Wastebuster


The WasteBuster combines our proven process with traditional oil/water separation and an effective waste treatment technology. This combination provides for continuous oily water degradation, separation and filtration that results in an acceptable discharge for recycling or release to the sewer.

Our process of degradation consists of microbes, micro-nutrients and liquid catalyst. The process has been successful in bioremediation of open ocean tanker spills, pipeline spills, lagoons, oil field producing pits, soil (land farming and in-situ) and many other applications.

The WasteBuster may also be utilized for batch treatment of oily waste and for ground water pump and treat applications.

Operating Sequence:

The waste stream in inoculated with microorganisms and catalyst. This inoculation generally takes place in the collecting sump or tank. Degradation of the contamination begins at this point.

The waste stream is transferred to the reactor tank, where diffused air is introduced to enhance the degradation.

After reaching the capacity of the reactor tank, the waste stream is transferred to the coalescer separator. The coalescer separates any remaining hydrocarbons and returns them to the reactor tank for further degradation.

The water continues this process between the bioreactor tank and coalescer separator until hydrocarbons have been significantly reduced.

The resulting clean stream empties into the filler tank where the water passes through a series of three filtering compartments.

Clean water is then transferred through a sand filter for removal of suspended solids and finally through a carbon tower for final polishing.

At this point, the water is ready for discharge into the sewer system, or may be reused as wash down water.

The continuous degradation, separation and filtering process is provided at a flow rates of 5, 10, 20, or 30 gallons, per minute, dependent upon the size of the unit in service.

The entire system is mounted on a single angle iron skid with opening of fork lift or lifting lugs to facilitate on-site handling. The system is operated on 220 volt single phase circuit and explosion proof motors are available upon request.

Major Components are:

1. An aerated mixing/reaction tank.

Input to the system is through this tank. Adequate holding time is provided for bio-destruction of the hydrocarbons in the waste stream. Air is introduced to the tank for mixing and as a source of oxygen for the bio-destruction process. At start-up, the system is inoculated with a proprietary blend of bio-cultures. The bio-culture will be added weekly so that optimum strengths will be maintained. The bicultural is a selected group of naturally occurring oil eating microorganisms that in dry powder form have a concentration of 10 (12) cells per gram.

In addition, any oxygen transfer enhancing reagent is added weekly to the system. The oxygen transfer enhancing reagent is a unique proprietary biocatalyst and is applied to increase the activity and growth of micro-organisms.

2. An oil/water separator specifically designed to function in the oily waste water destruction system.
Clear water output from the system flows from the oil/water separator. The separator provides a quiescent zone for settling of solids and coalescing of emulsified oil in the waste stream prior to discharge from the system. The waste stream is mixed and aerated in the reaction tank and brought into contact with the bio-culture and oxygen transfer reagent. The mixed waste stream is pumped (continuous operation) to the quiescent zone in the separation tank. The separated hydrocarbon is returned to the reaction tank by gravity flow. Separated water is pumped through filter elements to the clean water storage tank.

3. Clean water storage and sand filter.
The clean water from the oil/water separator is transferred by pump to a clean water tank for re- use. The clean water is circulated through a sand filter and carbon tower on a continuous basis. As needed the water is then pumped under pressure to the cleaning operations.

Attention by operating personnel is minimal. Various options are available as required.

Input/Output Control
With zero input to the system, the valve remains open and liquids are recirculated as previously notes, With input to the system, the liquid level is elevated to shut-off flow to the reaction chamber. Liquids are forced through the coalescer pack and over the output weir as a clear water discharge.

Setting Recirculation Rate
The recirculation pump is regulated by an in-line ball valve. Pump rate is to be the maximum with no overflow at the output weir and zero input to the system.

Setting Aeration Rate
Control can be by a pressure regulator or manually. Flow rate is set so as to provide complete mining in the contact chamber.

Bioculture/Reagent (Inoculation at start-up)
An initial supply of both bicultural and reagent will be furnished with the equipment. These should be on hand at start up.

The initial charge of bicultural to the system includes treatment of sump and bioreactor. Additional bicultural and reagent will be furnished as required.

Re-Cycle
Louisiana Bio-Environmental/Biotek has approximately eight (80) WasteBusters in use throughout the United States as water recyclers. The systems continually treat the waste streams providing recycled water of sufficient quality to allow repeated use. The only waste product generated is a small inert residue.
