RK2 Systems Mechanical/Polishing Filters

Effective Solids Capture with our PMF Pond Filtration Systems

PMF-10, PMF-5

PMF-10, PMF-5

Filter Construction

Our 18" thru 24" diameter PMF Thermoplastic Series incorporate the latest advances in thermoplastic technology featuring a polymer mix that is abrasion proof for long lasting performance and durable protection against the elements.

Features:

For larger volume applications, we offer our commercial grade 24" thru 48" diameter PMF Fiberglass Series. All Fiberglass bodies are manufactured from the highest grade of non-corrosive materials and employ the latest in fiberglass winding technology. We guarantee these filters will outlast traditional pond filtration systems and will offer owners many years of trouble free operation. Our deep bed filters are the key to our success. Within each PMF Filter, our deep media bed improves the filtration efficiency over standard high-rate filters by providing enhanced in-depth filtration and increased dirt capacity.

The filter's 19" to 39" media bed ensures that finer dirt particles and colloidal substances are retained to a far greater level than a filter with a shallower bed depth.

Media Options

Clay Pellet Media

Mechanical/Bio-Filtration with our all natural Clay Pellet Media

Our PMF (Pressurized Media Filters) are specifically designed to provide superior mechanical filtration in ornamental fish ponds and outdoor water features. When combining these PMF Filters with our 4-8 mm Clay Pellet Media and our specially designed bead laterals, users get a true two stage mechanical and biological filtration system. The shape and varied size of our Clay Pellet Media provides efficient solid waste capture and water polishing while providing a stationary "fixed bed" mechanical filtration process offering users with 50 um - 100 um solid capturing capabilities. The composition of our Clay Pellet Media's porous skin and core inside each pellet provides users with a far greater amount of surface area, (230ft. /gallon), when compared to traditional filter media currently available. This media porosity also offers a protective environment for nitrifying colonies of beneficial bacteria, and in turn, optimal bio-filtration. In selecting our Clay Pellet Media inside our PMF Filters eliminates the need for a secondary stand-alone bio filter that requires more space, additional plumbing and expense to homeowners.

Glass Bead Media

Glass Bead Media

Superior Filter Media

Manufactured from pure glass, Glass Bead Media are a new generation of filter media, capable of providing water of superior clarity. Its spherical shape results in low coefficient of friction, reducing backwash requirements, saving pond owners both time and water.

Superior Clarity

Glass Bead Media have a small effective size of only 0.6mm to 0.8mm. Its narrow particle size range allows in-depth filtration and extends operating cycles between backwashing. Glass Bead Media have been laboratory tested to be able to effectively filter down to below 3 microns.

Save Water

Glass Bead Media's spherical smooth shape, results in a low coefficient of friction, reducing its backwash water requirements. Glass Bead Media backwashes with up to 20% less water than sand, saving time and water.

High Purity

Glass Bead Media are manufactured from pure glass and chemically inert. Glass Bead Media have been independently lab tested for leeching contaminants and found to be well within Australian Drinking Water Guidelines.

Safe and Smooth

Glass Bead Media are spherical and do not have any sharp edges. They are safe to handle and safe to service. If there is ever a failure of the filter's laterals and Glass Bead Media flow into the pond they pose no risk of injury to fish.

Time Saving

Glass Bead Media are easy to install and enables a rapid start up of the media filter. Its high purity means very little backwashing is required to cleanse the filter media, prior to commissioning the filter.
