Abstract: The present invention describes the design of low-cost ionizers operated in batch and continuous modes for the production of alkaline water for drinking and medical  purposes. The device consists of a titanium-based cathode electrode and mixed metal oxide-coated titanium electrodes as an anode. The feed water of TDS ranging from  250-350 ppm is pre-filtered for removal of turbidity, color, and odor. The clarified water is passed through the anode and cathode chambers separated by high flux  nanofiltration (NF) membrane/ microporous polyethylene terephthalate for ion transfer. The supply of voltage of 9-36 V facilitates the splitting of the water molecule  and the movement of cations across the barrier from anode to cathode. Hydrogen gas gets eluted out at the cathode side that is thereby enriched in OH- ions and the  essential minerals. A negative oxidative reduction potential (ORP) of -100 mV to -600 mV is achieved which neutralizes reactive oxygen. The alkaline ionized water of  pH 8-10 produced from the cathode side of the ionizer has been tested for toxic metals and pathogens, whereas the acidic water of pH less than 7 generated at the anode  side can be utilized for cleaning and washing purpose. The alkaline ionizer costs just $ 100-150 as compared to the highly expensive alkaline water generators supplied  by multinational companies. The operating cost is found to be only Rs 1.0 per L of alkaline ionized water produced.
Startup Options: The alkaline ionizer costs just $ 100-150 as compared to the highly expensive alkaline water generators supplied by multinational companies. The operating cost is only Rs 1.0 per L of alkaline ionized water produced.
