Ionized water, Ozonated water and Alkaline water

September 29, 2010 Leave a comment

Ionized (higher pH) water is supposed to offer health benefits, but there is little factual evidence to back up this claim. Ozonated water has ozone diffused into it, which acts as a disinfectant, but it is unstable and has a short effective duration.

What Does a Water Ionizer Do?

Passing electrical current through pure water (pH=7), an ionizer generates alkaline (pH above 7) and acidic (pH below 7) water. The alkaline water is dispensed for drinking purposes.

Why Alkaline Water?

Proponents claim alkaline water corrects the body’s pH balance. Since digestion already turns fluids slightly alkaline before they reach the intestines, there is little value to alkaline water.

Instability of Ozonated Water

Since ozone has a half-life of less than 30 minutes, any bottled ozonated water on the shelf will have no ozone left in it. Only an on-site ozone generator will give most people contact with real ozonated water.

Uses of Ozonated Water

Ozone is used for water disinfection in many treatment plants around the world. It oxidizes any organic materials (including disease-carrying organisms) better than oxygen will by itself. So, ozonated water is useful for disinfection (as well as for precipitating many dissolved minerals out of the water) and has a slightly higher level of dissolved oxygen in the water than non-ozonated water does.

Conclusion

Ozonated water offers extra disinfection if your water may be contaminated. For normal water supplies, this precaution is an unnecessary expense, but otherwise it is harmless. Ionized water has a higher pH than pure water. The same effect can be achieved at much less cost with a few gains of baking soda added to your water.

Swimming pool treatment process

Ozonation



Ozonation is written into the German DIN (
German Institute for Standardization)standard specifications for public swimming pools.


However ozone works in a similar manner to UVc in as much that the
process oxidises and chops up organic molecules into smaller components.
However it is also a DIN standard requirement to use activated carbon
after Ozonation which eliminates the THM problem. However the activated
carbon absorbs the free chlorine and will increase the chemical demand
by the pool,typically the chlorine requirement will increase by 500%. In
addition to removing chlorine, activated carbon also absorbs organics,
which makes it a perfect environment for the incubation of bacteria and
the production of trichloramine gas.




In Germany and in any swimming pool system using ozone and activated
carbon there will be a high level of trichloramine in the atmosphere.
This is demonstrated by the excessive corrosion of the ventilation
systems and stainless steel metal work, the structural steel for the
building may also be affected. Every year there are at least one or more
cases of swimming pool roof failure in Europe caused by trichloramines.
At low levels trichloramine will predispose your lungs to infection, or
in the case of children it may sensitise the lung tissue to an allergic
reaction which may in turn lead to asthma when the child becomes a
teenager. It is unlikely that we will ever quantify the damage caused by
trichloramine on public health, in the same manner that it has taken
decades to appreciate the dangers from smoking and


asbestos.

However we should not advocate a technology that actually
promotes the production of a toxic gas. Ozonation systems are being
promoted in many European countries, and they are written into the
German DIN standards, however it is a technology that is actively
causing damage to the lungs of the public visiting swimming pools.

Seawater desalination

Seawater desalination

www.forwardaqua.com
The fresh water supply is becoming an very important problem for many area, someone even forecast that it will be next strategical resource after the oil.

As an additional water supply solution, seawater desalination have been increasing very quickly in last 20 years, and the the desalination cost is low enough for scale use due to technology development.

Reverse Osmosis desalination
Water from a pressurized saline solution
is separated from the dissolved salts by flowing through a
water-permeable membrane. The permeate (the liquid flowing through the
membrane) is encouraged to flow through the membrane by the pressure
differential created between the pressurized feedwater and the product
water, which is at near-atmospheric pressure. The remaining feedwater
continues through the pressurized side of the reactor as brine. No
heating or phase change takes place. The major energy requirement is for
the initial pressurization of the feedwater. For brackish water
desalination the operating pressures range from 250 to 400 psi, and for
seawater desalination from 800 to 1 000 psi.

Advantages

·
The processing system is simple; the only complicating factor is
finding or producing a clean supply of feedwater to minimize the need
for frequent cleaning of the membrane.

·
Systems may be assembled from prepackaged modules to produce a supply of
product water ranging from a few liters per day to 750 000 l/day for
brackish water, and to 400 000 l/day for seawater; the modular system
allows for high mobility, making RO plants ideal for emergency water
supply use.

· Installation costs are low.

· RO plants have a very high space/production capacity ratio, ranging from 25 000 to 60 000 l/day/m2.

· Low maintenance, nonmetallic materials are used in construction.

· Energy use to process brackish water ranges from 1 to 3 kWh per 1 0001 of product water.

· RO technologies can make use of use an almost unlimited and reliable water source, the sea.

· RO technologies can be used to remove organic and inorganic contaminants.

· Aside from the need to dispose of the brine, RO has a negligible environmental impact.

· The technology makes minimal use of chemicals.

What is ozone laundry
system?

Due to the zone
own the features of: strong oxidbillity , dirty removal, bacteria-killing,
stretching fiber, we mix ozone with water at certain content to wash clothes.

Ozone can kill
bacteria and virus effectively 90~99.9%

Ozone has the
functions of dirty removal, bleaching and unpleasant smell removal, also can purify
washing water to reduce second polution.

Can do washing at
normal temperature water, reduce heating energy 60 ~90%

Reduce chemical 40~85%

Reduce water consumption
25% ~ 75%

Reduce washing time
20~30%

Reduce clothes wearing
and chlorine hurt, extend clothes life

Unlike normal
washing, the clothes is neutral but not light alkaline, more comfortable

Good news and bad news

Good news, Wan gave me a bottle of brined vegetable made by herself ! The taste is good!

Bad news, the bottle cap sealed not so good, it is leaking!  Oh, the brined vegetable smell full of my car! Crying face 

It seemed that need to clean and disinfect the car this weekend, its time to trying this, I left one sample in my home!Open-mouthed smile  Wink
