The use of our Pumice Filtration Media in water filtration applications is increasing worldwide. Pumice Filtration Media is used as an alternative to sand and anthracite in the treatment of potable water treatments, seawater reverse osmosis (SWRO), desalination and waste water treatments. Pumice filtration media is increasingly being specified for contracts involving pre-treatment prior to reverse osmosis (RO) and desalination, in both new and refurbished plants particularly in the Middle East. This is due to its extremely high particulate removal, low density and its versatility; it can be used in mono and multi-media filters in both pressure and rapid gravity filter designs.
All our pumice filtration media has British Standard approval (BS EN 12906-1999) – Products used for treatment of water intended for human consumption’, European Standard approval (EN 12901/ 12902:1999) and UK Drinking Water Inspectorate approval. Additionally our pumice filtration media meets all the chemical and physical testing requirements for AWWA B-100 and DIN EN 12906.
We are currently in the process of seeking full SWCC (Saline Water Conversion Corporation) approval to further expand our Middle East Division.
