Wastewater Treatment Efficiency with BCL6000

It can be difficult to manage a wastewater treatment plant. Plant upsets may come without warning, and the naturally existing microbial colony may not be able to keep up with sudden influxes of heavy organic loading. Bionetix® International is here to help wastewater treatment plants bring effluent back into healthy balance and keep it that way through the automatic application of its new BCL6000™.

A Convenient Path to Better Wastewater Management

BCL6000™ is a blend of aerobic and facultative anaerobic microorganisms in liquid form. It is effective in degrading many types of waste and is especially convenient for ongoing maintenance because it can be applied by automatic pumping. BCL6000™ improves treatment plant performance while keeping odors, BOD, and foam in check. The main benefits can be summarized as follows:

  • Better effluent quality
  • Lower BOD
  • Fewer unpleasant odors
  • Reduced plant upsets from shocks
  • Improved sludge settling

How BCL6000™ Works

BCL6000™ combines multispore bacteria with free enzymes, nutrients, and a source of oxygen. Together, these components work to enhance the natural biodegradation capabilities of a wastewater treatment environment. Under normal wastewater conditions, standard biological treatment relies on existing microorganisms in the wastewater to digest waste compounds into small particles, biodegrading the effluent until it is safe to be released to the environment. However, sometimes a sudden influx of new waste materials can throw the microbe-to-organics ratio out of balance. This is represented by an increase in BOD (biological oxygen demand), a measure of the amount of oxygen needed to biodegrade the volume of organic waste present. High and low temperatures or limited oxygen can also upset normal wastewater treatment plant processes. Side effects of these problems may include unpleasant odors, foam, and greater sludge buildup over time.

Bioaugmentation and Biostimulation for Costs Savings

BCL6000™ helps bring the system back into balance by adding microbial reinforcements (bioaugmentation) and nutritional supplements (biostimulation) that improve the performance of those microorganisms. For example, enzymes help microorganisms speed up the digestion process. Nutrients encourage healthier microbial growth for more efficient reproduction and biodegradation, increasing the number of microbial “workers” in the wastewater. Having an oxygen source also ensures that the microorganisms can continue working even in low oxygen environments without immediately reverting to the high-odor process of anaerobic digestion. This greater efficiency also translates into less sludge buildup, decreasing the frequency of sludge dredging and saving significant costs.

Automatic Metering in Biological Units

After a plant upset, a shock dose of BCL6000™ is a great way to get the wastewater system back into balance. Thereafter, BCL6000™ is ideal for ongoing maintenance as a liquid product that can be automatically metered into the wastewater. BCL6000™ can be used in aerated, facultative, and anaerobic lagoon systems; trickling filters; rotating biological contactors; aerobic digesters; sequencing batch reactors; moving bed biofilm reactors; and other biological units.

A Reliable Workforce

Wastewater treatment plant management can be a difficult juggling act with many unpredictable and uncontrollable aspects. BCL6000™ can help smooth out those inconsistencies through bioaugmentation and biostimulation. In effect, dosing BCL6000™ is like having a steady stream of efficient workers to keep up with the extra workload. Contact Bionetix® to learn more about this great new bioaugmentation blend for healthy wastewater plants!

PRESS RELEASE: Get More Efficient, Comprehensive Corrosion Protection with VpCI®-707 Fuel Additive!

  By

August 7, 2023

VpCI®-707 Fuel Additive

Corrosion inside fuel tanks can lead to serious problems from leakage or corrosion products that clog the system. To make matters worse, the issue may be difficult to detect inside the hidden atmosphere. All too often, corrosion occurs in the headspace above the fuel where water condenses and fuel additives cannot reach. Cortec® VpCI®-707 changes that by delivering more comprehensive, efficient protection to the entire tank.

Cortec’s Newest Generation Fuel Additive

VpCI®-707 is Cortec’s newest generation fuel additive for protection of fuel systems from corrosion during operation, storage, or shipment. It effectively provides corrosion protection in the fuel system not only in direct contact with the treated fuel, but also in the vapor space above the fuel line. This is due to the presence of Vapor phase Corrosion Inhibitors that diffuse throughout enclosed voids and adsorb on metal surfaces as a protective molecular layer. VpCI®-707 also offers improved water handling and improved fuel stability.

