Aco Marine, supplier of wastewater treatment technology to the maritime industry, has received Bureau Veritas (BV) type approval for its[ds_preview] new Aco Maripur NF sewage treatment system.
The BV tests confirm that Aco Marine’s next generation treatment plant meets the stringent performance requirements of IMO Resolution MEPC 227(64), which enters into force in January 2016.
Mark Beavis, Aco Marine’s managing director, said: »This is an important step forward in the continuing development of the Maripur product range. It confirms that the new treatment system goes beyond the new MEPC 227(64) standards to meet the revised discharge requirements, particularly Section 4.2.«
The revision requires vessels with more than twelve passengers operating in IMO designated »special areas« to reduce the phosphorous and nitrogen content of treated effluent. There is no mandate for this in the existing requirement.
Type-approval testing has verified that the Aco Maripur NF can reduce Coliform Bacteria to 17.5 count/100ml (standard is 100 count/100ml), TSS to 2.4mg/l (standard is 35mg/l), BOD to 7.3mg/l (standard is 25mg/l), and COD to 60mg/l (standard is 125mg/l), while nitrogen and phosphorous content is significantly below the mandated levels of 20mg/l and 1mg/l at 7.2mg/l and 0.3mg/l respectively.m
