COMPACT BIOCIDAL WATER PURIFICATION SYSTEM

摘要

A biocidal water purification apparatus exposes water to radiation to eliminate viable species. A housing forms a path for water to flow from an inlet to an outlet along a flow path through a treatment zone at which the water is subjected to radiation from a source of radiation, such as beta particles from strontium-90. The exposure to radiation is enhanced using a narrow water flow path lined with the source, especially on oppositely interleaved plates with triangular cross sections, spaced by about 0.25 inch to produce an elongated zigzag path traversed by the water, for example by vertical gravity feed. Additional aspects include other forms of radiation and pre- and post-treatment water treatment or filtration stages and alternatives for continuous, batch and timed-residence water flow management.

主权项

1. A water treatment system for water that can contain undesirable living species, comprising:
a housing forming a path for water caused at least intermittently to flow from an inlet to an outlet along a flow path; wherein at least a portion of the flow path defines a treatment zone at which the water is subjected to radiation from a source of radiation; wherein water passing through the water treatment zone is subject to radiation from the source of radiation at a power level, concentration and exposure time that have a biocidal effect on at least one specie in the water.
