Sub Title: Commercial Media Filters

Pure Aqua pressure filters 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.

Media Filters Used with the MF-400 Series

Pure Aqua supplies a wide range of filter media that meet industry standards for efficient and effective filtration.

Filter Media Types:

  • Activated carbon medium is used to remove taste, odor, organic contaminants, and chlorine as well as being used in many drinking water applications.
  • Sand is the most common filter media. Generally, fine mesh sand is coupled with a course grain support bed to remove suspended solids and turbidity. Graded in various ranges, Pure Aqua sand can be used as filtration medium or under-bedding depending on particle size and application.
  • Gravel has a highly spherical shape that promotes good flow and even distribution in support beds.
  • ProSand is based on a rare natural mineral. Its unique properties radically improve the performance and cost of media filtration.
  • Anthracite is recommended as a filter medium where additional silica in the water is not desirable and can remove lighter weight turbidity. Anthracite is typically used in applications where silica pick-up is undesirable.
  • Calcite media is specially graded calcium carbonate compound for neutralizing acid with consistent dissolving rates for water treatment.
  • Manganese Green-sand media is treated siliceous material for treating water containing iron, manganese and hydrogen sulphide through oxidation.
  • Filter AG is non-hydrous silicon dioxide with many advantages for the reduction of suspended matter.
  • Multimedia is required when maximum quality water is required and unwanted sediment is too small to be removed by standard media. It consists of multiple layers of increasing grain size to remove sediment as small as 10 microns.

 

Advantages of Multimedia Filtration:

  • Relatively inexpensive, no recurring cost of consumables
  • Proven process and most tested forms of water treatment
  • Systems are robust with no moving parts inside the tanks
  • Modular control valves designed for operational flexibility
  • Filtration media is inexpensive and long-lasting
  • Easily cleaned and maintained
  • Resistant to fouling (clogging)
 
Multimedia Filtration Operating Cycles
 
Service Cycle - Water flows downward through the media while solids accumulate in the media bed. The purified water passes through to downstream processes.
Backwash Cycle - When the filter begins to clog or when the head loss (pressure drop) through the bed increases, flow rates are reduced. To prevent degradation of water quality, the flow is reversed. This is directed by the control valve(s) to drain, carrying with it, the particulate matter that has built up during service. The required flow is specific to the media and is essential to proper cleaning of the media bed. For media filters, the backwash flow is always higher than the service flow rate.

Video on Water Filtration Systems Qatar

Water Filtration Systems included 5 sets of filtration systems for a major company in Qatar to remove chlorine, hardness, and suspended solids from well water. Each filtration system is composed of multi-layer filter, activated carbon filter and water softener. The filters were selected from our MF-400 series and softeners were selected from our SF-200 series. All of them came complete with FRP tanks and fleck 2850 top mounted valves. Each set was chosen to produce 25,500 GPD...more->
