ZONE SELENIUM Mineral Ball

Home water purification has entered the 4.0 era: consumers no longer ask only “how clean?”, but also “how healthy?”. ZONE Labs offers hard numbers: when ordinary RO permeate is re-mineralised with our Selenium Ion Balls, 3 m³ of water can be passed while keeping Se at 8-12 µg/L and Sr ≥ 0.2 mg/L—fully meeting the Chinese Natural Mineral-Water Standard GB 8537-2018. Today we zoom in on “filter media” to explain why remineralisation after RO is indispensable, and how ZONE Selenium Balls upgrade “pure” water into “good” water.

 

1. RO Reverse osmosis: a double-edged sword  

- 0.0001 µm pore size blocks viruses, heavy metals, antibiotics (≥ 99 % rejection).  

- Draw-back: Ca, Mg, Sr, Se and other beneficial ions are also swept away, producing “academic-grade” pure water.  

- Long-term consumption of low-mineral water is linked to:  

  – Negative mineral balance (WHO Guidelines 2017: 10-20 % of daily mineral uptake comes from water).  

  – Flat taste, poor coffee/tea extraction and consumer dissatisfaction.

 

Take-away: RO is not the finish line; it is the starting point of “second conditioning”.

 

 

2. A quick family tree of post-RO filter media  

Media type	Job	Limits
Dolomite/Calcite	Add Ca/Mg, raise pH	Dissolves too fast, short life, scaling risk
Maifan stone	Release traces	Uncontrolled composition, high heavy-metal background
Ion-exchange resin	Selective Sr/Li	Expensive, needs regeneration
Functional mineral ball (ZONE Se ball)	Controlled Se & Sr release, life ≥ 1000 L	High tech, needs sintering + slow-release coating

 

3. Three trump cards of ZONE Selenium Ion Balls  

 

Card 1 – Metered slow release  

Micro-crystalline selenium-apatite + porous ceramic skeleton, sintered at 1 080 °C, forms nano-scale release channels.  

Dynamic column test: 2 L/min, 120 h continuous, Se curve RSD < 5 %—true zero-order kinetics.

   

Card 2 – Marathon service life  

A 0.5 L post-filter treats 3 000 L. For a family drinking 1.5 L day⁻¹ that equals 5.5 years.  

TDS rise only 8-12 ppm—no scaling, compatible with instant-heat dispensers.

 

Card 3 – Double safety net  

Raw material acid-washed & back-washed with RO water; heavy-metal leaching far below NSF/ANSI 42 limits.  

SGS report: Pb < 0.5 µg/L, Cd < 0.1 µg/L, As not detected.

 

 

4. Real-home validation: from lab to kitchen  

Site: Suzhou, 50 G RO unit, 300 g ZONE Se cartridge  

Period: 90 days continuous draw  

Results  

- Se: Day-1 10.3 µg/L → Day-90 9.1 µg/L (11.6 % decay)  

- Sr: steady 0.22-0.25 mg/L, meets GB 8537 threshold  

- Blind taste: 9/10 panelists rated “sweet”, “no plastic note”; tea aroma persistence +20 %

 

 

5. How to choose & use a Se remineralisation cartridge  

1. Ask for dual Se & Sr reports—missing one = marketing.  

2. Demand decay curve—serious suppliers provide ≥ 1 000 L dynamic data.  

3. Replacement cue  

   – Small dispensers: 12 months or 3 000 L, whichever first  

   – High-flow under-sink: 24 months or 6 000 L (parallel two sticks to extend)  

4. First use: flush 5 min to rinse fines.

 

 

6. Who is ZONE? – 15 years obsessed with “trace elements in water”  

- Plant in Zibo, Shandong, 30 000 m², two 72 m ceramic tunnel kilns, 3 000 t yr⁻¹ capacity  

- Portfolio: defluoride balls, Sr-balls, Se-balls, weak-alkaline balls, exported to 46 countries, ODM partner of several Fortune-500 water brands  

- Website: www.onlyzonewater.com (reports & down-loadable curves)

 

Keep heavy metals out, invite essential Se & Sr back—that is the “last-mile” mission of ZONE Selenium Ion Balls. Next time you open your tap and see crystal-clear water, remember: truly good water is not “nothing inside”, but “nothing harmful and everything beneficial”.
