    Abstract: A filter unit that includes a slide assembly and a head assembly. The slide assembly is moveably mounted to the head assembly. The head assembly is configured to receive an end portion of a filter cartridge in releasable engagement. The slide assembly is movable between a first position in which the slide assembly prevents disengagement of the filter cartridge from the head assembly, and a second position in which the filter cartridge is permitted to disengage from the head assembly. In the second position, the slide assembly maintains engagement with the head assembly until an external force is applied by engagement of the filter cartridge with the slide assembly when removing the filter cartridge from the head assembly.

    Abstract: Provided are water purification systems that are suitable for retrofitting clay pot gravity feed systems. In general, the systems comprise a typical clay pot gravity filter with upper (treatment) and lower (filtrate) chambers, a filter block, such as a gravity flow carbon block, and a flow barrier to prevent or allow water in the upper chamber from contacting and flowing through the block. The system could also include an optional membrane filter. Water is added into the top chamber while the flow barrier is closed so that the water cannot contact or flow through the carbon block. A treatment agent such as chlorine is added to the water to disinfect. After an appropriate contact time, the flow barrier is opened to allow water to flow through the carbon block to the lower chamber. The filter block can remove cysts and chlorine, producing microbiologically safe water. An optional membrane can be added downstream of the carbon block for improved reduction of microbes and particles.

    Abstract: A water-on-water filtration system that includes a filter member and two storage vessels. The system includes a plurality of valves that are controlled to place a first of the storage vessels in a fill state in which the first storage vessel is being filled with filtered water, and concurrently place the second of the storage vessels in a service state in which filtered water held in the second storage vessel is delivered as an output of the filtration system. The filtration system can be configured to supply a constant output of filtered water to meet a constant demand while using a relatively small filter member and relatively small storage vessels.
