Fraser have access to collective world-wide experience in designing, supplying and servicing sewage treatment systems for the marine environment. Using the latest technologies allows us to tailor-make systems to suit every individual requirement and provide both environmentally sustainable and economically efficient solutions. The two main types of sewage treatment plants we offer are biological and physicochemical.  The key features of EVAC’s ORCA III: designed for treatment of both black and grey water fulfils IMO MEPC 159(55) requirements low maintenance compact footprint, ideal for retrofitting to existing vessels fully automatic in normal operation. The treatment is not based on an activated sludge process, therefore the ORCA III is easy to operate and is almost immediately operational after start-up. The shut-down process is also short and simple. H.I.Fraser also supply spare parts and service all EVAC equipment. Check the Online Catalogue or contact us.
