Water filtering system

摘要

Grey water is conveyed to a tank, passed through filters, and pumped to an irrigation system. A floating spray component is provided in the tank to automatically backwash the filters to prevent clogging, moving up and down as the level of water in the tank changes. The filters can be cylindrical and oriented vertically, and a removable, internal filter cartridge can mount the filters. The filters can be accessed through a top, above ground cap, and the carriage can be removed for access to other parts by removing a larger lid.

1. A grey water filtering system comprising:
a tank having an internal cavity for receiving water, an inlet for conveying water into the tank, and an outlet for conveying water out of the tank; a filter assembly received in the tank and including a filter disposed between the inlet and outlet and constructed and arranged such that water passing from the tank inlet to the tank outlet passes through the filter, the filter having an inlet surface exposed to water from the tank inlet and an outlet surface exposed to water that has passed through the filter; and a backwash assembly including at least one nozzle, a float carrying the at least one nozzle for movement up and down in reaction to an increase and decrease in the level of water in the tank, and a pump supplying water under pressure to the at least one nozzle, the at least one nozzle being mounted to direct pressurized water at the outlet surface of the filter for a backwash cleaning effect.