How to Use VpCI®-707

The characteristics of VpCI®-707 make it suitable for day-to-day operation, intermittent operation, and storage. There are two main applications. One is to add VpCI®-707 directly to gasoline or diesel fuel in blending, storage, or vehicle tanks that are in use. This can be done at a dose of 0.02-0.2% per tank volume. Dry fuel storage tanks being shipped or stored can be fogged with VpCI®-707 concentrate, covering as much internal surface area as possible (although the vapors are also designed to protect surfaces to which it is not directly applied).

Fighting Corrosion on Tank Farms

Airports, gas stations, farms, and other facilities that have tank farms and/or store a large amount of fuel onsite can benefit from VpCI®-707 to minimize the amount of corrosion that occurs inside the tanks. Instead of relying on contact-only inhibitors, tank owners and managers can fight corrosion in all parts of the tank, including the vulnerable ceilings where moisture is more likely to condense and cause corrosion.

Corrosion Protection During Export

Another great use of VpCI®-707 is for the protection of fuel tanks in new trucks or heavy equipment being exported to other states or countries. During overseas transport, changes in temperature and humidity can cause condensation to build up inside the tanks, leading to corrosion by the time the equipment reaches its destination. Instead of opening the tank to find a shiny metal interior, the receiving workers may unscrew the fuel cap only to find corrosion spots inside—hardly the sight that manufacturers want customers to see on a new vehicle. One of the challenges with using traditional contact-only corrosion inhibitors is that the fuel tank must be filled as full as possible to get maximum protection. This can be dangerous and difficult during transport. It is often preferable to fill the fuel tanks with only enough fuel to drive the equipment up onto the flatbed or into the container and drive it off the trailer when it reaches the end user. VpCI®-707 makes this possible since it can be fogged into an almost empty tank to protect the entire void.

Other possible applications the following:

  • Equipment operating in harsh industrial or offshore environments
  • Generators or other equipment going into seasonal storage
  • Industrial plants going into temporary layup

Protect More with VpCI®-707

Fuel tank corrosion is nothing to play around with. The hazardous nature of fuel means that leakage should be avoided because of its polluting and flammable nature. VpCI®-707 helps by protecting areas of the tank that other corrosion inhibitors may not be able to reach and making it easy for manufacturers to leave less fuel in the tank during transport. Contact Cortec® to learn more about using VpCI®-707 in your application!

PRESS RELEASE: Improve Heat Exchange Efficiency with This Biobased Scale Remover!

  By

Scale and rust can build up over time in heat exchangers, chillers, cooling towers, and other circulating water systems—especially those that are not properly treated. Failing to prevent scale buildup leads to the need to either chemically or mechanically remove scale to maximize designed heat transfer efficiency, good pipe flow, and equipment integrity. One great way to do this is with EcoClean® Biodegradable Scale and Rust Remover Powered by Nano-VpCI™, a USDA Certified Biobased Product available from Cortec® Corporation.

biobased scale remover

Why Remove Scale and Rust?

Scale buildup does two things. It insulates metal surfaces and clogs piping. This makes equipment work harder to transfer the desired amount of heat and pump the water through the system. In extreme situations this can lead to equipment downtime and failures. Rust has similar effects and also represents the loss of metal and the potential for leakage and shortened service life. The situation only gets worse the longer it is neglected. Periodic scale removal every one to three years, or whenever an unexpected drop in heat exchange temperature is noticed, is a best practice for keeping scale and rust buildup under control and avoiding the extra costs, repairs, and other headaches associated with 10, 15, or even 20 years of accumulation.

Multi-Metal, Biobased Scale Remover from Cortec®

EcoClean® Biodegradable Scale and Rust Remover Powered by Nano-VpCI™ is a heavy-duty product that works quickly to dissolve heavy scale and oxides (rust/corrosion) off metals. Unlike some products that cannot be used on aluminum or stainless steel, it is safe to use on multiple metal types, making it flexible for many different materials encountered in water treatment applications:

• Carbon steel
• Stainless steel
• Copper
• Aluminum

EcoClean® Biodegradable Scale and Rust Remover Powered by Nano-VpCI™ contains 100% USDA certified biobased content and is easily biodegradable, giving it a positive environmental profile on two counts.

