Electricity, Water, and Food from Sewage and Sunshine
Richard W. King
The City of San Diego, California, U.S.A. with a regional metropolitan area population of 2.5 million, which is expected to double by the turn of the centuiy, looks to recycling raw sewage as an exploratory model to help meet future water needs as traditional water resources diminish.
The City is studying aquaculture sewage treatment, augmented by ultra filtration, reverse osmosis, and carbon adsorption treatment. A pilot plant with a capacity for 25,000 GPD (94,000 l/d)∗ to 50,000 GPD (188,000 l/d) is operational and a 1.0 MGD (3.8 Ml/d) prototype is under construction, making this the largest system of its kind in the world.
By-products of the aquaculture program, also under investigation, include fuel, animal fodder, agricultural soil “composi”, and commercial fishery potential.
The initial results are highly promising, indicating that the process may be cost effective, energy self-sufficient, except for the reverse osmosis process, and offers an innovative technological breakthrough augmenting conventional sewage treatment, traditional water supplies, and common sources of food, feed and energy.
I would suggest, before you attempt to criticize people on their documentation of the topics you post, while positing yourself as an expert, perhaps you should restrict yourself to topics you actually have comprehension of, or at least make the effort to learn whereof you speak...
