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 that are defined in the standard. These exposure waters were designed to simulate the wide variety of potable water chemistries encountered across North America. However, the exposure waters were not designed to predict leaching of materials caused by aggressive chemicals.

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.

A wide variety of colors are available for polyethylene storage tanks. Cosmetics to match the surrounding buildings and landscape, customer preferences, and the application or the chemicals being stored are factors determining tank color selection. However, one color which is almost always selected for higher end storage solutions, such as storing harsh, aggressive chemicals such as sodium hypochlorite, is black.

Poly Processing's tanks are manufactured in the United States and are able to accommodate a wide variety of fittings and locations of fittings. This flexibility allows for proper inputs and venting, ensuring a safe and effective solution for a given chemical and longer tank life as well. A common point of confusion that we hear from customers is: Which fittings can I use on my tank, and where can they be installed? We've tried to simplify the answer to that question by considering each area of the tank and the corresponding compatible fittings.

Seismic codes govern structural design to prevent damage to buildings and structures during an earthquake. It’s common knowledge that buildings must conform to specific seismic codes, but your chemical storage tanks also have seismic regulations. Any facility in a seismically active region, including everywhere along the Pacific Rim, must pay careful attention to the safety measures established in the International Building Code.
Chemical leaks present several major challenges for your facility. They can cause damage to storage systems, employees, and the environment. Repair and cleanup costs can be expensive, and the leaked chemical is wasted.
Maintaining the proper temperature of a chemical inside a high density crosslinked polyethylene tank can be critical for safe and effective storage. For example, sodium hydroxide and caustic soda need to maintain temperature to prevent crystallization at lower temperatures.

You’ve heard the adage, “if a job is worth doing, it’s worth doing right.” Poly Processing believes this to be true 110% of the time when it comes to containment. Every single piece of a tank system needs to be completely secure to protect your workspace, your employees, the environment, and the chemical being stored. When you install a tank-within-tank or double wall storage tank system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting. The bellows fitting lets you safely connect the primary tank with the secondary containment tank.
