Method of combining waste water treatment and power generation technologies

A method of producing electricity comprising the steps of:

• delivering waste water effluent to a geothermal steam field;
• injecting said effluent into said field;
• collecting steam and hot water from said field;
• and
• directing said steam and hot water to a lower elevation by force of gravity, through a hydroelectric turbine-generator, extracting energy in the form of electricity.

A method of employing waste water effluent in power generation comprising the steps of:

• delivering waste water effluent to a geothermal steam field, said delivery including at least one stage of pumping said effluent through a piping system;
• injecting said effluent into said field;
• collecting steam from said field;
• extracting energy in the form of electricity from said steam by expansion in a steam turbine-generator system thereby producing condensate, said effluent being utilized as cooling water in said turbine-generator's condensing heat exchanger;
• reinjecting a fraction of said condensate into said geothermal steam field;
• directing a fraction of said concentrate to a lower elevation by force of gravity in a penstock, directing said condensate through a hydroelectric turbine-generator, extracting energy in the form of electricity;
• directing a fraction of said concentrate from said steam turbine-generator to a holding pond;
• and
• treating a fraction of said condensate producing potable water.

A method of employing waste water effluent in power generation comprising the steps of:

• delivering waste water effluent to a geothermal steam field, said delivery being accomplished by three stages of pumping said effluent through a piping system, said pumping of said effluent taking place during off-peak periods of electricity consumption;
• injecting said effluent into said field;
• collecting steam from said field;
• extracting energy in the form of electricity from said steam by expansion in a stem turbine-generator system thereby producing condensate, said effluent being utilized as cooling water in said turbine-generator's condensing heat exchanger;
• reinjecting a fraction of said condensate into said geothermal steam field;
• directing a fraction of said concentrate to a lower elevation by force of gravity in a penstock, directing said condensate through a hydroelectric turbine-generator, extracting energy in the form of electricity, said hydroelectric generation being accomplished during peak periods of electricity consumption;
• directing a fraction of said concentrate from said steam turbine-generator to a holding pond;
• and
• treating a fraction of said condensate producing potable water.

A method of employing waste water effluent in power generation comprising the steps of:

• delivering waste water effluent to a geothermal steam field;
• injecting a fraction of said effluent into said field;
• collecting steam and cooked water from said field;
• extracting energy in the form of electricity from a portion of said steam by expansion in a steam turbine-generator system thereby producing condensate;
• and
• treating fractions of said condensate and said cooked water to produce potable water.
