BILL-DEL

DeLoach Industries, Inc. is one of the oldest and most trusted O.E.M. that manufactures Water, Wastewater, and Odor Control/Air emission  equipment in the United States.  DeLoach Industries and its founder Walter W. DeLoach (Bill) was a pioneer in the early development first of fiberglass manufacturing which was a relatively new and an unheard of technique.  Bill invented what became one of the first “chop” glass systems for FRP applications in the industry to allow FRP to be utilized for shapes and bends as needed in tanks and towers.  As DeLoach Industries developed the processes, Bill set his focus on the treatment and purification of “Water” and “Wastewater” and “Odor Control” or “Hydrogen Sulfide” treatment.  His interests helped developed the means and methods that are commercially used today in all water treatment facilities

For many of us who grew up in the industry may recall the old slogan “Hey Culligan Man” but may not know that the home aerator commonly sold with the local Culligan dealer and that is still in production today by a wide variety of companies was originally designed and developed and manufactured by DeLoach Industries Inc., or as the Company's name was years ago before Bill changed it to better describe the variety of markets he was serving, was called “DeLoach Plastics”.  Bill DeLoach pioneered and commercialized the home aerator in the early 60’s which catapulted the company into the water and wastewater purification business.

Industrial Boiler Feed Water For Steam

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

Industrial Boiler feed water in water treatment.

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.

Degasification towers remove

hydrogen sulfide (H2S) and carbon dioxide (CO2), and quite often dissolved oxygen (DO). Removing dissolved corrosive gases is critical to the life and efficiency of the boiler and if the gases remain in the boiler feed water such as carbon dioxide (CO2) it will create a recipe for disaster, higher operating cost, and a reduced life for the boiler system. The carbon dioxide (CO2) will convert into carbonic acid and form a corrosive condition for the boiler and other critical components. If a boiler system is operating an ion exchange process prior to the boiler the regeneration cost will increase dramatically because the resins will be consumed by the carbon dioxide (CO2). In addition to preserving and increasing the life of the resin the removal of the carbon dioxide (CO2) will elevate the pH of the water without the addition of other chemicals again lowering the operating cost of the system.

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.

Steam Process Water Systems

Posted by Anthony DeLoach, President on Jun 26, 2018 8:06:00 AM

Degasification towers remove hydrogen sulfide (H2S), carbon dioxide (CO2), and quite often dissolved oxygen (O2).  In process water systems where the water will be used to heat and turn into steam it is critical that the water chemistry be fully understood and a properly designed treatment system utilizing degasification, decarbonation, or deaeration to be applied. Removing dissolved gases is critical to the life and efficiency of the boiler and allowing dissolved gases such as carbon dioxide to remain in the water is a recipe for disaster and reduced life. The (CO2) will convert into carbonic acid and form a corrosive condition for the boiler and other critical components. In addition, the removal of the (CO2) will elevate the pH of the water without the addition of caustics. The selection of what type of degasification tower system should be based on the specific applications, site conditions, and water chemistry. DeLoach Industries understands the many different requirements needed for each individual Industrial Water Treatment system. For more information or to learn more contact the professionals at DeLoach Industries Inc. at (941) 371-4995.

Deaeration Vs. Decarbonation

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

The term De-Aeration refers to a specific process utilized to remove carbon dioxide as well as dissolved oxygen from a water stream. Typically associated with boiler feed water systems and utilized as a method to remove Carbon Dioxide (CO2) and Oxygen (O2) from the water prior to entering the boiler. The Decarbonation system also removes Carbon Dioxide (CO2) from the water and typically does not target the removal of Oxygen (O2). A De-Aeration system utilizes steam which enters at the bottom of the tower. The inlet feed water is heated, as close to saturation temperature as possible utilizing a minimum pressure drop and a limit on the vent. This ensures the best thermal operating efficiency of the tower.

Saving Steam With Degasification

Posted by Anthony DeLoach, President on Jun 5, 2018 12:00:00 AM

At most, business operations that utilize steam there is an awareness of both the potential short supply as well as the ongoing operating cost to produce the steam. Steam is utilized from simple task of heating buildings and pipes to more complex operations like distillation for use with the food and beverage markets or pharmaceutical industry. Oil refineries desperately depend on steam and is part of their key foundation of their operation.

When designing a system it helps to reduce the need for steam whenever possible, by selecting water treatment processes that are not dependent on steam such as a “Decarbonator”.

Dearation in Water

Posted by Anthony DeLoach, President on May 31, 2018 12:00:00 AM

Removing gases to protect your boiler

The process of removing dissolved gases from feed water to steam-generating boilers is often referred to as “Deaeration”. During the deaeration process dissolved oxygen (02) and carbon dioxide (CO2) are removed prior to entering the boiler. If the gases are not removed prior to reaching the boiler system, the boiler will experience serious corrosion damage. The gases, when in contact with the metallic equipment will form oxides (rust) and it will attach to the walls of the piping and tubes and over time completely shut down the boiler. The dissolved carbon dioxide combines with the water and forms carbonic acid that also further enhances the corrosion process.

Most deaerators utilize steam to enhance the removal of the dissolved gases and levels are typically reduced to 7 ppb by weight or less for the oxygen (02) and the removal of carbon dioxide (CO2). For a system only needing CO2 removal then a decarbonator is typically used as it operates without the need for steam and for much less operating cost. For more information or to learn more contact the professionals at DeLoach Industries Inc. at (941) 371-4995.
