The deep bed filter is suitable in case of average contamination.The hydrostatic pressure of a flatbed filter is low. The flatbed filter is the most suitable in case of low contamination.The buffering could be done in a breaker tank that contains a process pump that pumps the water to be treated across the band filter.Ĭontamination Depending on the contamination there are different types of filters that can be chosen from: This is done, for example, with filter backwash water. When a volume of water must be filtered briefly, it is preferred to buffer this volume and then treat it in batches. When choosing a cloth filter, three factors matter: the desired flow in m3, the contamination and the space available.ĭesired flow You can choose to apply the cloth filter either in full flow or in bypass. Since the contamination is discharged via the cloth, the cloth filter does not require any rinse water for cleaning.Ĭhoosing a cloth filter When you want to use cloth filter as a filter technology, you can choose from different types of cloth filters. The cloth filter system will then automatically renew the filter papier. After a while, the pores will be ‘full’ and the cloth will be saturated. Here the following applies: the smaller the pores in the filter paper, the more pollution is filtered from the water.
A cloth filter is used for the filtering of different water flows within glass horticulture companies, such as the drain water of ebb and flow systems, basin water, rinse water of sand filters and bypass filtration of a clean-water tank.įilter principle A cloth filter works according to a simple principle: when the water to be purified is guided across the filter paper, the dirt particles from the water that are larger than the pores in the filter paper, will remain. How does cloth filter work, as a filter technology? A cloth filter - also called bandpass filter or paper band filter - removes solid particles from the water by means of filter paper, applying a filter accuracy of approximately 15 to 50 microns.
