The Questor Centre (Applied Technology Unit) at Queen's University conducted a detailed study on the standard 6 population Bio-Klenze Treatment system. This study was carried out at Newtownbreda Municipal Treatment Works in Belfast, which serves the needs of 40,000 domestic dwellings. The tests were carried out in accordance with the British Standard BS 7781. The results outlined in below table satisfy the required demands of all regulatory authorities presiding over domestic wastewaters.
