Mechanical filtration

Water filtering equipment

Filtering systems on individual, collective and industrial installations are usually designed to filter sediment, which is defined as matter in suspension in the water (mineral, metal and organic particles) greater than 5 µm in size. It is also possible to filter specific substances such as nitrates, pesticides, herbicides, heavy metals or bacteria by using the appropriate filtering media.

How do filtering systems work?

The filters comprise a filter case and filtering media, which are generally made of a porous material that will retain impurities. The filter cases may be of various materials, depending on the application (stainless steel, brass, plastic), of various technologies (manual, manual self-cleaning, automatic self-cleaning). The filtering media may also be of several types (bags, meshes, cartridges), either expendable or washable. The impurities contained in the water are retained by the filtering media when they pass through the filter case. They are then eliminated in several ways, by purging (manual or automatic), by washing or by replacing the filtering media when it is saturated.

What are their applications?

Filtering systems may be installed for individual, collective or industrial applications. The filtering elements are generally intended to protect the basic or specific equipment in an installation, whether they are installed on the main incoming water supply point, on another water point or on an industrial process.
