The Term referred to as “Degasification” or "Decarbonation" and how they work

Relates to the process of the removal of suspended gas or solids that are converted to a gas-based upon certain criteria during water filtration, treatment, membrane filtration, or attempting to adjust pH.   When removing (CO2) the process is often referred to as “Decarbonation”, when removing (H2S) the process is often referred to as “Degasification”. 

Degasification is the most economical method for

the removal of Hydrogen Sulfide (H2S), Carbon Dioxide (CO2), and Oxygen (0₂) can all be removed by “Degasification”.  The other variables are the total inlet water flow rate, the inlet feed temperature of the water, the ambient air temperature, the inlet concentrations that can be expressed as parts per billion (ppb), parts per million (ppm) or Mg/l, and the desired effluent removal levels also expressed in the same method.  It is also important to fully understand the actual application and the use of the water to determine how critical maintaining critical levels are and what impact variations will create for the final use.   Understanding these variables will aid you in the design of the system and any additional redundant systems needed to assure full compliance with standards.

Do you need to remove or increase your reverse osmosis system's hydrogen sulfide removal efficiency?

The industrial water treatment market has many forms of water treatment processes. Most of us would agree that maintaining high water standards and quality requires using multiple treatment systems to achieve results.  Let’s face it, we do not win or get a “that a boy” when we design and build the best reverse osmosis system.

When we turn the brand-new water system on, the water has a "rotten egg odor." Yes, that is an embarrassing moment! 

The problem is we typically design around what we can see or read.  When was the last time you reviewed a water sample that provided details of how much-dissolved gas was in the water?  Most likely never.  A typical water treatment system may deploy reverse osmosis as the primary treatment method, and why true RO will remove particles that have size and weight (ions and molecules) typically defined as a certain size (micron), but RO does nothing to remove the dissolved gases that are already entrained within the water naturally or were created by adjusting the pH.

When it comes to removing hydrogen sulfide (H2S) from water through the process of degasification.

It is crucial to ensure that the pH of the water is properly adjusted prior to treatment. This step becomes more complex if you are not already pre-treating water for membrane filtration or softening. The reason behind this is that when the pH of water rises above 5.5, it becomes increasingly challenging to convert H2S or sulfides into a gaseous phase, which is necessary for their removal through the degasification process utilizing a degasifier.

At a pH of 7, the conversion rate drops significantly, and a standard degasification tower can only remove about 80-85% of hydrogen sulfide (H2S), leaving behind worrisome levels of this compound in the water. However, by lowering the pH to 5.5 (or at least a pH of 6), the removal efficiency dramatically increases to 99% in most cases. In situations where high water quality is demanded, such as in breweries or canneries, removal rates as high as 99.99% can be achieved by carefully adjusting the pH.

Leaving excessive amounts of hydrogen sulfide (H2S) or sulfur in the water can lead to various additional problems with water quality, including unpleasant taste and odor. Moreover, it can cause fouling and corrosion of the primary equipment and even the facilities themselves. The negative consequences of inadequate hydrogen sulfide removal underline the importance of addressing this issue effectively.

Maximizing Efficiency and Flow: Industrial Water Treatment with Degasification Systems

Industrial water treatment plays a critical role in maintaining water quality and ensuring the efficient operation of various processes. Degasification and decarbonation systems are essential components of such treatment methods. These systems effectively remove gases from the water, improving its quality and minimizing the risk of corrosion. However, when designing and installing degasification or decarbonation towers, it is important to consider hydraulic flow and system design. This blog post will explore the significance of proper hydraulic fundamentals in optimizing degasification systems, avoiding common pitfalls, and ensuring smooth water flow.

Optimizing Hydraulic Flow for Degasification Systems

Leveraging elevations can greatly benefit hydraulic flow when incorporating a degasification or decarbonation tower into an industrial water treatment system. For example, placing the tower on top of a large clear well or on a structural platform adjacent to the tank can optimize water movement. This strategic placement takes advantage of gravitational forces and enhances hydraulic efficiency.

However, applying sound hydraulic principles during the system design phase is crucial to prevent costly issues. Design professionals typically consider factors such as the size of the effluent fitting or pipe diameter and base their design on the length of the run and elevation. Failing to account for these factors can lead to hydraulic turbulence and improper water flow.

