BOCs are unique and proprietary bio-organic catalytic compositions that have shown the ability to optimize the performance of the wastewater systems beyond the capabilities of the current infrastructures or chemical agents.  They are directly applicable to solving the critical processing improvements necessary in meeting increased regulatory standards in treating discharges.  BOCs are immediately deployable with simple installations, provide broad overall system improvements, and are extremely inexpensive in contrast to expansion of facilities.

BOC has the ability to exclusively meet the key performance objectives now faced by facilities management, such as nitrogen discharge reduction, increased carrying capacity, FOG treatment, sludge reduction, higher aeration capability, reduction of mineralization build-up, reduction of hazardous gases, and reduction of total discharges.

BOCs work complementary with, and enhance, traditional oxidizing agents, which are already widely used throughout its markets, but are limited in meeting the new advanced levels of regulatory compliance, unable to improve bioprocessing systems, and present health hazards to workers.  BOCs complement and enhance bio-augmentation agents, which while of limited value to most water, wastewater and cleaning applications, are potentially very attractive to accelerating hydrocarbon remediation applications.

The patented BOCs increase dissolved oxygen and reduce the amount of energy required for biological and chemical reactions to occur.  BOCs self-organize and create heavy microbubbles having extremely high oxygen transfer characteristics.  No other catalytic agent can increase dissolved oxygen, or has the wide applicability to treat so many areas of organic contamination.  In aerobic and anaerobic biological processing systems, BOCs increase processing speeds and improve the operating costs associated with meeting the desired processing objectives.

BOCs formulations are a unique physical chemistry, and cannot be categorized as bacteria, enzymes, polymers, or chemicals.  However, they are complementary to all of these agents, and enhance both the processing rates of biological systems and accelerate oxidation rates of oxidizing chemical agents.  Derived from plants and minerals, they are comprised of a fermentation supernatant enhanced synergistically by a non-ionic surfactant to create a functionalized surfactant, protected under BOCs patented proprietary composition formulations.

BOCs formulations work by creating a nearly instantaneous catalytic breakdown of organic molecules, making them more readily digestible by indigenous biology and more rapidly oxidized by chemical agents.  Rather than attempting to break down specific organic elements, as an enzyme would do, a cascading action is created, accelerating biological degradation throughout the spectrum of contaminants.  The increased oxygen availability, higher dissolved oxygen levels, and enhancement in the solubility of cellular material, lead to significantly faster molecular interactions and creates an immediate catalyzing effect on contaminants.

This unique ability of BOCs to rapidly break down organic contaminants, also leads to a whole new class of cleaning and remediation agents, where contaminants are not only removed, they are also degraded into their fundamental elements. This feature creates an entirely new level of cleaning performance never previously possible, as there are no toxic byproducts produced by the cleaning agents, and no remaining organic food sources for future growth of pathogens.  Additionally, the ability of BOCs to degrade biofilms and their organic binders leads to tremendous utility in water purification and distribution systems, and in industrial and institutional cleaning where decontamination is important.

BOCs have undergone extensive and independent testing, showing the highest safety for human, animal, and marine life. BOCs are non-toxic, non-caustic, non-corrosive, non-irritating, hypoallergenic, bacteria-free and biodegradable. This safety profile provides significant competitive advantages against traditional chemicals, including biological agents, due to their unsurpassed handling ease and safety for workers. This is synergistic to the economically compelling benefits BOCs bring to clients in  meeting their tougher governmental discharge standards, by enhancing the biological treatment and purification of their waste streams which must be made prior to their discharge into our public waterways and municipal systems.

BOCs cannot be categorized as bacteria, enzymes, polymers, or as a traditional chemical, rather, the Company has created its own unique product category within the water treatment and cleaning industry. BOCs are comprised of a fermentation supernatant, derived from plants and minerals, which is blended synergistically in combination with a non-ionic surfactant to create a broad spectrum bio-organic catalyst. Unlike conventional surfactants, which can limit oxygen transfer, BOCs self-organize and create heavy microbubbles having very high oxygen transfer characteristics. More available oxygen enables aerobic reactions that will speed up the natural degradation process, while improved gas transfer rates improve both the conversion of insoluble organic waste components to carbon, and enhance maximum utilization of molecular oxygen.

BOCs provide economically compelling benefits to environmental professionals, bringing practical and cost saving advancements to wastewater treatment, water clarification, industrial and commercial cleaning; and have also shown great promise in agriculture, biofilm eradication, and hydrocarbon remediation applications.

