I am looking to fit a sewage treatment plant to our 34m motor yacht (12 guests / 6 crew). Been doing some reasearch and have that Hamman have a mini system but have told us that their system is suitable for only 10 / 12 persons max.

There big system is not cheap by any means and would like to investigate an alternative brand. Boat is based in Med.

Any feedback positive or negitive would be great.... When going to spend large ammonts of owners cash would like to make sure am buying the correct system.

Regards

Hi Tim, installed many seawage systems , but now we use the Bio-Filt system from Rochem its good to have a look at it , these systems are now almost standard at the feadships we build look for information at there website www.rochem.co.uk regards Fokke Willem

The benefit of Hamann is that every one knows the system in and out being the industry standard. Rochem is very good but HUGELY expensive, needs a properly trained engineer to use it a large biowaste tank and is very sensitive to what goes in the waste system. Unless you're going to alaska stick with Hamann.

Hamann system works fine. Was initially wired to operate automatically but I prefer to operate the system manually, this practice prolongs component life and reduces chlorine costs. Routine cleaning and flushing of the device seems to help as well.

Good Morning Engineers, Hi, I'm a new Y3 to Yachting and just completed my first handover, so this is my first big question! Have you looked at MEPC 55/23 and where we stand if still operating the Hamann HL-Cont (1cm/h) compact Mini System. Basicaly all i can see that from 1st Jan 2010 nothing from this system should be pumped over board unless: To Shore or +12 miles from land. So how do you work with this system when the holding tank is only 5.3 m³ and last about 6 hours until full? Any thoughts? Regards David

One thing that is very helpful in sewerage treatment is to pump air through the black tank continuously using

a centrifugal pump and educator or a blower this keeps the aerobic bacteria alive and aids enormously in

pretreatment of sewerage and it is an inexpensive thing to do.  RD
