Abstract
An absorption device for use with a waterless urinal comprises an exchange container containing at least one ion exchange resin. The exchange container comprises a housing and at least one resin support. The ion exchange resin can be a cation exchange resin that removes calcium and magnesium ions from urine. The ion exchange resin can be an anion exchange resin that removes anionic pharmaceuticals from urine. The ion exchange resin can be a hybrid anion exchange resin that removes phosphorous comprising anions from urine. The absorption device permits the removal of cations that result in scale and blockage of waterless urinal drain pipes and removes ions that otherwise would require treatment at wastewater treatment facilities.
