TREATMENT OF OIL SPILL WASTE AROMATIC AND LIGHT ALIPHATICS HYDROCARBONS  

Bac-ZymeTM HC is a product composed of specially selected and acclimated bacterial strains that are designed to help degrade an assortment of compounds often found in the discharge waters of refineries, petrochemical plants, and pesticide manufacturers.  Many aliphatic and aromatic chemical compounds found in these discharge waters are included in a “priority pollutant”. These toxic compounds add a new dimension to the problems encountered with conventional biological waste treatment. Because of the toxicity of the wastes, longer acclimation periods are often necessary for suitable efficiency levels to be reached by biological wastewater treatment plants.  Sudden influx of certain of these compounds may result in a toxic shock loading of the biological system, reduction in active biomass, and less efficient treatment of the wastewater stream.

Many chemical manufacturing plants operate various processes on alternating times and schedules. This type of scheduling results in intermittent and non-uniform introduction of different types of compounds into a waste treatment system and can result in poor acclimation levels of the biological microflora.  Because of the non continuous nature of the flow and the types of chemicals entering the system, the indigenous microflora have a difficult time adapting to the changing nature of the carbonaceous waste. Bac-ZymeTM HC can help by supplementing natural microflora with biomass that is pre-acclimated and adapted to biooxidation of toxic, resistant and other recalcitrant carbonaceous compounds resulting in greater  treatment reliability and removal efficiency.

The targeted wastes for this product are generally in the aromatic (cyclic) hydrocarbons and low to moderate molecular weight alkane categories. Included in these types of compounds would be phenol and biphenols (including nitrated and halogenated compounds), benzene, toluene, xylenols, light machine oils, lubricating oils, octane and gasoline, and some linear alcohols.

No products have been shown to be more resistant to heavy metal content than the Bac-ZymeTM HC which can grow on petrochemical compounds, and their concurrent degradation goes on even when 100 mg/l (and sometimes more) cadmium, arsenic, copper, iron, lead, tin, zinc, cobalt, selenium, and silver are present.

Oftentimes, wastewater or soils in the areas of spills or routine hydrocarbon contamination must be supplemented with nitrogen, potassium, and phosphorus to allow the complete breakdown of the hydrocarbon. 

Bac-ZymeTM HC can be the answer to sluggish removal of recalcitrant aromatic and light aliphatic hydrocarbons from waste treatment streams and spills areas.

Recommended Application Rate:

For oil spill remediation and petroleum hydrocarbon contamination treatment, the recommended dosage is 100-200 ppm of Bac-Zyme HC depending on the severity of oil contamination and environmental conditions.  

For optimal biodegradation performance, nutrient supplements with nitrogen (N), phosphorus (P), and potassium (K) may be recommended to enhance microbial activity and accelerate hydrocarbon degradation.

To further enhance hydrocarbon biodegradation, the use of biodegradable surfactants or biosurfactants may be recommended to improve the dispersion and bioavailability of hydrophobic oil contaminants. This allows microbial cells to access and degrade hydrocarbons more efficiently. 

For environmental applications, alkly polyglucoside (APG)-based surfactants or biosurfactants such as rhamnolipids or sophowrolipids are often preferred die to their excellent biodegradability and environmentally friendly profile. These surfactants help reduce surface and interfacial tension, enhance emulsification of hydrocarbons, and increase the availability of oil contaminants for microbial degradation, thereby improving the efficiency of bioremediation processes in petroleum-contaminanted environments.
