Ecological Concepts



Any oxidizable material present in a natural waterway or in an industrial wastewater will be oxidized both by biochemical (bacterial) or chemical processes. The result is that the oxygen content of the water will be decreased. Basically, the reaction for biochemical oxidation may be written as:
Oxidizable material + bacteria + nutrient + O2 → CO2 + H2O + oxidized inorganic e.g. NO3- or SO4

Oxygen consumption by reducing chemicals such as sulfides and nitrites is typified as follows:

S-- + 2 O2 → SO4--

NO2- + ½ O2 → NO3-

Biological oxygen demand (BOD) is a measure of the amount of oxygen that is consumed by bacteria during the decomposition of organic matter.  Having a safe BOD level in wastewater is essential to producing quality effluent. If the BOD level is too high then the water could be at risk for further contamination, interfering with the treatment process and affecting the end product.

Chemical Oxygen Demand (COD) measures the amount of oxygen that is consumed by the water in the decomposition and oxidation processes, specifically the decomposition of organic matter and oxidation of inorganic matter, or chemicals.

The so-called 5-day BOD measures the amount of oxygen consumed by biochemical oxidation of waste contaminants in a 5-day period. The total amount of oxygen consumed when the biochemical reaction is allowed to proceed to completion is called the Ultimate BOD. Because the Ultimate BOD is so time consuming, the 5-day BOD has been almost universally adopted as a measure of relative pollution effect.

There are also many different COD tests of which the 4-hour COD is probably the most common.

If effluent with high BOD levels is discharged into a stream or river, it will accelerate bacterial growth in the river and consume the oxygen levels in the river.

Current legislation demands continually lower levels of these parameters in order to preserve the receiving water bodies and their aquatic life. The main focus of wastewater treatment plants is to reduce the BOD in the effluent discharged to natural waters.

Controlling of BOD and COD can be achieved either by employing Microbes or by Chemicals or by Aerators.

The BOD removal efficiency of aerobic biological treatment processes depends on a number of factors including (but not limited to): influent BOD loading, nutrient to biological mass (FM) ratio, temperature, nutrient levels and dissolved oxygen (DO) concentrations.

Aerators consume lot of Power.

Pure oxygen, hydrogen peroxide (H2O2), or ozone (O3) is the normal chemicals employed.

These procedures may also be combined with Ultra Sound reactors, UV irradiation and specific catalysts. This results in the development of hydroxyl radicals.

A single product cannot serve at all temperatures and at different pH.

ECOXYGAIN is a blend of several active components and adjuvant; and designed to work at extreme conditions also.

The more particle-bound COD, the more efficient the removal rate by employing ECOXYGAIN.

If ECOXYGAIN is used before the secondary treatment, the biological process will work more efficiently and consume less energy.

Or if needed, the plant capacity can be increased without any major investments.

A wastewater treatment plant using ECOOXYGAIN to support BOD/COD removal will always be the most compact plant and leave the smallest possible environmental footprint.


IRON BEARING WATERS are often deferrized by oxidizing the ferrous iron with dissolved oxygen and then removing the resulting ferric oxide floc by sedimentation or filtration.

That means oxidation is required before precipitation, settling and/or filtration.


The reaction of Fe(II) with oxygen generally leads directly to ferric oxides or hydroxides. The stoichiometric relationship being

Oxidation of ferrous iron is only one step in the deferrization process. Flocculation and sedimentation (or filtration) certainly may codetermine the over-all iron removal rate in surface waters and in iron removal plants. Many constituents present in natural waters may accelerate or decelerate the oxidation as well as the flocculation reaction. It can be inferred from our experiments, however, that the oxidation reaction may be the controlling factor up to pH values around 7. In the more alkaline pH range, flocculation may be the slowest step. At pH values above 8, diffusion or the oxygen rather than the chemical reaction determines the oxidation rate.

In many natural waters organic matter may stabilize ferric oxide colloids or may increase the Fe(III) solubility by complex formation. Generally, iron removal is very slow under such conditions.


Most organic impurities are known to hasten oxygenation reactions; under these conditions, difficulties in iron removal are apparently due to slow flocculation.

Our ECOOXYGAIN is recommended @ 1 mg/ 1 L. At this level, it can remove up to 12-25 mg/L of combined concentrations of Fe/Mn. 

Mode of action

When in contact with water it will immediately begin to decompose releasing oxygen.

Storage and shelf life:

  • Store in a dry location away from heat and out of direct sunlight in containers fitted with a safety valve or vent. Storage temperature: <104°F (40°C).
  • Store in an area away from acids, bases, metals, metal salts, reducing agents, organic materials or flammable substances.
  • Do not store near or expose to heat sources (ie: steam pipes, radiant heaters, hot hair vents or Welding sparks)
  • Never return unused product to the storage container.
  • Rotate inventories - first in, first out.
