Forced Draft Degasification Pre and Post Cation And Anion Exchange

Posted by Anthony DeLoach, President on Oct 23, 2018 7:49:53 AM

In the production and purification of water for industry there are many types of different processes available to remove harmful minerals and gases from the water stream but the most effective process and most cost effective from both a capital investment and operational cost is a “Forced Draft Degasification System” (Degasifier).

Degasification is used in a wide range of water processes

for industrial and municipal applications which extend from the production of chemicals to the production of semiconductors and in all applications the need to remove contaminants from the water and dissolved gases is key to achieving the end results needed in the industrial water process. Water from the ground often contains elements such as calcium carbonate, manganese, iron, salts, hydrogen sulfide, and sulfur just to name a few of the basic contaminants and these naturally occurring elements can cause serious damage and consequences to process equipment such as boiler systems, piping, membranes, and cation and anion exchange resins used in the demineralization process.

Calcium carbonate can dissolve in water under certain pH ranges forming carbonic acid and releasing carbon dioxide (CO2) gases. These gases are not only very corrosive to equipment like boiler feed systems and boiler tubes but also attack the actual resin beds found in cation and anion softening and demineralization system causing an increase in regeneration and chemical consumption and resin bed replacement.

By incorporating a Force Draft Degasification system you can remove dissolved gasses

like CO2 and hydrogen sulfide (H2S) to as low as 99.999% and improve the cation and anion system performance, extend the resin bed life, and lower the operating cost of the water treatment process.

Quite often Forced Draft Degasification is utilized “post” treatment to also remove newly formed dissolved gases prior to entering the boiler feed system to prevent corrosion damage within the tubes and feed system and pumps. These gases are easily removed with the forced draft degasifier at a much lower cost than chemical additives or liquid cell degasification that requires higher capital cost and much higher operating cost.

Odor Control with Artificial Intelligence

Posted by Anthony DeLoach, President on Aug 14, 2018 8:55:00 AM

Would it be possible for our odor control scrubbers to communicate with us and tell us when there are problems? Or when they need service? With the new technological revolution, we are now into this is quickly becoming a reality. DeLoach Industries is rapidly changing how water treatment and odor control and air emissions are treated with new advancements in artificial intelligence and integration into proven technologies.

Most operators will tell you that to keep and maintain an odor control system whether its Biological Vs. chemical can be quite challenging depending on the type and source of the off gas to be treated and depending on the type of chemical reagents being utilized such as acid or caustic solutions. When odor control systems such as a biological scrubber are met with a varying flow rates, corrosive gases, or spiking concentrations an odor control system can be daunting to keep in balance and operating efficiency. But what if they could think or communicate with other devices or even operators for themselves? What if they could make corrections in caustic feed rates because of ammonia (NH3) concentration spikes, order chemicals like caustic or acid for pH control, and even inform us when they anticipate a problem for either the odor control scrubber or another critical component that it depends upon? That time has now arrived that’s to DeLoach Industries new advancements to their equipment systems.

Industrial Boiler Feed Water For Steam

Posted by Anthony DeLoach, President on Jul 31, 2018 10:01:00 AM

In the USA market alone it is estimated the manufacturing industry consumes over 400 millions of gallons per day (MGD) of water to produce steam. Approximately 60 millions of gallons per day (MGD) of water is sent to the blow down drains in manufacturing. Another approximate 300 millions of gallons per day (MGD) of steam is consumed for direct injection. All this steam required in manufacturing shares the same common need, “water”. But not only water but “purified and treated” water is needed. For without the treatment process US manufacturers would face constant shut downs and increased capital spending driving their cost of goods through the roof. One form of water treatment to protect boilers is degasification and deaeration.

Renewable Energy for Water Treatment

Posted by Anthony DeLoach, President on Jul 10, 2018 8:50:00 AM

One of the largest consumers of energy in the US are the water and wastewater treatment plants.

Because of the need for large horsepower pumps and blowers a municipal water and wastewater treatment plant consumes a tremendous amount of kilowatt hours of electricity. The cost of the energy is factored into the “cost of production” of the treatment of water or wastewater and the “rate base” charge is increase accordingly to the consumer.

Does Renewable Power Work in a Water Treatment Plant?

Because solar energy is “space intensive” you do not see a lot of solar power being deployed across the USA at water treatment plants. This is in our opinion a mistake and most likely the decision was made back when solar power output was much lower. Now with increased efficiency of the solar panels and a decrease in production cost it makes tremendous sense to revisit the use of Solar energy for offsetting the operational cost of a water treatment plant or wastewater treatment plant operation.

Providing solar energy for specific pieces of process equipment is also a viable option when you consider deploying solar energy. As an example, to operate a Degasification tower or Decarbonator utilizing 10 350 watt solar panels will generate 3500 watts during peak day light hours and enough to offset the cost of smaller horsepower blower motors. If the solar panels are configured as a canopy they can also provide a nice shade or protection barrier above the piece of equipment if installed outdoors as most packed column towers are located outside.

What about other forms of renewable energy do they work?

At water treatment or wastewater treatment facilities? The use of Co-generation has been around for many years at Wastewater plant facilities waste water treatment plant. A cogeneration unit is a combination “Generator” to produce power and a “Thermal” energy source to produce heated water. The water can be used domestically or can be used to produce chilled water with the help of a Chiller system. The waste water treatment plant  provides a critical component by producing gases such as “Methane” which can be utilized as a fuel source for the cogeneration unit. Water treatment plants do not produce methane gases or other combustible forms of gases so you normally do not see Co-generation units deployed at a Water treatment facility.

Is pH And Alkalinity The Same?

Posted by Anthony DeLoach, President on Apr 24, 2018 8:13:04 AM

The terms alkalinity and pH are commonly interchanged within the water industry by design professionals and operators. The term “alkalinity” means the ability to neutralize an acid in a water. The waters ability to neutralize the acid and to what extent is based upon what minerals are dissolved within the water to react to an acidic condition. The term pH is a reference expression used to express the levels or intensity of the water to change from “base” to “neutral”, to “acidic”. The ability to change or be a base or an acid is the result of the water’s alkalinity. For more information or to learn more contact the professionals at DeLoach Industries Inc. at (941) 371-4995.

Don't Let Your Water Distribution System Fail You

Posted by Anthony DeLoach, President on Jun 19, 2017 1:25:45 PM

When operating a forced or induced draft water treatment tower system it is important to properly maintain your distribution system. Regardless if the unit is an Aerator, Degasifier, Scrubber, or Air Stripper the distribution system is a critical component that must be designed properly and maintained during the life of the equipment.
