RAW- Arsenic Ceramic Balls

Filtration media Adsorbent

Arsenic Ceramic Balls are ceramic adsorbent balls made to capture dissolved arsenic from water as it flows past.

• Made of: Ceramic arsenic adsorbent; exact make-up not yet confirmed

• Form: Balls

• Main job: Made to adsorb arsenic, mainly arsenic(V)

• Used in: Waslix custom layered cartridges; also sold loose by weight

What it does

Arsenic adsorbents hold arsenic on metal-oxide surfaces, most often iron or aluminium oxide, so it stays in the media instead of reaching the tap. Arsenic(V), the form usually found in chlorinated water, is captured more readily than arsenic(III).

• Arsenic(V): adsorbent media are among the arsenic treatments the US EPA recognises for small systems and single taps

• Arsenic(III) is harder: untreated well water can carry arsenic(III), which EPA notes may need oxidising to arsenic(V) first

• Phosphate and silica compete: they take up the same surface sites and shorten media life

Evidence: well established Arsenic adsorption on iron- and aluminium-oxide media is documented by the US EPA and peer-reviewed studies. That evidence covers the medium type: the make-up of these balls is not yet confirmed, and we have not seen independent test results for them.

Where it goes in your filter

Arsenic adsorption needs contact time and is weakened by high pH and phosphate, so this medium belongs early in the cartridge.

• Layer position: Early to middle, before calcite, alkaline or mineral balls and any polyphosphate layer

• Pairs well with: Activated carbon for chlorine and taste; Fluoride Ceramic Balls if fluoride is also a concern

• Keep in mind: Use several layers and a slow flow; it does not reduce nitrate, fluoride or bacteria

Specifications

Handling & care

• Before first use: Rinse until the water runs clear to wash out fine dust

• Storage: Keep sealed and dry, away from chemicals

• Replacement: Replace it when tests show arsenic rising; used media holds the arsenic it removed, so dispose of it by local rules

Common questions

How well any medium works depends on your water, the flow rate, contact time and the other layers in the cartridge. This page describes the loose medium, not a certified filter system.

Ceramic adsorbent balls for arsenic reduction. Adsorbent media capture arsenic(V) more readily than arsenic(III), and work best before any layer that raises the pH or releases phosphate. Arsenic has no taste or smell, so confirm results with a lab test of the filtered water.
