This study demonstrated onset, acclimation, and acceleration of Mn(II) removal in a two-stage pilot-scale biofilter (Fe and Mn filters) at varying low on-site temperatures (8–14.8 °C). ...
A slightly higher microsphere removal (2.3 log) was obtained for these DE-precoated filters when the filtration rate was 3.6 m/h. Additionally, pilot-scale perlite-sand filters achieved greater than 2 log removal when at least 0.37 kg/m2 of perlite was used compared to 0.1–0.4 log removal without perlite both at a surface loading ...
The ANN model was developed and tested based on experimental data collected from a pilot scale multi-media filter system. Several ANN models were tested, and the best results with the lowest errors were achieved with two hidden layers and five neurons per layer. ...
In this study, petrochemical secondary effluent was treated by a 55 cm diameter pilot-scale biological aerated filter (BAF) with a media depth of 220 cm. ...
In order to protect public health during swimming, Cryptosporidium-sized microsphere removals by high-rate sand filtration with six coagulants were evaluated with a 5.5 m3 pilot-scale swimming pool. A sand filter without coagulation removed 20–63% of Cryptosporidium-sized microspheres. ...
Additional AC samples were obtained by sampling different depths of a full-scale AC filter at regular intervals during the operation time of the filter. Several adsorption tests were performed with the three test substances, including adsorption isotherms in the concentration range mg/L, single-point adsorption tests in the concentration range ...
This study provides additional insight into the effect of biofiltration as a pretreatment for fouling reduction by using river water with different raw water quality characteristics than has been examined in previous studies. Two parallel pilot-scale dual media (sand/anthracite) biological filters were operated continuously over a period of 14 ...
Having tested our technology, the esteemed University of Alberta is entering the AOS Filter industrial pilot-scale-testing phase, which we expect to confirm its commercial viability to treat oil sands tailings ponds and then eliminate the need for them on a go forward basis. ...
The aim of this study was to evaluate backwashing effects on the apparent porosity of the filter media and on the hydraulic behaviour of a pilot scale submerged filter, prior to biofilm colonization, under different hydraulic retention times, and different air flow rates. ...
This paper also reports the results of a laboratory and a pilot scale study with a deep bed filter (granular activated carbon, GAC) and microfiltration (MF) hollow fibre membrane filter system used to treat raw rainwater collected from a metropolitan rainwater tank. The results of the laboratory experiment and ...
Additional wastewater streams requiring treatment can be generated from other on-site sources such as scrubbing of exhaust gases from incineration and combustion, bleed from boiler feed water systems, back-washing of filters, laboratory and pilot-scale plants and collection of rainwater from contaminated areas. ...

A strain of autotrophic micro-organism, Rhodococcus sp.zw11, was isolated from pharmaceutical wastewater containing hydrogen sulphide (H2S). The shape, physiological and biochemical characteristics and oxidation capacity of Rhodococcus sp.zw11 were studied, and the effect of inlet concentration and volumetric loading of H2S on the removal efficiency was evaluated by the biotrickling filter ...
Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. ...