Mechanisms of Action:

Catalyzation:  Reduces the amount of energy required for biological or chemical reactions to occur, then participates repeatedly in these reactions while reducing the time and rate required for turnover (accelerates nature’s degradation process 100-fold faster)

Solubilization:  Solubilizes the cellular structure of organic waste, thereby increasing gas transfer rates, and making it easier for naturally occurring bacteria to digest organic substances and oxidizing agents to work.

Oxygenation:  Seeds formation of microbubbles that act as a platform for biological and chemical reactions to occur, and creates a stable, time-delivered system to disperse oxygen throughout the solution thereby increasing the availability of oxygen beyond Henry’s Law (more available oxygen enables aerobic reactions that will speed up the natural degradation process).

Competitive Advantages:

The superior performance and broad applicability of BOCs over traditional chemical agents, or other biologically derived platforms, provides profound competitive advantages in the current marketplace.  BOC’s patented bio-organic catalysts have the ability to exclusively meet the key performance objectives now faced by facilities management, such as nitrogen discharge reduction, increased carrying capacity, FOG treatment, sludge reduction, higher aeration capability, reduction of mineralization build-up, and reduction of total discharges.

BOCs work complementary with, and enhance, traditional oxidizing agents (chemicals, ozone), which are already widely used throughout its markets, but are limited in meeting the new advanced levels of regulatory compliance, unable to improve bioprocessing systems, and present health hazards to workers.  BOCs complement and enhance bio-augmentation agents (bacteria, enzymes), which while of limited value to most water, wastewater and cleaning applications, are potentially very attractive to accelerating hydrocarbon remediation applications.

Convenience and Versatility in Multiple Applications: The integrated nature of the products, combining multiple catabolic process elements, provides extraordinary versatility in application.  While the actual process mechanism is founded on complex biochemical interactions, the methods for use are quite simple and do not represent a barrier to product acceptance.

Significant Performance: BOC’s products offer customers a means to achieve superior performance objectives, often improving the fundamental economics of the applicable process.

Efficacy: BOC’s products have independently demonstrated broad and significant efficacy in process and application enhancement.  In the wastewater industry, BOC can reduce energy costs up to 40% and sludge disposal/ treatment costs up to 30%, eliminate odors and FOG clogging in lift stations, and help facilities reach regulatory discharge requirements.

Non-Toxicity: BOCs are non-toxic, non-caustic, non-corrosive, non-irritating, hypoallergenic, bacteria-free and biodegradable.  The environmentally friendly features of the products substantially reduce exposure and liability to the user, its workers and the environment, and don’t trigger costly OSHA or hazardous material handling requirements.

Fast Results: BOC’s dramatic improvements are achieved very quickly. In wastewater treatment facilities, the early results of FOG elimination and energy reduction are seen within a few days.  Customer satisfaction is a major benefit to market entry and client retention.

Shifting The Nature of Biological Treatment:  BOC has successfully demonstrated the ability to change the fundamental nature of traditional wastewater treatment systems, both in performance enhancement within the treatment system, and in the passive treatment upstream in the collection system.  The biological mechanisms in both elements of the treatment system are beneficially and fundamentally changed, thus reducing major organic contaminant loads from the waste stream.  This results in dramatic improvements in reduction of collection system corrosion of concrete, steel, and aluminum surfaces from H2S gases, loading and throughput at the plant, and reduced energy costs, sludge disposal costs, maintenance and downtime.

Displacing Capital Expenditures: BOC can immediately increase the efficacy and efficiency of wastewater treatment systems, enabling capacity expansion to be deferred for years.  The avoidance of capital costs, coupled with lowered operating costs, has the potential to significantly restructure water treatment project economics in favor of bio-organic catalysts.

Frequently Asked Questions

1.  When are BOCs useful?

BOCs improves environmental waste treatment in a number of critical maintenance and processing areas.  Key attributes that make BOCs  uniquely attractive are its ability to elevate the level of dissolved oxygen (DO) in solution, regardless of aeration technique; ability to solubilize the molecular structure of organic wastes, including the insoluble fats, oils, and grease (FOGs) components, eliminating chronic and dangerous volatile organic compounds (VOCs), such as ammonia and H2S gases, and the ability to enhance biological nitrogen removal (BNR) systems.

