Algaecides for Surface Treatment and Water Treatment Plants

Algaecides for Surface Treatment

Algae is a growing problem in many water systems, and controlling growth with conventional algaecides just isn’t cutting it anymore. ATS Innova is proud to provide two alternatives to traditional products that are more effective at controlling algae, better for the environment, and better on the wallet—EarthTec®, Mainstream 635™, Lake Guard™ Oxy®, and Lake Guard™ Blue®. EarthTec, Mainstream 635, and Lake Guard Blue utilize biologically-active copper ions that doesn’t contribute to copper build-up, and Lake Guard Oxy uses sodium percarbonate—perfect for copper sensitive environments.

Mainstream 635

Many water systems struggle when high levels of algae and organics creep into their source water. These uninvited guests wreak havoc on the treatment plant and cause difficulty allowing water systems to meet their state and federal regulations and can render recreational bodies of water unusable. Worse yet, when organics are combined with chlorine, the resulting Disinfection By-Products (DBPs) can make water quality even worse.

It’s simple: Algae & Organics + Chlorine = Increased DBPs.

A Dissolved Copper Solution with a Low pH

Mainstream 635 has a very low pH value—coming in at 0.5. The low pH helps protect the biologically active cupric ions (Cu++) and allows for self-dispersal for an even distribution. This protection allows the Cu++ to stay active longer in its soluble form. Cu++ is the only form of copper that is useful in controlling algae. Dosage rates will be dependent upon biological demand and can be adjusted based on the time of year and concentration of organics. The low pH will assist in breaking down the organic material in a wide variety of water conditions and will not precipitate out of solution.

Case in Point

Manila Pond, Pleasant Grove, Utah

Concerned about the rapid increase of algae in a local pond, city officials reach out to ATS Innova for a solution. The Utah Fish and Game officers warned the city about the copper-sensitive trout and feared the impact on the local fish populations would be devastating. Despite this dilemma, the city decided to pursue treatment with ATS Innova and arranged for workers to clear the pond of dead fish twice a day, every day during the duration of the dosing.

At the end of the treatment process, the pond saw the elimination of its algae problem. But they saw something else: a distinct lack of dead fish. Over the entire dosing process—in which most of, if not the entire population was expected to die—there was not a single trout death. ATS Innova continues a low-dose Mainstream 635 treatment at the pond. This maintains water clarity, and the level of copper used in this dose is far below the toxic limit for any of the aquatic life the city wants to preserve.

Mainstream 635 is certified to NSF Standard 60 and rated for drinking water and is safe for humans, animals, and fish. Mainstream 635 is a low-pH copper tetra-hydride product and is highly effective against algae and bacteria.

Herriman city officials closed Blackridge Reservoir, a beautiful recreational lake set against Utah’s Oquirrh Hills, on Thursday August 6, 2015 after algae had proliferated and discolored the water. ATS Innova began treatment with EarthTec over that weekend, and by Monday August 10, the park and reservoir were once again open to the public.

Impressed with the turn-around, Sen. Mike Lee, R-Utah, met with ATS Innova president and CEO Richard Allred about additional roll-out and future clean-up projects. Read the Deseret News article here.

EarthTec

Copper Sulfate Alternative

EarthTec is a highly soluble low pH algaecide designed for use in lakes, ponds, reservoirs, sedimentation basins, irrigation canals, treatment lagoons, and other water systems, The active ingredient in EarthTec is a highly biologically active form of copper ion (Cu++). EarthTec contains a unique hydrotrope that results in a greater concentration of these ions under varying water conditions.

Critical Benefits from Proprietary Formulation

Because of its unique proprietary formulation, EarthTec treats differently in three important ways:

  1. EarthTec is 99.99 percent biologically available and is highly effective against algae and bacteria while remaining virtually harmless to aquatic life.
  2. EarthTec will remain suspended in the water until it is fully consumed by algae and bacteria—that means EarthTec will not precipitate out as bottom-settling sludge and contribute to dangerous copper build-up in the environment.
  3. EarthTec will evenly distribute itself throughout a given body of water—that means no mixing is required.

Case in Point

Private pond, Salem, Utah

In early May 2018, owners of a private pond in Salem, Utah reached out to ATS Innova to address a build-up of filamentous algae. Although filamentous algae are not toxic, they can form a mat on the surface and limit the amount of oxygen and light that reaches the water. Left untreated, the pond could begin producing noxious odors, and the population of largemouth bass could be eliminated, not to mention the pond’s aesthetics and the risks an algae mat poses to recreation.

ATS Innova began dosing the pond on Tuesday May 8 with EarthTec. By Monday May 14—only six days later—the pond was clean and free from the problematic algae mats that had plagued it previously. The result speaks for itself. In addition to the largemouth bass with which the owners stocked the pond, many varieties of mammals, birds, insects, and aquatic life were shielded from the threat posed by algae mats. The owners were pleased with the results and could relax knowing their local ecosystem was protected. 

