While liquid chemicals remain the most popular solution, more and more water treatment specialists are turning to solid chemicals to treat the water in their boiler and cooling-tower systems.
Historically speaking, solid chemicals have played a prominent role in water treatment, specifically in the first half of the 20th century when they were used to prevent the corrosion and biological growth that could lead to catastrophic boiler failures.
By mid-century, however, liquid chemicals, buoyed by their ability to be easily blended, had replaced their solid counterparts. While liquid chemicals remain the top choice among specialists, the tide appears to be turning back toward the use of solid chemicals for important reasons including: reduction of water, shipping and disposal costs, inventory space required, etc.
A few of the many advantages of solid dissolver technology:
• Reduces shipping costs
• Reduces inventory space
• Reduces disposal costs
• Eliminates drum-handling and disposal
• Reduces caustic discharge to sewer systems
• Reduces worker exposure to hazards
• Increases energy-efficiency
• Enhances a company’s sustainability profile, better positioning them as “green” suppliers and operators
Solid Dissolver Technology
Solid chemical is diluted by water sprayed up into an inverted bottle of chemical or the bottom of a chemical disc. This ‘make-up‘ process leads to the dissolution of the solid chemical product and the filling of a reservoir with diluted chemical.
This diluted chemical is fed into the system from the reservoir. As the level of the reservoir lowers, an internal primary float drops, triggering a primary solenoid valve which activates the water spray once again. The reservoir will then refill with diluted chemical raising the primary float until it reaches the shut-off point and closes the solenoid, thereby deactivating the spray. This cycle will continue automatically based on demand in the system.
