Abstract

An efficient, low pressure drop biocide cartridge is provided for destroying viral and bacterial pathogens in water from untreated water sources along a lengthened flow pathway including a critical plenum for controlling the speed of water throughput. In a first pathway, water is percolated through a turbulatable bed of biocidally-effective material. In flow pathway, channeling and pressure drop are reduced by radial flow across a columnar bed presenting a large surface area at an outer diameter. The cartridge may be connected with a lightweight hand-held pump. A sealing strap is provided for wet storage of any biocide cartridge.
