Storing 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 chloramination in wastewater treatment. Alternatives such as anhydrous or aqueous ammonia are hazardous, sometimes requiring pressurized storage tanks and special handling and safety procedures.

The Best Tanks For Storing Corrosive Chemicals


Whether you’re an engineer writing a spec for a chemical storage system, or an end-user who is looking for the best way to store corrosive chemicals, there are multiple factors that go into creating a safe storage system. Cost might be your first consideration, but there is more to consider than the initial price of the tank, its fittings and accessories, delivery, installation, and tank longevity.

Proper Storage Protection for Your Diesel Exhaust Fluid

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.

The SCR system sprays diesel exhaust fluid (DEF) into the exhaust gas to help eliminate the NOx emissions in diesel engines. DEF is a combination of urea and deionized water, and the urea from the DEF and the exhaust gas react with a variety of metallic compounds to convert nitrogen dioxide and monoxide into nitrogen and water. 

It is critical that the diesel engine fluid stays pure. Impurities can cause the SCR system to stop, which will shut down the operation of the truck.

Poly Processing works with DEF manufacturers and distributors to provide reliable storage solutions that ensure their DEF stays 100% pure.

Can Your Storage System Meet the Challenges of Polymers?

Polymers are important chemicals used in the headworks of wastewater treatment plants. They facilitate the flocculation or coagulation of solids in the wastewater to produce large curds of solid materials. They also aid in dewatering of digester cake — reducing the water content to make it easier and less expensive to transport waste materials to the landfill.

Polymers are highly viscous environmental stress cracking agents, which means they present unique storage challenges that require the right storage solution for adequate safety and cost effectiveness. Let’s explore these challenges and solutions.

How to Choose the Right Food Grade Storage Tank

Once your food production facility outgrows your 300-gallon totes, it’s time to look into larger storage tanks for food storage and clean-in-place chemicals.

There are several options on the market to choose from, but you’ll need to consider which storage tank can meet your greatest challenges: FDA requirements, full-drain capabilities, and cost-effectiveness.

Design Your Storage Tank to Reduce Sodium Hypochlorite Degradation

Commercial sodium hypochlorite is the product of chlorine and sodium hydroxide. It is typically supplied as a liquid solution with a concentration of about 12%. Although the liquid solution is more expensive than gas, it has a lower health risk, it’s easier and safer to use, and it reduces the risk of releasing chlorine gas — especially in areas that are close to surrounding properties.

Safe Acetic Acid Storage and Use

Acetic acid is a versatile, common chemical that’s used for a variety of purposes. The colorless liquid usually has a sour odor and can cause physical harm if it isn’t handled correctly. It is critical to ensure that you design a proper storage solution because improper acetic acid storage can risk the health of the people who work near it.
