A rainwater filter is the most important component of a rainwater system, even more important than the rainwater tank or pump. An oversized or undersized tank slightly increases or decreases the efficiency of the system. An oversized or undersized pump will make sure that the pressure is low or will consume too much energy. In both cases the efficiency will only decrease by a few percentage. However this is totally different regarding the filter. If a filter malfunctions, is clogged up, or quickly becomes soiled there will be little or no rainwater in the tank. This will make the automatic rainwater system change to tap water without anyone noticing this, until someone discovers that the filter is not working properly or has to be cleaned. Thus the use of a rainwater system is obsolete with a badly operating or clogged up rainwater filter. This shows that the purchase of a proper rainwater filter is essential. Before using rainwater in your house, you first want to make sure that the rainwater is clean. GEP has developed filters based on Trident filter technology for this purpose. This technology ensures that dirt particles will be separated from the rainwater before it is stored in the tank. A Trident filter consists out of a filter grid of special triangle shaped lamellae which are faced opposite of the water flow. The lamellae are tilted in order to ensure that the rainwater is forced through the gaps between the lamellae. Dirt particles will remain on the filter grid and are discharged to the sewer. Dirt particles can clog up the gaps of the lamellae after a period of time. Therefor it is essential to keep the filter clean. A dirty filter will lower the inflow of rainwater to the tank and thus lowering

the efficiency of the rainwater system. To make sure that your filter is cleaned in time, all Trident filter are available with a nozzle including an automatic on and off switch. This means that with a Trident filter you are assured of clean rainwater and an efficient rainwater system.

The grid of a rainwater filter is very important. The bigger the better, which is logical. The more square centimetres of filter grid the better. This will allow the rainwater to have sufficient space to penetrate the filter grid to the rainwater tank. The material used in the filter is also of importance. A mesh-like woven material

clogs up faster because every mesh creates a constriction in which dirt particles can become stuck which will result in a clogged up filter. Additionally an effective filter grid is important. So called ‘independent flow surfaces’ are better than a filter surface which is dependent on the number of litres per minute.

The special tilted lamellae of the Trident filters are also electrolytic polished. During this electrolytic polishing a layer of material is dissolved at the surface. Electrolytic

polishing has an equalizing effect. The surface of the filter grid is thus much smoother than untreated stainless steel. Under a microscope, the untreated surface of stainless steel shows a jagged and spiky structure. While the electrolytic polished surface shows a more equalized, undulating structure. This means that the electrolytic polished surface has much better adhesion characteristics and thus less chance of bacterial growth in the pores. This will also reduce the adhesion of dirt. The smoothness is clearly visible, it shines similar to chrome. In addition, electrolytic polishing of stainless steel has another important benefit. The iron in the surface dissolves much faster than nickel. This means there is an enrichment of nickel in the surface layer which means that the stainless steel is even more corrosion resistant.

Trident filter technology in practice.The Trident filter grids are of high quality massive stainless steel. This means that the risk of corrosion or damage is small. Due to the unique tilted lamellae of the Trident filter surface every square centimeter has a highly efficient effect. The water is, as it were, scraped off as a sort of cheese grater. Dirt particles do not clog up because the Trident filter grids partly submerge once the tank is full. Stubborn dirt particles are sprayed off the filter grid by (optional) filter nozzles.

Why does the Trident rainwater filter have such a long lifespan and such high performance?

• Trident filter grids are made of high quality massive stainless steel• A very smooth dirt resistant surface is created by electrolytic polishing• Trident filters have an ‘independent flow filter surface’• Trident filters have a large filter surface• Trident filters have tilted lamellae which enlarge the efficiency per square cm• Triangle shaped lamellae don’t clog up fast• Dirt is drained off when the tank is full• Trident filters are (optional) expandable with automatic cleaning nozzles.

Product benefits

DescriptionThe Trident 150 tankfilter is developed for rainwater filtration. The Trident 150 filter is fitted in a storage tank between the inlet and the outlet without any additional connections. The filter housing is made out of polyethylene (PE). The filtration grid consists out of lamellar shaped stainless steel blades equipped with a handle for easy installation. Cover is included, brass nozzles and stainless steel rodent valve are optional.

DescriptionBased on the capillary effect of rainwater. The rainwater is restrained and forced through the filter by the special shape of the Trident filter. The special blade shaped Trident filter grid filters the water extremely efficient and effective.

