Peggie, I have a Raritan chlorinator macerator, that takes a clorox bottle. it looks like a Purisan unit. It is new in the box. do you know anything about these?

Good Lord...it has to be at least 35 years old...they were discontinued in the late '70s. In fact, that macerator/chlorinator was the first product Raritan ever made--the one that founded the company in the '60s. Wilcox-Crittenden also made one...and there were a few others too.

Macerator-chlorinators were the forerunners of Type I MSDs, made in the '60s and '70s--and also the forerunners of macerating electric toilets--but were all discontinued after the Federal Water Pollution Act ("Clean Water Act") of 1977 was enacted, creating marine sanitation laws. 'Cuz they were never CG approved....they didn't macerate any more than a macerating toilet, and the amount of chlorine/time the waste was exposed to it didn't even come close to killing enough bacteria to meet Type I standards...they were just a "feel good" device that was better than nothing...the Crown Head with the chemical reservoir does as much.

So I hate to break it to you, Ed...but a macerator/chlorinator is worthless as anything but a museum piece. In fact, since yours is still new-in-box, you might ask Raritan if they want it for theirs.

Where'd you get it, btw?

Peggie's correct; you've got a museum piece there.  The Electro-Chemical Chlorinator went out of production in 1976, four years before the Marine Sanitation Laws were implemented (in 1980).  It had been submitted to the Coast Guard for possible certification somewhere around 1974.  Certification was denied, as it didn't macerate the particles to a small enough size, and there was no guarantee that the user would actually have Chlorox in the Chlorox bottle.  They wanted to make it as foolproof (and work-around-proof) as possible.  So _base_d on that, certification was denied.  At approximately the same time, the Lectra/San did gain certification and as a result, the Electro-Chemical Chlorinator was dropped from production.
