a) Direct interception or sieving: Particle of 0.5 μm and larger "runs into" a pore that is smaller than the particle of topmost layer of the ceramic and are captured as with absolute pore rated synthetic dead-end membranes.

b) Bridging: Smaller than 0.5 μm particles may be too small to be intercepted however two particles hitting the obstruction at the same time will form a bridge across the pore adhering to each other. Bridged particles may not plug the pore creating even smaller pore gradually forming a "filter cake". This "cake" creates a finer filtration for subsequent interception at the cost of decreased flow rate and eventually no flow rate.

c) Inertial impaction: Particles flowing through the filter hits none porous surface barrier it become captured while the water flows around the barrier. Inertial impaction is more prevalent with smaller particles in range of 0.1 to 0.4 μm size as these particles are easily affected by molecular bombardment.

3 Applications of BONA healthy ceramic material

3.1Solution of healthy ceramic materials in water clarifier, barreled water, and dual water supply:

There are several types of water clarifier, including two-step filtrations, three-step filtrations, UF filtration, Nano filtration, RO (Reverse Osmosis) water purifier, etc, containing three-step prepositive filtration, one-step Reverse Osmosis precise filtration, and one-step postpositive filtration. They can partly eliminate bacteria, virus, heavy metal, pesticide, organic substance, as well as special colors and tastes etc. So they can purify water quality. However, most water from purifier is only pure, but without activation and mineral substance. It can affect our health after long-time drinking.
The dual water supply system means that tap water is re-purified process basing on drinking in a building, a community or a city. and it is distributed to users by special pipeline. Although comparing with tap water, this kind of water has high degree of sterilization and purity. But it does not have functions of water mineralization and activation as we hope.
BONA healthy ceramic filter of new generation has functions of highly effective antibacterial, water activation, purification and mineralized. By adding some healthy ceramic materials in the anterior section, middle or the end water clarifier or the dual water supply system, which can healthfully dispose the water and reach the standard of healthy drinking water.

3.2 Solution of healthy ceramic material in water heater
The incrustation and corrosion problem of electric water heater boiler is one of puzzles disturbing this industry. We can find out that, from the design goal and characteristic of the multifunction ceramic ball, also from its effectivity of preventing the accumulated dirt of water tank and pipeline in inhabitant districts and office buildings, this product can not only anti-bigriming but also activating water.
We infer its action mechanism as follows:

1) Massive strong oxidants in water can attack bacterium's cell membrane, damage their protein even DNA, make bacteria deactivated, and then decomposing bacteria's corpse and form a condition without second pollution. When bacteria, the microorganism and the colloid it produced in water are largely reduced, various inorganic impurities will be not easy to deposit and form dirt and hard dirt on pipeline surface. and even if there is accumulation of soft dirt, it can float in water or slightly stick to metal surface, which can be washed with water.          Page <  1 | 2  |  3  |  4  |  5  |  6  |  7  |  8 >
