Treatment of landfill leachate by hybrid precipitation/microfiltration/nanofiltration process

by IWA Publishing  (Jul. 16, 2015)

This paper describes a promising method to treat stabilized landfill leachate. Such method consists of a combination of chemical precipitation processes, a cost-effective technique with high potential to remove contaminants with foulant nature, microfiltration aimed at removing the produced precipitate and nanofiltration (NF) for final ...

Confirmation of the correlation between membrane fouling in microfiltration and biopolymer concentrations in various Japanese surface waters

by IWA Publishing  (Apr. 8, 2015)

A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a ...

Cake porosity analysis using 1D–3D fractal dimensions in coagulation–microfiltration of NOM

by IWA Publishing  (Mar. 16, 2015)

Fouling during coagulation–ceramic microfiltration of natural organic matter was investigated. Two process configurations (inline coagulation (IC) and tank coagulation (TC)) and two process conditions (types of coagulants–aluminum-based PAX and iron-based PIX–and G-values) were studied. The rate of irreversible fouling ...

Membrane fouling mitigation by activated carbon addition in activated sludge filtration

by Inderscience Publishers  (Dec. 24, 2014)

Activated carbon (AC) was added into the activated sludge to alleviate membrane fouling during sludge microfiltration. The fouling mitigation profiles were evaluated at different AC sizes and doses by a single-fibre microfiltration system. It was found that the granular AC added in the sludge suspension can absorb the organic substances in the ...

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 ...

Recovery of volatile fatty acids (VFA) from complex waste effluents using membranes

by IWA Publishing  (Feb. 19, 2014)

Waste effluents from anaerobic digesters of agricultural waste were treated with a range of membranes, including microfiltration and nanofiltration (NF), to concentrate volatile fatty acids (VFA). Microfiltration was applied successfully to produce sterile, particle-free solutions with a VFA concentration of 21.08 mM of acetic acid and 15.81 mM ...
