In an effort to reduce nitrogen oxide emissions from diesel engines, the EPA issued emission regulation standards in 2010. Selective Catalytic Reduction (SCR) technology, requiring Diesel Exhaust Fluid (DEF), sprays the DEF solution into the exhaust to eliminate NOx emissions in diesel engines.
Pneumatically filled chemical storage tanks have the potential for becoming over-pressurized. Over-pressurizing a storage tank through repeated fill cycles can damage and weaken the tank sidewalls, resulting in stress cracks and premature tank failure. Proper tank venting is needed to prevent over-pressurization.
High-density cross-linked polyethylene offers superior value for storing a wide range of critical chemicals. Gel level testing is the ASTM D-1998 method used to test the cross-link density of the polyethylene. The ASTM standard establishes a minimum for the percentage of cross-linked or polymer connected chains. This article and the downloadable technical bulletin will help to explain this standard.
Having complete bottom drainage in a storage tank is key for safety and proper tank maintenance. Safely maintaining chemical storage tanks presents numerous challenges. Let’s compare the two bottom drain options: the traditional metallic insert fitting and Poly Processing’s IMFO system, or Integrally Molded Flanged Outlet.
While many of the chemicals stored within polyethylene tanks do not require side manways, they are available and have several benefits. Fiberglass and stainless steel side manways provide the end user with the ability to do cleanout, maintenenance, etc. without entering the tank through the top opening. The connection between the side manway and the storage tank is designed with a radiused mounting saddle and hardware that provide the key to achieving an excellent sealed connection.
Sodium hydroxide, also known as caustic soda or liquid lye, is commonly used to adjust pH levels in water and wastewater treatment. Caustic soda is also used in the manufacturing of chemicals, rayon, cellophane, paper, detergents, soaps, and a variety of other products.

A PTFE expansion joint is incorporated to allow the tank to expand and contract freely during loading and unloading. This fitting virtually eliminates damage from piping vibrations caused by pumps.
In most cases, chemicals stored in polyethylene tanks require venting. In some instances, the harmful fumes emitted from the chemicals can not be directly released to the atmosphere. In order to reduce the harmful fumes before they evacuate the system and to control air pollution, fume scrubbers are installed.
Let's take a look at how fume scrubbers work and the scrubber solutions for polyethylene tanks offered by Poly Processing Company.
Safe chemical storage is our number one priority. A safe storage solution is able to stand up to impact, UV attack, chemical attack and should be able to withstand catastrophic failure. Poly Processing Company in conjunction with the University of the Pacific in Stockton, CA conducted a pressure test to compare the strength of our cross-linked polyethylene tanks to an ordinary linear polyethylene tank.
We're always working to improve the strength and longevity of our polyethylene tank solutions. In a measure to see just how much force a storage tank could stand up to, we performed a series of tests.
Stainless steel has long been the tank material of choice for storage in the food and beverage industry. Historically, businesses have been hesitant to choose polyethylene storage solutions, believing the porous resins would allow leaching and bacterial growth.
Now, with advanced resin technology, polyethylene offers FDA/CFR compliant storage with cost savings advantages for food and beverage operations.
At Poly Processing, our goal is to build innovative solutions to complex chemical storage challenges. Far beyond simple plastic tanks, we have developed a variety of products to address specific needs of chemical storage in order to ensure safety, ease of maintenance, and tank longevity.

It’s simple common sense. A longer-lasting storage tank is a less expensive storage tank. One question we hear frequently is: “How long should a high-density crosslinked polyethylene tank last?”
A wide variety of colors are available for polyethylene storage tanks. Cosmetics to match the surrounding buildings and landscape, customer preferences, and the application or the chemicals being stored are factors determining tank color selection. However, one color almost always selected for higher end storage solutions, such as storing harsh, aggressive chemicals such as sodium hypochlorite, is black.
Sodium hydroxide is commonly used in wastewater treatment to adjust the base pH levels. This chemical is also widely used in manufacturing a variety of products such as chemicals, rayon, cellophane, pulp and paper products, aluminum, detergents, and soaps. The properties of sodium hydroxide present special storage and handling challenges. This article will examine the properties of sodium hydroxide and appropriate storage solutions.
Fats, oils, and greases present a significant challenge to municipal solid waste and waste water treatment operations. Most waste water blockages can be traced to an accumulation of fats, oils, and greases, resulting in sewage spills, manhole overflows, and sewage backups in homes and businesses. As a result, many municipalities already confronted with tight operating budgets, are passing the cost and responsibility of storing and disposing of fats, oils, and greases along to businesses.
Leachates are liquids that migrate from the waste from landfills. Rainwater and moisture existing in landfill waste produces the leachates which carry dissolved or suspended contaminants. It’s essentially the waste from the landfill that can potentially seep into the surrounding ground and surface water. The landfill is responsible to control of this potential contamination.
The ability to mix chemicals is crucial in certain industrial processes and wastewater treatment applications. The primary goal for a polyethylene chemical storage mixing system is that it is properly designed to mix chemicals safely and cost effectively.
Polyethylene tanks are able to accommodate a wide variety of fittings and locations of fittings. A common point of confusion that we hear from customers is: Which fittings can I use on my tank, and where can they be installed?
Polymers are used in the headworks of wastewater treatment to facilitate flocculation. Polymers also aid in de-watering of digester cake, reducing the water content and permitting easier, less expensive transport of waste materials to the landfill. Polymers present unique storage challenges and require the right storage solution for safety and cost effectiveness. Let’s explore these challenges and solutions.

On the surface, polyethylene storage takes can look pretty similar. It’s tough to tell a more expensive, well-designed and constructed tank from a cheap, inferior tank. Many customers are unaware that there is a standard for tank construction based upon resin properties and testing, or they simply assume all tank manufactures follow the ASTM D 1998 standards.
Poly Processing stands alone in the chemical storage tank industry as the only manufacturer to NSF/ANSI 61 certify not only the polyethylene tank itself, but all fittings and parts within the chemical storage tank system. This delivers peace of mind to waste water treatment facilities, knowing the entire system meets the highest standards for public safety.
