Abstract: Embodiments described herein are directed to methods and systems for treating wastewater or storm water using vermifiltration. The wastewater can come from various sources, such as agricultural sources, municipal and industrial sources, wineries, the dairy industry, and many others. The systems can include vermicomposting beds that are capable of removing high amounts of contaminants, pollutants, and/or toxic substances from wastewater. The wastewater may be applied to vermicomposting beds, for example, by an irrigation system. The irrigation system may provide, for example, improved bed coverage and more even saturation. The vermicomposting beds can remove various harmful substances from the wastewater, such as petroleum products; industrial chemicals; heavy metals (e.g., lead, mercury, cadmium, arsenic); pesticides (e.g., atrazine, chlorpyrifos); and organic compounds (e.g., phenols, polycyclic aromatic hydrocarbons (“PAHs”), polychlorinated biphenyls (“PCBs”)).

Abstract: The invention provides a hand-held electronic device for injecting an agent into a tree with continuous pressure sensing technology for real-time measurements of the pressure within the tree. The pressure measurement information is conveyed to an onboard central processing unit for data collection, analysis and optimization of the speed of injecting the agent into the tree. By continually monitoring the pressure and injection power, the injection pressure can be modified to adapt to back pressure fluctuations. In one embodiment of the invention the agent is injected into the tree under a preprogrammed pressure profile. In another embodiment of the invention the agent is injected into the tree under a variable pressure profile until the fastest injection time is obtained.

Abstract: A material processing method produces a fiber product by anaerobic digesting of input material such as dairy flush to produce a gas product and a liquid and solid fiber product, by thereafter separating liquid components and solid fiber components of the liquid and solid fiber product, and by thereafter aerobic conditioning of the solid fiber components to derive the fiber product useful as a soil amendment in the manner of peat moss.
