What is bed expansion?

Bed expansion in media filters is defined as the level of increase in the volume of filter media. There is a resting or a working bed depth and an expanded bed depth. This is the level to which the media needs to rise to during upflow or backwash.

Types of media that require backwashing and expansion to remove trapped foreign particles include:
  1. Filter Sand
  2. Zeolites
  3. Glass
  4. Ion Exchange Resins
  5. Anthracite
  6. Granular Activated Carbon
  7. Greensand and others
Expansion is caused by a flow of water (and air where used) at a certain velocity (depending on the bulk density of the media) to lift and separate the media bed. Usually, bed expansion is expressed as the percent of increase in bed depth.

The Rotorflush Filterpump is a submersible pump with an integral self-cleaning intake filter. This unique self-cleaning intake filter enables the pump to operate in water contaminated with a high degree of suspended solids without blocking or affecting the performance of the pump.

How it works:

A rotating impeller with two angled jets sits inside the intake filter screen, the blue arrows show the main flow of water being sucked into the pump through the screen. The red arrows show filtered water inside the filter being diverted into the impeller and ejected out through the rotating jets.

The Rotorflush RF Series are self-cleaning filter screens for attachment to the suction hose of a surface mounted pump. Fitted with either tough nylon filter mesh or stainless steel mesh for coarser applications.

How it works:

The RF Series have an internal cleaning rotor that is powered by taking a ‘T’ off the output of the pump to supply the internal cleaning rotors – this supply continuously backwashes the mesh screen, blowing away anything that may cause it to block.

The RF100AN Analyser Filter System is a revolutionary new product specifically designed to provide filtered samples for analysers and dosing pump systems with almost no maintenance. It is excellent for filtering difficult samples contaminated with suspended solids for supply to chlorine, ammonia and other analysers.

Glacier Filtration will be exhibiting at the 82nd Victorian WIOA Water Industry Operations Conference & Exhibition held in Bendigo on the 4th and 5th September 2019.

Benefits of Installing a Media Trap Downstream of your Filtration Plant

Why Do I need a Media Trap

Media traps offer an inexpensive way to avoid the expensive problems and chaos that develop when ion exchange resin or other media unintentionally reaches process areas or downstream process equipment.

What is a Media Trap

A media/resin trap is a very simple screening device which is installed on the downstream side of your Ion Exchange/Media Filtration Plant. The slots are small enough to retain upstream ion exchange resins and other filtration media in the event of a broken lateral or under drain failure without increasing friction loss in your system. 

24 x Polyamide Pressure Vessels installed in two (2) Containerised Water Treatment Plants by one of our clients. They were chosen by our client for their flexibility in design options and consistency in quality and reliability.

Installing a sight glass at top bed height level enables visual inspection during service and backflushing and top and bottom dome access ports, provided our client the extras they needed for ease of successful plant operation without compromising on vessel integrity.

NO MORE BLOCKED PUMPS!  The revolutionary filterpump is a unique product combining pumping and filtration into one unit and is virtually impossible to block.

Glacier Filtration now offers a huge range of larger filterpumps giving you a far greater choice of flow rates and pressures.

The submersible pumps with integral self-cleaning intake screens can now be used to pump up to 150m3 / hour of dirty water without you worrying about your suction intake, pump or other equipment blocking.

GF-GS20 Reverse Rinsing screen filters ensure a continuous supply of filtered water.

The GS20 is a high flow capacity water filter used to remove sediment and debris from residential, commercial or industrial water systems.

Used as a prefilter, the GS20 protects elements of the water system, including specialized treatment devices and other common fixtures and appliances. The flow, filtering capacity, and ease of cleaning make the GS20 the ideal filter for the most demanding applications.

Glacier Filtration is proud to be exhibiting at the 44th Queensland Water Industry Operations Conference and Exhibition to be held at the Bundaberg Multiplex Centre on the 5 & 6 June 2019.

If you are an operator, manager, engineer, consultant, professional or someone who is working in the water industry or just has an interest in water, then this is a must attend event.
