ABSTRACT:
A simple, rapid, efficient and inexpensive process for on-site recycling of wastewater with minimal odor wherein the solid wastes generated by the water treatment process are dewatering on-site by solar energy to water content levels. below those required for disposal. All operations, including solar dewatering, are accomplished in a compact unit which may be mobile. The solar dewatering unit includes a drying pan over which a solar collector window arrangement is disposed.
In the process, wastewater, a water purifying composition and an oxidizing agent are additively mixed together in a first reactor settling tank and the resulting composition is neutralized to a pH of between 7.5-9.4. The added water purifying composition is then allowed to precipitate wherein it binds to and precipitates heavy metals as well as other impurities. The precipitated purifying composition forms a non-hazardous sludge at the bottom of the tank. The resulting supernatant is pumped through a filter to yield recycled wastewater suitable for disposal or reuse. The remaining sludge is pumped to a third tank where it is accumulated and thickened. Once a sufficient amount of sludge is accumulated, the sludge is pumped to a solar dewatering unit where the sludge is dried to a water content level below 50% water which is suitable for landfill disposal.
