Fresh And Alive's Biontech BTM-3000 creates medical grade super alkaline and acid waters tens to hundreds of times stronger than popular flow-through models, while remaining competitively priced. Unlike flow-through ionizers, which connect to your faucet or plumbing line and electrify the water as it flows through, the Biontech batch model holds water in two tanks, one acid, and one alkaline, separated by a porous membrane. Using medical-grade platinum coated titanium electrodes, the Biontech electrifies the water with direct current electricity. When used as directed, the Biontech Ionizer makes a half-gallon each of pH 10 to 11 alkaline water with ORP of -800 to -1,000 millivolts, and pH 4 to 5 acid waters with ORP of 800 to 1,000 millivolts every hour. These values are tens to hundreds of times stronger than found in flow-through models. The primary weakness of Flow-through ionizers is their dependent on the quality of water coming from your tap. All ionizers must have minerals in the water to make ions that give the water a strong pH and electrical charge, the fewer minerals you have in your water, the weaker your ionized water will be. If you have limited minerals in your water, you will have weak ionized water, and many municipal supplies and wells have poorly mineralized (and frequently toxic) water. With the Biontech you can buy good bottled water or add your own trace minerals in order to make strong ionized water. You can use any of the expensive flow-through ionizers that connect to your faucet such as Jupiter, Kangen, Enagic, Tyent, Microwater, and Delphi, but if your water is poor quality, you'll wind up with low pH values and ORP values. With the Biontech BTM-3000 you have control over both the quality of water used and the strength of ionization, features not found in any flow-through model on the market. Among the Biontechs features are a timer that will automatically chime and shut off when done, and decanting at the touch of a button.
