摘要： A control method for a water purifier includes establishing a first cleaning passage which communicates a scale inhibiting mechanism with an RO membrane element of the water purifier and through which the scale inhibiting mechanism cleans the RO membrane element for a first preset time. The method additionally includes establishing a draining passage which is connected to the scale inhibiting mechanism and through which liquid in the scale inhibiting mechanism is drained out, and establishing a second cleaning passage which is in communication with raw water and through which the RO membrane element is cleaned with the raw water for a second preset time.

摘要： A system and process for removing divalent ions from a MEG feed stream is presented. Embodiments of the system include a chemical treatment tank where chemicals are mixed with the feed stream to form insoluble carbonate and hydroxide salts. The system also includes a solid-liquid separation unit that receives the feed stream from the chemical treatment tank and separates it into a liquids portion containing MEG and a insoluble salts portion. The system may also include washing the insoluble salts portion to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer that receives waste slurry from the solid-liquid separation unit and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal.

摘要： The present invention concerns a method of reducing fouling of ceramic membranes by adding an effective amount of a tannin polymer to SAGD process water. Additionally, a cationic and/or an anionic flocculant can also be added to treat the process water. Once the process water is treated, the solids are then separated out and the resulting clean process water is then passed through a ceramic membrane. Typically, the tannin polymer used in treating the process water is comprised of a Mannich reaction product of an amine, an aldehyde, and a tannin. The components are reacted at an acidic pH wherein the molar ratio of amine to tannin present is from about 1.5:1-3.0:1. Exemplary tannin/amine/formaldehyde compounds include tannin/melamine/formaldehyde polymers, and tannin/monoethanolamine/formaldehyde polymers.

摘要： The present invention provides a membrane filtration system (1) including: a filtering membrane portion (3) for removing impurities in feed water; a drain line (16) for draining a part of concentrate from the filtering membrane portion (3) to an exterior of a system; a concentrate return line (17) for returning a remainder of the concentrate from the filtering membrane portion (3) to an upstream side of the filtering membrane portion (3); a return flow rate adjusting portion (28) for concentrate provided in the concentrate return line (17); and a control portion (30) controlling the return flow rate adjusting portion (28) based on a drain flow rate of the concentrate or a flow rate of product water from the filtering membrane portion (3). With this construction, it is possible to suppress wasteful power consumption in a feed pump (7) for feeding water to the filtering membrane portion (3) and to prevent clogging in the filtering membrane in the filtering membrane portion (3).
