Water disinfection method and apparatus

An apparatus for disinfecting water, the apparatus comprising:

• a top disinfection section comprising a water distributing tray and a first filtration system, the water distributing tray comprising a plurality of parallel slots and the first filtration system comprising a plurality of filter boxes arranged in a closed path, wherein:
• the water distribution tray is configured to pass the water though the parallel slots into the plurality of filter boxes first passing the water through the water distributing tray;
• each filter box from the plurality of filter boxes comprises a respective strainer at a bottom of the filter box;
• a respective plurality of parapet walls attached seamlessly to an outermost circumference of the respective strainer;
• an inclined elongated part attached to a first parapet wall from the respective plurality of parapet walls;
• and
• the first filtration system is configured to:
• move the plurality of filter boxes cyclically along the closed path;
• filter the first set of particles from the dispensed water utilizing strainers in the plurality of filter boxes due to the movement of the plurality of boxes;
• pump a high-pressure stream of water to a back side of the respective strainer;
• and discharge particles from the first set of particles to a sewage from a bottom of a respective filter box of the plurality of filter boxes utilizing the high pressure stream;
• a bottom disinfecting section comprising a plurality of filtering layers configured to:
• filter a second set of particles from the water by passing the water through the plurality of filtering layers to produce filtered water;
• and
• remove the second set of particles settled in the bottom disinfection section utilizing a vacuum-cleaning system;
• and
• a plurality of fans configured to expose the filtered water to a high-pressure stream of air to reduce microorganisms and ammonia gases existing in the filtered water by aerating the filtered water.
