Phoenix CompostingToilet System 1997/JanDesign features of the Phoenix' 1997, Advanced Composting Systems, all rights reserved.One or two toilets connect to the Phoenixwith 12-inch diameter pipe. The toilets aremolded from vandal resistant polyethyleneand ABS plastic.The accumulated liquid and/or fresh wateris automatically resprayed on top of thecompost pile to maintain moisture andinoculate the pile with compost-friendly micro-organisms. The excess liquid is drained to aleach field, or an evaporation or holding tank.Rotating tines control the downwardmovement of the material in the compost pile.The big Phoenix Model 201 has three tineshafts, each above the other. The Model 200(shown) has two shafts, and the Cabin modelhas one. (For clarity, only one tine shaft isshown in this illustration.)A leakproof joint is accomplished with agasket and interlocking flange. Assemblyrequires only a few bolts and no caulking.A permanent medium provides second-ary liquid treatment beneath the slopedbottom baffle. Air travels over the entiresurface of the liquid to increase evaporationand aerobic conditions.The Phoenix is fabricated from rotationallymolded solid and foamed crosslinked andlinear polyethylene, assuring many years ofservice. The tank is durable, corrosion resistant,leakproof, and continuously insulated.Finished compost is removed easily throughthe lower access door from the entire bottom ofthe Phoenix assuring maximum and uniformretention time.Air enters the Phoenix through a screen inlet.A sealed path for ventilation air, and a largecontact area, increase ventilation efficiency andallow supplemental heating.Continuous air baffles along the tanksides provide aeration of the compost pilewithout interfering with compost movement.Their large surface area allows the insulatedtank to be readily warmed with circulating airfrom a heater or active solar collector.Ventilation is provided by an efficient, 4-watt, direct current fan. The fan housing ismounted directly to the tank for easy mainte-nance. A small power supply or a photovoltaicsystem provides the energy. Flexible 4-inch ductand 4-inch PVC pipe are installed easily.Liquid is separated from the solids by ascreened baffle and resprayed, or drained,from the Phoenix. The drain connection canbe made from either side through an inch-and-a-half flexible hose.Now on the Internet http://www.compostingtoilet.comAdvanced Composting Systems ? 195 Meadows Road ?
