Cave Spring Cellars, Ontario Canada
In October 2015, a full scale system using four BioGill® bioreactors was installed by EcoEthic Inc. – a Canadian wastewater specialist company and BioGill® distributor.
As a first step, the winery set up a pilot project which saw BOD drop from as high as 6,000 mg/L to just 48 mg/L in 22 hours, well below the required threshold.
Wastewater flows down from the crush pad into two consecutive settling tanks. From there the effluent moves to a large balancing tank (30,000L) where the composition is balanced for easier filtration. Effluent then goes into the processing tank where it is circulated into the BioGill® units. The effluent is delivered to the top of the BioGill® units, then gravity fed over and down the nano ceramic gills.
BioGill® technology harnesses microorganisms, nature’s best recyclers and decomposers, to remove the organic material (BOD) in the wastewater. The microbes grow on the gills, effectively digesting the BOD-producing organic materials.
The BioGill® system has lowered the BOD in the winery wastewater by up to 99%. Prior to treatment, the BOD from non-vintage loads can be up to 9,645 mg/L. Following a 22 hour treatment cycle, the BOD has been reduced to 101 mg/L.
In June 2016, Cave Spring Cellars became Ontario’s first certified sustainable winery for its wastewater treatment, waste management and energy savings initiatives.
