Innovative Polisher For Ponds

The NEW Tempest Filter is an innovative polishing system for ponds. The Tempest Filter uses our latest filtration media, K+Media, to deliver crystal clear, healthy water.

Designed to be used in conjunction with any filtration system, the Tempest Filter offers additional mechanical and biological filtration. The Tempest Filter can be installed on a variety of set-ups and can be used on quarantine systems or as a standalone filter on smaller ponds up to 5,000 Litres / 1,100 Gallons.

 

The Tempest filter is easy to install and is simple and quick to clean, by way of a unique, patent-pending air syphon design. During the cleaning process, the air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.  

  

Independently Tested Filter Media

 

Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered. On a single pass, testing has proven our media capable of removing all particles down to 25 microns when used at the optimum flow rate. Not only that, K+Media is the result of extensive research and development and is moulded with minerals for faster maturation times.

Evolution Aqua filter media has been independently tested by Cranfield University and the IFTS (Institut de la Filtration et des Techniques Séparatives). IFTS International Filter Testing Services is the international reference for solid-liquid separation. Founded in 1981, IFTS is an independently regulated, ISO 17025 accredited, laboratory and research centre focusing on liquid filtration and separation science. IFTS quality management system is certified to ISO 9001:2015.

Installing the Tempest Filter

There are a number of ways the Tempest Filter can be installed on your pond system. Below are some typical installation ideas.

PLEASE NOTE: The slide valves fitted to the Tempest Filter allow connection to a 1½” pressure pipe. If installing the Tempest Filter using a flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent weld stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.

To allow the Tempest Filter to give the best performance, it is important that the flow rate is no more than 5,000 litres per hour. Some of the installation examples show an aby-pass that will enable you to increase the flow through the pond.

TYPICAL INSTALLATION WITH A GRAVITY-FED FILTER

You can install a Tempest Filter after a primary filter on a gravity-fed set-up, such as the Nexus+, and after a UV Clarifier, such as an evoUV. The slide valves on the Tempest Filter connect to a 1½” pressure pipe.

The installation example shown below has a by-pass that will enable you to increase the flow through your pond while maintaining the optimum flow through the Tempest Filter. Installing ball valves on the pipework will help you regulate the flow. The return from the Tempest can go back to the centre of your Nexus+ or back into the pond.

TYPICAL INSTALLATION ON A PRESSURISED SYSTEM

You can install a Tempest Filter on a pressurised system with a K1 Micro Bead, Nexus+, EazyPod. The slide valves on the Tempest Filter connect to 1½” pressure pipe.

The installation example shown below has a by-pass that will enable you to increase the flow through your pond while maintaining the optimum flow through the Tempest Filter. Installing ball valves on the pipework will help you regulate the flow. The return from the Tempest and the K1 Micro Bead go back to the pond.

Image

TYPICAL STANDALONE TEMPEST FILTER INSTALLATION

You can install a Tempest Filter on a quarantine system, or a standalone pond up to 5,000 litres, at the side of a pond or above the pond.

The slide valves on the Tempest Filter enable connection to a 1½” pressure pipe. If installing the Tempest Filter using a flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.

Image

TYPICAL SKIMMER LINE INSTALLATION

You can install a Tempest Filter on a skimmer line.

The slide valves on the Tempest Filter enable connection to a 1½” pressure pipe. If installing the Tempest Filter using a flexible hose you will need to fit a reducing sleeve
(EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.

Image

MODULAR TEMPEST FILTER INSTALLATION

On larger systems that require a higher flow rate, multiple Tempest Filters can be installed in a modular system. The slide valves on the Tempest Filter enable connection to 1½” pressure pipe. If installing the Tempest Filter using a flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.

It is important that each Tempest Filter can be isolated using the slide valves so that cleaning can be carried out independently. Although on the installation diagram below we show two filters into one return line, independent return lines will allow you to observe the flow rate through both Tempest Filters and balance accordingly.

Technical Specification

How The Tempest Filter Works

Water is pumped up through the Tempest Filter. The K+Media moves to the top of the filter, becoming a mechanical barrier that traps debris as it flows through the system. Waste is trapped in the K+Media until the cleaning cycle dislodges it and it gets flushed away.
