Abstract: In a gravity fluid filtration system, upper and lower fluid reservoirs may be mated together. Unfiltered fluid may be supplied to the upper reservoir. One or more filters provide fluid communication between the upper and lower fluid reservoirs. Fluid may pass through the filters into the lower fluid reservoir. The weight of the fluid in the gravity filtration system may be monitored to maximize the fluid flow rate without loss of fluid by supporting the fluid reservoirs on a moveable platform interconnected to a stationary base by a force reactive linkage. Automatic fill components may be provided for automatically actuating a fluid supply valve connected to an unfiltered fluid source. As filtered fluid is withdrawn from the lower reservoir, actuation of the fluid supply valve to an open position may permit unfiltered fluid to be supplied to the upper reservoir. Supply of unfiltered fluid to the upper reservoir may be stopped upon actuation of the fluid supply valve to the closed position.

Abstract: System that monitors and manages a network of smart filtering containers, such as water pitchers with integrated sensors. Measurements are collected from the containers and forwarded to a centralized system, such as an Internet server; data may be analyzed to determine performance modifications or recommendations for selected containers. Centralizing the data enables discovery of patterns and correlations across containers; for example, abnormal measurements from multiple pitchers in an area may suggest contamination of the area's water supply. The centralized system may automatically update settings of containers to optimize their performance. It may send messages to users suggesting different usage patterns or configurations. It may automatically order components such as replacement filters or upgrades.

The feed flows across the filter in a direction parallel to a surface of the filter assembly. The filtrate passes through the filter assembly and the retentate flows through the body chamber in a direction antiparallel to the feed flow through the feed distribution tube and out through the retentate outlet.
