What is pcu?

PCU stands for Polyvalent Cation Upflow, which is a type of water treatment system that uses a combination of ion exchange and upflow technologies to remove hardness ions (calcium and magnesium) from water.

PCU systems are commonly used in residential and commercial settings for water softening applications. They work by passing the water through a resin bed that exchanges calcium and magnesium ions for sodium ions, effectively softening the water.

One of the key benefits of PCU systems is that they regenerate using upflow technology, which allows for more efficient use of salt and water during the regeneration cycle. This helps to reduce overall operating costs and improve the system's efficiency.

Overall, PCU systems are a reliable and effective solution for addressing hard water issues in residential and commercial environments. They can help to improve water quality, extend the lifespan of appliances and plumbing fixtures, and provide a more enjoyable overall water experience.
