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 roadway surfaces and aircraft. The substance used for de-icing depends on its application, the amount of snowfall, the municipality’s preferences, and winter temperatures. A variety of chemicals are 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.
Anytime a chemical storage tank is located outside, it’s exposed to harmful elements, such as sun, wind, and rain. Poly Processing recommends taking special considerations to protect the life of your storage tank, especially from damaging ultraviolet rays.
As industries develop innovative solutions to problems, many companies need polyethylene products that aren’t currently being produced by manufacturers. These organizations turn to specialists to design custom-built solutions.
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.
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.
It comes as no surprise that a new wastewater treatment plant can cost hundreds of millions of dollars. Upgrading a plant can cost several million dollars as well. Yet, the chemical storage tanks that go into those plants are one of the least expensive items.
Barium is a chemical found at relatively low levels in nature, but if it seeps into the drinking water, it can cause a variety of potential health problems. Due to these significant health risks, the Environmental Protection Agency (EPA) has ordered all water treatment plants in areas with higher levels of barium to remove its contents from the water prior to releasing it to the public for consumption.
The food and beverage industry has a long history of relying on stainless steel storage tanks due to the belief that the resins in a polyethylene storage tank allow leaching and bacterial growth with food dyes and other food products.
Safe water storage is important for both residential and commercial uses. In residential applications, homeowners capture rainwater for watering lawns and gardens. Water storage is necessary in a wide variety of commercial processes, including farming irrigation, livestock care, and cleaning.
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?
