The wastewater you are ...

The wastewater you are treating from both sources are basically the same abet some subtle differences.  Yes hospital wastewater contains more pharmaceuticals but when mixed with the rest of the wastewater and faecal matter (yes folk crap in hospitals too) it is not a major problem as it will be very dilute.  The biggest difference could be the amount of rags (incontinence pads etc.) along with the cardboard urine bottles.  These should be separated from the waste stream but many just get dumped.  All these contribute to a large quantity of solids that clog up pumps etc.  In design terms the volumes attributed to the individual are different, with more water use in hospitals as opposed to residential systems.
