Intermittent Sand Filters DESCRIPTION Intermittent Sand Filters (ISFs) have 24-inch deep filter beds of carefully graded media. Sand is a commonly used medium, but anthracite, mineral tailings, bottom ash, etc., have also been used. The surface of the bed is intermittently dosed with effluent that percolates in a single pass through the
Tertiary filtration is another application for membrane systems. A typical secondary treatment system is followed by a conventional sand granule media filter. The sand filter can be replaced by a membrane system to produce a high-quality effluent. The membrane system requires a smaller footprint compared to the sand filter.
ABSTRACT. Water pollution is a serious global issue. Various technologically advanced treatment methodologies, for example, activated sludge process, upflow anaerobic sludge blanket, membrane bioreactor, trickling filter, rotating biological contractor, oxidation ditch, are widely studied, well documented and adopted in practice.
