DISPOSITIF ET PROCEDE POUR TESTER DES MODULES DE FILTRATION MEMBRANAIRES, EN PARTICULIER DES MODULES D'ULTRAFILTRATION, DE MICROFILTRATION OU D'OSMOSE INVERSE

摘要

The device comprises a frame (3) in which a modules (2a, 2b, 2c, 2d) to be tested is disposed vertically or horizontally, an inlet (4a, 4b, 4c, 4d) to supply water to be filtered, a filtrate outlet, and retentate outlet. The frame supports a first conduit (7) for a common power supply of the modules in water to be filtered, a second conduit (8) for evacuation of filtrates connected to the filtrate outlet of the modules, and a third conduit (9) connected to the retentate outlet of the modules. The filtration module is installed in the frame of different filtration membranes. The device comprises a frame (3) in which a modules (2a, 2b, 2c, 2d) to be tested is disposed vertically or horizontally, an inlet (4a, 4b, 4c, 4d) to supply water to be filtered, a filtrate outlet, and retentate outlet. The frame supports a first conduit (7) for a common power supply of the modules in water to be filtered, a second conduit (8) for evacuation of filtrates connected to the filtrate outlet of the modules, and a third conduit (9) connected to the retentate outlet of the modules. The filtration module is installed in the frame of different filtration membranes. An adjustable valve is arranged on a line of the filtrate outlet of each module to adjust the flow of the module concerned in an independent way. A flowmeter is also arranged; on the pipe of an outlet of each module; and upstream of connected to the common conduit connected to the filtrate output. The device further comprises a pressure sensor installed on each filtrate outlet of the module and between the outlet and the adjustable valve while other pressure sensor is installed on the first conduit to measure the common pressure of the power supply of raw water, a retro-washing device provided with a retro-washing pump whose output is connected to all modules to be tested by a pipe provided with a valve to the waste pipe of filtrate, and connections for the mounting of four types of different filter modules. The aspiration of the pump is connected to a retro-washing water resource. The common conduit of power supply is connected by a valve to an evacuation of the liquid of retro-washing towards a drain. A cleaning device is provided with a pump whose repression is connected to the first conduit and whose aspiration is connected via valves. An independent claim is included for a process for testing filtration membrane module, which is useful for industrial applications and wastewater treatment.
