Media Filters

Water Media Filters | Industrial & Commercial

Water media filters are most efficiently utilized during operations that require the removal of large amounts of suspended solids in water. Our media filters have continued to be major players in maintaining high water quality throughout the world's ecosystem through the filtration of harmful substances in rivers, lakes, streams, wells, etc.

Pure Aqua has over 20 years of experience as a global provider of water media filters for the improvement of low water quality issues as a result of elevated levels of suspended solids, sediments, turbidity, iron, and unwanted odors and taste from water. Our water filtration systems are designed to satisfy customer requirements and specifications.

Pure Aqua multimedia water filter systems are ideally suited for use where stringent water quality standards are required or where higher levels of suspended solids are present. These applications can include re-use applications, water pre-treatment applications for reverse osmosis and deionization systems or as a pre-treatment system prior to a disposable bag or cartridge filters.

Advantages:

The multi-media water filter systems operate for much longer periods of time (five or more times as long at the same filtration rate) before backwashing is necessary because the bed can hold more turbidity. Turbidity is trapped and held throughout the entire bed depth, rather than the top one or two inches.

Multi-media filtration is much better suited for use in a closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is virtually eliminated and the need for visual inspection is unnecessary. The use of pressure tanks (rather than open basins or filters) is an obvious advantage for point-of-use filtration and could also be of real importance in the filtration of small community water supplies. More rapid filtration flow rates in multi-media filtration allow the use of smaller diameter tanks with equal or better results. A very high degree of clarity is achieved in the filtered water because of the fact that the finer particles of garnet at the bottom trap finer turbidity particles.

Another important advantage is that multi-media water filters can clarify water at a much higher flow rate than a single-media sand filter (5.5 to 8 gallons per minute, as compared to 1.5 to 2.5 gallons per minute in a 12 inch diameter tank). This is 14 to 15 gpm per square foot of bed area, as compared to 2 gpm per square foot of bed area. This is a very important difference in the production of filtered water.

Pure Aqua's multi-media water filters (MF-1100, MF-1000, MF-600, MF-500 MF-450, MF-410 MF-400 Series) clarify water by removing sediment, turbidity, iron, unpleasant tastes and odors, suspended particles, and unwanted color, all of which are commonly found in surface water. They can be used in a variety of service conditions including, but not limited to: industrial, municipal, and institutional applications.

What is media filter in water treatment?

Multi media water filter systems use three media layers for multimedia filtration. These layers are called anthracite, sand and gravel. Their usefulness resides in the distinct differences in density between these layers of media. Anthracite has the least density among the three, followed by sand, and gravel.

Benefits of multi-media filters?

While conventional sand filters are composed of only one filtration media, media filters consist of multiple and are ordered in descending entrances. Due to their greater amount of layers, multi media water filter systems are capable of capturing and holding a superior number of fragments than conventional sand filters before backwashing is needed. Additionally, multi media water filters function for an extended amount of time in comparison to traditional sand filters, since they are able to trap sediment and particles throughout the entire filter bed. This filtration process creates cleaner water much at a much faster rate than conventional sand filtration. The media filter comes complete with 5 valves and automatic controller to accomplish the backwash cycles.

Why is anthracite used in media filtration?

Anthracite filtration media is a great filtration material to remove and filter out turbidity and total suspended solids for the purposes of TSS water treatment. Since the specific gravity of anthracite is lighter than sand, it is much used in combination with sand in dual-media filtration or with sand and garnet in multi media filters.

The anthracite has three major benefits when it is used in media filter:

  • Preliminary filtration for larger particulates
  • It compacts the sand media layer which provides better filtration results
  • When the filter goes to service mode, the anthracite will distribute the water evenly to avoid channeling
