You *must* have something that will kill bacteria (or promote the use of good bacteria). Around 35% of the dry weight of faeces is bacteria (variable water content). You do not want them to multiply - as the tank is sealed, then it's possible for the oxygen to be slowly removed by some bacteria, then allowing the more nasty anaerobes to start growing - which will lead to serious unwanted gas production, and may well be hazardous.
