RO membrane cleaning using microbubbles at 6,800m3/day Wastewater RO Plant in UAE.

by Genesys International Limited  (Oct. 6, 2014)

It is well known that any fouling of the membrane surface has a dramatic effect on energy consumption and plant efficiency; this is particularly true for waste water RO plants due to the higher fouling rate. Such fouling can be very difficult to clean using commodity chemicals or even speciality chemicals. This paper explores the use of a novel ...

Virus removal by an in-line coagulation–ceramic microfiltration process with high-basicity polyaluminum coagulation pretreatment

by IWA Publishing  (Jun. 12, 2014)

The ability of in-line coagulation pretreatment with high-basicity polyaluminum chloride (PACl) coagulants to enhance virus removal by ceramic microfiltration (MF) was examined by comparing virus removal efficiencies from water pretreated with PACl-2.2 (basicity 2.2) and PACl-2.5 (basicity 2.5) versus alum, a synthetic aluminum chloride (AlCl3) ...

Direct pre-treatment of surface water through submerged hollow fibre ultrafiltration membranes

by IWA Publishing  (Jun. 12, 2014)

The most distinctive characteristic of the Mediterranean climate is its strong seasonality, dry summers and intense rainfall episodes concentrated in spring and autumn. This changeability is translated into a wide variability of the water resources in terms of quantity and quality. Barcelona, located in the northeast extreme of the Iberian ...

Biomass properties and permeability in an immersed hollow fibre membrane bioreactor at high sludge concentrations

by IWA Publishing  (Jun. 5, 2014)

This study aimed to investigate the influence of biomass properties and high mixed liquor suspended solids (MLSS) concentrations on membrane permeability in a pilot-scale hollow fibre membrane bioreactor treating domestic wastewater. Auxiliary molasses solution was added to maintain system operation at constant food-to-microorganisms ratio (F/M ...

Control of Welding Fume Particulates Using Cleanable Filter Media: Hexavalent Chromium

by Sentry Air Systems, Inc.  (May 21, 2014)

Herein, a Sentry Air Systems product study of hexavalent chromium particles, [Cr(VI)], is reported. Due to the popularity of extended life cleanable filter media and health concerns regarding hexavalent chromium exposure in the work place, Sentry Air Systems conducted a study of the efficacy of cleanable filter systems for the maintenance of safe ...

Clarification of rough beer in brewery industry case study

by RVF-filtration  (May 9, 2014)

Standard filtration uses diatomaceous earth (Kieselguhr) into filter-press and consists in the retention of solid particles (yeast cells, macrocolloids, suspended matter) and solutes responsible for haze. After use the disposal of Kieselguhr (after filtration) are a major difficulty due to their polluting effect. From the health perspective, the ...
