i want to leave this water pure

05/04/2008 11:07 AM

i have a tank of water which i used for manufacturing pasta, this tank is in a hot environment, sometimes the factory didn't work for 2 or 3 days, so the water make a bad smell and some rotens. i want to leave this water for a long time without this bad smell. the tank is a cuboid with 1 m length and 2 m weidth and 1 m heigh. it's a steel tank treated againest rust. i though of put this oxygen motors like those in fish sinks, but it also must be changed, and this water is too expensive to me.

what do you think?

I think I speak for most contributers on CR4 when I ask "what brand name of pasta do you sell"?

I agree with Mike the Boiler Guy, I find the Mikel's request scary. Is his product for sale in shops - what name and which country, does anyone know?

The smell is due to bacteria feeding on the organic matter. What are you planning to do with the water? Cook up more pasta, or reuse it for some other non-potable purpose? If you're planning to use it to cook up more pasta, then sterilize it with ozone or a small amount of bleach to kill the bacteria, then filter the water to remove the organics. If you're planning to use it for non-potable purposes, then install a biological wastewater treatment plant to treat it before reusing it.

Ozone can also be bad for people working near by.

Consider UV purification to kill the organics, then filter. If you control your UV band width with the right emitters, you will not generate ozone.

A very good point, but it should also be noted that UV sterilization is most effective when the water is clear. Water that has been used to boil pasta tends to be very cloudy, and this may affect the effectiveness of the UV system. Using ozone can be made safer by covering up the tank during sterilization.

Evidently the water is not completely pure, otherwise you would not get a smell which is produced by bacteria. Absolutely pure water does not create bad smells. If you must store this water for days in between use, then get absolutely pure water from a water bottling plant that uses Reverse Osmosis process or a distillation process to create he pure bottled water.

Secondly, does this storage tank have an open top? I susprect your baking dough or some food ingredient is the source of the bacteria which subsequently breeds in your water. Adding air might make it worse. Consider ways of preventing the tank and the water from getting contaminating bacteria into it in the first place. Dough and other foods contain bacteria that will breed and grow in a hot moist environment. Where does the water come from in the first place? Can you change your routine somewhat to prevent the water from being contaminated somewhere in between the source and you finally using it to make pasta.

You need a good filtering device on the water installation. It seems a ceramic filter with nanosilver may be good. Nanosilver kills bacteria.

You may consider anodic oxidation which needs some salt in water, but kills bacteria.

We make our own pasta at home and get the best results when the water is very salty. Perhaps enough salt would prevent the bacteria from ever getting started? ...and perhaps improve savoriness?

Good luck

Why is this water so expensive that it has to be reused? We are talking about ~520 gallons. Is it too expensive because of the energy to heat a new batch?

Keep the water near boiling point and filter it before usage.
