Technology

A continuous, multi-stage biological filtration process.

A continuous circulation system

A stable system is not achieved periodically. It is maintained in motion. Water leaves the pool, passes through three treatment stages and returns balanced, around the clock.

Inspired by natural systems: the filter processes waste biologically and removes the nutrients that feed algae, rather than correcting problems after they appear.

Mechanical filtrationThe brush box captures leaves, hair, and large debris before the water reaches the biological stage.
Biological filtrationBeneficial bacteria in the foam media process organic waste continuously, in the same horizontal-flow filter.
Nutrient polishing (GFO)Dedicated GFO vessels strip residual phosphate for long-term clarity. One vessel for pools up to 30,000L, scaling up to 90,000L with three vessels in the same box.
Clean returnBalanced water re-enters the pool and the loop starts again.

Engineered for efficiency

The pump is submerged within the system, so water dampens the sound. No gravity feed is needed, which allows flexible placement: under a deck, in a pump room or fully out of sight.

No backwashingJust a weekly 20 seconds flush: nutrient rich water can be used for your garden

Zwem works with fresh and salt water. Salt systems need slightly more GFO media to keep nutrient control and clarity at their best.
