Specification of Pumice Stone Water Filter Media

Pumice Stone Water Filter Media

Pumice is a commodity that is being hunted by the big industrial world. The benefits are many, pumice can be used for filters, planting media, so that it can be used as a softener for textile materials. There are 2 types of pumice based on color, namely red pumice stone and white pumice stone. The difference is in the cavity or pores. Red pumice has a large pore structure, therefore its absorption capacity is better than white pumice. However, white stone also has the advantage that it is denser and has a fairly low melting level in water. However, pumice stone is classified as a type of stone that has wide pores so that it can absorb micro-shaped dirt that is in water molecules.

Pumice has high vesicular properties, contains a large number of cells or has a cellular structure due to the expansion of the gas foam contained in the pumice stone. The large number of pore spaces makes pumice is limited by thin walls so that it makes this rock has a fairly low specific gravity.

Pumice has been widely used in the use of filter media for seawater, drinking water and wastewater. Pumice or pumice is a filtration medium that is widely used in the desalination process. The basic principle of pumice filter media is the same as other media; rapid gravity filtration of raw water through granular media. The versatility of the pumice filter media can be achieved in pressure filters, with an optimal process that can maximize routine backwashing.

Pumice filtration media is also used for pre-filters in salt or brackish water treatment prior to the desalination process. This pre filter process removes micro-sized impurities before passing through the next stage. Pumice filter media is also able to reduce chloride levels in brackish water when added with other media such as zeolite.
