In water treatments we recommend our Pumice Filtration Media as it is a specially selected lava rock for this application. Our pumice filtration media is used extensively throughout the UK and Worldwide as a filtration media for DMF pre-treatment prior to RO and SWRO.
We have supplied into new installations and existing plants where our pumice has been proven as an alternative to anthracite and at a much lower capital cost.
All pumice filters employ the same basic principle; a rapid gravitational filtration of raw water through a granular media. Pumice can be used in single, dual or multi media filters in conjunction with sand and gravel depending on the quality of water to be treated.
The versatility of pumice enables it to be used to solve difficult filtration problems. Filtration can be achieved within a rapid gravity or pressure filter, with optimum filtration performance ensured through regular backwashing via nozzles in the filter floor.