Sewers:  Maintaining aerobic environments within collection systems is essential to avoid chronic service problems and dangerous conditions due to hazardous gases, which are also the source of most public complaints.  Eliminating slime layers and FOG clogging are excellent maintenance applications for BOCs.  They can also be used to increase dissolved oxygen levels within both gravity and forced mains, as well as other aerobically compromised parts of the system.

Aeration Systems:  BOCs has been shown to make a substantial improvement in aeration systems through raising dissolved oxygen levels, increasing gas transfer rates, and improving bioprocesses.  Improving aeration system performance can lower energy requirements (up to 30%), along with acting as a method for maintaining higher dissolved oxygen (DO) levels during heavier loading periods, which provides operators with a means to better manage optimum microbiological activities.

Sludge Processing:  Processing of biosolids can be substantially improved with addition of BOCs.  Sludge volumes have been significantly reduced (up to 40%) while methane production quantities were maintained in full-scale applications.  Subsequent treatment and handling of biosolids can be improved due to reduction in odor and better bioprocessing of the bacterial components.

2.  How are BOCs Applied?

BOCs are highly concentrated, completely non-toxic liquid formulation, which are either injected directly into wastewater streams or deployed through spray or fogging systems. It is complimentary to virtually all microbiological systems and chemical purification processes and contributes to the enhancement of these operations. Able to work in conjunction with oxidizing agents, BOCs can substantially reduce the amount of oxidizing agents needed to perform purification requirements, and aid in improving removal of biofilms, which is critical to eliminating pathogen growth and the fouling of filters and membranes.

Delivery Systems:

Metering Pumps: Generally, it is recommended injection of BOCs, with a metering pump, directly into the wastewater stream. Dosage rates are based both upon the flow volumes and organic contaminate (BOD) loading level. For elimination of FOG clogging, BOCs can be injected into sewers at wet wells or other access points.

Injection System: Reduction of ammonia VOCs or wastewater discharges can be substantially improved through injection of BOC into waste stream or sludge transport system.

Air Diffusion Systems: To enhance aeration processing, injection of BOC is made directly into an air diffusion system, at a dosage rate calculated by the flow rate or rate required to meet ongoing performance levels. Increased dissolved oxygen levels have been known to be possible through increasing the dosage rates of BOCs.

3.  Where are BOCs economically viable?

Municipal wastewater operators are faced with multiple challenges, juxtaposed between regulatory compliance, adequate carrying capacities and operating costs.  Each of these areas can be favorably impacted by the use of BOCs.  The cost/benefit correlation of using BOCs versus other alternatives can be quite compelling.

Regulatory Compliance:  Increased regulatory discharge levels require operators to evaluate the most cost effective approach to achieving maximum reduction in discharges.  BOCs help by addressing bioprocessing optimization of existing facilities and therefore are exceptionally cost effective.

System Capacity:  Total bioprocessing loading can be improved through use of BOCs in certain key areas.  Sewer systems can be both alleviated of chronic FOG congestion and deployed as “pretreatment” components where higher aerobic microbiological conditions are created to reduce the total organic load to plant.

Operating Costs:  Numerous elements of system costs can be lowered through use of BOCs.  Studies show that aeration requirements, along with biosolids processing costs, can be reduced by one third.  Many chronic maintenance procedures can be eliminated and personnel deployment savings, along with the worker health risks and public complaints, which are tied to these problems.

4. Can Bio-Organic Catalysts Help in Nitrogen Removal?

The potential of using BOCs to improve nitrification processes is promising due to the oxygen demand required for oxidation of ammonia to nitrate.  Ammonia oxidizing bacteria (Nitrosomonas) obtain their energy by oxidizing ammonia nitrogen to nitrite nitrogen and the nitrite oxidizing bacteria (Nitrobacter) by oxidizing nitrite to nitrate nitrogen.

The oxygen demand for complete nitrification is high as nitrifiers are aerobic and adequate dissolved oxygen levels must be maintained to sustain nitrification.  BOCs has been shown to increase dissolved oxygen levels and lowering the transition of energy required for a catalytic reaction to occur.

The Company has also conducted test programs on the addition of a BOC prior to sludge dewatering for ammonia reduction.  These studies showed :

Reduction of Ammonia concentrations: In the filtrate was reduced 45% to 66%  from its untreated level after a contact time with the BOC of between  2 and 3 minutes.

Ammonia odor reduction: The filter press operator stated that during the trial, the odor from the filter press was significantly reduced (75%).
