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.VIEW ALL CHEMICALSVIEW SUPPORT SERVICES

Selecting the right cleaning chemicals extends system run times between cleanings, reduces chemical costs and extends productive membrane life and overall system up-time.
Provides a cost-effective solution for biological fouling, which is one of the most challenging issues faced by operators of polyamide membrane separation systems.
Inhibits scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec products help extend system run times, reduce cleaning frequency, and increase the productive life of RO elements.
