Flow through Filters.

This range is used when Cartridge Filtration would not be sufficient but an Automatic Back-washing Filter would be too expensive and not absolutely necessary.

The water enters the media through the inlet connection and flows through the media where contaminates are removed.

The water exits through the outlet. The media in these units will require more frequent change-outs than in a back-washing unit, but are more economic to purchase.

With the proper selection a wide variety of contaminates may be removed using this type of filter including the following:

Turbidity
Iron/Manganese
pH correction
Taste, Odour and Smell

NOTE:
Table below shows approximate flow rates for Carbon Filtration as this is the most commonly used media for this type of filter.
These flow rates are merely a guide and a full water analysis would need to be reviewed to give actual sizes for each application.

Automatic Back-Washing Filters

Overview:
We design and manufacture a range of Automatic Filters to suit site specific problems. We choose the best available media after a full water analysis has been performed. Concentrations of contaminates, Flow rates, Water usage and Pumping capacity are also included in any design calculations.

System Management and Backwashing:
During service an Automatic Filter will collect the contaminates from the water and hold it on the media. In order to remove the accumulated deposits from the filter bed, the water flow through the filter is reversed (back-washed). Water is run to drain at a high flow rate to separate the filter media from the deposits. The deposits being washed to drain.
A control valve mounted on the top of the vessel completes the backwash cycle automatically. The intervals and times are set during installation. Backwash and fast rinse times are set per cycle to suit individual conditions.

With a review of a full water analysis and careful selection and blending of medias we can use these filters to remove a large variety of contamination from water.
Because these filters back-wash the contaminates will be flushed to drain and the bed of media will be re-classified thus preventing channeling through the bed.
