Installation Manual – Hydraloop Cascade and Polisher

Updated on 2024-06-06

INTRODUCTION #

Dear Hydraloop customer,

The Hydraloop Polisher is a water filtration unit for the post-treatment of reusable water coming out of a Hydraloop Cascade set-up. Treated water from the Hydraloop Cascade undergoes additional post-treatment by the Polisher, ensuring even lower turbidity levels and e-coli levels. The Polisher disinfects the reusable water to maintain the water quality from the distribution network to the end user.

The Hydraloop Polisher is directly connected to the Hydraloop Cascade setup, which can consist of up to 10 H600 devices. After post-treatment in the Polisher, the reusable water is stored in a buffer tank. From this buffer tank, the water can be distributed for non-potable usage such as toilet flushing, laundry, and garden irrigation. Depending on the building size, the buffer tank can also supply water to an external booster set-up. Additionally, the buffer tank functions as a contact tank for residual disinfection.
