A water purification system comprises a bioreaction subsystem receiving contaminated input effluent and having a gas-lift anaerobic membrane bioreactor removing urea and organic matter to create a first effluent. A light-treatment subsystem receives the first effluent and exposes the first effluent to UV light to create a second effluent free from microorganisms. A reactor subsystem fluidically connects an ammonia-reducing reactor to the UV output and receives UV-treated second effluent and has a struvite regenerator connected to the ammonia-reducing reactor output, separating ammonia from the second effluent in the ammonia-reducing reactor, and outputting the ammonia. A separation subsystem fluidically connects to the reactor output and receives the second effluent substantially free from ammonia and has a continuous electro-deionization device separating brine/salts from the second effluent to produce potable water. A closed-loop includes an ammonia-converting subsystem and a sequential fertilizer producer.

A method of generating organic fertilizer material may include generating biologically produced sulfuric acid by passing an aqueous solution including sulfur over a material that may include sulfur oxidizing microorganisms. The operations may further include, recirculating the aqueous solution over the material until an amount of biologically produced sulfuric acid in the aqueous solution may reach a predefined threshold. The operations may further include extracting the biologically produced sulfuric acid from the aqueous solution. Further, the operations may include generating the organic fertilizer material using the extracted biologically produced sulfuric acid and an organic feedstock.

A process is disclosed for creating biologically active soil or horticulture media for growing plants, wherein a fibrous carbon source such as coconut coir in a predetermined particulate form is mixed with fertilizers and other biological nutrients, inoculated with a biologically active substance such as worm castings and then aged or cured in an oxygen rich aerobic process. After which additional nutrients can be added to tailor the aged media for a specific sue. Various apparatus with which to conduct the aging process are also described. In a variation of the process used soil or horticulture media is recharged by first composting at a high temperature to remove harmful and unwanted items, its contents are evaluated, nutrients are added, and it is then aged in an aerobic process.
