Ferrics, alums and polymers are commonly used to treat water and wastewater. There are several reasons why these substances require specialized storage: Separation, settling and coagulation are major issues with these chemicals – and those conditions can be compounded by temperature variations. Settling and separation issues can lead to difficulty in pumping the chemicals.

Sulfuric acid can be a tricky chemical to store. Used in a wide variety of industrial applications, sulfuric acid is heavy, can create toxic or flammable gas, and can burn the skin. A smart storage solution for sulfuric acid should start with a well-thought-out tank design — not just the tank material but the entire storage system and all its components. Thinking through the entire sulfuric acid tank system design up front will help you protect your employees, the environment, and your investment. Read on for our recommendations on the right material, configuration, and standards for safe sulfuric acid storage.

Sodium hypochlorite is a well-known and aggressive oxidizer that is used in many applications. Our end-use customers often use “hypo” in the water treatment business to eliminate bacteria and viruses from water supplies. Anyone looking to maintain a safe and secure storage tank system has three challenges to overcome: UV rays, off-gassing, and oxidation. Over the years, Poly Processing has established a set of industry leading best practices that represent an ideal sodium hypochlorite storage system for overcoming these challenges.

Sodium hydroxide, also known as caustic soda or liquid lye, is commonly used to adjust pH levels in water and wastewater and can easily change hard water to a much closer approximation to neutral when injected into the water treatment system. Caustic soda can act as a corrosion inhibitor without the uneven distribution of calcium carbonate. Caustic soda is also used in the manufacturing of chemicals, rayon, cellophane, paper, detergents, soaps, and a variety of other products.

Hydrofluorosilicic acid, or H2SiF6, is a challenging chemical because it has properties that pose a danger and specific storage concerns. With its common use in water treatment, it’s important that you’re aware of the risks of improperly storing this chemical. Let’s take a closer look at the nature of hydrofluorosilicic acid, its applications, the specific storage concerns and solutions, and safety considerations when working with this complicated chemical.

In 2010, the Environmental Protection Agency mandated the use of selective catalytic reduction (SCR) in diesel engines. In an SCR-equipped vehicle, the exhaust gas from the engine goes through a particulate filter to eliminate the soot and ash generated from burning diesel fuel.

One of the most popular chemicals that Poly Processing polyethylene tanks store in the market is Hydrofluoric Acid. It's not only a commonly used chemical, it's also one of the more dangerous chemicals. That's why safe and proper storage is so important.
Firefighting foam is commonly used at airports, hangars and other locations where hazardous fires can occur. The foaming agent used in the foam in most cases is a surfactant based chemical. Surfactants are compounds that lower the surface tension between two liquids, or a liquid and a solid. Dishwashing liquid contains surfactants—and like firefighting foam, it foams up when it mixes with water.

Sodium hydroxide, also known as lye or caustic soda, is used to neutralize the pH of water in a variety of applications. The chemical leaves no residual color, is a high-strength product, and is available at concentrations of two to 50 percent. Most of our customers use it in 25 to 50 percent concentrations.
