Our pumice is mined from a land based resource, within 50kms of Lake Taupo in the North Island of New Zealand, and it is characterized by its relative hardness and light weight in comparison to competing aggregates. The washing and screening of our pumice means that no “fine” particles are included.
As a filtration media, pumice is an aggressively-filtering alternative to sand (and other filtration media).
The low specific gravity and high porosity of pumice make it ideal for irrigation filtration systems and other water treatment processes and provides several advantages over other filtration media such as sand, expanded clay, and anthracite.
Benefits of Pumice for Water Treatment Applications include:
- Improved filtration rates
- Better filtration bed expansion
- Less energy consumption
- Larger effective surface area
- Less intensive backwash requirements
- Low-cost filter refurbishment
INPRO pumice has been selected for a number of filtration applications.
