摘要： A method for cyanobacteria removal in an aqueous solution, includes a first main step of determining a percentage of coagulable dissolved aromatic organic matter to remove corresponding to a cyanobacteria percentage concentration to remove, a second main step of determining an optimal coagulant dose corresponding to the determined percentage of coagulable dissolved aromatic organic matter to remove and a third main step of applying the optimal coagulant dose as the adjusted coagulant dose for cyanobacteria removal. The invention may comprise an evaluation of cyanobacteria concentration in the aqueous solution. The invention may comprise a metabolite removal step adapted for removing dissolved cyanobacteria metabolites, comprising applying a powdered activated carbon dose/contact time couple as by determining at least one Freundlich coefficient for each metabolite type in the aqueous solution.

摘要： A particle measuring apparatus is provided that has improved measurement accuracy regardless of particle diameters and that ensures prompt measurement. A particle measuring apparatus has: first and second particle counters that obtain a number of particles that are contained in water that flows in a predetermined section of an ultrapure water production apparatus; and particle number calculation means that calculates the number of the particles that are contained in the water that flows in the predetermined section for each particle diameter range based on measurement results of the first and second particle counters. The first particle counter and the second particle counter have different counting efficiencies.

摘要： A treatment device for treating a mixture of at least a liquid, organic solids and inorganic, mineral solids, includes a container for receiving the mixture. The container tapers in a funnel shape in a direction of a longitudinal axis of the container. An inlet tangentially supplies the mixture to the container. An outlet discharges the liquid essentially containing the organic solids from the container. A discharge apparatus serves for discharging the inorganic, mineral solids. The treatment device also includes a sleeve adapted to guide the mixture between an outer wall of the sleeve and an inner wall of the container and to guide the liquid containing the organic solids within an inner wall of the sleeve for discharge from the outlet.

摘要： Provided is a biochar-anaerobic membrane biological treatment system and process. The system mainly includes a reaction tank, a membrane module, a macroporous gas distribution device, low-temperature pyrolysis biochar. The application of the process to sewage treatment shows that: under the conditions that the hydraulic retention time is 3.2-7.2 h, the membrane flux is 12.0-17.8 L/m2/h, and the sludge concentration of 7.2-15.6 g/L, multiple objectives of promoting organic micropollutants (OMPs) biotransformation, accelerating methane production and strengthening membrane fouling control were achieved. The system improved OMPs removal efficiency by more than 20%, decreased membrane fouling rate by 50%, and reaching an organic matter removal efficiency of more than 86% at low temperature. The system and process solve the problems of poor OMPs removal efficiency, serious membrane fouling, and low methane yield at low temperature in the anaerobic membrane biological treatment system.

摘要： Conventional liquid cyclone devices tend to break flocs and thus cannot be used for floc separation. Further, there are no ballast water treatment devices that can simultaneously remove plastics and microplastics floating in the sea. In addition, there are no ships or ship operation methods that address the problem of pollution due to plastics and microplastics floating in the sea.
To achieve cyclone separation of a fluid including easily broken flocs, flocs that include a magnetic body are guided by means of centrifugal force and magnetic force to a flow in the vicinity of an outer shell of a cyclone, then to a channel between an inner shell and the outer shell, and discharged from a lower outlet. The inner shell prevents an upward flow from affecting the flocs, making it possible to achieve reliable separation of the flocs.

摘要： A composite is synthesized by pyrolysis of a mixture of tannin and melamine. The synthesis process comprises dissolving the tannin and the melamine in water to form a homogeneous solution; evaporating the solution to yield a dry solid; and subjecting powders of the dry solid to a heat treatment at a temperature for a duration of time effective to produce the composite.
