NATURE ADORES A VACUUM TOILET
The use of vacuum technology in shipboard sanitary installations has become standard for many shipyards, fleet operators and navies. The author explains how these installations use a vacuum, instead of water and gravity, to move black water from toilets--and sometimes waste water, as well--to a central point for collection, treatment or discharge. He discusses the advantages of the vacuum installations, such as the simplication of sewage pipe routing and the reduction of water requirements by a factor of ten with an accompanying reduction in the volume of retained sewage. It is noted that passenger ship operators, in particular, find the low-noise level 'silent' vacuum toilet, introduced in 1987, to be very desirable equipment. Diagrams of an Evac toilet and a central collecting unit are shown.
