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 ...

A novel electrospun polyurethane nanofibre membrane – production parameters and suitability for wastewater (WW) treatment

by IWA Publishing  (Apr. 10, 2014)

The aim of this study was to investigate the suitability of a novel electrospun polyurethane nanofibre material for water-treatment purposes. Bacterial removal efficiency was tested in the laboratory by filtering artificial water spiked with Escherichia coli through a 0.25 µm nanofibre membrane. The results were compared with those ...

Household survey of installation and treatment efficiency of point-of-use water treatment systems in Hanoi, Vietnam

by IWA Publishing  (Mar. 25, 2014)

Since urban water supply is not yet available for every inhabitant in Hanoi City, numerous residents look for alternative sources such as groundwater and rainwater to compensate the supply shortage. However, in parts of Hanoi, it was reported that groundwater is polluted by various contaminants including arsenic (As) and ammonia (NH4-N). ...

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 ...

Removal of water–based filter cake and stimulation of the formation in one–step using an environmentally friendly chelating agent

by Inderscience Publishers  (Feb. 18, 2014)

Chelate solutions, GLDA (pH of 3.3 to 13) and HEDTA (pH of 4 and 7) were incompatible with α–amylase over a wide range of temperatures. GLDA (pH 3.3) and HEDTA (pH 4) can be used to remove the filter cake in one step. GLDA (20 wt% in a 200 g solution and pH of 3.3) and HEDTA (20 wt% in a 200 g solution and pH 4) had 100% removal efficiency of the ...

Comparison of aerobic granulation and anaerobic membrane bioreactor technologies for winery wastewater treatment

by IWA Publishing  (Jan. 29, 2014)

An anaerobic membrane bioreactor and aerobic granulation technologies were tested at laboratory scale to treat winery wastewater, which is characterised by a high and variable biodegradable organic load. Both technologies have already been tested for alcohol fermentation wastewaters, but there is a lack of data relating to their application to ...

Analyzing the spatial and temporal characteristics of membrane fouling

by IWA Publishing  (Dec. 13, 2013)

Fouling characteristics of crossflow flat-sheet membranes for two Nanofiltration (NF), one Ultrafiltration (UF), and one Microfiltration (MF) membranes were analyzed using 12.5 parts per million (mg/L) FeCl3 solution and 350 mg/L copper nanofluid. FeCl3 solution represents dissolved contaminant whereas copper nanofluid simulates particulate ...

Facile fouling resistant surface modification of microfiltration cellulose acetate membranes by using amino acid l-DOPA

by IWA Publishing  (Aug. 29, 2013)

A major obstacle in the widespread application of microfiltration membranes in the wet separation processes such as wastewater treatment is the decline of permeates flux as a result of fouling. This study reports on the surface modification of cellulose acetate (CA) microfiltration membrane with amino acid l-3,4-dihydroxy-phenylalanine (l-DOPA) ...

Energy efficiency in membrane bioreactors

by IWA Publishing  (Jun. 21, 2013)

Energy consumption remains the key factor for the optimisation of the performance of membrane bioreactors (MBRs). This paper presents the results of the detailed energy audits of six full-scale MBRs operated by Suez Environnement in France, Spain and the USA based on on-site energy measurement and analysis of plant operation parameters and ...

Microfiltration Pilot System, California

by Pure Aqua, Inc.  (May 1, 2013)

INTRODUCTION In May 2013, Pure Aqua, Inc. successfully manufactured and supplied an microfiltration pilot system to a membrane manufacturer for Title 22 certification. Title 22 is the State of California’s stringent standard for treatment/disinfection of wastewater for non-potable reuse and ...
