What Is Water Turbidity?

Posted by Anthony DeLoach, President on Mar 18, 2022 1:05:00 PM

Water turbidity refers to how transparent or translucent the water is when examining or testing it for any given use.

Water turbidity can impact food and beverage, municipal, industrial, and aquaculture operations. Turbidity is caused by suspended or dissolved particles in the water that scatter light which causes the water to appear cloudy or even murky.

Different types of particles can cause turbidity, and they include sediments such as silts and clay, very fine inorganic or organic matter, algae or soluble colored organic compounds, and microscopic organisms. Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit. The EPA requires a turbidity level no higher than 0.3 NTU in the USA, and if a member of the partnership of safe drinking water, then the level must not exceed 0.1 NTU.

High turbidity can create habitats for other harmful elements, such as bacteria or metals, that can accumulate onto the particles. This increases the health risk for a potable water system. In aquaculture operations, increased turbidity from silts and sediments can be harmful and detrimental to marine life, so it must be removed to safe levels. For the food and beverage industry, the impact of high turbidity can be both a safety concern and a visual and noticeable quality concern because if the turbidity is high, it can alter the physical look of the final product, for example, a distillery.

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.

pH control with water degasification in water treatment is very important for the aquaculture and the pisciculture market. In addition, there are a host of other organic and inorganic elements found in water both naturally occurring and manmade that require removal during some part of the water treatment process and pH plays a significant role on the effectiveness of the treatment process.

Every application of degasification depends on pH adjustment to maximize results. As an example, the treatment of water may require the removal of hydrogen sulfide (H2S) to protect the species during the growth period. Hydrogen sulfide can be removed either as a “free” gas or requires the conversion of sulfides into (H2S) as a gas they you will quite often also see the need to adjust pH of the water chemistry to maximize both the removal and the conversion to increase the efficiency of the equipment being utilized to remove the hydrogen sulfide such as a degasification tower or commonly called a degasifier.

Relationship of Water Degasification and Decarbonation and pH

The need for pH control with water degasification and decarbonation in water treatment includes almost every industry and includes;

The need for pH control with water degasification and decarbonation in water treatment includes almost every industry and includes; Aquaculture, food and beverage, industrial, municipal, and even pisciculture.  In some water treatment applications, harmful gases such as Hydrogen Sulfide (H2S) are removed, while in other applications, Carbon Dioxide (CO2) or a combination of both. In addition, there's a host of other organic and inorganic elements found in water, both naturally occurring and manmade, that require removal during some part of the water treatment process.  

In almost every application of degasification or decarbonation, you will hear or see the term pH used either by need or by the result.  If, as an example, the water treatment application requires the removal of Hydrogen Sulfide (H2S) to be removed either as “free” gas or requires the conversion of Sulfides into (H2S) gas. You will often also see the need to adjust the pH of the water chemistry to maximize both the removal and the conversion to increase the efficiency of the equipment being utilized to remove the hydrogen sulfide, such as a degasification tower or commonly called a degasifier.

So, what is pH?

Water pH is a term used to describe whether or not the water is “acidic” or “basic.”  pH ranges in water can be from 0-14.  0 is the most acidic, and 14 is at the far end and is the most basic, leaving “7” as the neutral state.  A pH of 7 is neither acidic nor basic. So, what causes pH to be acidic?  In nature, the most common cause of a low acidic pH in water is Carbon Dioxide (CO2) which occurs naturally when photosynthesis, decomposition, or respiration occurs in nature.  The increase in CO2 causes an increase in ions, producing a lower pH in a simplified explanation.

How does pH play such a significant role in degasification and decarbonation? 

As mentioned above in the example of the removal of certain harmful elements such as sulfides, sulfates, and free H2S hydrogen sulfide gases, to maximize the removal from water utilizing a degasification tower, it is essential to maintain as close to a pH of 5 as possible.  When the pH rises above 5, the ability to convert and strip the free H2S gas from the water diminishes.  When a degasification tower operates within this specific range and if it has been designed with the higher efficient distribution systems such as the ones utilized by DeLoach Industries, removal efficiencies of 99.999%- 100% can be achieved.   If the pH rises to seven or above, the removal process becomes much more complex, and typically, you will have much lower results.  The pH adjustment during the water treatment process is typically accomplished by adding commercially available acid, such as “sulphuric acid,” one of the most common in the municipal and food and beverage industry.

Degasification for Pisciculture

Posted by Anthony DeLoach, President on Jul 23, 2019 11:03:53 AM

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. This also reduces the risk of unnecessary and preventable loss of life to your aqua farming  project.  Keeping the ph at the proper level will enable a good healthy environment and will prevent further problems that may occur due to the ph is not kept in a stable state.

Not all degasification towers are equal!

The market has seen an influx of low efficiency performance systems which why they may offer a low capital entry point for a customer they fall short on providing the overall quality enhancements a properly design degasification tower provides. Utilizing low efficient perforated trays with natural updraft will result in low removal efficiencies of CO2 and H2S gases.

There are additional benefits that are achieved when a properly designed and sized degasification tower is selected for aquaculture water enhancement which include the ability to remove excess heat from the water and stabilize a temperature from the effluent of the tower. In order for your system to maintain its efficiency it is important to design the proper tower for your needs. In addition, the oxidation of iron with enhance enrichment of O3 (Oxygen) and complete conversion and removal of CaCO3 (Calcium- Carbonate). A properly sized degasification tower or Decarbonation tower if your goal is to only remove CO2 will utilize a loose fill media packing bed, a header lateral distribution system with nozzles, media support plates, de-mister, and a forced draft type blower capable of overcoming the required static pressure.

Aqua Farming

Posted by Anthony DeLoach, President on Sep 11, 2018 9:09:00 AM

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.

Having high levels of metals

such as Iron that is identified as either “ferric” (Fe-) or “ferrous” (FE+2) and is naturally occurring within the Florida waters and other parts of the US will cause significant damage to young salmon species because the metal accumulates within the gills of the fish causing suffocation. Other metals are also detrimental to fish including copper, aluminum, arsenic, cadmium, chromium, Lead, manganese, mercury just to name a few and the water quality must be evaluated and tested in the early stages of design to anticipate the required types of process systems needed.

Water Treatment in Aquaculture

Posted by Anthony DeLoach, President on Sep 6, 2018 10:11:28 AM

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!
