Algae Farms and Lake Erie Algal Blooms Causes and Solutions

Requirements for Algal Growth Sunlight Water Carbon dioxide Nutrients Nitrogen Phosphorous Potassium

Methods for algae farming Ponds – (raceways) Artificial surface areas Arranged in rows similar to corn crop Shipping containers

Closed Loop Systems (all products utilized) Heat supplied by fossil fuel… …Carbon dioxide from heating system pumped into water for use by algae Oil and biomass extracted from algae Biomass used for production of biogas and food products Materials left (effluent) are rich in nitrogen & phosphorous and used to fertilize new algae Waste water can be used/reused in this process

Toxic Blooms Causes Lake Erie is shallow, water warms quicker Lake Erie is most southern of Great Lakes, warmer environment Agricultural run off-phosphorous & nitrogen Failing sewage treatment incidents during storms Failing septic systems Industrial waste

Solutions Most immediate Reduce agricultural run off Improve technology in water treatment plants remove toxins from drinking water Reduce agricultural run off Improve sewage treatment capacities to… Handle storm volumes Improve/replace septic systems Improve industrial waste treatments
