Reducing backwash in pools and hot tubs with HydroFLOW®

It really is worth taking a good look at our water treatment solutions for swimming pools and spas.

In this blog I want to focus on how HydroFLOW® saves on heating costs and water use by improving the operation of pool or spa filtration systems.

Filters in swimming pools and spas remove small, suspended particles from the water. The most basic idea is that they act like a sieve, allowing the water to pass through, but picking out theses particles. The smaller the particle, the harder it is for the filter to remove it.

With HydroFLOW®, the filters can perform more effectively because it clumps the particles together and makes them easier to clean. Consequently, we get two additional benefits. It improves the water clarity. It also reduces the need for Backwashing the filter, both in frequency and duration.

Up to 10% of pool water can be used in each backwashing cycle. By using HydroFLOW® you can save your backwashing costs in three ways. The cost of disposing this water. The cost of water to replace it. The cost of heating this replacement water.

Some pool users will add chemical flocculant to help the filter perform better. HydroFLOW® is able to flocculate without the cost of chemicals. And the flock formed is stronger and longer lived than chemically formed flock. That is why we call this a non-chemical flocculation process.
