Introduction of Multimedia Water Filter

Multimedia filter can effectively remove suspended solids, colloidal, iron, organic compounds, pesticides, manganese, bacteria, viruses and other pollutants. It has a small filtration resistance, large specific surface area and strong acid and alkali resistance and oxidation, PH range is 2-13, and good anti-pollution. Quartz sand filter also has a unique advantage by optimizing the filter and filter design, implementing operation of the adaptive filter. Besides it has a strong adaptability of raw water concentration, operating conditions, pre-treatment process, that is, automatically form sparse in the top and dense at the bottom, which is beneficial in all kinds of operating conditions to ensure water quality. When backflush, quartz sand is fully spread out so that can have a good cleaning effect. Sand filter with a fast filtering speed, high filtration precision and interception capacity and so on.


A water multimedia filter is used to reduce the level of SDI (Silt Density Index), TSS (Total Suspended Solids) in the incoming feed water. Suspended solids consist of small particles such as silt, clay, grit, organic matter, algae and other microorganisms. Incoming feed water that is high in suspended solids can cause a high pressure drop and reduce the effectiveness of downstream filtration equipment such as membranes, reverse osmosis membranes, electrodeionization EDI, UV sterilizer and ion exchange beds, if the multimedia filtration is not used as a pretreatment.

Components of Multimedia Water Filter?

Filter Tank: This component will house the filtration media, it is either stainless steel, FRP or epoxy coated steel. Metallic tanks can handle higher temperatures and pressure.

Media: This is the filtration media that includes different layers of gravels, silica sand #20, garnet, and anthracite. This will depend on the quality of the filtered water that is needed. To achieve better water quality, it is recommended to add a layer of the garnet media.

Internal upper and bottom distributors: The bottom distribution system will prevent the media from escaping, while the upper distribution system will distribute the flow harmonically during the service cycle. The materials of construction can either be schedule 80 PVC or stainless steel. If your application has a high temperature water, we recommend stainless steel internals, tank and face piping.

Valves: The valves open and close according to the different cycles. They could be automatic electric or pneumatic valves for automatic filters, or manual valves for manual filters. For seawater, it is recommended to use nonmetallic valves. Some industries do not allow electric valves.

Controller: This component will control the automation of your filter. This could be a PLC or a digital stager or an electromechanical timer. This is usually a preference based on the main control in the facility or the building.

Face piping: Face piping will connect all valves that control the different cycles. It could be schedule 80 PVC, stainless steel or epoxy coated carbon steel. The material of the piping depends on the temperature or operating pressure, and if it’s an indoor or outdoor application.

Flow controller: This component is installed on the drain outlet to control the backwash flow rate and prevent the media from escaping to the drain.

Features and Benefits of FRP Media Tanks:

Standard polyester or chemical-resistant vinylester construction

Easy to handle and install

No rust or need for painting

Tested to 100,000 cycles without leakage

Most vessels tested and certified by NSF International to NSF/ANSI Standard 61 for material and structural integrity requirements.

Excellent compatibility with seawater RO

Superior corrosion resistance in many applications versus epoxy lined carbon steel metal

Less cost than epoxy coated steel and stainless steel

Lightweight –¼ the weight of steel – therefore, easier to handle

More skid (slip) resistant than metal

Non-conductive (prevents shorting out electrical equipment)

Good insulating material with reasonable thermal expansion properties


Features and Benefits of Epoxy Coated Steel or Stainless Steel Media Filter Tanks:

Heavier duty than FRP

Can handle higher pressure and temperature

Can be customized by adding hand-holes, manholes and various outlets

Good for outdoor application

Direct bolting to the skid

Good for pharmaceutical and beverage industries

Can handle vacuum not like FRP tanks

ASME code shaped head construction for durability and safety
