The Marlo MFS Automatic Backwashing Media Filter

The Marlo MFS Automatic Backwashing Media Filter

The Marlo ‘MFS’ Series is one of the premier, high-quality, automatic backwashing media filter systems. It’s designed to effectively remove dirt, silt, and rust as well as a variety of other suspended particles from streams of water. The automatic backwashing system of the Marlo MFS gets rid of any trapped pollutants inside of the filter bed and disperses it down the train.

The Marlo MFS covers a vast range of industrial and commercial applications, including chlorine removal, iron removal, and turbidity reduction. This flexible and powerful media filtration solution offers the following operating parameters:

  • check
    Temperature Ranges: 35 - 110 degrees F
  • check
    Electrical: 120 VAC, 1-Ph, 60Hz
  • check
    Inlet Pressure: 30-100 psig

Marlo MFS Series Standard & Optional Equipment

The Marlo MFS is designed for larger industrial and commercial applications with multi-tank parallel systems common for higher flow rates. The tank diameters can be designed up to 144" while the service pipe connections to 8" flange are available.

Each media tank is engineered of carbon steel with Safety Blue exterior paint. The interior of the tank is lined with NSF 61-rated epoxy coating. The exterior piping is crafted from extra-durable galvanized steel pipe and cast iron fittings. While the control valves have a painted cast iron body, the internal distributors are made from Sch 80 PVC/ABS.

Available Filter Medias for the Marlo MFS

The Marlo MFS offers a vast range of component options and filter media to meet your exact needs. You can choose from the following filters.

'MID' Multimedia Filters

These high-efficiency, in-depth filter systems utilize a layered bed of silica sand, anthracite, and two types of garnet for outstanding filtration down to the order of 5-10 micron. With the highest possible service flow rates on a pressure type filter, the MID Multimedia Filters for the Marlo MFS are ideal for the final filtration of well water supplies and the majority of city water supplies. While highly versatile, the MID Multimedia filters are not suggested as the primary filtration means for very high turbidity applications.

'AGA' Filter-AG Filters

AGA Filters are general service systems that use a non-hydrous silicon dioxide solution for removing suspended solids to the micron range between 20-40. The irregular surface and fracture edges of the media create less pressure drops by promoting deeper sediment penetration without blinding and caking the bed surface. With a weight that is lighter than the standard sand media, the Filter-Ag offers better water conservation and requires lower backwash rates.

'MGA' Iron Removal Filters

By utilizing manganese greensand filter media, MGA Iron Removal Filters are designed to reduce hydrogen sulfide, manganese, and iron. Manganese greensand is created from a glauconite coated with different variations of manganese oxides.

Hydrogen sulfide, soluble iron, and manganese are oxidized and precipitated by making contact with these oxides. Afterwards, the precipitates are filtered and removed in the backwash step.

The oxidative capacity of the filter is restored through periodic regeneration.

'ACA' Carbon Filters

ACA Carbon Filters are engineered to reduce odors, tastes, and dissolved organic material from industrial and municipal water supplies. These filters are most regularly used to remove free chlorine from supplies of water as pretreatment to reverse osmosis and other water treatment systems. Numerous types of activated carbon are available for unique specialty applications.

'ANA' Neutralization Filters

With ANA Neutralization Filters, screened calcium carbonate and crushed calcite media are used to neutralize low pH or acidic water supplies to a less corrosive, neutral effluent. The calcium carbonate is slowly dissolved on contact to increase the pH, which reduces the possibility of leaching of copper and other metals commonly found in piping systems.

From time to time, you’ll be required to add media as it is used in the filter vessel. Because the calcium level will increase in effluent water, you may need a water softener after the neutralizing filter.
