Treating waste streams with organic content

A system for remediating an aqueous waste and a carbon-containing waste, the system comprising:

• a screening unit comprising a carbon-containing aqueous waste inlet, a screened solids outlet, and a liquid outlet;
• a pH adjustment unit comprising an inlet fluidly coupled to the liquid outlet of the screening unit, the pH and flocculating agent adjustment unit suitable for automatically adjusting a pH of an aqueous waste stream;
• an electrocoagulation unit comprising an inlet fluidly coupled to the outlet of the pH adjustment unit and an outlet;
• a storage unit comprising an inlet fluidly coupled to the outlet of the electrocoagulation unit and an outlet, the storage unit suitable for separating floc from an aqueous waste;
• a physical separation unit comprising an inlet fluidly coupled to the outlet of the electrocoagulation unit, the physical separation comprising a centrifuge capable of separating fluid into a heavy fraction and a light fraction, the physical separation unit comprising a heavy fraction outlet and a light fraction outlet;
• a purification unit comprising an inlet fluidly coupled to the light fraction outlet of the physical separation unit, the purification unit comprising at least one of a vapor compression distillation unit or a membrane filter, the purification unit capable of converting at least a portion of the light fraction into water of a selected purity;
• a mixer unit comprising at least one inlet and a mixture outlet, the at least one inlet fluidly coupled to the heavy fraction outlet of the physical separation unit, the at least one inlet coupled to a source of the carbon-containing waste, and the at least one inlet coupled to a source of at least one of kenaf, kenaf bast, or kenaf core, the mixer unit comprising a continuous mixer including a heater, wherein the continuous mixer is a paddle mixer, a ribbon mixer, or a combination paddle-ribbon mixer;
• a briquetter comprising an inlet coupled to the mixture outlet of the mixer unit and a briquette outlet, the briquetter capable of compressing the output of the mixer unit into briquettes;
• a gasification unit comprising an inlet coupled to the briquette outlet of the briquetter, the gasification unit further comprising a syngas outlet;
• and
• a generator comprising an inlet fluidly coupled to the syngas outlet of the gasification unit and an electrical outlet, the generator comprising an internal combustion engine capable of running on at least syngas.
