Using sophisticated microscopy and computational analysis, Texas A&M University researchers have now validated the merit of a water purification technology that uses electricity to remove and inactivate an assortment of waterborne viruses. They said the yet-to-be-implemented water purification strategy could add another level of safety against pathogens that cause gastrointestinal ailments and other infections in humans.

“There is always a need for new techniques that are better, cheaper and more effective at safeguarding the public against disease-causing microorganisms,” said Shankar Chellam, professor in the Zachry Department of Civil and Environmental Engineering. “The water purification technique investigated in this study is a promising strategy to kill even more viruses at the earliest stages of water purification.”

The researchers have detailed their findings in the journal Environmental Science & Technology.

Before water reaches homes, it undergoes multiple purification steps, namely coagulation, sedimentation, filtration and disinfection. Conventional coagulation methods use chemicals to trigger the clumping of particles and microbes within untreated water. These aggregates can then be removed when they settle as sediments. While effective, Chellam noted that the chemicals used for coagulation could be very acidic, making their transport to treatment plants and storage a challenge.

Instead of chemicals-based coagulation, the researchers investigated if an up-and-coming coagulation method that uses electricity was as effective at removing microbes from water. In particular, they used a surrogate of a nonenveloped virus, called MS2 bacteriophage, for their study. Their choice of microbes was motivated by the fact that MS2 bacteriophage shares structural similarities with many nonenveloped viruses that can persist in the water after treatment and cause disease in humans.

For their experiments, the researchers inserted iron electrodes in a sample of untreated water laden with viruses. When they passed electrical currents, the anode oxidized, releasing iron ions into the solution. These ions combine with dissolved oxygen to produce hydroxyl radicals and also iron-rich precipitates. In the process, they found that as the iron precipitated, the virus attached to these clumps to form bigger aggregates, which could be easily removed from the water.

Next, they investigated if this process also inactivated the virus. But while the iron aggregates helped in capturing the virus, they presented a problem to picture inactivation using electron microscopy.

“Clumping causes a tremendous challenge because there is no easy way to isolate the virus from the iron-rich aggregates, making it difficult to visualize viral damage and analyze if electrocoagulation was the cause of the viral damage or the virus extraction from the iron-rich clumps,” said Anindito Sen, a research scientist at the Texas A&M Microscopy and Imaging Center.

To address this problem, Chellam’s graduate student Kyungho Kim with Sen’s guidance developed a novel computational technique to directly image the viruses aggregated alongside iron. Put briefly, they digitally inflicted damages on 3D images of an intact MS2 bacteriophage. Then they generated 2D versions of the damaged 3D model. Last, they compared these images with 2D microscopic images of the virus obtained after electrocoagulation.

The researchers found that the damage in electrocoagulated viruses ranged from 10% to greater than 60%. Further, by following the same analysis with bacteriophages isolated from conventional coagulation, they observed that the viruses were not inactivated.

“The traditional multistep process of water purification has been there to ensure that even if one step fails, the subsequent ones can bail you out — a multiple barrier approach, so to speak,” Chellam said. “What we are proposing with electrocoagulation is process intensification, where coagulation and disinfection are combined within a single step before subsequent purification stages, to ensure better protection against waterborne pathogens.”

This study is funded by the National Science Foundation.

Jothikumar Narayanan from the Centers for Disease Control and Prevention also contributed to this research by demonstrating genomic damage in the virus caused by electrocoagulation. The microscopy results in the study were confirmed with enumerations of infective viruses by traditional cell culture techniques, spectroscopy and genomic analysis.

In doing so, we produce high quality water which can be reused for agricultural irrigation, discharged to the city at reduced fees, or...


Industrial wastewater treatment requires appropriate technologies as well as proper application. After performing a full system audit and all requisite testing, ChemTreat can customize a wastewater treatment process that optimizes chemical usage, effluent flow rates, and off-site treatment costs. We provide environmentally-efficient and sustainable treatment methods for effluent systems. We also have expertise in water reuse systems and zero-liquid discharge. ChemTreat will select the optimal organic and inorganic chemicals to reduce your discharge costs and optimize your effluent system.

Our wastewater specialists have experience with unique wastewater treatment processes for industries such as metals, oil and gas, automotive, food and beverage, mining, steel manufacturing, and pulp and paper processing.

ChemTreat has a full product line for foam reduction and elimination in industrial water systems, and can provide a defoaming agent best-suited to optimize your system.
We provide defoamer technologies to eliminate foam in boilers, cooling towers, and effluent systems, and ensure smooth operating conditions. The most common of these defoaming agents are surface tension reduction and bubble-wall destabilization products. Defoamer products consist of silicone, oil-based, ester-based, water-based, and polymeric constituents.

Oil Removal
Our chemical treatment programs offer a complete portfolio of surfactants, coagulants, and emulsion flocculants typically used in oil removal applications.
ChemTreat’s chemical treatment programs offer a complete portfolio of emulsion flocculants, which are suspensions of minute beads of high-molecular-weight polymer in water, emulsified in an oil carrier. The minute beads are approximately 1 micron in diameter and contain concentrated polymer dissolved in water. These concentrated polymer beads, or “hydrogels,” are dispersed in a carrier fluid of high-flashpoint mineral oil by means of a dispersing surfactant that keeps the hydrogels from coalescing into larger droplets. Because the hydrogels are of greater density than the carrier oil, they are prone to settle over time, resulting in concentrated polymer solids on the bottom of the container with a layer of oil on the top. This separation can develop faster if the droplets are large, so keeping the droplets small and well-dispersed is important in maintaining the product stability.

