Using Baffles for Tank Mixing Applications

Mixing chemicals and other substances is a lot like mixing cake batter. A container is involved, as is a stand (or bracket) to support the mixing system. But, if you’ve ever made a cake, you know that you have to move the bowl around to mix all the ingredients. It doesn’t work to stick the beaters down in the bowl and keep them in one place.

Best Practices for Chemical Storage Tank Installation

Poly Processing works diligently to produce each and every chemical storage tank to spec. But if a tank isn’t installed correctly it could lead to damage, leaks, safety issues for personnel, and a shorter tank life. Everyone should take chemical tank installation seriously.

The Hidden Costs of Replacing Your Polyethylene Tank

How do you know when it’s time to replace your polyethylene storage tank, instead of repairing it? No matter what chemical tank manufacturer you use, there are hidden costs to replacing a damaged tank. At some point, it’s less expensive to replace the tank — but that could be years later than you might think. Many companies only calculate the tank purchase cost and shipping costs when deciding whether to repair or replace a chemical storage tank, but there are several additional factors to consider as well. Let’s look at these overlooked factors that contribute to your total cost.

Safe Handling and Storage of Liquid Ammonium Sulfate

Liquid ammonium sulfate (LAS) started as a liquid fertilizer that was applied to hard ground. Today, LAS has become widely accepted as a stable and effective source of ammonia for chlorination in water treatment. Alternatives such as anhydrous or aqueous ammonia are hazardous, sometimes requiring pressurized storage tanks and special handling and safety procedures.

The Two Main Steps of the Wastewater Treatment Process

Wastewater treatment is an extremely important part of making sure that humans treat the earth with respect. The proper treatment of wastewater is essential not only for the environment — due to the use of several chemicals throughout the process, a safe process also keeps employees and your facility safe.

Polyethylene Resin: How Resin Testing Led to Chemical Storage Innovation

Twenty years ago, the availability of commercial grade cross-linked polyethylene (XLPE) for chemical storage tanks was limited to a small number of sources. The limited supply, as well as a wide variation in quality, made it challenging to find quality resin for chemical storage tanks.

A Closer Look At the Toughness of XLPE Through Testing

We get a lot of questions about the standard testing on chemical storage tanks that we do at our facility. Vertical tanks larger than 500 gallons in most cases are extensively tested to ensure that they meet ASTM standards. Depending on customers’ needs, we also offer additional testing on our chemical storage tank systems. Let's take a look at the types of chemical tank testing that Poly Processing performs, how we do it, and why these tests are so important in the chemical storage tank production process.

Are Stainless Steel Tanks the Best Choice to Store Caustic Soda Outdoors?

Sodium hydroxide (NaOH), also known as caustic soda or lye, is a common inorganic compound that is typically used as a strong chemical base. In liquid form, caustic soda becomes “slippery” and tends to find weak points in storage containers, and fittings, and can eventually create drips and leaks.

Will Your Chemical Storage Tank Resist Environmental Stress Cracking?

Environmental stress cracking occurs in plastic tanks over time, under certain conditions. It’s a failure of the polymer material due to surface-initiated micro cracks or fractures. These micro cracks are caused by the combination of stresses and environmental effects.