EarthTec is registered by the US EPA as an algaecide and bactericide and is certified to NSF Standard 60 as an addition to drinking water. Even though EarthTec attacks and kills algae, bacteria, and zebra and quagga mussels, it remains safe-rated for drinking water and is safe for humans, animals, and fish.

Algaecide Innovation at Work

Lake Guard Blue and Lake Guard Oxy from Israeli company Blue Green Water Technologies has been used in Israel, China, South Africa, and the US to address dire algae and cyanobacteria problems. Blue Green Water Technologies focus on pairing field-tested, market-approved algaecide technology with novel delivery mechanisms that enables complete permeation and total coverage. These algaecide innovations thus remove all pre-existing limitations of feasibility, affordability, and eco-friendliness. Lake Guard Blue and Lake Guard Oxy are designed to solve most algae problems in reservoirs, lakes, ponds, and other bodies of water. 

Lake Guard Blue is a copper sulfate pentahydrate algaecide that is registered with the EPA and is certified to NSF/ANSI 60. Because of its proprietary delivery mechanism, application can be performed manually from the bank, a boat, or from an airplane—depending on the total area of the water body and the optimal application strategy—and it does not require a full lake application, which makes for a very short lead time with effective cover.

Conversely, Lake Guard Oxy is a sodium percarbonate algaecide that is registered with the EPA and is certified to NSF/ANSI 60. When dissolved in water, sodium percarbonate breaks down into hydrogen peroxide (which eventually breaks down to water and oxygen), sodium cations, and carbonate. That makes Lake Guard Oxy perfect alternative of copper-based algaecides, making it ideal for delicate water systems and areas sensitive to copper. Like Lake Guard Blue, Lake Guard Oxy can be applied by hand, by boat, or by plane and will permeate and provide complete coverage in a fraction of the time it takes to apply other algaecides—all thanks to the proprietary delivery mechanism developed by Blue Green Water Technologies. 

Case in Point

Nitzanim Reservoir near Ashkelon, Israel

Israeli water associations operate some 600 reservoirs all over the country to retain and manage recycled wastewater for irrigation. Cyanobacterial outbreaks occur regularly in these reservoirs due to high levels of nutrients, high temperatures, and sun light intensity. Over the years, these irrigation ponds have been continuously treated with raw copper, applied either from crop-dusting airplanes or manually from a boat. This treatment method was not effective and demanded frequent retreatment.

In many cases, the superintendents are forced to open and clean up pumps and filters on a daily basis to maintain the water flow. Eventually, as water levels decreased towards the end of the irrigation season, most reservoirs are forced to stop water flow entirely due to the condensed bloom clogging and sustained pump damage.

Figure 1. Seasonal treatment with Lake Guard Oxy and Lake Guard in an irrigation reservoir near Kibbutz Nitzanim, indicating the dramatic impact of the treatment on algal levels, its prolonged effect, and its ability to influence species-variety in favor of non-toxic ones (1kg/ha. ? 1lb/acre).

An initial treatment with Lake Guard Oxy, with subsequent treatments of Lake Guard Blue (as specified in Figure 1), was started in early 2018 and quickly caused the total collapse of the toxic bloom, keeping it below dangerous levels for months to-come. Prior to treatment, a mix of toxic cyanobacteria species (Anabaena sp. and Microcystis sp.) constituted over 95 percent of the entire phytoplankton population. Analysis of the phytoplankton population during and after treatment showed that the toxic dominant species were severely affected by the treatment (see Fig. 1.)

Analysis also showed smaller non-harmful eukaryotic algae species were left relatively unaffected and were allowed to occupy the so-called “vacant” ecological niche. In principle, these non-toxic species of algae should be welcomed as a natural buffer to toxic species; nevertheless, these non-toxic algae were clogging filter pumps and causing problems as well. Treatment was conducted once again to eradicate these species and eliminate these clogging issues. 

Copper Reduction and Key Takeaways at Nitzanim Reservoir

Despite toxic blooms that were worsening and intensifying year-over-year, the overall amount of copper applied in 2018 using Lake Guard was one third of that used in the year before. Considering the nearly 200 percent yearly rise in cyanobacteria populations in comparable water bodies in Israel between 2014-2017, the actual reduction in copper applied in 2018 using Lake Guard is closer to 85 percent.

A simple, cost-effective treatment with small doses of Lake Guard eliminated one dominant toxic species and enabled non-harmful, beneficial phytoplankton species to occupy the ecological niche, outcompeting the toxic cyanobacteria throughout the entire season. The dramatic shift between the toxic species to non-toxic ones has been seen in Lake Guard treatments throughout the world. Reshaping the balance of species in the water essentially restarts the disrupted ecological sphere and allows it to keep a healthy balance between these coexisting species in the water without subsequent intervention.
