Abstract: The present disclosure relates to a technique for inhibiting biofouling of the surface of a membrane caused by a biofilm, through immobilizing biofilm formation-inhibiting microorganisms to a container in a membrane water treatment process. The present disclosure provides a non-hollow/hollow columnar or sheet-like permeable carrier with flowability owing to submerged aeration and a container with biofilm formation-inhibiting microorganisms immobilized therein, comprising biofilm formation-inhibiting microorganisms immobilized in the carrier. The present disclosure also provides a membrane water treatment apparatus comprising a reactor accommodating water to be treated, a membrane module for water treatment and a container with biofilm formation-inhibiting microorganisms immobilized therein placed in the reactor.

Abstract: The present invention relates to a method for obtaining traffic information using the billing information of a mobile terminal. A specified number of a mobile terminal is obtained from billing information necessary for performing a billing operation when a telephone call is made using the mobile terminal on a highway (S61, S62 and S63). The moving time of the mobile terminal between base stations is tracked (S65), such that information of a traffic state on the highway can be obtained in real time (S66). The existing mobile communication network is employed to obtain the traffic information, such that the cost required for operating special vehicles for collecting traffic information and for obtaining traffic information from information providers can be reduced. Customer demand can be met as a measurement operations is continuously carried out and the traffic information abruptly changed is reflected in real time.

Abstract: A technique for inhibiting biofouling caused by biofilms grown on a material surface of a water system where microorganisms exist such as the membrane surface of a membrane bioreactor (MBR) for advanced wastewater treatment is disclosed. Specifically, a magnetic carrier comprising an enzyme for quenching quorum sensing that inhibits biofilm formation, a membrane bioreactor system that can be stably operated without inactivation and loss of enzymes and a method for inhibiting biofilm formation are described.

Abstract: The present invention relates to a method for obtaining traffic information using billing information of a mobile terminal. The method can prevent crosstalk between a vehicle on a highway and a vehicle on a local road parallel to the highway and obtain correct traffic information associated with the highway, when obtaining information indicative of a road traffic state in real time by obtaining a unique number of the mobile terminal from the billing information and tracking a moving time of a corresponding mobile terminal between base stations where the mobile terminal attempts a telephone call on the highway.
