Water and Air Quality Control with a Coil Type Filter

摘要

A coil type filter has been developed and experimentally evaluated for environmental control. The filter comprises a spiral wound coil having an inlet and an outlet at opposite ends. The inlet and outlet apertures have screens positioned to retain the filtering element within the coil. Couplings are provided on the exterior of the coil at each end for connection to other portions of a fluid flow system. The interior of the coil is filled with adsorbents, absorbents, ion exchange resins, and filter media which perform the purifying operation. The spiral wound coil may be mounted within a housing with the inlet and outlet both extending outwardly from the same portion of the housing. A thermostatically controlled heating element may be mounted within the housing to control the temperature of the fluid within the coil. It has been proven experimentally that the newly developed coil type filter can adequately remove toxic organics and heavy metals from water. Other potential applications in air quality control and resources recovery, and possible regeneration procedures are proposed and discussed.
