If you’re storing hazardous fluids such as corrosive acids, bases or aggressively oxidizing chemicals, you need to be confident that your chemical storage tank can meet your expectations for years. You can’t afford to invest in a system, only to discover a year later that your tank isn’t compatible with the chemicals you’re using. That’s a loss of product, time, and money—and it could put your people, equipment and environment at risk, as well.

If you want your polyethylene chemical storage tank to last for its full lifetime, you’ll need to make sure your tank has the right specific gravity rating. Every chemical has its own specific gravity, and it’s critically important that your tank is designed to meet the demands of the particular chemical you’re storing. Tanks that are rated too low can suffer from mechanical stress and early failure.

Purchasing a high-quality chemical storage tank is a significant investment for your company, and choosing the right tank for your needs isn’t always an easy decision. If you’re deciding between a fiberglass reinforced plastic (FRP) tank and polyethylene tank, be sure you understand the differences between them and know what to expect in terms of cost, maintenance, service, and protection.

Cross-linked polyethylene tanks withstand greater pressure, in part because of the rotational molding manufacturing process. Rotational molding is by far the best process to create a cross-linked polyethylene chemical storage tank.

Maintaining the proper temperature of a chemical is often critical to safe storage. For example, sodium hydroxide at a 50% concentration will start to crystallize at or below temperatures of 60 degrees F. With polyethylene tanks, heating pads and insulation can maintain the specific temperature of the chemical you’re storing—even when your chemical tank is exposed to low air temperatures.

Purchasing a chemical storage tank is a significant investment. You want confidence and reassurance that the tank will give you the dependability and longevity that was advertised. A strong and transparent warranty shows that the manufacturer believes in and stands behind their product.

Wastewater treatment requires more aggressive chemicals—and in larger amounts—than municipal drinking water treatment. As a result, it is vital to properly store the chemicals used in the wastewater treatment process.

Poly Processing Company invites you to visit us at booth #1403 at AWWA ACE 2019, June 10-12 in Denver, Colorado.

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 engineered guidelines that ensure safety and enhanced tank life.

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV.

So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
