STANDISH, Maine (NEWS CENTER) — Portland Water District admits they do have aging pipes, but say they take a lot of steps to ensure clean water travels to their customers.

The lead-tainted water crisis in Flint, Michigan has now attracted the attention of the United Nations, and has more people second-guessing what’s in their water.

The water crisis began when Flint’s water became contaminated with lead from aging pipes when the city switched from Detroit water to the Flint River in 2014 to save money. Some children’s blood has since tested positive for lead, which is linked to learning disabilities.

Here in Maine, crews work hard to make sure drinking water is safe.

The water treatment facility for Portland and its surrounding towns sits in Standish next to Sebago Lake. There, millions of gallons of water is pumped with disinfectants, filtered, then treated with a combination of additives that make the water less corrosive on the hundreds of miles of piping.

“With the people we have working here and the systems we have in place, all those are to safeguard water quality so when our customers turn on their tap in the morning take that drink of water, they can feel assure that’s a safe product,” said Mike Koza, the lab director at the water treatment facility.

That assurance starts with Sebago Lake, one of the cleanest reservoirs in southern Maine. Millions of gallons of water is pumped into massive tanks, where generators create ozone, generating a charge that kills bacteria. From there, the water runs through U-V lights, before chlorine, fluoride, and additives that prevent corrosion as the water travels through the pipes, are all added.

Joel Anderson, the chief operator of the treatment facility says everything is monitored 24/7, and then tested in their lab. Each month the lab also tests more than 150 samples from the field to ensure the quality of the water remains when it makes it to the taps of homes and businesses.

The Portland Water District also spends about $7-million dollars every year upgrading pipes that were installed decades ago.

Oxidation Potential of Ozone

oxidation porential of ozone

What is Oxidation?

Oxidation is a chemical reaction in which electrons are LOST by atoms, ions or molecules. Reduction is the GAIN of electrons. Regardless of the name similarity, oxidation reactions need not actually involve oxygen atoms or molecules.

Oxidation, for non-chemists and those who have forgotten high school chemistry, is commonly just burning or rusting. If done instantaneously, it is an explosion. If done rapidly, it is burning. If done slowly, it is corrosion. When acting at a molecular level, it is just plain oxidation, or part of the oxidation-reduction process. It can occur in gaseous or solid states as well as in liquids.

 

Ozone has one of the highest oxidation potentials, lower only than flruorine atom, oxygen atom, and hydroxyl radical.  Some of the reactions of ozone create the oxygen atom and hydroxyl radical to create an even higher oxidation potential than ozone alone.

Because of the high oxidation potetnail the oxygen molecule has a high capacity to react with many compounds not easiy oxidized by other chemicals.  This potential is especially important reactions with some inorganic species such as FE+2  and I-.  However, in many cases there is no explicit electron transfer, but rather an oxygen transfer from the ozone molecule to the other compound.  

Example of ion exchange oxidation of ozone and iron:

Fe+2 + O3 = FE+3 + O3-

Example of oxygen atom exchange oxidation of ozone and iron:

2Fe2+ + O3 + H2 O → 2Fe3+ + O2 + 2OH-

Both reactions can occur with organic and inorganic compounds.  This is just one simple example of ozone oxication reactions.

Ozone used for bacterial reduction in drinking water

City of Oregon, OH turns to ozone to treat drinking water.  According to city officials ozone was a better technology for bacteria reduction.

 

Ozone helps protect the earth’s surface from harmful ultraviolet rays, but Oregon is using it to combat something else.

In an effort to ensure the safest drinking water possible, the city’s water treatment plant has gone ahead with plans to use ozone to eliminate harmful bacteria, including cyanobacteria that produce microcystin.

“Ozone treatment is really the emerging, best practice to deal with surface water,” Oregon city administrator Michael Beazley said.

Oregon was not affected by Toledo’s water ban in 2014, but the crisis was an eye-opener, prompting research into this new technology.

The city’s water intake is in Lake Erie, but it is separate from Toledo’s. When lake water reaches the Oregon’s treatment plant, ozone combines with electricity to break up any organic contaminants in the water into smaller pieces. What’s left goes through biological filtration. The system kills algae-related toxins in about eight-tenths of a second.

“Once you get ozone added into the treatment, you’re going to eliminate any chance of microcystin getting into the tap water,” said  Doug Wagner, superintendent of water treatment. “[The algae problem] isn’t going to go away, so we’re going to hit it head-on.”

The plant ran a pilot program from July to November. During the program, crews used the ozonation process to treat four gallons of water per minute, sent it through the contact chamber, and put it in a biological filter.

“It was like a microplant,” Mr. Wagner said. “We had four columns that had different filter profiles in each one to put the ozonated water through to see which one would grow the best bacteria that would consume the organics in the water.”

The new system, which is expected to be in place by the 2017 algae season, should lower the amount of chlorine used in drinking water, officials said. Ozone is a better disinfectant and produces fewer disinfection byproducts, known as trihalomethanes. It also eliminates a higher number of trace organic compounds, officials said.

“By reducing the amount of chlorine we use, we end up with water that is safer, more easily treated, has a better taste to it, and end up without some of the by-products you end up with using chlorine treatment,” Mr. Beazley said.

After the ozone disinfects the water, it turns back into oxygen. All water leaving the plant will be ozone-free.

The entire project is expected to cost about $14 million, funded mostly by a zero-interest loan of about $750,000 a year for 20 years from the Ohio Environmental Protection Agency’s Water Supply Resolving Loan Account. The city also secured a $1.4 million grant from the Ohio Public Works Commission.

