Water treatment device

A water treatment device comprising:

• a main body in the form of a main chamber and having an upper portion, a lower portion, a main inlet for receiving a flow of water into the main body and a main outlet for discharging a flow of water from the main body;
• an insert member disposed within the main chamber at the upper portion, the insert member including a return and bypass channel providing fluid communication between the main inlet and the main outlet;
• a filter assembly disposed within the main chamber and below the insert member, the filter assembly including a treatment chamber in fluid communication with the main inlet, the filter assembly being adapted for filtering water that flows through the filter assembly and including:
• a first filter adapted for filtering coarse pollutants;
• a second filter adapted for filtering standard particulates and soluble pollutants;
• and
• a third filter adapted for filtering fine particulates;
• a base member disposed within the main chamber and below the filter assembly, the base member being adapted for retaining the pollutants and particulates;
• and
• an upflow passage providing fluid communication between the filter assembly and the main outlet via the return and bypass channel, the upflow passage being adapted to direct the flow of water from the filter assembly into the main outlet via the return and bypass channel.
