Maybe they have a model number. Let me know and I will give you an opinion.<img align="absmiddle" src="http://www.wef.org/TechnicalDiscussions/Skins/WEFTest2/Images/EmotIcons/Hehe.gif" border="0" title="Hehe">Mon, 29 Oct 2007 23:29:56 GMTJerryhttp://www.wef.org/TechnicalDiscussions/Topic7269-18-1.aspxDoes anyone have any experience with this system? Its a STEP collection system followed by sort of a recirculating sand filter system sans the sand filter - they use big plastic boxes with a 1/2" thick non-woven geotetile fabric which is draped over rods and hung packed close together in these plastic boxes - sort of a packed bed system. The septic tank effluent is sprayed over top of the packed material via spray nozzles- media stays unsubmerged and is dosed intermittently. Drainage goes back to recirculation tank. Iterested in any comments on permit parameters met (or not), reliability, ops cost, problems. Thanks!Sun, 28 Oct 2007 14:45:53 GMTbugwisperer
