Filtration Process and Alternative Filter Media Material in Water Treatment

Coarse media filtration--an alternative to settling in wastewater treatment.

In this paper coarse media filtration has been analysed as an alternative to the traditional settling in primary, secondary and tertiary treatment of wastewater. Various filter media configurations were evaluated for enhanced primary filtration. It was found that a dual media configuration based on Kaldnes biofilm media (1 and K2modified) were most suitable when taking both separation efficienc...

Removal of Escherichia Coli through Rapid Depth Filtration by using Burnt Oil Palm Shell (BOPS) as a Filter Media in Water Treatment Process

Escherichia Coli is the ubiquitous microorganism contaminating the drinking water. This study is using granular bed filtration as a vigorous, simple and economical method to prevent the penetration of bacterial contamination, by discovering an alternative filter media from local source namely the burnt oil palm shell (BOPS). The result indicated that dual media BOPS/sand were higher reduction a...

Dataset on the spent filter backwash water treatment by sedimentation, coagulation and ultra filtration

During operation of most water treatment plants, spent filter backwash water (SFBW) is generated, which accounts about 2-10% of the total plant production. By increasing world population and water shortage in many countries, SFBW can be used as a permanent water source until the water treatment plant is working. This data article reports the practical method being used for water reuse from SFBW...

Effect of Filter Inhomogeneity on Deep-Bed Filtration Process – A CFD Investigation

Aerosol filtration in fibrous filters is one of the principal methods of removal of solid particles from the gas stream. The classical theory of depth filtration is based on the assumption of existing single fiber efficiency, which may be used to the recalculation of the overall efficiency of the entire filter. There are several reasons for inappropriate estimation of the single fi...
