Pellet softening vs. lime softening for water plants
What is pellet softening? Pellet softening is a fluidized bed reactor technology for precipitation-based water softening. It uses caustic soda or lime to raise the pH of the water to create a precipitation reaction to reduce calcium in the water. The chemistry principles behind pellet softening is similar to that of lime softening, which has been traditionally used in drinking …