Preventing Tower Flooding and Hydraulic Turbulence

 

Improperly designed tower drainage systems can result in flow issues, leading to tower flooding. This occurs when water begins to vortex from the bottom of the tower due to a straight laminar pipe configuration. Vortex breakers such as the DI-VB100 series or other devices must be integrated into the tower design to avoid this. These breakers disrupt the vortex formation and promote smooth water flow.

Ensuring Optimal Performance and Efficiency

When designing and installing a water treatment system, it is crucial to consider the hydraulic conditions that may arise when incorporating a degasification or aeration tower into the process. Hydraulic conditions can vary from one job to another, and the conditions created by a degasification tower are no exception. To optimize the performance and efficiency of the system, it is necessary to address potential issues such as vortex formation, increased suction on the effluent line, and water flow restrictions. In this blog post, we will explore the importance of incorporating vortex breakers, air relief valves, and anti-siphon valves to prevent hydraulic air locks and ensure the smooth operation of the degasification tower.

Preventing Hydraulic Air Locks in Degasification Towers

When a degasification tower is installed in a water treatment system, it is susceptible to hydraulic conditions that can lead to airlocks. These conditions primarily arise when the effluent drain line drops straight down for a significant distance. The resulting vortex effect causes the water to swirl, drawing air down the center and restricting the drainage of the tower. Additionally, the increased hydraulic flow and distance can create heightened suction on the effluent line, potentially causing flooding inside the degasification tower.

To avoid these issues, it is crucial to install vortex breakers inside degasification towers. Vortex breakers are specifically designed to disrupt the vortex formation, allowing for smooth water flow and preventing air locks. By strategically locating air relief valves and anti-siphon valves along the finish effluent pipeline of treated water, the risk of hydraulic air locks can be further minimized. These valves serve to release trapped air and prevent siphoning, ensuring optimal performance and preventing potential damage to the system.

Addressing Other Considerations: Decarbonation, Degasification, and Odor Control Scrubbers

Apart from preventing hydraulic airlocks, there are additional considerations in water treatment systems that warrant attention. Decarbonation is a process that removes carbon dioxide from water, particularly important in applications where low alkalinity and pH control are essential. Degasification, on the other hand, involves removing dissolved gases from water, often through the introduction of air or other methods like vacuum stripping or membrane degasification.

In certain cases, water treatment systems may also require odor-control scrubbers. These scrubbers effectively remove unpleasant odors caused by chemical reactions or the presence of certain compounds. By employing various techniques such as chemical adsorption or biological treatments, odor control scrubbers ensure the final treated water meets the desired olfactory standards.

When designing and installing a water treatment system, careful consideration must be given to the hydraulic conditions that may arise within a degasification or aeration tower. Incorporating vortex breakers, air relief valves, and anti-siphon valves into the system is crucial to prevent hydraulic air locks and ensure smooth operation. Furthermore, controlling alkalinity and pH, addressing water turbidity, and implementing decarbonation, degasification, and odor control measures are vital to optimizing the performance and efficiency of the water treatment system. By consulting professionals in the field, such as DeLoach Industries Inc., you can gain valuable insights and expertise to tailor your water treatment system to your specific needs and requirements.

What to consider when designing your degasification or Decarbonation water treatment system.

 

When designing a water treatment system the need for aeration or degasification is quite common, as it is the most cost-effective way to treat water and obtain the highest results. For the oxidation of iron, or the removal of Carbon Dioxide (CO2) or Hydrogen Sulfide (H2S), aeration and degasification remain the most efficient methods to treat potable and industrial water. So how do you know if you should select a round or a square aerator or degasifier, and when is one more appropriate than the other? The selection of a square-shaped aeration or degasification tower always provides the owner with more! Why? Well, it’s simple, first think about a 6 ft. diameter round tower and how much square footage is available for use and how much space it takes up. A 6-ft. diameter equals 28.26 square feet of area, whereas a 6-foot square tower provides 36 square feet of area. That’s over 25% more surface area than in the round tower. Both tower designs take up the same area on the ground when you consider the installation space needed for the “footprint”.
