Catalogue excerpts

Waste, Oil & Fresh Water Management WÄRTSILÄ HAMWORTHY SMALL STC-13 SERIES SUPER TRIDENT SEWAGE TREATMENT PLANT Wärtsilä is the world’s leading manufacturer of marine sewage treatment systems. For over four decades the Wärtsilä Hamworthy Super Trident sewage treatment plant has been widely regarded as standard specification on all types of vessels and has been designed to meet all existing and future IMO standards. Plants installed on or after 1 January 2016 must meet the new IMO MEPC 227(64) effluent quality standards, which introduce a dilution compensation factor and designate the Baltic Sea as a “Special Area”. The Wärtsilä Hamworthy Super Trident sewage treatment plant is certified to meet these standards, which are more stringent than the current IMO MEPC 159(55) guidelines. The Wärtsilä Hamworthy Super Trident sewage treatment plant is a cost-effective and safe answer to disposal of waste at sea, maintaining the quality of the world’s oceans and complying with regulations for operational peace of mind. The small STC-13 sewage treatment plants are fully compatible with gravity and vacuum collection systems and uses the activated sludge system, which accelerates natural biological processes. Chemical chlorination and dechlorination are employed to produce a clean, safe, effluent suitable for discharging overboard. STANDARD FEATURES • IMO & MED certified • Single power supply input point • Minimal maintenance requirement • Solids handling centrifugal discharge pump • Chemical disinfection and dechlorination • Automatic control • Compact design OPTIONAL FEATURES • Fitted vacuum sewage collection equipment • Conditioning water flow meter • Standby compressor (mounted) • Standby discharge pump (mounted) • Maceration • Separate sewage feed system • Retrofit options available to aid installation
