Wastewater and Effluent Recycling

Global Wastewater's proprietary extended aeration systems are applicable for flows of a few hundred gallons to tens of millions of gallons per day. There is NO SLUDGE to dispose, NO ODOR, and our systems require very little maintenance. The Global process is designed around modularization to be able to grow a system efficiently and quickly as needs grow.

Operating the System
Raw sewage enters the unit through the influent line and passes through a bar screen, which keeps out any large solids. A diffuser system introduces air into the aeration chamber. The air bubbles that are generated provide the oxygen necessary to sustain the bacteria and also provide the agitation necessary to reduce solids to small particles.

After a suitable retention time, the solution is displaced from the aeration chamber to the clarifier chamber. There the remaining solids settle to the bottom in the form of activated sludge. The sludge is returned to the aeration chamber to maintain a high active bacteria count. The clear liquid at the top of the clarifier chamber flows into the LS3 wastewater purification system to kill any disease-carrying bacteria that remain. The effluent is then purified into polished quality drinking water.

Explanation of the Wastewater and Recycling System
The first aspect of understanding, regarding the Global Water process, is that it is more environmentally correct and efficient to recycle wastewater than to just try to clean it and hope that the effluent doesn't ruin your land, your beaches, or your lives.

Most wastewater processing now results in "dumping" the effluent flow into the lakes, bays, rivers or right onto the land. The "sludge" from wastewater "drying ponds" is "dumped," left on the land, or processed into a fertilizer (with sometimes questionable ingredients).

The Global process is to totally destroy and eliminate all waste products from the wastewater stream and then recycle the effluent flow back to the quality of drinking water. Then to disperse that final, clean effluent back into the bay, or into reservoirs for reuse, or into useful water sources for maintenance, agriculture or other needs is the only way to preserve a higher quality of life and preserve our land.

Global's proprietary Wastewater Process is what we consider to be the best currently available when analyzing ease in installation, ease in operations, minimal maintenance and resulting effluent (output). The Global process is designed around modularization to be able to grow a system efficiently and quickly as needs grow.

The normal processing time for an extended aeration system is 24 hours to turn out effluent from a high quality wastewater system that can be put back into the ground (after chlorination). Because the Global Recycling-Water System is so effective, we can pull the effluent from the wastewater system in ONLY 12 HOURS. Therefore, the wastewater system needs to be only HALF THE SIZE. For a 1,000,000 gallon per day requirement (1MGPD), you only need to have a 500,000 GPD wastewater system (that will cycle twice per 24 hours)! Then you would need a 1MGPD Global Recycling-Water System to recycle all 1,000,000 GPD.

The cost of both components in this configuration is about the same as just utilizing only the full sized wastewater component.

Understanding the Process
Global Wastewater systems utilize the biological treatment process to clean up sewage. All of the sewage input is food for microorganisms. Raw sewage is consumed by the microorganisms and is used to provide energy for cell activity and material for cell reproduction. These processes are called respiration and synthesis.

For years municipal sewage treatment plants use biological in one form or other. The process of biological treatment is proven and most economical.

The prime factor of biological treatment processes is that the microorganisms (mostly bacteria) are able to easily remove organic wastes from a liquid that would otherwise be very difficult and expensive to remove by other means.

There are two types of bacteria used for biological sewage treatment systems and they both are naturally contained in the sewage.

One type is anaerobic bacteria. This type does not require oxygen for their metabolism. They will consume the organic waste material in sewage, but release methane and hydrogen sulfide gas as a by-product. Both of these gases are explosive, and the hydrogen sulfide produces the offensive odor associated with this process. In addition to become efficient, anaerobic processes require some form of heating. These reasons have precluded the use of anaerobic bacteria for package type sewage treatment units.

The second type of bacteria is aerobic. They must have oxygen for their respiration and synthesis process. They consume the organic waste material in sewage and release carbon dioxide and water vapor as by-products. This does not result in any odor or explosive hazard. No special heating requirements are needed, if the sewage treatment units are located where hard freezes do not occur. The aerobic process is also faster than the anaerobic process, with regard to waste reduction reaction rates.

If the sewage is permitted to become stale and subsequently to become septic, its odor becomes pronounced, it turns black, the solids disintegrate and decompose, the dissolved oxygen is used up, and the formation of hydrogen sulfide starts.

Both anaerobic and aerobic treatment systems are biological. That is, they depend on bacteria to consume and eliminate the organic waste material in sewage. An aerobic (air required) sewage treatment process, if the air supply is cut off. It will be a gradual change, and the odor will increase as the process becomes more anaerobic. However, the process will revert back to an aerobic process once the air supply is restored. It can take twelve to thirty-six hours for an aerobic system to become anaerobic, depending on unit size of loading.

Global Wastewater's proprietary sewage treatment unit utilizes a type of aerobic biological treatment process called an "extended aeration activated sludge" process.

The microorganism or bacterial cell mass that is generated by cell reproduction is separated from the liquid being treated prior to discharge, collected, and mixed with incoming sewage. This increases the rate of removal of the organic waste coming into the system, because the waste comes in direct contact with a hungry a relatively dense population of bacteria almost immediately. This arrangement is called an "activated sludge" process.

Global's extended aeration treatment process creates a super-charged environment for the bacteria to generate more digestion in less time, enabling the recycling system to initialize its process much quicker. This arrangement keeps the ratio of bacteria population (sludge) to the available food supply (sewage) essentially constant. The bacteria cells are continuously multiplying, and the cell population exceeds the food supply available for feeding the excess population. These cells starve to death and become food for the survivors. The result of this process is to minimize bacterial cell sludge accumulation in the sewage treatment unit.

Global Water's Recycling Process
Global's Wastewater System has an enhanced efficiency with a Global Recycling-Water System. The Global Recycling-Water System will receive the effluent from the wastewater flow after only (12) hours. It will then recycle all suspended solids back to the wastewater unit.

The remaining effluent will be processed through Global's water purification process just as any other contaminated water source. Any remaining parasites and hazardous chemicals will be removed, and then all effluent will be treated with ultra-violet lamps to kill all bacteria (e-coli) and viruses.

The output of the Recycling-water system will be totally recyclable for re-entering the environment (ground or water disposal), being used for non-food or non-drinking purposes (toilets, washing equipment, etc.), or actually being potable for re-use.

Marine and Land-based Systems
Global Wastewater manufactures two distinct styles of equipment: One geared for the Marine market (boats, barges and ships) and one for land based environments.

Sewage treatment systems that do not employ the extended aeration treatment concept will require continuous drain off and disposal of sludge, because bacteria are not kept away from a food supply long enough to keep the bacteria population from increasing. As a result, the bacteria population will continue to increase to a point where the sludge density becomes so great, that sludge is discharged from the sewage treatment unit.
