Drum Filters

Why a Drum Filter?

We get asked all of the time “why a drum filter” and “how do they work” so here is a very brief overview.

Drum filters are fully automated pre-filters. The water enters the drum filter through the inlet chamber on the inlet side of the drum and then flows into a drum-shaped sieve.

Generally drum filters are fitted with a 60 micron or 70 micron stainless steel screen, so waste particles that are 0.06mm or 0.07mm in size or larger can’t go through the screen.

Waste particles will deposit on the inner side of the drum because they cannot pass through the drum screen from the dirty water side to the clean water side. This in turn will decrease the output flow of clean water through the drum causing the clean water level to lower.

The level switch which is located on the clean water side of the drum will detect this change in water level and send a signal to the controller to activate the cleaning process. The device itself decides when the spray nozzles clean the screen depending on how dirty the screen is. The dirt is then rinsed into the drain. You decide whether the spray nozzles use tap water (min. pressure 2 bar, max. 4 bar) or clean pond water to rinse the screen. The filtered water flows through the drum screen and then flows to your chosen biological filtration whether that is a moving bed or a Bakki shower for example.

Drum filters are a very low maintenance mechanical filter that sieves the pond water to a very fine particle size and offers exceptional water clarity with a minimum maintenance regime.

  • Filtreau Drum Filter

    £995.00

    The Filtreau drum filter is pretty much the cheapest drum filter currently on the market. Every aspect of this drum filter has been looked at to save every available penny throughout the production and design process. The drum is well made but made with a budget in mind.

    Utopia Koi has sold many Filtreau drum filters and was amongst the first Koi dealers to offer them for sale in the UK in 2016. They represent fantastic value for money. The drum filter is fully automated as you would expect. It has an integrated 40W amalgam UVC and is supplied complete from Utopia Koi with a high pressure pump for the spray bar.

    Utopia Koi believe that the drum filter requires a high pressure pump for the spray bar to work correctly so we supply it as standard with the super mini drum.

    The Superdrum Mini is designed to be used with a Gravity set up.

    Technical specification summary:

    • Input: 2 x inlets 110mm
    • Output:1 x outlet 110 mm
    • Materials: Used: Stainless steel / 316, FPM seal, high pressure PVC, silicone seal flow: 20m3

  • Air-Aqua Superdrum Combi Bio 30

    £2,395.00£2,495.00

    The Superdrum Combi Bio 30 delivers a complete filtration solution for Koi ponds up to 6600 Uk gallons with a maximum flow rate of 4400 UK gallons per hour hour. This is combined with the space to house a maximum capacity of 110 litres of biological media making this a very capable filtration system.

    The drum sieve removes any dirt greater than 60 microns (0.06 mm). The trapped dirt is then removed from the sieve automatically and flushed to waste.

    The automated cleaning cycle is triggered via a water level sensor. As the drum becomes dirty water flow is restricted reducing the water level on the clean water side of the drum triggering an automatic cleaning cycle. The sieve is cleaned with water from nozzles fed by the high pressure pump and the dirt is washed to waste.

    Once the water has passed through the drum and been mechanically cleaned it then flows into the aerated moving bed biological filter and returned back to the pond via your chosen water circulation pump.

    Utopia Koi believes that the drum filter requires a high pressure cleaning pump for the spray bar to work correctly so we supply it as standard with the Superdrum Combi 30.

    Oase ProfiClear Premium Drum filters are state of art. They are a modular system that offers a range of versatility that in our opinion cannot be matched by conventional filtration systems and allow a bespoke set up so that an individual ponds filtration requirements can be matched with ease.

    The ProfiClear Premium system works on a modular configuration (Drum, Moving bed and Pumping chamber with UVC) although all three elements can be used independently of one another if preferred.

    The Drum section has an integrated pressure pump and acts as a self cleaning mechanical solid removal filter which removes particulates down to 60 microns as quickly as possible reducing nutrient levels in the water and eliminating the need for regular cleaning in the Biological stages.

    The modular design of the ProfiClear premium drum filter system in our opinion is one of the most attractive features. As the ponds requirements change, if for example stocking levels increase or the pond is made larger, additional biological chambers can be added meaning that the filtration system does not need to be discarded but simply increased in size to suit the ponds new requirements.

    • Dimensions in mm (L x W x H) 830 x 600 x 820
    • Installation height over water level in cm: 11

    The ProfiClear moving bed module utilising Hell-X 13 bio-media, features an impressively large surface area for culturing nitrifying bacteria which are the micro organisms that break down fish waste products in a pond such as ammonia and nitrite.

    A moving bed biological filtration system is designed to keep the media in suspension with the aid of huge amounts of pumped air via your chosen air pump making a moving bed biological filtration system one of the most effective available in our opinion.
