LectraSan/ElectroScan systems macerate the sewage then treat it with a chlorine compound made from electrically breaking down sea water. The resultant effluent is a sludge that has all the bad guys killed by the chlorine compound. The chlorine compound returns to it's original composition, seawater. You are pumping harmless
fish food overboard with no additional compounds. It is as safe, if not safer than city sewage systems but does not meet the particulate standards for
drinking water.
The EcoNazi's are now saying, Lectra/Electro devices must be banned because of the particulate matter. The truth is every municipal sewage system in the country dumps more completely untreated sewage in to surrounding waters every year because of weather/equipment failure than the entire
boating community could do in a century if not a millenium. In short
boats supply an insignificant amount that does not effect the
environment in any measurable way. Non point source pollution (your lawn among other things) are the real problem in pollution. It's not pollution of harmful virii or bacteria but nutrients that find that mess up the balance of the ecosystem.
In any case, almost all harmful organisms are rendered null and void after very short immersion in
salt water. NDZ's in
salt water, in almost cases, are a politcal ploy to make the local politicians look like they care, not a
health issue. Fresh water is another story as the harmful bugs can and do survive. Type 1 and 2 sewage treatment systems serve the necessary sanitation functions in fresh water as long as the manufacturers specifications are followed, typically adding
salt to the effluent.
In short, we don't need to turn our
boats into floating outhouses if we'd all install type 1 or 2 treatment systems.
