The knowledge of the boundary flux values permits avoidance of high fouling operating conditions on a selected membrane. The goal here was to determine the framework for control of an ultrafiltration (UF) and nanofiltration (NF) batch membranes-in-series process treatment for olive mill wastewater, relying on these boundary flux points, which ...

Nitrifying bacteria in wastewaters significantly affected Chlorella growth as they possibly competed with Chlorella in assimilating ammonia and nitrate in domestic wastewater. In a submerged ultrafiltration (UF) membrane module, with an initial concentration of 850 mg/L of Chlorella, the optimized flux was 0.02 m3/(m2·h), and the ...
Fouling is still the limiting factor to run high performance and energy efficient installations. Berghof Membrane Technology produces tubular ultrafiltration membranes and modules for the use in sidestream MBR applications. The advantage of these tubular membranes with inner tube diameters ranging from 5 till 10 ...
Apart from plenty of advantages, the main disadvantage of ultrafiltration is rapid flux decay due to concentration polarisation and membrane fouling. The purpose of this work is to overcome this problem employing shear enhanced membrane filtration technique. To accomplish this, two different membrane modules were ...
A pilot-scale dual-stage membrane bioreactor (dsMBR) incorporating two ultra-filtration (UF) side-stream membrane modules was designed, constructed, operated and evaluated on-site for treating high-strength textile effluent. The effluent stream was characterised by a COD range of between 45 to 2,820 mg/L and an average BOD of 192.5 mg/L. The dsMBR achieved an average COD reduction of 75% with a ...
A review on pulp and paper industrial membrane processes using a variety of modules and processes is presented. ...
This work is a review of the study performed on heavy metals biosorption by Sphaerotilus natans confined in an ultrafiltration membrane module. A methodological approach has been applied aiming at the dynamic modelling of the process: i) firstly, biosorbent was characterised according to acid-base properties of binding sites; ii) then, ...
The VSEP system uses nanofiltration followed by ultrafiltration membrane modules and is able to treat the mine tailing pond effluent, reducing suspended and dissolved solids below the required limits for process recycling or discharge. The economics of installing this system are extremely attractive with a 35% reduced capital cost combined with a ...
The VSEP (Vibratory Shear Enhanced Processing) system uses an ultrafiltration membrane module and is able to recycle up to 80 percent of the water used at this facility. ...
The VSEP is used for treatment of river water for ultrapure water production at this facility. The VSEP system uses an ultrafiltration membrane module and is able to treat river water in order to remove or reduce color, turbidity, permanganate consumption, and total iron below the required limits. The economics of installing this system are very ...
VSEP is used for treatment of a chromate batch solution at this facility. The VSEP system uses an ultrafiltration membrane module to treat pressate from the filter press operation in order to recover pigments and also generate a permeate stream that meets the required discharge limits. The estimated construction, operation, and maintenance costs ...
Extremely high shear energy is delivered directly to the surface of the membrane eliminating the gel layer buildup while maximizing flux rates. By deriving shear from the membrane movement, V✧SEP delivers shear rates 10-15 times higher than that of conventional cross flow systems. ...
VSEP is used for preconcentration of Poly Vinyl Chloride (PVC) latex to a spray dryer at this facility. The VSEP system uses an ultrafiltration membrane module and is able to concentrate (dewater) latex emulsions from a concentration level of 38 percent to a level of 55 to 68 percent. ...
