High-speed filtration using highly porous fiber media for advanced and compact particle removal

by IWA Publishing  (Oct. 16, 2014)

Since its recent introduction to the filtration industry, one of the major concerns about the use of fiber in water treatment has been its applicability for high-rate filtration while minimizing the build-up of headloss. In this study, a compact, modular filter employing non-woven, highly porous polypropylene fiber as filter media was ...

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 ...

Hong Kong Hospital Authority selects IQAir filtration systems for the fight against SARS

by Commercial Air Filtration  (Aug. 28, 2014)

In February of 2003, newspapers began reporting a rapidly spreading atypical pneumonia. Now identified as severe acute respiratory syndrome or SARS, this highly contagious condition is caused by a new coronavirus for which there is no specific antiviral treatment. While the epicentre of the outbreak was China, the disease spread quickly across ...

Industrial Nordfjord Kjott, Norway case study

Project Name: Nordfjord Kjott R.A. Location: Stryn, Norway Type of Plant: Industrial Meat Processing/Slaughterhouse Technology Used: Biowater CMFF Biofilm system Biomedia Used: Biowater BWT-X Operational Since: Summer 2011 The Challenge Located deep in the ...

Deposit membrane fouling: influence of specific cake layer resistance and tangential shear stresses

by IWA Publishing  (Jul. 16, 2014)

Cake fouling is the leading cause of membrane permeability decrease when filtering mixed liquor suspension containing high suspended solid concentrations. A simple model is proposed to simulate the cake resistance evolution with time by considering a macro-scale fouling linked only to the accumulation of particles on the membrane surface. This ...

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) ...

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 ...

Why Oil Filtration is Important for OEMs

by Chongqing Zhongneng Oil Purifier Co., Ltd.  (Apr. 28, 2014)

The need of oil filtration prevails in a number of industrial spheres which involves the usage of mechanical equipments. The types of filtration can be divided into two major categories i.e. primary filtration which is used for screening and secondary filtration used for cleaning purposes. The former is applicable and beneficial for the protection ...

Industrial Benefits of Oil Filtration and Cleaning Machinery

by Chongqing Zhongneng Oil Purifier Co., Ltd.  (Apr. 17, 2014)

It is highly recommended to keep the machinery oil clean to maintain an optimum level of operational efficiency at the production or manufacturing plants of widespread industrial spheres that depend on the usage of mechanical equipments. By doing so, the plant managers can obtain the extension and longevity in the lifetime of their site machinery. ...

Long-term studies on hybrid ceramic microfiltration for treatment of surface water containing high dissolved organic matter

by IWA Publishing  (Apr. 14, 2014)

This long-term pilot-scale study on the performance of ceramic microfiltration (CMF) was conducted at the Bangkhen water treatment plant (BWTP), with the raw water from Chaophraya River, Thailand. Raw water turbidity and dissolved organic carbon (DOC) were varied in the ranges of 20–210 NTU and 3.0–8.5 mg/L respectively. The hybrid ...
