Closed Loop Wastewater System

Our system plan starts with maceration after flush toilet to 1/8" and smaller particles up front, to be eaten by 1 cubic yard aerobic worm beds, then to be filtered by a cubic yard of biofilter stage 1, then biofilter stage 2. Probably flat Algae panels for nitrogen processing, designed to fit within 4 cubic yards per person in the first prototype, then scaling to higher numbers of people. Outputs would be compost and flushing water. Adding another cubic yard would get us to potable water. Do you think this design is up front workable?
