How to build cost-effective storage solutions for wastewater treatment chemicals
Thoroughly understanding the nuances of the chemical’s properties is vital to maximize the operation and performance of the chemical delivery system, as well as the longevity of the chemical storage tank. If you simply design a tank based on generic factors such as size, material and capacity without defining the chemical used, you risk getting a non-optimal tank.

Storing sulfuric acid presents major problems
The highly corrosive nature of sulfuric acid tests the limits of today’s storage systems. Any company that stores sulfuric acid needs to be acutely aware of the dangers that the chemical presents to equipment and personnel. When storing sulfuric acid, it is important to verify the hoop stress rating and understand the specific gravity ratings to make sure the resins used in the storage tank provide a margin of safety. Along with the weight of the chemical, its oxidative properties must also be considered.
Measurement methods for chemical storage tank inventory calculation
The technology used to measure and manage chemical inventories is diverse, with many options to measuring the amount of chemicals inside tanks.
Creating a safe chemical storage system
It is important to consider the durability and longevity of the chemical storage tank system when you’re storing corrosive chemicals.
New water tanks help Saint John deliver abundant and clean water
Residents on the east side of Saint John, New Brunswick, were all too familiar with boil water orders. For decades, the city drew water from Latimer Lake and chlorinated and pumped it directly to the distribution system.
Automation helps maintain water tank levels and prevent freezing in colder climates
The two key factors for water storage are to ensure the tank maintains the correct level and that there is water turnover to protect water quality. In colder climates, low tank turnover can lead to water freezing within it.
