Activated carbon is basically used for two water treatment purposes and each work in totally different ways. 1. Chlorine Removal: Activated carbon may be used to remove chlorine with little degradation or damage to the carbon. Dechlorination occurs rapidly and flow rates are typically high. However, this process requires an extensive amount of surface area,…

Choosing the proper effect filters and determining the require filtration area can be accomplished using laboratory filtration trials. First decide on the appropriate level of clarity, and then choose a grade of filter medium that should provide this clarity, as based upon either particle distribution data or manufacturers recommendation. A number of filter grades might…

Sieve Retention There are a number of retention mechanisms employed by depth filters. Among them are: sieving, inertial impaction, Brownian motion, and adsorption. Sieving is the simplest form of particle retention, and results from the removal of particles that are larger than the pores that they are trying to pass through. . The retention is…

The chemical compatibility of the different membrane materials and of the most frequently used product ingredients is known and published by filter suppliers. If compatibility with a particular ingredient is unknown or doubtful, specific tests can reveal structural changes to the membrane, the effects on integrity test values, or the potential impact on a membrane’s…

O-rings are typically manufactured from a variety of elastomers that differ greatly in their compatibility with different types of fluids and gases. Selecting an elastomeric material for a sealing application is dependent on a variety of factors ranging from material hardness to application temperature, lubrication, and sealing pressure. Apart from this, one of the main…

Filters are rated on their ability to remove particles of a specific size from a fluid. The problem is that a variety of very different methods are applied to specify performance in this way. Pore size ratings refer to the size of a specific particle or organism retained by the filter media to a specific…

Cartridge filters is one of the simplest form of filters. Therefore, almost certainly it is the most numerous of all filter products. Cartridge filter is a type of filter that consists of a cylindrical element, usually made of paper, synthetic fibres, or membranes, that removes suspended solids from liquids by surface or depth filtration. The…