How to Remove Scale with EcoClean®

EcoClean® Biodegradable Scale and Rust Remover should be used regularly to avoid more serious problems in heat exchange systems. The product comes in three forms: liquid, powder, and water-soluble pouch. The liquid version should be added to water at a 1:2 ratio and, if desired, can be sprayed inside open tube bundles. The powder version can be added to water at 7% by weight and used in the same manner as the liquid. The pouch version is convenient for circulating systems and can simply be tossed in the water and allowed to dissolve and circulate for a few minutes without dismantling the equipment. Leaving the product to sit for 20-30 minutes thereafter is a good way to give the product time to work and dissolve existing rust and corrosion before flushing out the system. Use of EcoClean® Biodegradable Scale and Rust Remover should be followed by neutralization with an alkaline cleaner such as those in the VpCI®-41x Series, which also provide flash rust protection.

Don’t Wait—Now Is the Time to Maintain

Waiting to remove scale and rust only makes the problem worse. Routine maintenance with EcoClean® Biodegradable Scale and Rust Remover is an excellent option for those who want to improve flow and heat transfer efficiency while using a biobased product and avoiding more serious system problems down the road. Contact Cortec® to learn more about using this biobased scale and rust remover in your heat exchanger, chiller, or cooling tower!

PRESS RELEASE: Getting the Most Out of Dual SACI and Concrete Sealer Systems

  By

When performing a concrete repair or routine sealer application, is there any benefit to adding a surface applied corrosion inhibitor (SACI) underneath? Will the combination enhance protection or undermine the whole system? Cortec® looks at these issues and suggests how contractors can get the most out of their dual SACI waterproofing system.

dual SACI and concrete sealer systems

Why Use Concrete Waterproofing?

Sealers, waterproofing membranes, and other moisture barrier coatings are a common part of concrete maintenance and repair. Their chief purpose is to block or seal the surface so that moisture, chlorides, and carbonation cannot seep into concrete pores. This slows down the deterioration process and helps the concrete last longer. Common places to find epoxy or urethane coatings, methyl methacrylate sealers, or other waterproofing membranes on concrete are parking ramps and industrial buildings—especially those in the chemical processing industry.

What Are the Benefits of SACIs?

Treating concrete with SACIs before applying a coating, sealer, or traffic membrane adds an additional level of corrosion protection. MCI®-2020 contains the highest corrosion inhibitor concentration among SACIs on the market and is therefore the most efficient choice for this application. Migrating Corrosion Inhibitors in MCI®-2020 penetrate concrete pores and are attracted to metal surfaces to form a molecular layer that actively inhibits the corrosion reaction. This second line of defense is especially important if the physical barrier or coating fails, allowing water and corrosives to seep in and be trapped on the concrete surface. The presence of SACIs in the concrete can help mitigate the corrosion reaction.

How to Ensure Proper Adhesion

While both sealers and SACIs can play a role in concrete protection, there is sometimes a concern for adhesion between layers when applying multiple products to a concrete substrate. If adhesion fails, the effectiveness of the applied system is jeopardized, leaving concrete exposed to water and other contaminants. Fortunately, the solution is as simple as proper application. Waiting 24 hours after applying MCI®-2020 gives more time for the corrosion inhibitors to work their way into the concrete pores, away from the surface. Subsequent rinsing with water removes any residual and leaves behind a clean surface for coating or waterproofing application. Testing according to ASTM D7234 has confirmed the compatibility of several traffic coatings and membranes with MCI®-2020, and in some cases, a water rinse was not needed to maintain adhesion.

Get the Most Out of Your Surface Applied System

Application of water repellents, coatings, and waterproofing membranes will remain a common practice as long as parking garages and other concrete structures remain vulnerable to corrosion. Using MCI® SACIs is a great way to enhance routine maintenance or repairs by fortifying the concrete with Migrating Corrosion Inhibitors. Simple steps such as rinsing the surface prior to waterproofing application helps contractors and building owners get the most out of their dual water-repelling corrosion inhibiting system to extend concrete service life. Contact Cortec® MCI® for more advice on choosing your next concrete surface treatment for best results.
