The Need for Water Degasification in Pisciculture

Posted by Anthony DeLoach, President on Feb 11, 2020 9:36:29 AM

The need to remove harmful elements from water such as Hydrogen Sulfide and Carbon Dioxide from water in the pisciculture and aquaculture market is extremely important. In order to achieve maximum results, the industry utilizes a treatment technology called “Degasificationand controls the pH precisely to maximize results. When utilizing equipment such as the DeLoach Industries degasification systems the hydrogen sulfide and carbon dioxide levels can be removed to 99.999% ug/l.

Degasification for Pisciculture

To enhance and balance the water quality

in aquaculture and pisciculture operations, the industry is recognizing the benefits from utilizing a type of water treatment called “Forced Draft Degasification” to remove CO2 (Carbon Dioxide) and H2S (Hydrogen Sulfide) gases and oxidize other elements such as Iron or Magnesium.

 Removing these elements from the water process improves the quality of the water and aids in the balancing of the pH without the need for additional chemicals.

Aqua Farming

To enhance and control production and quality

of seafood that is grown and harvested the industry is increasing its focus on the construction of in house aquaculture fish farms commonly referred to as aqua farming. The most popular species of aqua farming continues to be salmon, tilapia, catfish, and carp. With the increase interest in the United States aqua farming facilities have been developing in parts of southern Florida where climate conditions and water conditions are favorable.

When considering several types of fish species to grow for harvest it is important to keep in mind the need to control the quality of the water. If the aqua farm is intended to utilize man made tanks they will depend upon a constant flow of incoming water. If the aqua farm is focusing on salmon than both the water quality and water temperature plays a major role on mortality rates and production yields of the operation.

Having water with too high of hydrogen sulfide, carbon dioxide, total Organic carbons, and even turbidity can increase mortality rates among the younger fish species and is especially critical to salmon.

Water Treatment

When planning and designing a man made on land aquaculture or pisciculture facility the most important key element is the quality of the water. For operations developing in Florida or the Caribbean it is important to remember that water quality varies in Florida and other states in the US and typically requires some type of water treatment. For fresh and salt water land based farms that utilize tanks located inside of a building the water needs to be treated and pure from any naturally occurring contaminants such as hydrogen sulfide (H2S), iron (Fe+), and even carbon dioxide (CO2).

The most cost effective way to treat incoming water for aquaculture farming and remove hydrogen sulfide, iron, and lower carbon dioxide is the use of a “degasification” tower. A degasification tower or degasifier is a piece of process equipment. Degasifiers can also be referred to as a “decarbonator” or “air stripper” or even “aeration tower”. The degasification tower is a vertical column designed to remove certain types of contaminants by “stripping” the molecules of converted gases and expelling them from the water as a gas. The science is based upon “Henry’s Law” and it relies upon the disproportionate varying vapor pressures of gases.

If the incoming raw water contains levels of sulfides or hydrogen sulfide gases it is recommended to remove the hydrogen sulfide to improve the water quality and reduce the risk of the development and formation of bacteria that can thrive on the Sulfur. In addition hydrogen sulfide is corrosive and will cause harm to other components within the process if left untreated. It is important to adjust the pH of the raw feed water prior to degasification to ensure full conversion of the sulfides into hydrogen sulfide gas (H2S) to enable the degasification process to perform and remove up to 99.99% of the harmful contaminants without adding additional chemicals. This saves money and improves quality of the product!
