Vitec 1141

Vitec 1141 is a powerful, wide spectrum, liquid antiscalant and dispersant that is highly effective at low dose rates and in a wide range of feedwaters such as brackish, wastewater, and seawater. Vitec 1141 is used on waters where the silica and sulfate limits exceed the limits for Vitec 3000 but do not require a specialized antiscalant like Vitec 4000 or Vitec 7000. Vitec 1141 is also good on feedwater sources where particle breakthrough is common due to pretreatment issues.
