New Cooling Tower Maintenance Law Update Effective May 9Th For Nyc!
The best pre-treatment for water is a matter of what?s required of the water. If you?re intending to release it back into the environment, there are laws and homepage standards to attend, and for other destinations or applications, water will have differing properties. The means by which you want pre-treatment applied to your water should be the best process by which the most desirable water is achieved.
Many water companies provide filters or resins for pretreatment, though this can be regarded as an incomplete approach. Any business or institution that?s going to invest in an ideal form of water pre-treatment would benefit from consulting experts to evaluate whether or not the apparatus in place is ideal. Often, they can be improved upon, as water technology is an active science.
If a water company is going to offer you pre-treatment water solutions, you would be best served by one that offers solutions that include optimizing your existing apparatus. An engineer with a background in water technology is what?s required here. If your existing apparatus proves to be ideal for the task at hand, that?s valuable information. So is knowing about the areas of opportunity in your system as explained by a seasoned professional.
If you?re in Etobicoke, Ontario, or in the surrounding areas, and you have a pre-treatment water process that requires attention, we at Ion Water Solutions can offer comprehensive assistance. With our backgrounds in chemistry and engineering, we offer holistic solutions to water technology issues so that your pre-treatment process will be ideal.

Hot Summer Days and Even A Dirty Evaporator Coil Mean Big Headaches
Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters.
"We are not trying to treat the entire hydrocarbon [oil] content in the water ? to turn it into carbon dioxide and water ? but we are converting it into a form that can be retained by sand filtration, which is a conventional and economical process," says Andy Hong, a professor of civil and environmental engineering.
In laboratory experiments reported online in the journal Chemosphere, Hong demonstrated that "pressure-assisted ozonation and sand filtration" effectively removes oil droplets dispersed in water, indicating it could be used to prevent oil sheen from wastewater discharged into coastal waters.
Hong says the method ? for which patents are pending ? also could be used to clean a variety of pollutants in water and even soil, including:
- So-called "produced water" from oil and gas drilling sites on land. Such oily water normally is re-injected underground. "If we have technology to clean it, it could be put into beneficial uses, such as irrigation, especially in arid regions where oil and gas tend to be produced," says Hong.
- Water from mining of tar sands and oil shale.
- Groundwater contaminated by MTBE, a gasoline additive that reduces harmful vehicle emissions but pollutes water due to leaking underground gasoline storage tanks.
- "Emerging contaminants," such as wastewater polluted with medications and personal care products.
- Soil contaminated with polychlorinated biphenyls (PCBs, from electrical transformers) or polycyclic aromatic hydrocarbons (PAHs, from fuel burning). Water and contaminated soil would be mixed into slurry, and then treated with the new method.
- Heavy metals in soil. Instead of ozone, air and metal-grabbing chelating agents would be pressurized with a slurry of the contaminated material.
- Refinery wastewater and oil spills at refineries or on waterways. The spill could be vacuumed, and then treated with the new method on-site or on a barge.
Hong conducted the study with two University of Utah doctoral students ? Zhixiong Cha, who has earned his Ph.D., and Chia-Jung Cheng ? and with Cheng-Fang Lin, an environmental engineering professor at National Taiwan University.
Zapping Oily Water with Microbubbles from Ozone under Pressure
Hong says his method uses two existing technologies ? ozone aeration and sand filtration ? and adds a big change to the former. Instead of just bubbling ozone through polluted water, Hong uses repeated cycles of pressurization of ozone and dirty water so the ozone saturates the water, followed by depressurization so the ozone expands into numerous microbubbles in the polluted water, similar to the way a carbonated beverage foams and overflows if opened quickly.
The tiny bubbles provide much more surface area ? compared with larger bubbles from normal ozone aeration ? for the oxygen in ozone to react chemically with oil. Hong says pollutants tend to accumulate on the bubbles because they are not very water-soluble. The ozone in the bubble attacks certain pollutants because it is a strong oxidant.
The reactions convert most of the dispersed oil droplets ? which float on water to cause sheen ? into acids and chemicals known as aldehydes and ketones. Most of those substances, in turn, help the remaining oil droplets clump together so they can be removed by conventional sand filtration, he adds.
In his study, Hong showed the new method not only removes oil sheen, but also leaves the treated water so that any remaining acids, aldehydes and ketones are more vulnerable to being biodegraded by pollution-eating microbes.
"These are much more biodegradable than the parent compounds," he says.
Hong says the water is clean enough to be discharged after the ozonation and sand filtration, but that some pollution sources may want to use conventional methods to biodegrade remaining dissolved organic material.
Details of the Experiments
Hong conducted his experiments using a tabletop chemical reactor that contained about a quart of oily water made by mixing deionized water with crude oil from the Rangely oil field in northwestern Colorado.
Ozone was produced by passing dry air through a high-voltage field, converting oxygen gas, which has two oxygen atoms, into ozone, which has three.
The ozone was pressurized to 10 times atmospheric pressure, about 150 pounds per square inch, web page which compares with inflation pressures of about 100 PSI for Hong's bicycle and 35 to 40 PSI for many automobile tires.