The Trident technology is characterized by a rapid separation of waste and clean water, and with a maximum performance. Also, there is a slight drop between supply and discharge. The Trident 150 filter also provides an overflow with skimmer-effect. The main benefit is that this does not require an additional connection for the overflow.

To minimize service and maintenance, all Trident filters can be equipped with nozzles. The use of nozzles allows automated cleaning of the Trident-filter grid. This ensures a high long-term efficiency of the filter as well as minimal maintenance.

The Trident technology by GEP guarantees a good filtration of rainwater with a high efficiency, low maintenance and a slight drop in the pipes.

GEPhasdevelopedauniquefiltershaftwhichappliestoallplastictanksbutalsotoGEPconcretetanks.15yearsofexperiencehasallowedGEPtodeveloptheuniqueVaritankfiltershaftwiththefollowingfeaturesandadvantages.

1. The shafts slide over each other and are connected with a rubber sealing ring to provide an optimal closure. An easy, time-saving and water tight solution. This system prevents the usage of sealants, welds or masonry mortar2. It is possible to rotate solely the shaft which means that less connection pieces are required.3. The sawable and telescopic shafts will reduce your costs immediately due to the lower labour intensity. Masonry is no longer required these days! The shafts can be sawed or raised in an instance.4. The upper shaft is telescopic compared to the inner shaft. This allows precise installation of the cover equal to the ground level. This can also be done in a later stage when the garden is finished. This also reducs the required connection pieces and thus money and time.5. The shafts are expandable with extra connections which can be installed fast and easy.6. The cover set is rotatable in relation to the shaft and tank. This allows perfect installation with regards to the joints. The cover can be placed slightly tilted to allow perfect installation on a slope.

In short: the shafts and covers are telescopic, cuttable, rotatable and extendable. The wide assortment of covers which fit on these shafts allow a (child)safe and “invisible” covering.

Varitank 150/325 man-hole filter

Varitank-Manhole filter installed in a concrete tank

With the Varitank-Manhole filter labor intensive customization is no longer required. The plastic collar simplifies the installation. All Varitank-Manhole filters are equiped with a plastic collar which are placed in or on top of the tank. This allows the placement of a plastic raiser with an integrated rainwater filter. This universal system is very flexible as well as easy and quick to install. Also important is the fact that this can be implemented without the use of a crane or other machinery. Additionally, the access to the rainwater tank is very child safe due to the closed filter platform.

The shaft is rotatable, thus connecting the pipes is fast and with a minimum amount of connecting pieces. The plastic shaft is fast and easy shortened with the use of a saw in order to level the cover perfect with the ground level. Additionally, the cover is also telescopic and rotatable so that the wide assortment of covers can fit. These covers can all be placed and installed by hand.

The Varitank-Manhole filter can be installed on concrete tanks, plastic Blueline tanks, Flatline tanks and other similar tanks.

In short:• Low maintenance due to self-cleaning effect• Easily disassembled• Provides overflow skimmer effect• ready to use connections for supply, overflow and casing (ø110) • Accessible manhole, rotatable, telescopic and can be shortened, very child safe• Walkable cover, also available with car or truck resistant cover

• Alarm sensor which detects backflow• Filter nozzle for the Trident filter• Cover cover for heavy traffic on request• Fine filter 100 µm filter bag• Rodent valve• Temporary construction cover• Child safe cover, class A walkable• Child safe cover, class B passenger cars• Cover, class D, heavy traffic• More covertypes coming soon!

Commercial Trident

• SlightdropbetweenInandOut• HighqualityTridentFiltertechnology• Prefabsproeiers• Prefabnozzlesforautomaticcleaning• Veryhighefficiency

Product benefits

This commercial Trident filter has been developed to be used in medium to large size rainwater harvesting systems. The highly efficient filtration process via horizontal stainless steel filter grid with optimised profile ensures maximum rainwater collection rate and filter efficiency, passive self-cleaning and optimal nonpotable water quality in the rainwater storage tank. This produces precious, hygienic and soft rainwater for gardens, washing machines, toilet supply as well as for numerous industrial and commercial applications, e.g. water for cooling towers, car/lorry washing or other process water where rainwater usage is clearly of advantage. Leaves and the majority of particles are retained on the grid until the self-cleaning process starts. The construction and the dimensions of the grid make a high collection rate of up to 99% possible. Self-cleaning: The filter grid should be prefered located below the maximum water level of the tank. If the tank overflows, the filter will be under water and the floatable dirt will be transferred into the drainage system. The nozzles allows easy and automatic cleaning of the filtergrid.
