Glass Recycling Factory - Case Study

by AMCON Inc.  (Jul. 28, 2014)

Adjusting the specification according to the dewatering target. This factory recycles glass and processes them into small pieces which can be used for making glass bottles. Nevertheless, the pieces of glass need to be washed before having been shipped to another factory where the final product will be made and this cleaning water needs to be ...

Caustic Recovery Using Membrane Filtration

by GEA Filtration  (Mar. 19, 2009)

Abstract Food and beverage processors that use dilute caustic solutions for cleaning process equipment have shown increased interest in recovering the used caustic. The primary reason is that the price of caustic has increased significantly in the past year or so. Membrane filtration technology can be used to remove suspended solids (clarify with ...

SANASA Capivari II – the first full-scale municipal membrane bioreactor in Latin America

by IWA Publishing  (Jul. 23, 2014)

The macro region of Campinas (Brazil) is rapidly evolving with new housing developments and industries, creating the challenge of finding new ways to treat wastewater to a quality that can be reused in order to overcome water scarcity problems. To address this challenge, SANASA (a publicly owned water and wastewater concessionaire from Campinas) ...

Case study - Mining equipment cleaned with Ivey-sol prior to painting. used to remove residual oils and coal dust. successful application

by Ivey International Inc.  (Jul. 10, 2014)

It was excellent, it worked very well It took all the oils and coal residues off in a fraction of the time it normally takes when using just high pressure hot water. It allowed us to clean and prep the equipment for painting in 1 verses 2 days". Post Treatment Water Following Ivey-sol Treatment of Heavy Waste-oil Contaminated Soils at a Refinery ...

Assessment of manganese removal from over 100 groundwater treatment plants

by IWA Publishing  (Jun. 25, 2014)

The aim of this study was to make an inventory of water quality and operational parameters which could affect manganese removal through aeration and rapid sand filtration and to establish correlations between these parameters and manganese removal efficiency. The focus of the overview was on manganese removal efficiency in the first ...

Forward osmosis for the treatment of reverse osmosis concentrate from water reclamation: process performance and fouling control

by IWA Publishing  (Jun. 25, 2014)

While high quality water reuse based on dual membrane filtration (membrane filtration or ultrafiltration, followed by reverse osmosis) is expected to be progressively applied, treatment and sustainable management of the produced reverse osmosis concentrate (ROC) are still important issues. Forward osmosis (FO) is a promising technology for ...

AVA is a leading supplier of machines and system solutions with main competence in mixing and drying, across all industry sectors. An important field of AVA business is the development and delivery of turnkey (mobile) plants for the treatment of contaminated recyclable fractions and waste under high vacuum and/ or high temperature.  The ...

Ceramic water filters impregnated with silver nanoparticles as a point-of-use water-treatment intervention for HIV-positive individuals in Limpopo Province, South Africa: a pilot study of technological performance and human health benefits

by IWA Publishing  (Jun. 18, 2014)

Waterborne pathogens present a significant threat to people living with the human immunodeficiency virus (PLWH). This study presents a randomized, controlled trial that evaluates whether a household-level ceramic water filter (CWF) intervention can improve drinking water quality and decrease days of diarrhea in PLWH in rural South Africa. ...

Removal of arsenic from contaminated groundwater with application of iron electrodissolution, aeration and sand filtration

by IWA Publishing  (Jun. 12, 2014)

The results from a new water treatment system for arsenic removal are presented. The technology is based on the employment of an electrolytic iron dissolution and efficient aeration procedure prior to sand filtration. The treatment was introduced and investigated in a pilot scale plant and full scale waterworks. The pilot scale results showed the ...

Use of flocculants for increasing permeate flux in anaerobic membrane bioreactors

by IWA Publishing  (Jun. 5, 2014)

Biomass retention, required for high rate anaerobic wastewater treatment, can be accomplished coupling an anaerobic bioreactor with membrane filtration. However, low flux seems to be a common factor when operating anaerobic membrane bioreactors (AnMBRs). Modification of biomass properties may represent a strategy for improving membrane flux. The ...
