This is the fourth article in Poly Processing’s Innovation Series, where you’ll discover the many innovations that we have introduced to the chemical storage industry.

One of the biggest challenges in vertical tank design is maintaining the tank’s integrity while still allowing for the tank to be fully discharged, cleaned, and properly maintained.

Traditional tank maintenance can be a challenge with many chemicals — so Poly Processing Company has developed a unique full discharge system that helps minimize the hazards associated with traditional vertical tank maintenance.

Sodium hypochlorite, or bleach, is one of the most commonly used chemicals across all industries. But that doesn’t mean you should use a common chemical storage system to contain this aggressive oxidizer. Whether you’re using a bleach concentration of 0.8%, 6%, or 12.5%, sodium hypochlorite will attack your storage tanks more aggressively than most other solutions. Without the proper storage tank system, you could be looking at a tank failure in less time than you expect.

Bulk stored chemicals can become contaminated from two major sources: debris and moisture. As the product is emptied from the chemical storage tank, dirty air and moisture can be drawn into the tank. Temperature fluctuations can also cause the tank to expand and contract, so that it “breathes” contaminants in and out.

Maintaining chemical purity is essential in many industrial chemical applications, such as computer chip manufacturing, food processing, clean in place, and pharmaceutical manufacturing. Contaminated chemicals can become less effective, and more hazardous to your storage equipment. 

To prevent contamination, Poly Processing often recommends installing special accessories. Tank vent dryers and desiccant filters may be your best choice for keeping moisture out of the chemical storage tank.

In the United States, hazardous materials are regulated by the EPA, Occupational Safety and Health Administration (OSHA), Department of Transportation (DOT), and possibly local agencies as well. Each organization has its own definition of hazardous materials.

You’ve heard the adage, “if a job is worth doing, it’s worth doing right.” Poly Processing believes this to be true 110% of the time when it comes to containment. Every single piece of a tank system needs to be completely secure to protect your workspace, your employees, the environment, and the chemical being stored. Thus, when you install a tank-within-tank or double wall system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting.

Sulfuric acid is one of the most widely used chemicals in the United States. More sulfuric acid is produced every year than any other chemical. It has a multitude of industry-specific uses, such as the production of other chemicals, dyes and pigments, water treatment and fertilizers.

This heavy, corrosive chemical requires a specifically designed storage system. That’s why Poly Processing follows guidelines that help ensure safety and enhanced useful tank life.

Not all high-density polyethylene tanks are created equal. Although they sound nearly identical, linear polyethylene and cross-linked polyethylene (XLPE) chemical storage tanks have significant differences. Those differences could impact your organization’s bottom line, your people’s safety, and the operations of your facility.

You may spend a little more on a Poly Processing cross-linked polyethylene tank, but it could possibly cost much you more to own other tanks. Here’s why.

Many industrial chemical applications use mixers to create products, keep chemicals in suspension, for wastewater treatment purposes, or to dilute the chemical. Polyethylene tanks are well-equipped to handle that type of process, as most chemicals can be safely combined. In this article, we’ll discuss three basic types of mixing systems that our tanks use.

Anytime a chemical storage tank is located outside, it’s exposed to harmful elements, such as sun, wind, and rain. Poly Processing recommends taking special considerations to protect the life of your storage tank, especially from damaging ultraviolet rays.
