Hamworthy, one of the world’s leading manufacturers of water treatment systems has become the first non-domestic sewage plant supplier to achieve CCS Type Approval, strengthening its position in the world’s largest shipbuilding nation.
The approval comes at a pivotal point in marine environmental legislation as new IMO Marpol Annex IV guidelines come into force requiring all vessels to be fitted with compliant sewage treatment plant.
In anticipation of the regulatory enforcement, in 2008 Hamworthy became one of the first companies to receive type approval in accordance with the IMO MEPC 159 (55) standard for its enhanced ST-C series. Hamworthy has now received a significant number of orders for sewage plants that conform to newly introduced international standards and its operations in China have already received multiple orders for CCS Type Approved plants, confirming domestic ship owner support for the initiative.
Existing MEPC 2(VI) sewage treatment plants do not conform to these standards. The new standard requires that total suspended solids must be less than 35mg/l, faecal coliform must be less than 100cfu/100ml, BOD5 less than 25mg/l and pH levels must be in the range of 6.0 to 8.5.
Eric Li, Engineering Manager at Hamworthy’s test and assembly plant in Suzhou said: “Achieving CCS Type Approval is a significant acknowledgement of the team work and cooperation between Hamworthy’s operations in the UK, Shanghai and Suzhou. The CCS Surveyor and the Director of the 704 Environmental & Engineering Centre commented positively on Hamworthy’s product performance and build quality whilst visiting the facility.”
Hamworthy’s ST-C enhanced sewage plant uses an extended aeration process which has been honed for marine application over four decades. The technology, which is fully compatible with gravity and vacuum collection systems, features an automatic control system for unattended operation and minimum maintenance and is available in a modular compact construction for retrofit applications. Hamworthy has also developed a range of advanced MBR (Membrane Bioreactor) treatments plants to enable ships to continue discharging black and grey water in especially sensitive waters, where regulations demand tighter controls.
Originally Type-Approved by Lloyd’s Register, the ST-C plant has also received EC Marine Equipment Directive (‘Wheelmark’) certification from the UK Maritime & Coastguard Agency.
