The BMS Dual Media Sand Filter is a compact Duty/Standby Filter system specifically designed for the tertiary treatment of effluent discharges from sewage treatment plants. The filter housing is constructed in GRP and comes fully assembled. It is suitable for installation at new or existing wastewater treatment plants.
Since its inception, BMS has been a Research & Development led organisation. Our package Dual Media Sand Filter was produced in response to customer requests for a compact package tertiary effluent treatment system. The Sand Filter produces high-quality effluent without the need for percolation, requires very low maintenance and has a small footprint. It is suitable for installation in conjunction with new sewage treatment plants or for retro-fitting to existing sewage treatment plants to improve effluent quality. The Sand Filter can reduce both BOD and Suspended Solids to below 5 mg/l before discharge. The Sand Filter is manufactured under BMS ISO 9001:2008 Quality Management System, in Longford, Ireland. It is a perfect compliment to the BMS Blivet, the worlds most compact ‘all in one’ sewage treatment system.

* The filter media can be adjusted to give lower flows and higher effluent standards.
** For ease of construction the civil works consist of a flat base support slab (1.2m x 1.2m) in 20N reinforced concrete and the placing of the filter thereon. The backwash sump requires a 1.8m diameter concrete base slab.
*** SS refers to Suspended Solids & BOD refers to Biochemical Oxygen Demand.
