Not Every Tank Manufacturer Meets ASTM Standards. Does Yours?

At first glance, most polyethylene storage tanks look pretty similar. It’s hard to tell the difference between a robust, well-designed tank and an inferior one. Over the years, we've found that many customers aren’t aware of the construction standards for polyethylene tanks, or they believe that all tank manufacturers follow the same standards.

Unfortunately, not all polyethylene tanks are designed to meet industry standards, so it is critical to know what to look for and what you’re purchasing. The most important standard for polyethylene tanks is the ASTM D 1998. Here’s what you need to know about the ASTM standard.

Judging the Performance of a Polyethylene Tank

While, at a glance, it’s impossible to gauge the life of your polyethylene chemical storage tank, there are many things to know and consider that will help you extend the life of your tank to its fullest potential. It is important to know that from the production of the tank, through installation, it is expertly manufactured with all of the right gaskets and fittings. After tank installation, it is important to have it inspected regularly to look for problems that could cause tank failure.

Is Your Tank Built For Safe Chemical Storage?

Purchasing the wrong chemical storage tank could be a disastrous decision, so it’s critical to make sure you’re ordering a storage solution that can meet your specific needs.

There are several important factors to consider when you design a polyethylene chemical storage tank for your particular application. Always start the configuration process with the chemical that is being stored, because the chemical’s properties influence the entire tank design, including fittings and accessories, thickness, and materials.

NSF/ANSI 61: The Basics

Most products that come in contact with potable water are tested under NSF 61 with the pH 5, pH 8 and pH 10 exposure waters defined in the standard. These exposure waters were designed to simulate the wide variety of potable water chemistries encountered across North America. However, these exposure waters were not designed to predict leaching of materials caused by aggressive chemicals.

The Latest Advances in Removing PFAS from Water

PFAS continues to make headlines and cause concern because these compounds have been detected in drinking water supplies across the country. The Agency for Toxic Substances and Disease Registry has determined that PFAS accumulation in the human body can have adverse health effects. In response, to provide Americans, including the most sensitive populations, with a margin of protection from a lifetime of exposure to PFOA and PFOS from drinking water, U.S. Environmental Protection Agency (EPA) has established the health advisory levels at 70 parts per trillion. In addition, the EPA has set a drinking water lifetime health advisory limit of 70 parts per trillion (ppt) for PFOA and PFOS. These are some of the lowest limits ever established for a contaminant.
