Systems for and methods of monitoring and analyzing deposit in an industrial water system are provided. The methods comprise heating a substrate while the substrate contacts industrial water in the industrial water system to form deposit on the substrate. A series of digital images of the substrate while the substrate contacts the industrial water in the industrial water system is created. A region of interest in the series of digital images of the substrate is defined. A deposit feature in the region of interest in the series of digital images of the substrate is identified. The deposit feature in the region of interest in the series of digital images of the substrate is analyzed to determine a deposit trend of the substrate in the industrial water system. Generally, the systems are configured so as to be capable of carrying out one or more of the methods.

A photodynamic composite including a porphyrin having four quaternized nitrogens, wherein the porphyrin is covalently bonded to a polymer containing reactive amines covalently bonded to a solid-state support is claimed. A method for sanitizing contaminated water is claimed including exposing the contaminated water to the photodynamic composite, in the presence of light and oxygen, wherein, a sufficient quantity of singlet oxygen and super oxide anions is provided by the chemical reaction of the light and the photosensitizer to destroy the pollutants or pathogens present in the contaminated water and to oxidize organic contaminants into carbon dioxide and water; thereby rendering the water potable.

The present invention discloses a preparation method for the plant-based nano corrosion inhibition bactericide for oilfield, comprising the following steps: Step 1. Prepare the aloin liquid; Step 2. Stir the carbon nanotube, hydroxyethyl methacrylate and acrylic acid to react for 4 h at a constant temperature of 80° C. to get the carbon nanotube after fiber treatment, namely the modified carbon nanotube; Step 3. Mix the aloin liquid with imidazoline-ammonium-salt, add acetonitrile, and then add modified carbon nanotube, increase the temperature to 95° C. stir and react for 12 hours, and filter after naturally cooling down to room temperature and get the carbon nanotube loaded with bactericide; Step 4. Stir the carbon nanotube loaded with bactericide, diphenylmethane diisocyanate and polycaprolactone to react for 6 hours at a constant temperature of 95° C. and in the reaction process, continuously inject helium to get the target bactericide.

Various embodiments of the present technology provide methods and systems for soil enrichment. The systems may comprise a bioreactor system coupled to an initial treatment system for the cultivation of a live microorganism culture containing organic nutrients on an agriculturally effective scale. The systems may be automated and/or portable for practical applications onto target fields. The live microorganism culture may be delivered onto the soil of the target fields, enriching the soil with the organic nutrients that become bioavailable to crops growing in the soil. The soil enrichment system may provide a sustainable approach to agriculture that may efficiently enhance the natural processes of the native soil of any crop.

An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system and a recirculation loop to the dilution reservoir for enhanced mixing of the dilute concentrate. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.

A treatment for a large body of water to make the water suitable for recreational purposes is disclosed. A sedimentation zone and a dissipation zone are designated in the water body. A disinfection method based on a CT index and a flocculant composition are utilized in the sedimentation zone to aid in the settling of different microorganisms and/or contaminants. Also, the water in the sedimentation zone is minimally disturbed to facilitate the sedimentation process. A permanent chlorine residual is maintained in the dissipation zone by adding an efficient amount of a chlorine disinfectant such that at least a 0.5 mg/L free chlorine level is maintained in the water volume. Water is injected into the dissipation zone by means of one or more inlet nozzles. Along with natural currents produced by winds and water temperature differences, a water dissipation pattern from within the dissipation zone into the sedimentation zone is generated.
