The Ecolo-filter ACF from TEAMCO separates liquids and solids by filtering the whole septic tank at once. It can pump 10 to 12 septic tanks before discharging, and is fully automated and operated by remote control. The automated pneumatic valve system drives all solids into the tank and the filtered liquid returns directly, using the same vacuum hose, to the septic tank by a stainless steel centrifugal pump. This unit is equipped with a 1,600 cfm air-injection blower vacuum system, which can reach up to 27 Hg. Tanks can be manufactured in aluminum or steel. 819/358-6808; www.teamco.ca.
