Flow-through filters are used in large or medium-sized ponds, such as koi ponds. These filters stand above the water level and allow the flow of water to pass through while sending the remaining water back into the pond by gravity. They are best suited for ponds with high circulation needs and up to 140 m3. Users can use the filter function to limit the number of products displayed in the list.

Doorstroomfilter vijver is similar to dead-end filtration, but they work differently. The main difference is in the direction of flow. Flow-through filters are designed to allow liquid to pass through the filter media, whereas dead-end filters trap particles. The result is that a filter cake builds up on the filter media, which slows down the flow of liquid. Cross-flow filtration, on the other hand, removes this filter cake and produces a thinner filter cake and slower liquid flow rates.

Flow-through filters may not be the most suitable type of water filter. While both types are effective, there are some important differences. Downflow filtration tends to be less effective and requires the backwashing of the filter media. Downflow filtration tends to result in progressively larger media, which conflicts with ideal bed geometry. Upflow filtration, on the other hand, allows for the bed to remain compact.

The principal mechanism of in-depth filtration is surface capture. The depth and size of the filter media determine the surface area available for detritus capture. Similarly, grain shape affects the capture of particles. For example, angular particles are more efficient than round ones. The media size must also be chosen considering the speed of blockage and the ease of backwashing. Generally, the media size is between 0.5 to 2.0 mm.

The medium filter was developed in the Netherlands in the 1960s. It employs a simple metal grid that extends across the filter bed, which sits 15 cm beneath the surface of the sand. This grid helps delay the breakthrough of particles into the water, preserving the compaction of the sand and preventing localized penetration of flow. In-between the grid and the filter bed is the flow path, which is low resistance and can remove particles, while high flow paths help fluidize the sand in the upper flow path.

In-depth filtration is often the last physical barrier between particles and water. Consequently, the performance reliability of filters is crucial in complying with the requirements of regulatory bodies. Standards have become increasingly stringent over the past 50 years. The exclusion of Cryptosporidium oocysts, which are present in drinking water, has been particularly problematic. The efficiency and reliability of in-depth filtration have been a matter of concern in recent years.

High-flow filtration systems can hold more dirt and contaminants than other types of filter housings. As a result, high-flow filters reduce the need for frequent replacement. These units also require less maintenance and will reduce the overall cost of filtration. Flow-through filtration systems can also help businesses reduce their waste production and decrease their overall costs. So, consider installing high-flow filtration in your business today.
