Multimedia-FiltrationMultimedia filtration is taken into account to be one of the most signification pre-treatment stages before any treatment systems to purify water to remove the suspended solids and decrease the turbidity before the main treatment filters or membranes.

During a conventional sand filter, lighter and finer sand particles are found at the top of the filter bed, and coarser, heavier sand particles remain at the underside after backwashing. Filtration takes place in the top few inches of the filter bed.

A multi-media filter is backwashed in the identical manner as a sand filter, using reverse or upward flow of water through the filter bed. The various layers of media retain their stratification because every material features a completely different density.


  • The multi-media water filter systems operate for a lot of longer periods of your time (5 or a lot of times as long at the identical filtration rate), before backwashing is critical as a result of the bed will hold a lot of turbidity. Turbidity is trapped and held throughout the whole bed depth, instead of the top one or 2 inches.
  • Multi-media filtration is much higher fitted to use in an exceedingly closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is nearly eliminated and the necessity for visual inspection is not sensible. The employment of pressure tanks, rather than open basins or filters, is an obvious advantage for purpose-of-use filtration and might also be of real importance within the filtration of small community water provides. More fast filtration flow rates in multi-media filtration allow the utilization of smaller diameter tanks with equal or better results.
  • A very high degree of clarity is achieved within the filtered water because of the actual fact that the finer particles of garnet at the bottom trap finer turbidity particles.
  • Another vital advantage is that multi-media water filters can clarify water at a a lot of higher flow rate than one-media sand filter (five.5 to 8 gallons per minute, as compared to 1.5 to 2.five gallons per minute during a 12 in. diameter tank). This is fourteen to 15 gpm per sq. foot of bed area, as compared to two gpm per sq. foot of bed area. This is a terribly important distinction in the production of filtered water. SD Enviro Engineers’s multi-media water filters clarify water by removing sediment, turbidity, iron, unpleasant tastes and odors, suspended particles, and unwanted color, all of that are commonly found in surface water. They can be utilized in a selection of service conditions including, however not restricted to: industrial, municipal, and institutional applications.

SD Enviro Engineers multimedia water filter systems are ideally fitted to use where stringent water quality standards are needed or where higher levels of suspended solids are present. These applications can embody re-use applications, water pre-treatment applications for reverse osmosis and deionization systems or as a pre-treatment system previous to disposable bag or cartridge filters.

SD Enviro Engineers multi-media water filter systems are also widely used as primary water filters for removal of suspended solids in incoming plant water or in waste water cleanup applications. With experience of SD Enviro Engineers water filter systems, you will receive economical solution that creates price for you while reducing your costs.
