Currently, only 41% of Cambodians have access to safe drinking water. To combat this issue, Resource Development International Cambodia (RDIC) has been promoting and developing affordable clay pot water filters to be sold across the country. Although the filters have excellent bacterial removal capa

This pilot train study compares the biofouling potential of two river waters that had been subjected to different pretreatment schemes conducting to equivalent microbial cells contents but different total and biodegradable organic carbon concentrations. Permeability and pressure drop of nanofiltrati

Biofoulants by autopsy of RO membrane and microbiological quality of the intake water were investigated with the samples obtained from existing RO desalination plant. The analysis of organic matters of the biofilm on the membrane surface showed that macromolecular substances such as proteins and car

Investigations were carried out to develop the best sustainable management system for domestic wastewaters. Sewer systems have a crucial significance within the current concept of wastewater management. It is suggested that sewer lines may be used as biological reactors to reduce pollution loads. Th

The experimental or theoretical method that can visualize or quantify the architecture of bio-cake formed on the surface of membrane is of great interest in understanding biofouling mechanisms, also controlling biofouling in a membrane bioreactor (MBR). This paper summarizes the methods for determin

A new pilot scale hybrid biofilm-suspended biomass membrane bioreactor was used to treat two wastewater streams generated in a fish canning factory. During a first stage, wastewater generated during tuna cooking with brine was treated. COD and N content were between 7.8–11.8 g COD/L and 1.2–1.8 g N/

Membrane bioreactors (MBRs) are commonly understood as the combination of membrane filtration and biological treatment using activated sludge. Development of a biofilm-MBR has been investigated combining a moving-bed-biofilm reactor with a submerged membrane biomass separation reactor. Treatment eff

Generally, membrane biofilm have been believed to be minimized during the operation of membrane bioreactor (MBR) for wastewater treatment and reuse. In this study, positive roles of membrane biofilm in the intermittently aerated MBR system were highlighted. During the long-term operation using real

Slow sand filtration is a biological means of surface water clarification that involves both biological and physical mechanisms. During this process, as time progresses, microbiological growth occurs, mainly consisting of micro-algae and bacteria which form a fixed microbial ecosystem (biofilm) on t

Good characterization of raw water quality and subsequent identification of the most appropriate pre-treatment are not sufficient to ensure successful functioning of a reverse osmosis plant. The Tan Tan demineralization plant was set up in July 2003 for 20 l/s production capacity. The brackish water
