) for polishing the MBR effluent. The average removal efficiency for organic substances in the MBR was 81% while total nitrogen could only be removed by 36%. ...
The MBR was applied to the treatment of raw sewage in a central treatment plant of the Bangkok Metropolitan area. The MF membrane was used for polishing the effluent of the treatment plant. The results show the quality of treated water from MBR and tertiary MF treatment could meet stringent water reuse quality standard in terms of biochemical oxygen demand, ...
The 4,000 PE (700 m3/d) wastewater treatment plant at Balf, Hungary was based on sequencing batch reactor technology with phosphorus precipitation as the tertiary step. Its effluent met quality thresholds on average, with above-threshold peaks mainly in winter. The HYDRUS/CW2D model package (PC Progress s.r.o.) was used to simulate the treatment performance of a horizontal flow ...
The experiments were carried out in a full-scale system in the city of Belo Horizonte, Brazil, with two parallel horizontal subsurface-flow constructed wetland units (one planted with Typha latifolia and one unplanted) treating the effluent from a system composed of an upflow anaerobic sludge blanket reactor and a trickling filter (TF). ...
In this descriptive-analytical study, nitrogenous and algal oxygen demand were assessed for effluent from a system of facultative partially mixed lagoons followed by the polishing pond using 120 grab samples over 1 year. Filtered and non-filtered samples of polishing pond effluent were tested in the presence and absence of a ...
Wastewater treatment plant (WWTP) effluents are considered to be a major source for the release in the aquatic environment of endocrine-disrupting compounds (EDCs). Ozone has proved to be a suitable solution for polishing secondary domestic effluents. In this work, the performance of a full-scale ozonation plant was investigated in order to ...
Final Dredge Effluent Polishing with CESF Treatment using ChitoVan Chitosan Lactate Hosting over 400 different species of plant, bird, fish, reptiles and amphibians, Burnaby Lake is the most ecologically valuable resources in the Vancouver, BC area. ...