Oregon’s water rates will increase slightly over a period of time. The average customer will pay about $2 to $3 more a month, city officials said.

Mr. Beazley said bids for construction submitted in December  are being reviewed, and a contract should be awarded in the next few weeks.

Ozone used to treat potable water

Vietnam potable water treatment plant expansion includes ozone treatment

Vietnam potable water treatment plant expansion includes ozone treatment

Xylem has secured a $1.3 million contract to provide advanced treatment technology to the Saigon Water Corporation’s Tan Hiep Water Treatment Plant 2 in Vietnam’s capital, Ho Chi Minh City.

Under the contract, Xylem will design, install and commission an expansion of the existing treatment plant, to include the first ozone treatment application in Vietnam.

The upgrade will enable the plant to produce 300,000 m3/day of drinking water for 1.5 million Ho Chi Minh City inhabitants.

The company’s Leopold Type S Underdrain and Wedeco SMOevo ozone system will be used to increase the capacity of the Tan Hiep Water Treatment Plant 2.

Construction on the project upgrade began in Q4 2015 and the plant is expected to be operational by April 2016.

Ho Chi Minh City relies largely on rivers for its public water supply; raw water is taken from the Dong Nai and Sai Gon rivers, both of which are polluted by discharges from residential areas, hospitals, factories, waterway transport vessels, farms, and even garbage dumps, Xylem said.

Truong Khac Hoanh, CEO, Saigon Water Corporation, said: “The Tan Hiep Water Treatment Plant 2 has a key role to play in ensuring the residents of Ho Chi Minh City have access to a clean water supply.”

Ozone therapy: A revolutionary beauty technique

As we get older, the signs of aging begin to appear and our skin loses elasticity. However, Ozone Therapy, a new treatment technique, has come to the rescue as it helps to prevent the early signs of maturing and keeps skin glowing without cosmetic intervention.
We met up with Dr. Nada Alaaeddine, a specialist in regenerative medicine at Beirut’s Innovi Cell Therapy Clinic, to find out more about Ozone Therapy.

How can Ozone Therapy help?
Ozone Therapy stimulates the body to repair itself by using pure medical oxygen. A small amount of blood is taken from the client and Ozone 03 is added to it, in a sterile and concentrated manner, then it is injected into the body under the supervision of specialists. Ozone Therapy promotes blood circulation to carry renewed life to cells, increasing oxygen in every cell in the body and providing it with energy and vitality.
Since the treatment is a natural anti-oxidant, it eliminates viruses, bacteria and other impurities, and it contributes to healing many diseases, especially skin diseases. What’s more, it delays the signs of aging.

How is it performed?
There are two ways to perform Ozone Therapy, either through injections into the blood stream or through an ozone sauna, which has two phases. During phase one, in an equipped and sterile room, the client puts on an oxygen mask to stop the air inside the room fusing with the treatment and turning it into a toxic substance that could cause damage. Ozone Therapy is used to open the pores and to achieve cell renewal at a certain temperature, under the supervision of a doctor who specializes in the technique.
During phase two, the ozone sauna is completed with a massage using creams, especially made for each woman from stem cells in the laboratory.

Does this technology eliminate the signs of aging or prevent them from appearing?
This treatment fights aging from the inside, regardless of whether it shows deeply or superficially on the skin. The therapy works by getting rid of toxins in the body and invokes cell regeneration that reflects freshness on the skin and makes it more youthful. This technique does not eliminate wrinkles forever, but helps in delaying the signs of maturing.

Are there any side effects and is the technique scientifically proven?
Ozone Therapy is completely safe and without any side effects, it has been scientifically proven and has treated a number of diseases and skin cases. It is universally supported, particularly in Germany, Italy and Madrid. Many of those who have undergone this treatment have achieved the desired result and their skin has regained its glow and freshness, enabling them to enjoy a more balanced and youthful look. The effectiveness of this technique lies in fighting wrinkles by not allowing their early progress, or so-called premature aging.

How effective is it?
This treatment is described as incredible due to its ability to implant freshness and youth into skin after the first session. The effectiveness of this technique might vary from one woman to another, as it is affected by age, skin type and the number of sessions to get the desired result.

How many sessions should be done for an optimal result?
This depends first on your skin and how affected it is by the signs of aging, but preferably sessions should take place once every three months. The treatment is not costly and every woman can do it.

So can it be performed at any age?
Age does not play a major role in this procedure, but it is recommended for people above the age of 20.

Can men benefit from this technique as well?
Wrinkles are considered a major concern for women and men alike. Many men look after their appearance and resort to using this technique. The treatment is modern and sophisticated as it renews cells and maintains a glowing look.

Are there daily routines or a certain diet that must be followed post-treatment?
It is not necessary to adhere to a certain diet or exercise, even though this contributes to maintaining healthy skin.

Is it considered a substitute for Botox?
No, it is different from Botox in terms of composition and method of application. It is a natural protein substance extracted from a type of bacteria that works to remove wrinkles around the eyes and forehead by injections. Ozone Therapy works to stimulate cells and get rid of toxins in the body through the use of the ozone sauna or by blood injection.

Can you give a few tips to avoid looking older?
Women shouldn’t delay in solving skin problems and addressing them so they can protect themselves against premature aging. Keeping in shape is as important as looking after one’s health. An ideal and glowing look confirms a woman’s self-confidence.
