Can I Use Handrails with a Polyethylene Tank?

Various types of chemical storage systems have handrails along the top of the tank, but Poly Processing tanks don’t. Polyethylene tanks can’t support handrails, and the tanks shouldn’t be walked on. The domed surface can be very slippery, and the plastic can become brittle over time and possibly crack under a person’s weight. So how do you safely inspect manways, check gauges, and service level sensors or mixers?

How To Store De-Icing Fluids Safely

Winter is approaching fast. With below freezing temperatures and snowstorms affecting millions of people each year, municipalities need to be ready to clear roadways and maintain equipment. De-icing fluid is used to break down ice and frost on roadways and aircrafts.

The type of substance used for de-icing depends on its application, the amount of snowfall and winter temperatures. There are several chemicals used in the de-icing process, including brine, magnesium chloride, propylene glycol, and ethylene glycol. Brine is the most popular of these chemicals, but it can damage vehicles or rebar on roadways.

Why Your Chemical Tank Needs Professional Inspection And Testing

When storing any type of chemical, it’s important to conduct routine annual tank inspections to make sure the tanks, fittings, venting, and accessories are in good working condition. You can perform a basic tank inspection on your own by following our installation manual, or the system can be inspected by a Poly Processing field service technician. We recommend having a professional perform an in-depth inspection with testing every 3-5 years.

What’s the difference between an inspection you can do and a professional inspection? Here’s an overview of the inspection and testing our field service technicians perform on your chemical storage tanks.

Why Are Water Treatment Plants Converting from Chlorine Gas to Bleach?

There are several types of chlorine sources that water treatment plants can use: chlorine gas, liquid sodium hypochlorite, or onsite production. Chlorine gas can be more cost effective, but a growing number of states are converting to bulk sodium hypochlorite or bleach. If chlorine gas is more economical, why would water treatment plants convert to sodium hypochlorite?

Confused about NSF/ASNI 61 for Chemical Storage? You're Not Alone

If you manufacture, sell or distribute water treatment or distribution products in North America, your products typically must comply with NSF/ANSI Standard 61. NSF/ANSI 61 sets the criteria for water system components to protect health standards. It’s important that all components in water treatment meet the correct standards to ensure dangerous toxins aren’t leached.

However, there is confusion about NSF-61 certifications, and that confusion could lead to purchasing the wrong product for your application. Let’s explore NSF/ANSI 61 and how to make sure your chemical storage tank system meets the necessary requirements.
