Decanter centrifuge of accelerated settling

A decanter centrifuge operates on the principle of accelerated settling. Particles will settle in a viscous media according to stoke’s low, ...

Flocs' re-growth characteristics in circulation coagulation–membrane filtration process

by IWA Publishing  (May 11, 2015)

Membrane fouling can be significantly mitigated through circulating coagulation, floc breakage and re-growth under appropriate conditions. In this study, unified membrane filtration index (UMFI) was adopted to analyze the membrane fouling. The effect of circulating coagulation pretreatment on both flocs' average diameter and membrane ...

Effects of physical disturbances on media and performance of household-scale slow sand (BioSand) filters

by IWA Publishing  (May 11, 2015)

Point-of-use (POU) water treatment provides households in rural and remote communities with a means of obtaining greater control over their water quality and its effects on human health. One of the most prevalent POU interventions, the BioSand filter (BSF), is a household-scale, intermittently operated slow sand filter used by over 300,000 ...

The costs of small drinking water systems removing arsenic from groundwater

by IWA Publishing  (May 11, 2015)

The US Environmental Protection Agency (EPA) conducted an Arsenic Demonstration Program whereby the Agency purchased, installed, and evaluated the performance and cost of 50 small water arsenic removal treatment systems in the USA. A major goal of the program was to collect high-quality cost data (capital and operational and maintenance ...

The application of removal coefficients for viruses in different wastewater treatment processes calculated using stochastic modelling

by IWA Publishing  (May 7, 2015)

This study proposes that calculating and interpreting removal coefficients (K20) for bacteriophages in activated sludge (AS) and trickling filter (TF) systems using stochastic modelling may provide important information that may be used to estimate the removal of phages in such systems using simplified models. In order to achieve this, 14 ...

Particle removal in a novel sequential mechanical filter system loaded with blackwater

by IWA Publishing  (May 7, 2015)

A novel sequential mechanical filter system was developed as an alternative primary treatment method for onsite wastewater treatment. The filter combines traditional screening with a novel type of counter-flow filter using wood-shavings as a biodegradable filter matrix. This study tested the system in a batch loading regime simulating high ...

Modelling of moving bed biofilm membrane reactors (MBBMR) for on-site greywater treatment

by IWA Publishing  (Apr. 27, 2015)

The study evaluates with a mechanistic model the pilot plant results of a combined moving bed biofilm process and membrane filtration (MBBMR) treating single household greywater. It mainly includes the simulation of reactor hydraulics, degradation of pollutants, development of biomass and settlement of sludge. Iterative calibration was made with ...

Sea water desalination – potable water application case studies

by Genesis Water Technologies, Inc  (Apr. 20, 2015)

Challenge Facing challenges of clean water shortages in Tekoradi, Ghana with the burgeoning oil/gas sector in the area offshore, something had to be done to increase clean water supply to supply the growing needs of both the military base at Tekoradi and the surrounding community. Solution Knowing the water demands were increasing, Genesis Water ...
