High flow-through gravity purification system for water

1. A gravity fed purification system comprising:

a purification media comprising a layer, the layer containing 10-20 g of purification material of low ash catalytic carbon comprising an acid-washed carbon that has been heat-treated and washed with a solution containing peroxide, peroxotitanium silicate, and nanozinc or TiO 2 powder, and the low ash catalytic carbon having a nominal particle size range of about 20 mesh to about 50 mesh;

wherein the low ash catalytic carbon has a total pore volume ranging from about 0.80 to about 1.5 cc/g; and

wherein the purification system is able to produce a flow rate of about 1000 to about 1500 cc/min with a volume of about 300 to about 350 cc of water to remove 75% to 98% of Chlorine from the water.

2. The purification system according to claim 1 , wherein the system reduces the level of chlorine in chlorinated tap water with a capacity of 30-100 gallons of water per gram of purification media.

3. The purification system according to claim 1 , wherein the low ash catalytic carbon has a mean particle size ranging from 700 to 900 μm with a standard deviation of 200 to 300 μm.

4. The purification system according to claim 1 , wherein the low ash catalytic carbon has a mean particle size of approximately 730 μm with a standard deviation of approximately 235 μm.

5. The purification system according to claim 2 , wherein the level of chlorine in water passing through the purification system is reduced by 75%.

6. The purification system according to claim 1 , wherein the system reduces the level of benzene in water passing through the purification system to a level that is in accordance with NSF test procedure 53 at a flow rate of 1500 cc/min using 12 g of purification media.