He found oily water was cleaned most effectively by pressurizing and depressurizing it with ozone gas 10 times, then filtering it through sand, then putting the water through 20 more pressurized ozone cycles, and then filtering it again through sand. That was at flow rates of 10 to 20 liters per minute [about 2.6 to 5.3 U.S. gallons per minute] in his laboratory apparatus.
Hong tested how well the ozonation worked by measuring chemical and biological oxygen demands of treated water samples. Both indirectly measure organic contents in the water. Hong also used mass spectrometry to identify what contaminants remained in the water.
He found that his most effective procedure removed 99 percent of the turbidity from the "produced water" ? leaving it almost as clear as drinking water ? and removed 83 percent of the oil, converting the rest to dissolved organic acids removable by biodegradation.
A Tryout in China
With success in the laboratory, Hong now plans for larger-scale pilot tests.
"It is economical and it can be scaled up," he says.
One such test will be done in Wuxi, China, where a prototype desk-sized device capable of treating 200 liters [53 U.S. gallons] at a time will be tested at three to five polluted industrial sites that the government vacated for redevelopment, Hong says.
Meanwhile, the University of Utah Research Foundation has entered into options to license the technology to Miracotech, Inc., of Albany, Calif., and 7Rev, L.P., a Salt Lake City venture capital group, so the companies can bring the technology to market.
Hong says other methods of treating oil well "produced water" have met with varying degrees of success. They include centrifuges, membranes, regular ozonation and air bubbles to float off contaminants. But all have drawbacks, such as inability to handle dissolved oil or high levels of oil, or susceptibility to quickly getting fouled by the oil.
Neither ozonation nor sand filtration alone has been able to effectively treat oily "produced water." Hong says long-chain oil molecules don't react with ozone easily without his pressure treatment. And sand filters alone cannot remove oil.
Are Your Boilers Running Without Automated Blowdown?
If you?re in the market for water pre-treatment, you know that cutting corners simply won?t work. With so many legal stipulations pertaining to water quality, finding a cut-rate solution simply isn?t in the cards; the government will bite you hard if you try. At the same time, accepting any answer without shopping properly for the best solution is also bad business. What you need is an optimal solution that is both profitable and legal.
In order to realize this balance, you need a water technology company that takes into account all the aspects of the apparatus supporting the inflow and outflow of water for your business or institution. It?s not enough to simply have a chemical expert examine your water for variations at different points in your production line; you also need an engineer?s eye to go over your production site to ensure that the production apparatus will support the best possible water pre-treatment process. If both your chemical solutions and apparatus solutions are set up together ideally, then you?ve got an optimized production line.
If you?re in Etobicoke, Ontario or in the surrounding area and in search of an optimal water pre-treatment solution, we at Ion Water Solutions can help. Our expertise is in both the fields of chemistry and engineering. This, combined with our enthusiastic expertise in water technology, allows us to provide you with the best opportunity to optimize your water pre-treatment system.

The Aries Linden Biosolids Gasification Facility will be located in a re-purposed building within the Linden Roselle Sewerage Authority (LRSA) complex, 20 miles from Manhattan (New York City). Aries will deploy its patented fluidized bed gasification system that was designed specifically for processing biosolids. The system will reduce the volume of biosolids from 400 tons per day to 22 tons of beneficial biochar. The biochar will be beneficially used as a substitute for fly ash in concrete. The renewable energy that is generated from the system is then recovered and used within the system, so no fossil fuels are used during normal operations. It will also reduce greenhouse gases due to the reduction in trucking miles associated with conventional disposal methods as well as the elimination of methane generated from land application of biosolids.
?With these approvals, this marks the first large-scale fluidized bed gasification system to process biosolids in the world,?? said Gregory Bafalis, CEO of Aries Clean Energy. ?Aries patented gasification system eliminates the need for environmentally harmful landfilling or incineration of biosolids, while producing beneficial renewable energy and biochar. We believe this truly is a beneficial and disruptive technology that will revolutionize the wastewater treatment industry and establish itself as the best available control technology for biosolids disposal.??
?It has been a great experience to team up with the LRSA and the State of New Jersey Department of Environmental Protection (NJDEP). The awarding of these permits further validates Aries patented technologies will bring clean and renewable solutions not only to the Garden State, but worldwide,?? Bafalis added.
?We are excited to bring this green gasification technology to Linden. It?s more than the addition of jobs to our City, it?s taking a step toward a healthier New Jersey, a healthier Earth,?? said Mayor Derek Armstead, mayor of Linden, NJ. ?This is not only a first for Linden, but it will be the largest facility of its type in the world.??
The Mayor went on to further state, ?On behalf of the residents of Linden, we look forward to a long relationship with Aries Clean Energy. Its proven technology will provide a biosolids disposal solution that helps the environment and saves taxpayers money.??
LRSA, created in 1948, services the City of Linden and the Borough of Roselle. It was established to contract and operate wastewater treatment and interceptor facilities to collect, treat, and dispose of sewage generated by the municipalities.
