Z-XM™ Nitrate Treatment System
WRT’s nitrate removal system consists of utilizing a regenerable ion exchange media. Currently the media, trade named Z-XM™ is a nitrate selective synthetic ion exchange flow-through media. The media is a specialized strong base anion exchange resin of styrene-divinylbenzene base structure. The media is contained in a screened pressure vessel wherein untreated water is pumped down flow packed bed through the vessel for the service period. Following the recommended service interval measured in volume throughput, the pressure vessel is placed in a batch regeneration mode. Regeneration consists of contact with a calculated volume of concentrated sodium chloride brine for a […]
Z-XM™ Perchlorate Treatment System
WRT’s perchlorate removal system consists of utilizing a non-regenerable ion exchange media, which after exhaustion is disposed of via incineration (preferred) or suitable landfill disposal. Currently the media, trade named Z-XM™ is a perchlorate selective synthetic ion exchange flow-through packed bed downflow media. The media is a specialized strong base anion exchange resin of styrene-divinylbenzene base structure. The media is contained in a screened pressure vessel wherein untreated water is pumped through the vessel for the service period. Following the recommended service interval measured in bed volume (BV) throughput or based on treated water discharge sampling, the spent media is […]

PROBLEM: Feed concentration of uranium in water source was as high as 370.0 ppb, exceeding MCL standard of 30 ppb. RESULTS: Pilot unit reduced uranium levels to an average of 1.2 ppb. Mountain_Water_Conifer_CO
City of Lawrenceville, Georgia
PROBLEM: Uranium levels in water source were as high as 241 pCi/L, exceeding the MCL standard of 20 pCi/L. RESULTS: Pilot unit reduced uranium levels to an average of 0.7 pCi/L Lawrenceville_Pilot
City of Grand Island, Nebraska
PROBLEM: Uranium and gross alpha levels in water source were as high as 31.0 µg/L for uranium, and 45.0 pCi/L for gross alpha, both exceeding the MCL standard of 30 µg/L for radium and 15 pCi/L for gross alpha. RESULTS: Pilot unit reduced uranium levels to an average of 0.2 µg/L and gross alpha levels to an average of 3.2 pCi/L. Grand_Island_NE

PROBLEM: Uranium, arsenic and gross alpha levels in water source were as high as 99.9 µg/L for uranium, 13.5 µg/L for arsenic and 57.0 pCi/L for gross alpha; all exceeding MCL standards. RESULTS: Pilot unit reduced uranium levels to an average of 0.2 µg/L, arsenic levels to an average of 1.2µg/L, and gross alpha levels to 2.6 pCi/L. Schurz_NV
Borough of Hopewell, New Jersey
PROBLEM: Uranium, radium and gross alpha levels in water source were as high as 43.7 pCi/L for uranium, 13.6 pCi/L for radium and 85.6 pCi/L for gross alpha; all exceeding MCL standards. RESULTS: Pilot unit reduced uranium levels to an average of 2.6 pCi/L, radium levels to an average of 1.3 pCi/L, and gross alpha levels to 5.5 pCi/L. Hopewell_ Pilot_Study_Report_CONDENSED
City of Hastings, Nebraska – ARS Well No. 27
PROBLEM: Uranium and gross alpha levels in water source were as high as 23.0 µg/L for uranium, and 20.2 pCi/L for gross alpha, exceeding the MCL standard of 15 pCi/L for gross alpha. RESULTS: Pilot unit reduced uranium levels to 0.0 µg/L throughout the study, and gross alpha levels to an average of 2.4 pCi/L. Hastings_ Pilot_Study_Report_FINALCondensed29Jan18
