What is the purpose of a booster pump in a water treatment system?

The purpose of a booster pump in a water treatment system is primarily to increase the product water flow. In many applications, particularly in reverse osmosis (RO) systems or filtration systems, adequate water flow is essential for achieving optimal performance. A booster pump enhances the pressure applied to the system, which helps to push more water through the membranes or filters. This increased flow not only improves the efficiency of the treatment process but also ensures that the system can meet water demand requirements.

In the context of other options, while managing waste or reducing input pressure may involve different types of system components, they do not directly relate to the principal function of a booster pump. Additionally, energy consumption management is influenced by the entire system design and operation rather than a dedicated function of the booster pump itself. Thus, the choice that precisely defines the role of the booster pump is its capability to increase product water flow.
