The VermiDigest by BioFiltro

BIDA® beds consist of wood chips and/or shavings and are typically around 3 feet deep, which provides plenty of toasty insulation for the worms and biology. You will even see steam coming off the beds on a cold winter morning! BioFiltro even has a system on Antarctica treating wastewater from a Chilean air force base. “That system is treating domestic wastewater”, Sales Engineer, Sarah Haupt, explains. “Domestic wastewater—water from toilets, showers, kitchens—is relatively warm, and is our “cleanest” waste stream as far as wastewater constituents like BOD, TSS, & TN are concerned. In my opinion, BioFiltro’s worm farm at Royal Dairy in Washington is our most impressive example of cold weather tolerance because our worms are treating almost-freezing flush water from the cow stalls in the winter.” Freezing temperatures are a design consideration rather than a biological problem. Extreme cold means water could freeze and burst pipes, so BioFiltro installs an extra sump for water to drain into between BIDA irrigation cycles, and programs a “winter mode” button on the touch screen that controls our PLC [Programmable Logic Controller]. With this adaptation, water will automatically drain our irrigation lines fully during freezing temperatures, which prevents water from freezing inside pipes and causing damage.
