A method for treating water containing pollutants, water cleaning reactors, and water cleaning assemblies

A water cleaning assembly comprising,

• a water cleaning reactor comprising, magnetoelectric particles, one or more coils which can conduct current. wherein said one or more coils are arranged with respect to the magnetoelectric particles such that the magnetoelectric particles are submersed in a magnetic field generated by the one or more coils when the one or more coils conduct current;
• a circulation tank which is fluidly connected to the water cleaning reactor, such that fluid can flow from the circulation tank to the water cleaning reactor, and such that fluid which has flowed through the water cleaning reactor can flow into the circulation tank;
• a senor which is configured to sense the level of pollution in a fluid contained in the circulation tank;
• a pump which can pump fluid from the circulation tank to the water cleaning reactor;
• a controller which is configured to operate the pump to pump fluid from the circulation tank to the water cleaning reactor if the sensor detects that the level of pollution in said fluid is above a predefined level.
