Abstract: Method of waste water/water treatment in a submerged membrane bioreactor is disclosed. The bioreactor includes a tank containing a mixed liquor having microorganism; porous carriers in the mixed liquors; and a filtration module immersed in the mixed liquor and having a permeate side into which fluid can flow only through the filtration module. The method includes introducing an influent into the tank; applying a negative pressure source to the permeate side so that liquid in the tank penetrates the filtration module into the permeate side and flows out from the tank; and aerating the mixed liquor in the tank so that the porous carriers keep contact with the filtration module, and thus reduce fouling of the filtration module.

Abstract: A method of wastewater/water treatment includes introducing an influent into a reactor so that a portion of contaminants in the influent is decomposed by microorganism in the reactor during a retention time of the influent in the reactor, and thus an effluent has a less amount of contaminants in comparison with the influent. The microorganism is grown fixedly on modified porous carriers in the reactor. The modified porous carrier contains a polymer foam and adsorbent particles entrapped in pores of the polymer foam, so that the modified foam not only has a large specific surface area, but also characteristics such as water affinity or an affinity to a certain type of contaminants. As a result, the efficiency of reducing contamination in the influent water is enhanced.

Abstract: The present invention provides a floated biological treatment apparatus and a process for purifying refractory wastewater or raw water for drinking water. The treatment apparatus of the present invention includes a supporting plate for dividing the treatment apparatus into upper and lower portions. The upper portion is formed into a reactor, and porous compressible carriers are filled with the reactor in an amount of 80 vol % to 100 vol % of the reactor volume. The lower portion is provided with a liquid inlet for introducing the refractory wastewater or raw water and a gas inlet. The reactor is provided with at least one top carrier blocking plate at the top, such that the carriers can be limited by the top carrier blocking plate to be retained in the reactor, and the carriers can become a floating state. By means of the process or apparatus of the present invention, the cost for treating refractory organic material can be reduced, the treatment efficiency can be enhanced, and the quality of the effluent can be improved. In addition, since the carriers are in a floating state, they will have the advantages of low abrasion. The clogging problems can be prevented, and the gas and the influent can be evenly distributed.

Abstract: A method of removing arsenic from water by using a reactor that is provided with a fluidized bed of carriers is disclosed. An arsenic-containing influent is mixed in the reactor with a sulfide aqueous solution or metallic salt aqueous solution at a predetermined pH, thereby resulting in formation of crystals of arsenic sulfides or arsenic acid metal salts. The arsenic contained in the influent is thus removed by crystallization. An effluent with a reduced arsenic content is discharged from the reactor. The carriers, on which the crystals are formed, are periodically removed from the reactor which is replenished with fresh carriers immediately after.