Emulsion flocculants are typically copolymers of acrylamide, a nonionic building block, and a charge-bearing monomer. In the case of anionic flocculants, the anionic charge is produced by co-polymerizing acrylic acid with the acrylamide monomer. The ratio of acrylic acid to acrylamide determines the degree of charge on the molecule.

In the case of cationic flocculants, the cationic charge is provided by co-polymerizing AETAC, a methyl acrylate-derived cationic monomer with the acrylamide monomer. The ratio of AETAC to acrylamide determines the degree of charge on the molecule.

Because the hydrogels are made up of tightly-coiled polymer chains, mixing energy and time are required to ensure full contact of the hydrogels with the water to enable the polymer chains to uncoil fully. The polymer chains may be cationic, anionic, or nonionic with varying charge weights. The charge on the chain helps uncoil the chain, so a higher-charged polymer will open faster than a low-charged or uncharged polymer.

Metals Removal
We offer a full range of products for wastewater heavy metals removal. Our treatment programs are effective in all discharge pH ranges and result in treatment time and chemical usage savings.
A heavy metals removal program is necessary to ensure proper adherence to site discharge requirements for constituents such as iron, lead, copper, chromium, nickel, and manganese. These contaminants can enter wastewater streams from a variety of industrial processes, and if untreated, are toxic to the environment and living ecosystems. In recent years, many regulatory agencies have tightened discharge requirements for customer sites, and continue to monitor discharges to POTWs and the environment.

Odor Control
We provide a complete line of odor-masking agents and neutralizers, including hydrogen sulfide scavengers and absorbents, to reduce or eliminate noxious odors regardless of the source.
Are there odors in your water? Odors result from the presence of volatile organic compounds such as hydrogen sulfide and ammonia, which readily evaporate into the surrounding air. There are several industries where wastewater odor control is necessary, such as paper, refining, natural gas separation and purification, industrial wastewater treatment, and animal and food processing. These odors can be reduced or eliminated by using operational, mechanical, or chemical treatment technologies, but severe odors often require a combination of several technologies.

Air stripping is an affordable and reliable wastewater odor control solution where the contaminated water is exposed to a countercurrent flow of air in a packed tower. The air strips out the VOCs and is either discharged or treated. An important component of using air strippers for industrial odor control and pollution is pretreatment. For example, wastewaters with high ammonia levels often require a pH adjustment prior to stripping to optimize performance. Additionally, the presence of iron, manganese, and bacteria in a water source will lead to scale and fouling within the air stripper, reducing the effectiveness of the system and other equipment. In some systems, calcium carbonate scale can also be a problem. ChemTreat offers assistance in reducing or eliminating air stripper fouling through the use of specialty chemicals, including iron and manganese stabilizers, scale inhibitors, and biocides.

Air strippers are also critical for health and safety as they can be used to remove hazardous air pollutants such as benzene, toluene, ethylbenzene, and xylene.

Sometimes waters that emit odors can be chemically treated without the use of an air stripper. ChemTreat provides a complete line of odor neutralizers, including hydrogen sulfide scavengers and absorbents to reduce or eliminate noxious odors regardless of the source.

ChemTreat quickly implements a program to solve odor control problems at a wastewater facility.

PUREFloc™ Coagulants
PUREFloc coagulants are naturally occurring polymers that function similarly to synthetic organic coagulants such as polyDADMACs and polyamines. However, they are much more effective for oil removal from water or wastewater. They can also be used to replace or reduce the use of inorganic metal salts such as polyaluminum chloride (PAC), aluminum chlorohydrate (ACH) and aluminum sulfate (Alum).
PUREFloc products can be utilized alone or in conjunction with traditional inorganic metal salts.

These coagulants have been successfully applied in water clarification for the Food & Beverage, Primary Metals, Automotive, Mining, and Oil & Gas industries.

Benefits over synthetic coagulants and inorganic salts typically include:

Typical coagulant usage rate reduction of 25% or more
Overall reduction of chemical use cost
Higher oil reduction rates
Low handling hazard and corrosivity
Reduced sludge volumes
Lower chlorides and sulfates

NGWA President Is Featured in CNBC News Story on Water Dowsing

NGWA President Merritt Partridge was featured in a news story that aired on August 19 on cable channel CNBC that discussed the increase in water dowsing/water witching taking place in California due to the state’s extended drought.NEW merritt

Water dowsing, also known as water witching, is a method of using a forked stick, rod, pendulum, or similar device to locate groundwater. NGWA has long been opposed to the practice — citing the technique is totally without scientific merit.

The CNBC segment aired on the primetime show, The News with Shepard Smith. Guest anchor Tyler Mathisen began by saying the drought is causing people to turn to unconventional means of finding water that some say are disputed ways.

The segment interviewed a dowser who said he was extremely busy, a vineyard owner who said he has used the dowser several times, and Partridge who stressed the importance of science and data when assessing water availability.

Partridge, the president of Partridge Well Drilling Co. Inc. in Jacksonville, Florida, was shown in front of a drilling jobsite and said: “I can understand in desperate times (people) might look for resources that improve their chances, but the facts are that using science and data to find (water) is going to provide more accurate results.”

The segment follows a New York Times story on July 17 regarding the reported increase in water dowsing in California. In it, NGWA Scientist and Engineer Section Director Timothy Parker, PG, CEG, CHG, of Sacramento, California, cited that hydrogeologists and water well contractors use a combination of satellite imagery, geology, and drilling data to assess water accessibility and resources, “compared to dowsing, which is a person with a stick.”
