To get an estimate, your provider will use a method known as a GFR calculator. A GFR calculator is a type of mathematical formula that estimates the rate of filtration. It does this by comparing the results of a blood test that measures creatinine, a waste product filtered by the kidneys, with other information about you.

filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product. In some processes used in the production of chemicals, both the fluid filtrate and the solid filter ...

Filtration Definition. Filtration is the separating of substances based on their different physical and chemical qualities. Typically, we think of it as the removal of solid particles from a mixture containing both solids and liquids. In this process, we refer to the collected solid material as the residue and the fluid material as the filtrate.

Description of techniques, methods and equipment. Filtration equipment operates either by the application of pressure (pressure filtration) to the feed side or by the application of a vacuum (vacuum filtration) to the filtrate side. The two main types of pressure filtration are the plate and frame filter press and the leaf filter.

Direct filtration operates well on micro-flocs and requires untapered high energy flocculation ( Section 7.12 ). The filters used are either monograde sand (ES 0.9 mm) deep bed (0.9–1.0 m) or anthracite-sand containing 0.3 to 0.4 m anthracite (ES 1.3 mm) and 0.6 m graded sand (ES 0.55 mm) ( Sections 8.2 and 8.6 ).

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth

Filter sampling involves passage of air through a filter, where the particles are trapped. Filtration requires a vacuum source, as in the preceding three methods, making it a less portable methodology. Filter sampling involves using a filter holder containing an appropriate membrane filter, which is then attached to the vacuum source.
