  • Aquacare - Multi-cell Biofilter for Fish Farming

    Aquacare - Multi-cell Biofilter for Fish Farming

    Multi-cell biofilters have automatic carbon source dosing. Bacteria are first starved of oxygen, then with the addition of supplemental carbon source remove the O from NO3. Carbon addition is controlled using an ORP sensor feedback loop.

  • Aquacare - Fish Farming Tanks

    Aquacare - Fish Farming Tanks

    There has been a significant shift towards round tanks for fish rearing. Properly designed round tanks with a central drain, moderately sloped floor and proper inlet piping take advantage of gravitational and centrifugal forces to keep themselves clean. The water moving in a circular flow will carry the solids to the central drain, from where they can be piped away for separation and re-use or disposal. With a properly designed inlet system, the...

    Aquacare - Radial Flow Separator for Fish Farms

    The Aquacare radial flow separator is a aquaculture device for particle removal from fish farm effluent flows. The radial flow separator is also very effective in removing settleable solids such as sand and grit from farm supply flows. This simple, proven device is in use on fish farms in the United States, Canada and Norway.

  • Aquacare - Waste-to-Energy Systems from Fish Farming

    Aquacare - Waste-to-Energy Systems from Fish Farming

    Producing heat and electricity from fish farm by-products; Ecology teaches us that in natural systems there is no waste, only wasted matter. Under this principle, everything is food for something else. Intensive animal feeding operations create by-products that can be used for other valuable purposes. These range from fertilizer products to energy products. The feasibility or opportunity to re-use by-products is best explored on a case by case basis...

  • Aquacare - Wetland Fish Farm Effluent Treatment Systems

    Aquacare - Wetland Fish Farm Effluent Treatment Systems

    Even recirculating fish farms produce some effluent water, generally loaded with nutrients that need to be stabilized before the water can be discharged. If a hydroponic system is attached to the fish farm, the nutrients can be directly utilized to produce a supplemental crop. In those cases where a supplemental hydroponic operation is not feasible or possible, the nutrient loaded effluent water can be managed by implementing an Ecological Constructed...
