With a single monobloc unit integrating a primary tank and a biofilter, the Ecoflo PACK from Premier Tech Aqua is designed to be suitable for both primary and secondary homes with a 500 or 600 gpd capacity. The NSF-certified system is based on a proven compact filter technology that treats wastewater without energy and retains pollutants, thanks to 100 percent organic filtering media. It offers ease of maintenance and all the benefits of a recyclable filtering media that can be accessed via the lid at the end of its useful life. It is available in ready-to-use rotomolded polyethylene shells or as a kit to be integrated into concrete tanks, reducing transport logistics and wait time. 604/346-8199; www.premiertechaqua.com.
