The BROAD solution filter (BHESF) continuously purifies the lithium bromide solution circulating in the absorption chiller.
The circulation pump first sends the solution into the activated carbon pre-filter. Most organic matter and ions such as Cu²⁺ and Fe²⁺ (after a redox reaction) are removed there by physical and chemical adsorption. The solution then passes through the ultrafilter, the second filtration stage, before returning to the chiller.
