Like all living organisms, microbial populations contained in waste handling systems that are responsible for the ultimate stabilization, or treatment, of the waste have a
minimum nutrient and oxygen requirement. Frequently the concentration of many of these nutrients and oxygen contained in existing waste systems is insufficient or not
in a usable form for microorganisms In addition to the many required micronutrients, microorganisms also require organic nutrients.
These organic nutrients are sometimes known as "growth factors" and are compounds necessary for organic growth because they become constituents of organic cell
material that cannot be synthesized from other carbon sources. Growth factor requirements differ from one organism to another, but the major ones fall into the following
three classes: amino acids, purines and pyrimidines and vitamins to maintain microbial cell synthesis and growth. The lack of required nutrients is typically the limiting
factor in the treatment or ultimate stabilization of the waste.
Typical conditions of a biomass include an abundant source of organic matter and the symbiotic activity of many different types of micro-organisms that metabolize and
stabilize within the biomass. Some species of bacteria are specialized and their normal growth and development is often inhibited by the lack of readily available
essential nutrients and other growth factors which cannot be synthesized from the organic matter present. These growth factors are amino acids, purines, pyrimidines
and vitamins. Each individual species reacts differently and with different sensitivities to the various growth factors. This means that in a mixed microbial population,
individual species with desirable qualities can be purposefully stimulated while simultaneously suppressing bacteria with negative or undesirable qualities. Judiciously
prepared organic nutrients would furnish the said properties.
The presence or absence of oxygen in the environment is important in the growth of microorganisms. In some cases, the type of metabolism used by a particular
organism may differ according to the concentration of oxygen. Oxygen has limited solubility in water.
Therefore, in still aqueous environments, availability of oxygen may be a limiting factor in the growth of microorganisms. Many cells may utilize oxygen for their
metabolism, and since oxygen cannot easily diffuse back into the solution, the environment becomes oxygen-depleted.
Except a few facultative or anaerobic microbes, all living things, one way or the other, require oxygen to survive. Microbial populations in waste handing systems that are
responsible for the ultimate stabilization, or treatment, of the waste have minimum oxygen requirement. Frequently the concentration of oxygen contained in existing
waste systems is insufficient or not in a usable form for microorganisms to maintain microbial cell synthesis and growth. The lack of required oxygen is typically the
limiting factor in the treatment or ultimate stabilization or the waste. In general, the saturation concentration of oxygen in pure water at 25 degree centigrade is
approximately 8.2mg/L, however, as salinity of water increases, solubility of oxygen is further decreased. For example, at 2.5% salinity, 25 degree centigrade, saturation
oxygen concentration is only 7.2 mg/L. These numbers demonstrate that in a waste water system it becomes more difficult to get oxygen into the water due to the
dissolved solids associated in it. As a result, in such an oxygen-depleted environment, anaerobes dominate the eco-system and start the notorious digestion process
producing very unpleasant odor and noxious by-products into the waste water system.
Another challenge usually encountered is the rate of oxygen dissolution not fast enough to enable an efficient replenishment. In a typical aeration system, the air supply
must be adequate to Satisfy the BOD of the waste. Satisfy the endogenous respiration by the sludge organisms, and Maintain a minimum dissolved oxygen (DO)
concentration of 1 to 2 mg/L throughout the aeration tank.
Conventional means of oxygen introduction into waste water system could be roughly divided into two main streams: passive and active. Passive ones employ the
surface oxygen diffusion principle where oxygen moves into wastewater from atmosphere by natural surface interactions and by contact. In the active format, various
techniques to mechanically or physically force oxygen into the waste water system are designed. Ways are either in the format of the air bubbles to increase the overall
contact area for oxygen, solution or pumping wastewater to flow in a high speed and turbulent manner to increase contact with air.
Nevertheless, the natural limitations of oxygen solubility still hinder efficient delivery of oxygen to the microorganisms in wastewater. For food-to-microorganism ratios
greater than 0.3, the air requirements for the conventional aeration process amount to 500 to 900 cuft/lb for fine bubbles (porous) diffusers.
At lower food-to-microorganism ratios, endogenous respiration nitrification, and prolonged aeration periods increase air use to 1200 to 1800 cuft/lb of BOD
removed. In the Ten State standards, the normal air requirements for all activated-sludge processes, except extended aeration, are 1500 cuft/lb BOD for peak aeration
rank loading. For diffused-air aeration, the amount of air used has commonly ranged from 0.5 to 2.0cuft/gal at different plants. To introduce such an amount of air into the
wastewater sufficiently and in a fast enough rate to ensure effective oxidation of organic waste and to support microbial growth is a very energy consuming task. Simply
using mechanical means, due in part to the low solubility of oxygen in water and to the slow dissolution process, would waste a great deal of energy to drive the
machinery to achieve desirable dissolved oxygen (DO) level.
There has been technology using pure oxygen in place of air for aeration process in certain special applications, aiming to enhance the oxygen dissolution properties.
Nevertheless, such physical approach utilizing a higher oxygen partial pressure results with certain improvement but was not justified by its high cost and still
jeopardized in heavy loading waste water system.
Reviewing the conventional methods of oxygen introduction utilizing mechanical means, knowing their strengths and weaknesses, a novel approach of raising DO level
of the natural water body or waste water system using organic based chemicals was formulated. Such DO increasing to optimize the benign aerobic microbial activities
in the stabilization or treatment of waste.
ABS Oxygen Alleviating Agent is part of the biological waste treatment system additives containing a proprietary blend of organic based chemicals and hydrogen
peroxide. The goal is to stimulate the specific group of microorganisms calledfacultative anaerobe to restore their naturally given functionalities to lower suspended
solids, biochemical oxygendemands, chemical oxygen demand, etc. in the environmentally unfriendly biomass.
The ABS Oxygen Alleviating Agent does not contain bacteria or enzyme, but rather is designed to stimulate the existing bacteria found in biological systems.

| ABS Mobile Sewer Cleaning Process |
Addition of ABS-181 will prevent sewer and leach line constriction, it does this in two ways: 1) it oxidizes microbial slimes that
block leach lines; and 2) it decomposes once permeated into the sewer line system; liberating oxygen, conversion from a
liquid to a gas represents a volume expansion whereby the compacted soil is a airspace restored to the soil structure.
