In most cases, there will be two or more separate holding tanks on board a vessel, containing either blackwater or greywater or both as a sewage mix. Untreated sewage has to be pumped from holding tanks to the sewage treatment plant for processing. In addition, there may be the requirement to be able to transfer sewage between holding tanks. Furthermore, there should be the option to discharge untreated sewage ashore or to pump it overboard, if permitted.
HAMANN sewage treatment plants are always fed from a single holding tank, the sewage mixing tank. Provision needs to be made for the contents of the blackwater and greywater holding tanks not connected to the sewage treatment plant directly to be fed into the sewage mixing tank. Furthermore, HAMANN STPs are designed to treat a mixture of sewage containing both blackwater and greywater. Consequently, a way to channel greywater from dedicated holding tanks into the sewage mixing tank is required.
HAMANN sewage transfer management systems take over all these tasks automatically. The system software controls all transfers to the sewage mixing tank or another holding tank. This ensures that available tank capacities are used in the best possible way, fill levels of all tanks are optimally coordinated, overly long storage times in some holding tanks are avoided and that a mixture of black water and grey water is available in the sewage mixing tank for feeding into the sewage treatment plant.
