The mound on the right in the photo is still raw manure with about 25 percent of the moisture removed by a gravity separator. This pile is moved again to slowly drain until it can be removed, at significant annual cost, by a local service. Much of the manure is removed to a co-composting site for windrow processing. In full-scale operation, the EPTC Bioreactor eliminates the need for off-site composting.

This site uses an efficient FAN screw-press separator to reduce the moisture content to about 65 percent, optimum for the Bioreactor process. EPTC is now marketing its own improved screw-press type separator for this application.
