Available. But pH of the electrolysis acid water (hypochlorous acid water) falls to around 2 to 3.

It is based on just using hypochlorous acid water produced by the device as it is.

Please install it in the well ventilated indoor place basically, (Because a very small amount of hydrogen gas, and chlorine gas are generated from the electrodes.) In addition, please do it under the environment without the fire nearby, with room temperature in 40 degrees Celsius or less and that does not freeze. When you use water cistern, please install it at the lower place than the main device in height.

With the raw materials of water and salt (sodium chloride [NACL]) and electricity only and needless to purchase and store chemicals, the running cost is comparatively economical. In case of KEW-A090-1A, the cost of producing 1 ton of water is about 150 yen. But the water rate is not included because it varies according to the local governments. It does not include the periodical maintenance cost every 2000 hours either.

Please use as raw water the tap water that cleared a drinking water standard or the industrial water or pure water that cleared the items stipulated by water laws through after cleaning water. When it is more than 1mg/L of total hardness (hardness), soft water processing is necessary and the setting of the water softener is necessary. If the customer uses water of industrial use (groundwater, underflow water, river water, etc.) as raw water, water quality measurement becomes necessary in accordance with the required usablility as raw water. The recommended water supply pressure of raw water is 0.15 to 0.35MPa. Even when there is less water supply pressure than this, you may use it, but electrolysis water production decreases, and an available chlorine concentration may change.

There is not any problem even if you just drain it in the case of a small quantity. However, considering the effluent standard of the customer, the customer is expected to neutralize it. In addition, please do not drain it directly to the organic substance processing tank processed by the microbe.

Please use the refined salt with 99.5% or more of sodium chloride (Salt Industry Center of Japan make is recommended). Please use the 25 kgs of refined salt by all means. Please do not use the 1kg of refined salt because it is added with magnesium carbonate. If you use table salt and mineral-rich salt/halite, as it is rich in impurities and low purity, the electrolysis cell life is influenced. Do not use it.

By residual chlorine and iron content included in raw water, the driving situation and setting environment ( temperature, vibration) including reproduction number of times, life of the ion-exchange resin fluctuates, but the ion-exchange resin once in three years and filter exchange are necessary. Please read instruction manuals of the water softener before use carefully.

As for the hypochlorous acid water produced by our electrolysis water generator, it is confirmed that there is an effect to sterilize germs and norovirus (*1) such as staphylococcus aureus, Escherichia coli attaching to foodstuff in a short time. (*2) As the hypochlorous acid water decreases sterilization activity when organic matter exists, the expected sterilization effect will be explicit by processing with hypochlorous acid water with enough cleansing beforehand.
*1 It is confirmed with substitute virus, Calicivirus and mouse norovirus.
*2 State without the organic matter in test tube.

Our electrolysis water generator produces acidulous hypochlorous acid water composed primarily of hypochlorous acid receiving the authorization as food additives (sterilization agent). You can use it for the sterilization of such as vegetables, fruit, raw seafood with a slight chlorine smell emanating. A very small amount of chlorine gas is generated around a device in a generation process. Please do not smell it near a device. As for the hypochlorous acid water, it is confirmed not to remain behind immediately after the washing of foodstuff (including precut salad) in responding to organic matter.

After removing dirt ingredients by washing with detergent or alkaline water and tap water, we recommend a cleansing sterilization method of washing away under running electrolysis acid water ( hypochlorous acid water). In addition, a rinse is possible with tap water after the cleansing sterilization.

You can use the hypochlorous acid water generated with this product as acidulous hypochlorous acid water based on Ministry of Health, and Welfare notification No. 345 (April 26, 2012). You are requested to observe a prescribed ingredient standard stipulated in the standard of food, additive, etc. and the direction for use and please use it appropriately when using.

Sodium hypochlorite is different from hypochlorous acid water (water solution) in that the sterilizing power is weaker than hypochlorous acid water. As a result, a high concentration use is required. There are cases that the safety and smell of chlorine during operations become problematic. The persistency is higher than hypochlorous acid water, thus more elaborate elimination operation becomes necessary. Commercially available sodium hypochlorite (as an aqueous solution) are available in the market with 5 to 12% high concentration stock liquid. There is the case that the chemical burn of the skin occurs by an erroneous dilution method on its use. However, the hypochlorous acid water generated by this device is acidulous and little irritancy to skin. Even by an accidental swallowing by mistake it may hardly cause health hazard to anybody. However, the person of chlorine allergy, please be careful.

There is no problem if they are mixed. You can bring pH close to neutrality by a mixed rate.

If it is in the storage in the sealing state in a normal temperature dark place (or in a shading container) and air tight, it is storable for more than one month. But it is recommended that you use it as soon as possible after electrolyzing it as the effect is the highest immediately after that.

As the hypochlorous acid water deactivates itself as soon as touching the organic matter, it is not available for organic matter disposal such as of feces and vomit and excreta. Please use it for sanitization of the finish after having removed organic matter. About the infectious disease countermeasure such as for norovirus, please refer to guidelines on MHLW HP.
