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 oxygen rich water will provide just the right current for good muscle tone while distributing new water evenly throughout the tank.
The Aquacare radial flow separator is a 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 specifies Microscreen Filters as a highly efficient solids removal filter for aquaculture applications. It is effective for fine and soft solids removal. The filter provides high capacity single stage filtration to gently separate soft solids with minimal head loss. The grid supported micro screen removes larger and fine particles.
Aquacare designs and supplies five different types of Aquaculture Biofilters.
OxyFlow® is a cost efficient oxygen dissolving unit process device; operating at 0.3 bar vs. Speece Cone at 3 bar. This differential in pressure represents a significant cost savings on power bills.
Aquacare designs and supplies reliable energy-efficient site and purpose specific pumping systems. One preferred combination that Aquacare supplies is the Carry Stainless Steel Axial-Flow Submersible Pump combined with Yaskawa Variable Frequency Drives (VFD)
Aquacare builds control systems to monitor and control all critical parameters such as temperature, flow, tank levels, oxygen levels, pumps and other critical parameters with multiple built in configurable alarms. The systems provide the information necessary for the efficient management of the facility.
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.
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.
Based on our experience and utilizing the equipment, technology and components available from Aquacare and its associates, Aquacare is able to offer complete, modular, prefabricated fish farms that are manufactured in the United States and can be economically shipped to any location in the world to be assembled by local labor under the supervision of Aquacare construction specialists.
