ACO Marine Data sheet ACO Clarimar® MF Sewage Treatment Plants IMO MEPC 227 (64) IMO has adopted RESOLUTION MEPC 227(64) with revised guidelines for effluent standards and performance test procedures for sewage plants. These guidelines, adopted in October 2012, which supersede resolution MEPC 159 (55), include the standards of section §4.2 that specifically apply to passenger ships operating in MARPOL Annex IV special areas and which intend to discharge treated sewage effluent into the sea.The ACO Clarimar® range of sewage treatment plants are fully certified by Bureau Veritas (BV) to IMO MEPC 227 (64) [excluding §4.2]. Manufacturing, Test and Quality Management are certified to ISO9001:2009/ ISO9001:2008 and EC MED Module D. ACO Clarimar MF - ACO-MF ´Bio-Sword´ Filtration Technology The ACO Clarimar MF biological sewage treatment plant incorporates ACO-MF filtration technology eliminating the requirement for settling and chlorination stages. Disinfection of the treated effluent is by in-line mounted UV lamp with no requirement for chamicals in any part of the ACO MF process. n Manufactured entirely in the EU from high performance materials which, unlike coated black steel, are completely corrosion resistant and light weight n Type Approved to IMO and EC MED Module ‘B’ n Lowest running costs of any sewage treatment plant on the market with minimal operator intervention n Compatible with both gravity and vacuum systems n Modular design concept for simple installation requiring only one power connection n Simple automated operation requires minimal operator intervention and maintenance Process description DILUTION INLET EMERGENCY OVERFLOW SEPARATION TANK SAMPLE COCK ACO - MF "Bio Sword" MAINTENANCE LEVEL EFFLUENT PUMP Clean water from the mixed liquor in the sword chamber is drawn through the ACO-MF ‘bio-sword’ by the effluent discharge pump (an optional standby unit is available) and discharged either directly overboard or alternatively to be recycled back into ship’s storage for re-use as technical fresh water for all non-potable requirements such as toilet flushing, deck washing or even laundry applications. DESLUDGING PUMP Sewage and waste water enters into the main activation stage where it is thoroughly mixed and aerated by fine bubble aeration membrane elements. Mounted blower(s) (an optional standby unit is available) provide air to the aeration elements whose innovative design allows quick and easy removal for cleaning. Aerobic bacteria and microorganisms, naturally present within the waste material, break down the organic matter into mostly carbon dioxide, water and inert non-organic material. Throughout the process the bacteria cells continue to reproduce new organisms to sustain the biological process. High efficiency of purification is ensured by the use of biocarrier. Disinfection of outlet treated water is carried out by the unit mounted UV lamp. A separate Discharge & Maintenance Pump (DMP) provides the higher capacity de-sludge and emptying requirement. Treated effluent water is colourless and odourless. Discharge is controlled by level control connected to the effluent di
