The algae system is not a substitute for a wastewater treatment plant. Rather, it replaces

the typical equipment used in the biological process of a conventional plant. The algaeplant system provides convention biological wastewater ll as advancednutrient removal utilizing algae. The algae also serve to supply the oxygen required bythe bacteria and likewise the bacteria supply the carbon dioxide required by the algae.Because algae uptake vast quantities of carbon dioxide, the algae system provides acarbon negative wastewater treatment process.

In conventional wastewater treatment facilities the ma ids managementis to minimize or eliminate sludge. Sludge disposal is a costly part of operationconventional plants because conventional designs use large amounts of energy to reduce

sludge to a minimum, and then more energy to dispose of the leftovers.

In an algae wastewater treatment facility the main objective of sludge management is tomaximize algae biomass production. The algae and sludge mixture created by algae isbtu-rich biomass that can be refined to create steam, heat, electricity, or biofuels.Depending on site conditions, the energy generated by the system either eliminates of significantly reduces the facilitys need to purchase energy. In fact, there is excellentpotential for creating excess energy that could be sold to offset the cost of operations.

With algae there is no leftover sludge that has to be disposed of which eliminates thecost of sludge di sposal and the contamination of food crops with pharmaceuticals and

pathogens. Lastly, the EPA has identified conventional wastewater treatment plants asmajor contributor to greenhouse gases. The algae plant, however, is actually carbonnegative because algae use more C02 to grow than the algae wastewater plant emits.

Algae can be used to capture C02 emissions from coal plants, ethanol plants, concreteplants, and any other industry that has C02 emissions. The algae production process willreduce greenhouse gases and allow the user to obtain valuable tax credits and to sell or

utilize carbon credits. If energy is also produced the project may be eligible for

Algae can be utilized for production of many types of biofuels including: BioDiesel,Ethanol, Bio -Butanol, Gasoline, Jet Fuel and others. Algae are found in many types of environments throughout the earth and are capable of producing vastly more biofuel peracre than terrestrial plants. Incentives from the federal government and many stategovernments can significantly offset biofuels production and facilities cost.

Algae require very basic elements to grow: C02, nutrients, water, and sunlight. The keyto our algae system is it maximizes algae production by processing th ese elementsefficiently. The systems three -dimensional shape provides a much greater surface areathan a two dimensional pond our raceway.

The most significant advantage of the system is the ease in which algae is harvested.Suspended algae are captured as they flow through the system. Attached algae arenaturally sheared off the system when they reach a certain mass. This combination of processes allows automatic harvesting of the algae downstream of the algae system.

Sewage can be treated with algae, reducing the need for greater amounts of toxicchemicals than are already used.Algae can be used to capture fertilizers in runoff from farms. When subsequentlyharvested, the enriched algae itself can be used as fertilizer.Algae Bioreactors are used by some power plants to reduce CO 2
