Abstract: A low cost system for treating water, which will be used in an industrial process, is provided. A system of the invention generally includes at least one containing means (8), at least one coordination means (1), at least one chemical application means (4), at least one mobile suction means (5), and at least one filtration means (3). The coordination means (1) can control the necessary processes depending on the system needs (e.g., water quality or purity). The system of the invention purifies the water and eliminates suspended solids without the need of filtering the totality of the water volume, but only filtering a small fraction of up to 200 times less than the flow filtered by a conventional water treatment filtration system.

Abstract: A method and system of providing ultrapure water for semiconductor fabrication operations is provided. The water is treated by utilizing a free radical scavenging system. The free radical scavenging system can utilize actinic radiation with a free radical precursor compound, such as ammonium persulfate. The ultrapure water may be further treated by utilizing ion exchange media and degasification apparatus. A control system can be utilized to regulate a continuously variable intensity of the actinic radiation.

Abstract: The present disclosure relates, according to some embodiments, to systems and methods for processing organic compounds, such as manure or other organic waste. Embodiments may comprise a first containment chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, a sulfide gas treating unit may receive and treat sulfide gases from a first anaerobic chamber and/or a second anaerobic chamber. A water storage unit may receive and store waste water or effluent from a first anaerobic chamber and/or a second anaerobic chamber.
