Recycle Wastewater Using Algae
This petition is to leverage existing sewage treatment plants by using algae to purify their secondary effluent to where tertiary treatment is practical for fully recycling the water, the algae pressed for biofuels and other attributes, the pressed cakes an agricultural resource needing focus, this as policy as a nation. we need an independent way to gain a biofuel for our transportation that's sustainable, algae grown from wastewater are a human created renewable resource,
Why is this important?
Cities use sewage treatment plants to deal with it, secondary effluent, solids removed is great algae food that's why at the North Lake Tahoe plant they've fully recycled wastewater to prevent algae blooms.
But that's expensive, flocking chemicals are used to pull the fertilizer out of the water, so if you use algae instead they take longer but do a better job making a final treatment relatively cheap to fully recycle the water.
Then, if you harvest that algae it's worth about 2-gallons of biodiesel per person on the system per day, so each of us on a treatment plant system is worth about 2-gallons of a biofuel per day.
The USA burns through about 474-million gallons a day of all types of transportation fuels with 300-million people that's 1.58-gallons per person per day to show the potential volume of purifying wastewater with algae.
For cities they have to watch for toxins and such but if not there the pressed cakes of algae are proving to be good fertilizer for certain crops, early tests in Egypt show a huge 25% jump in wheat yields an example.
So, this establishes from existing local infrastructure a high-volume source of a biofuel, recycles the water and produces a high-volume fertilizer.
An example is Phoenix, AZ, and nearby superbowl Glendale each produce 10-million gallons a day, 41.5-million pounds of fertilizer the algae must consume and doing that they consume CO2 and give off O2 to grow, then worth some 3-million gallons a day of biodiesel each city.
However, the key issue is recycling the water, not making the fuel which is simple, recycling the water means keeping up with millions of gallons a day in volume, a more difficult task.
