In the past two decades, there has been a remarkable development and improvement in wastewater technologies, driven by both necessity and stringent governmental regulations.

Today, municipalities and countries worldwide are recognizing the vital importance of recycling wastewater into clean drinking water. In certain regions like the Caribbean and other foreign nations, the wastewater to the drinking water industry is not merely a choice but a necessity.

To address our global needs and challenges, the recycling of wastewater to produce safe drinking water has become an everyday practice, empowered by cutting-edge technologies such as "Ultra-Filtration" and "Membrane Bio-Reactors" (MBR). These technologies continue to advance, offering much-needed solutions to the world's water scarcity issues. Moreover, due to stricter governmental requirements for wastewater recycling, the purity standards achieved through this process often surpass those of conventional water treatment methods. To foster global growth, it is crucial for professionals and consumers alike to acknowledge and embrace wastewater recycling whenever and wherever it is applicable to meet our evolving needs.

One of the key elements in the wastewater recycling process is the removal of contaminants, such as hydrogen sulfide gas, through advanced treatment methods. Hydrogen sulfide gas, a common byproduct of various industrial processes, can pose significant risks to water quality. Through technologies like Ultra-Filtration, this harmful gas can be effectively eliminated, ensuring the production of safe drinking water.

Another crucial aspect of wastewater treatment is addressing water turbidity. Turbidity refers to the cloudiness or haziness of water caused by the presence of suspended particles. By employing techniques like Membrane Bio-Reactors (MBR), wastewater can undergo thorough filtration, effectively removing suspended solids and improving water clarity. This ensures that the recycled water meets stringent purity standards and is suitable for drinking.

Extending the life of your ion exchange resin in boiler feed water applications

Did you know that when producing steam, it is most effectively accomplished by utilizing a decarbonation process? Decarbonation and Degasification is the most economical way to process fluent water pre-Ion exchange treatment through a vertically packed tower called a decarbonator, often called a degasifier.  This is the most economical method to remove carbon dioxide (CO2) and Hydrogen Sulfide (H2S) to prevent the formation of carbonic acid. Other corrosive conditions are Degasification and Decarbonation, which will extend the life of the ion exchange resin. If CO2 levels remain high in the inlet feed water to the ion exchange system, the resin beds, whether cation or anion, will require more frequent regeneration, and your chemical usage and cost will rise.

In industrial applications, it’s easy to overlook.

Often, there is insufficient focus on selecting the right decarbonation or degasification system to ensure that the process water treatment system performs at the highest optimal level. For water filtration, when the primary process is membrane filtration, often referred to as “reverse osmosis, " too little attention is given to properly removing CO2 from the process to lower the pH and adjust the alkalinity.

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.
