Aquacare controlled environment aquaculture systems

by Henning Gatz, Aquacare, USA

Aquacare Environment Inc was established in 1987 with the purpose of supplying cost effective industrial scale equipment to the growing aquaculture industry worldwide.

The company began by marketing glass-fused-to-steel bolt together tank kits to the emerging aquaculture industry and has since grown into an integrator of complete systems. Working closely with JLH Consulting Inc to provide leading edge bio-plans and system designs, Aquacare is growing along with the industry.
 


Aquacare has partnered with JLH Consulting with the goal of reducing capital costs, improving the growing environment and controlling operating costs of farms. The use of pre-engineered and pre-fabricated system components helps to standardise farm designs and lower the installed cost of fish farm equipment. Aquacare and JLH have worked to reduce pumping heads and oxygenation cost to help their clients operate as cost effectively as possible.

Distribution and OEM relationships with specialised manufacturers, allow Aquacare to specify and ship the best value in components available to build and operate a successful fish farm. Adapting equipment manufactured for a larger market, to the specific needs of aquaculture, provides an economy of scale unique to this industry.

Tanks
Circular tanks are becoming standard in aquaculture because of their cost per cubic meter of volume, inherent self-cleaning nature and long life-cycle. Tanks are also becoming larger and, thus, cost- effective construction methods are needed. For tanks 100 cubic meters and larger, it is hard to find a more cost-effective and long-lasting tank system than the glass-fused-to-steel bolt-together tank developed over seventy years ago for use as animal feed and manure storage tanks and silos. Today, this tank system is in use in thousands of applications worldwide, ranging from water treatment and storage, to aquaculture tanks.

In addition to circular tanks, Aquacare also supplies MxCell Raceway® tanks. These are plug-flow raceways that are divided into a series of hydraulically separated cells that act like circular tanks, providing the self-cleaning environment that traditional raceways cannot.

Solids removal
Self-cleaning drum Microscreen filters, with fine mesh screens, are the first line solids removal mechanism used in modern fish farms. It is important to remove these solids in a gentle way, using gravity flow, rather than pumped flow, that would macerate the solids and make them more difficult to remove.
