HAMANN sewage treatment plants (STP), or marine sanitation devices (MSD) and advanced wastewater treatment systems (AWTS) are designed to process both blackwater and greywater as a sewage mixture.

Full Answer
What is black water?
HAMANN AG defines blackwater as follows: Drainage containing faecal matter, e.g. from toilets. Drainage from medical premises if present. Black water is therefore a subcategory of sewerage. The terms blackwater and sewage are often used synonymously, as they both contain faecal matter.
Why is grease trap important?
However, due to the high fat content in galley water, separate treatment in a grease trap is important not only for the performance of sewage treatment plants, but e.g. for the entire piping system for sewage and greywater on board, which can otherwise quickly become clogged by fat deposits.
