The drum filter is one of the most ancient filters used in liquid-solid separation and the number one in mechanical filtration.
Thisequipment, made of stainless steel, is the most affordable and essential solution for many sectors. It has a vital character in particle filtration with high flow rates at low load. Among the industrial processes, we have:
In general, the drum filter is used for :
Thanks to the filter mesh, colloidal particles and other TSS will be retained, as they will not be able to pass through and will simply settle. These play a decisive role in the filter and will allow for the removal of TSS, by rinsing into the discharge gutter.
The objective of the drum filter is the same: to ensure water renewal and mechanical filtration of impurities and fine particles. And this, whether for:
Indeed, the drum filter can overcome many natural filtration processes to guarantee impurity-free water.
However, Many parameters are involved in the choice of a drum filter. That is, it depends on the size of your installation and your needs.
A drum filter is fed from the inside. Water laden with particles passes through the filter cloth and exits purified on the outside of the filter.
Water flows by gravity or with the help of a pump to the drum filter. This is where the water separates from impurities. For this purpose, the drum filter is equipped with an automatic control that monitors this situation. This control continuously measures the water level in the drum filter. This is possible with gravity systems located behind the filter and pump systems located in front of the filter. As soon as the drum filter clogs, the water level changes. In a gravity system, the water level drops behind the drum. In a pump system, the water level in front of the drum rises.
The drum filter is equipped with an automatic self-cleaning system that allows it to clean itself.
Indeed, when water flows into the middle of the drum, it brings with it all the debris it has collected along the way, which are retained by the drum itself until the water flow is restricted enough to lower the level in the drum and start the cleaning cycle.
However, sometimes after a long period of use, additional cleaning is necessary to keep the filter working properly. For this, it becomes necessary to perform manual maintenance.
Several parameters must be taken into account to determine the amount of water to use in a drum filter, such as the size of your pond and your installation.
At 1H2O3, we know that our users are passionate about their ponds and the well-being of their fish. They don’t want to get involved in the technical details of filtration. That’s why our 1H2O3 drum filters will give them what they are looking for. They are equipped with a very strong autonomy that requires very few attention, satisfying your expectations. To reach such result, we have innovated and perfected our drum filter, in order to achieve an extreme reduction of maintenance. We have worked on classic wear parts such as chains, straps or even plastic sprockets, replacing them with an intelligent system based on a force transmission by sprocket. Another key point of our system is its special bearings which are more resistant and therefore require less maintenance.
The washing processes are automatized. In addition, a wide range of special cleaning options will ensure that your filter will last a long time without the need for any attention. Through applications such as intensive washing preventing limescale formation.
Combining filtration and decantation provides a clear result and clean water free of fine particles. Both filtration and settling can be used to separate impurities from liquids, but there are differences between them.
Ideally, they should be combined for best results, starting with :
The main advantage of this technology is the fully programmed removal of solid waste – which does not simply capture particles during manual backwashing – and the proven mechanical design of the structure, which makes drum filters ideal for high flow rates.
The concept of particle filtration in drum filters is based on the mechanical blocking of particles. Therefore, the main goals of the development of this series of filters are:
A drum filter operates with a fine rotating mesh that mechanically retains suspended particles and self-cleans. It is ideal for high flow rates and low-maintenance systems. A sand filter, on the other hand, uses a sand bed to trap impurities through slow or rapid filtration, but requires more frequent backwashing and consumes more water. The drum filter is therefore more suitable for automated industrial installations or aquaculture.
Yes, the drum filter is perfectly suited for garden ponds, especially when they house fish like koi carp. It provides fine and automatic particle filtration, limits algae proliferation, and significantly reduces the need for manual maintenance. This makes it a high-end solution for maintaining clear and healthy water in private ponds.
The mesh size depends on the particles to be filtered:
A drum filter consumes very little electricity because its motor and pump only activate during the cleaning cycle, triggered automatically when the drum is clogged. On average, a standard drum filter consumes less than 100 watts per hour, making it a very energy-efficient solution, especially compared to manual washing systems or continuous filtration.
Yes, the drum filter can operate in gravity mode, i.e., without a pump, as long as the water level is sufficient to supply the drum. This system is highly valued for low-energy installations. It requires a specific design of the hydraulic line to ensure constant flow without interruption, with automatic water level monitoring.
