BLIVET - PACKAGE SEWAGE TREATMENT PLANT

Since 1985 BMS has been the leading Irish manufacturer of Package Sewage Treatment Plant, serving population equivalents (P.E.s) typically from 20 PE to 2,000 PE. Ongoing Research & Development has brought the BMS Blivet to the world stage, now in 25 countries worldwide and licensed to manufacture in Australia, Canada, India, New Zealand and South Africa.

Background

Since its inception, BMS has been a Research & Development led organisation. In 1986 it launched the BMS Aerotor as a unique, patented, combined active aeration & fixed film bio-reactor. From this successful product, the need to eliminate in-situ tank construction was identified. Further R & D led to the first BMS Blivet in 1989 - The first 'All in One' package sewage treatment concept.

Current Situation

By the end of 2003 nearly 300 Blivet units had been manufactured in the BMS facility in Longford, Ireland. Approximately 25% of these have been exported worldwide and over 40% of units, in the local market, go to Local Authorities and State Institutions.
