A product and apparatus for cleaning water or industrial and sewage waste water includes a mixture of diatomite that is heated and stirred to impart an enhanced negative electrical charge to the diatomite. A mixture of approximately 50% aluminium chloride (AlCl3) by volume is blended to provide a powder mixture for use as a flocculant in the system. According to a modification, the charged diatomite is instead blended with a mixture of approximately 50% ferric chloride (FeCl3) by volume and is stored in liquid form for later use as a flocculant in the system. From one to five percent, by volume, of polyacrylamide is preferably added to the mixture for use in sewage waste water treatment applications. An efficient system for reacting either the mixture or separately adding the diatomite and the metallic chloride to the water is described.

A polymer membrane for water treatment, characterized in comprising a hollow fiber membrane having a self-supporting design composed of the substantially single principal structural material, with an outer diameter of 3.6 mm to 10 mm and a ratio of outer diameter to thickness, SDR, of 3.6 to 34.

The invention relates to a low-pressure discharge plasma water treating apparatus, mainly comprising a discharge power supply, a high voltage electrode, a reactor, an atomization sprinkler, a water inlet pipe, a water outlet pipe, a water flow monitor, an air exhaust pipe, an air valve, a vacuum pump, a sewage pool and a clean water reservoir. According to the invention, without a water pump, a low pressure environment in the reactor can be maintained via only one vacuum pump under the condition that water flows through the reactor; electro-discharge is carried out in the low pressure environment, and large-volume, high-activity and non-thermal equilibrium plasma is generated; the treating apparatus can effectively remove pollution sources like heavy metal ions, organic matters and microbes in water, has high treatment efficiency, is generally applicable to sewages having different pollution degrees and produced by different industries and provides activated water for special industries. The invention further relates to a plasma water treating method which realizes low pressure discharge under the condition that a water cycle between the interior of the reaction chamber and the outside is maintained without usage of a forced exhaust type water pump. With the method, system energy consumption is greatly reduced.

Disclosed are a water treatment apparatus using underwater plasma discharge and a water treatment system using the same. The apparatus includes a reactor having an inlet through which raw water flows in and an outlet through which purified water flows out, a ground electrode provided at a first side of the reactor, and a plasma electrode module provided at a second side of the reactor and configured to generate plasma. With plasma generated through underwater discharge, it is possible to decompose or remove organic substances and microorganisms present in raw water.

The invention discloses a current controller suitable for controlling a fluid to flow in multiple directions. The current controller comprises a first current control element, a second current control element and a shell; the second current control element is arranged on the first current control element and accommodated in a first accommodating chamber formed in the shell; and users can rotate the second current control element to selectively communicate each channel of the first current control element with a channel of the second current control element so as to control flowing of different water currents. The current controller has such advantages as simple structure, low production cost, convenience in use and reliable performances.

The invention discloses an anti-blocking method applicable to a circulation water loach breeding pond bottom drain. The anti-blocking method comprises the steps of arranging a sewage cleaning machine in a gap of escape-proof fences of a sewage draining machine and enabling scraping teeth protruded out of the periphery of the sewage cleaning machine to be embedded with gaps of the fences of the sewage draining machine one by one; connecting a guide rod which is welded with the center of the sewage cleaning machine and straightly led to the water surface and a connection rod to a motor which is arranged at the top end of a main frame; and dragging the guide rod and the connection rod through the motor to enable the sewage cleaning machine to move up and down, automatically clean blockage substances and retain smooth water drainage and normal circulation. The anti-blocking method applicable to the circulation water loach breeding pond bottom drain is applicable to industrial circulation water breeding of small varieties comprising loach and suitable for cleaning sediments which block water drain gaps of the bottom drain; and through the method, the anti-blocking problem of the sewage draining machine in small fish circulation water breeding can be effectively solved. The method is simple; devices are convenient to mount and manage; the sewage cleaning machine and a raw sewage draining device are only required to be matched and fixed wholly; the devices are capable of automatically operating and saving labor; and the device are excellent in economy and practicability.
