Abstract:
1. A chemical/biological wastewater treatment method for saline wastewater with dissolved and un-dissolved solids comprising: a. separating the solids in the wastewater influent by passing it through at least one porous drain bag in communication with wastewater influent, the drain bag having a mesh sized to collect and separate suspended solids from filtered wastewater with suspended particles of a size not plugging up a sulfurous acid generator for subsequent acidification, b. collecting the filtered wastewater passing through the drain bag; the drain bag and container, when filled with solids, adapted to be hauled away and the filled drain bag land filled, burned, or gasified, c. passing the filtered wastewater through a sulfurous acid generator, injecting SO d. holding the filtered and acidified wastewater influent within a structure to capture any excess SO f. adjusting the pH of the conditioned wastewater with hydrated or anhydrous lime to reduce the biocidal properties of the free SO g. filtering the pH conditioned wastewater further to remove suspended solids and precipitates to provide a filtered conditioned wastewater of a particle size and concentration level required by end user effluent requirements producing a high BOD dissolved solids and ammonia nutrient liquid solution; g. disposing of the separated solids by land filling, burning, or gasification or composting, and h. passing the nutrient liquid solution through an environmental biological system for consuming the nutrients by land applying it for propagation of biosynthetic fuels.
