Access control is really a system enabling authorities to manage usage of areas and resources in a very given physical facility or computer-based information system. Access control is, in reality, perhaps the most common, everyday phenomenon. For example, a lock over a car door is basically a sort of access control. The PIN with a bank's ATM method is another way of access control. Even nightclub bouncers, waiting in front of the door, are another instance of (perhaps) a more primitive mode of access control. Using an access control mechanism is important when persons seek to secure confidential, important, or sensitive information and equipment.
Self-cleaning filter features: continuous water supply is carried out in the backflush, and the whole backwash is achieved in every point of the suction net filter. The anti-flushing is only a small local pressure change between the suction nozzle and the fine filter screen, while the movement of the collector and hydraulic cylinder does not affect the normal water supply. At the same time, the amount of water consumed during the backflush is very small, with the flow rate of 300m3/ h. For example, the reverse flushing flow rate is 35-40m3 / h, the anti-flushing time is 7-15 seconds, and the backwash amount is 80-160L
