An object of the present invention is to provide a water treatment system in which explosions can be prevented even when filtering water to be treated that is able to generate flammable gas. A water treatment system according to an embodiment of the present invention includes a water-to-be-treated tank which stores water to be treated, a crossflow-type filtration membrane module which filters the water to be treated, a supply passage through which the water to be treated is supplied to the filtration membrane module from the water-to-be-treated tank by using a supply pump, and a recirculation passage through which the water to be treated is recirculated from the filtration membrane module to the water-to-be-treated tank. The supply passage is provided with an aspirator which mixes a gas with the supplied water to be treated, the gas being recirculated through the recirculation passage to the water-to-be-treated tank together with the water to be treated. The water-to-be-treated tank has an upper space provided above the liquid surface of the stored water to be treated, the upper space being hermetically filled with an inert gas. The water-to-be-treated tank is further provided with a gas transport passage through which the inert gas is supplied from the upper space to the aspirator.

A gas infusion waste water treatment facility having an apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. The facility creates absorption of increased gas concentration containing an oxygen atom into the fluid from 10% to at least 500%.

A membrane filter module configured to treat a liquid contained in a tank at an ambient pressure. The module may have a header, with a bundle containing a plurality of substantially vertical hollow fiber membranes, wherein a lower end of each hollow fiber membrane is fixed in the header. The module may also have a gasification device adapted to periodically generate a gaseous bubble and configured to release the gaseous bubble within the bundle. The module may further have an enclosure that substantially surrounds the bundle that extends from a lower region to an upper region of the membrane bundle, wherein the enclosure is configured to retain the liquid introduced into the enclosure such that the liquid surrounds the membrane bundle. The gaseous bubble has a cross-sectional area that corresponds with a cross-sectional area of the enclosure, such that the cross-sectional area of the gaseous bubble occupies substantially the entire cross-sectional area of the enclosure as it flows along the bundle.

Disclosed is an energy hydrogen water dissolving device that passes a clean water source through a pressurized pump. A part of the water is sent to a hydrogen production equipment and decomposed into hydrogen and oxygen, and the other part of the water is driven to an energy hydrogen water dissolving and storage tank. The oxygen formed by the hydrogen production equipment is discharged to the outside or returned to the clean water source, and the hydrogen formed by the hydrogen production equipment is connected and sent to an input end of the pressurized pump, pressurized and mixed uniformly by the pressurized pump and outputted to the clean water, so that the water liquid entering into the energy hydrogen water dissolving and storage tank becomes high dissolution hydrogen water. The energy hydrogen water dissolving and storage tank contains an energy mineral, a hydrogen molecule mineral and a terminal filter, and the water liquid discharged from the energy hydrogen water dissolving and storage tank is formed into healthy drinking water with tiny water molecules, weak alkaline, high negative potential and high dissolution hydrogen molecules

An aeration control system and method for wastewater are provided. The aeration system, which is connected to an aeration device in an aeration basin, includes a plurality of water quality detectors, at least one pollutant estimate model, and a processing unit. The plurality of water quality detectors are configured to acquire a plurality of water quality data. The plurality of water quality data includes a pre-aeration water quality data and a post-aeration water quality data. The pollutant estimate model is configured to generate a pollutant data according to the pre-aeration water quality data. The processing unit is configured to generate an aeration quantity according to the pollutant data, the post-aeration water quality, and an effluent water quality setting, and transmitting the aeration quantity to the aeration device.

A separation membrane element including a pair of separation membranes containing two separation membranes arranged so that the filtrate-side surfaces thereof are disposed in mutually opposed relation, and a plurality of resin members bonded to both of the mutually opposed filtrate-side surfaces, a peripheral edge of the pair of separation membranes being sealed.

This disclosure relates to an apparatus and method for analyzing an influence variable on membrane fouling of a seawater desalination system, wherein influence variables other than variables having a low degree of influence, among variables affecting the membrane, are selected, and the influence thereof on membrane fouling is used to derive an equation. The apparatus includes a variable storage unit configured to store variables affecting membrane fouling of a seawater desalination system, a dominant variable selection unit configured to select at least one dominant variable among the variables through at least one algorithm, and an equation derivation unit configured to derive a specific equation based on a correlation between the selected dominant variable and the membrane fouling.

A bioreactor has a biofilm that receives a gas through a supporting membrane and another biofilm attached to an inert support. The first biofilm is aerated through the membrane and provides nitrification. The other biofilm has an anoxic or anaerobic zone and provides denitrification. A module useful in the bioreactor has cords potted in at least one potting head. Optionally, some or all of the cords have a gas transfer membrane. The module may provide inert supports, active gas transfer supports or a combination of both types of support. Multiple modules may be assembled together into a cassette, the cassette providing inert supports, active supports or a combination. The module or cassette may have an aerator for mixing or biofilm control.
