A desalination system () having an intake unit () providing seawater to a pre-treatment unit () connected to a reverse osmosis (RO) desalination unit () and a post treatment unit (). The desalination system () is configured to operate without any external addition of chemicals to simplify logistics and regulation concerns. The units of the system are configured to prevent biofouling, scaling and corrosion by mechanical and biological means including high flow speeds, biological flocculation of colloids, and making the water entering the RO units inhospitable to bacteria and other organisms that cause biofouling, hence preventing their settlement and removing them with the brine. Recovery rate is lowered and energy is recovered to increase the energetic efficiency and minerals that are added to the product water are taken from the brine.

Chemical free and energy efficient desalination system

A drive shaft system () comprising a shaft () connected to a motor via a coupling () and arranged to transmit a rotary movement from the motor to the rotor, at least two supports () arranged to position the shaft within a shaft housing (), each support comprising at least one bearing (), and at least one forcing element () arranged to force at least one of the supports against either an inner side of the shaft housing or an outer side of the shaft (); such as to prevent turning and radial movements of the supports within the shaft housing while enabling axial movement of the shaft within the shaft housing. The bearings may be forced at either their inner or outer rings, and may be enclosed in a bearing housing () for protection and stiffness.
