The efficient use of Pumice for Water Filtration

The efficient use of Pumice for Water Filtration

Pumice for water treatment involves using natural volcanic glass ground into granules. These granules have a highly porous structure that makes them excellent for trapping contaminants and sediment in water filtration processes. Pumice stone for water filtration is characterized by a high surface area and abrasive properties that enhance its effectiveness as a filtration medium.

Read on to learn about the various applications of Pumice in water treatment. 

What is Pumice for Filtration?

Pumice is an aggressive filtration media, particularly compared to sand. That's because pumice media efficiently traps impurities on two levels: between particles and on the particle surface—those abundant, sharp-edged nooks and crannies effectively grab and hold the gunk. 

Pumice media is deployed to treat municipal and industrial effluents and sand-filter-type tank systems, such as drip irrigation systems, which filter emitter-clogging turbidity out of the water. Pumice's low specific gravity and high Pumice make it ideal for Pumice applications and treatment processes. 

Pumice media is available in wide grade options, allowing the filtration media to be customized for particular jobs and system types. Its utility in filtration includes filtering soils, odor control, and cleaning out beverages and oils. 

The various uses of Pumice in Water Filtration

  • Pumice is a versatile filtration media and is widely used for the following applications- 
    Municipal Water Treatment: High-quality Pumice filters out impurities, pathogens, and particulate matter from municipal water supplies to ensure safe and clean drinking water.
  • Industrial Water Treatment: In industries, Pumice purifies waste before it is released into the environment. It helps remove heavy metals, oils, and other harmful contaminants.
  • Aquaculture: In aquaculture systems, Pumice purifies water, maintaining the health of aquatic life. It effectively filters biological waste and feed residue.
  • Swimming Pools: Pumice stone filters are used in swimming pools to achieve crystal-clear water and reduce the use of chemicals.

Top 7 advantages of pumice filter media 

Here are the advantages of using pumice filtration media over conventional granular filter media. 

  • Less pressure loss through the filter as the unique nature of Pumice allows increased solids retention capacity and higher particulate loadings. Therefore, filter run times are increased without deteriorating filtrate quality.
  • This deep filtration avoids particle build-up within the top of the filter bed, reducing head loss across the filter.
  • Pumice's lightweight nature means lower backwash rates are needed to fully expand the filter bed. As a result, the filtration plant's operating costs can be substantially reduced, as backwash consumption is 30% less than that of traditional average.
  • Pumice's lightweight nature allows for expansion over traditional media using the same backwash rate. Again, this offer offers substantial savings in energy and water usage that equal a reduction in pumping needs and allow for downsizing the filtration plant.
  • Pumice stone for water filtration can be used even at temperatures ranging from 0-40 degrees Celsius.
    The filter media has been proven to work successfully in saline or freshwater conditions.
  • Pumice filtration media is also used when an extremely high-quality filtrate is needed. It even removes suspended solids down to 10 microns.
