Vitec 2000

Vitec 2000 is a liquid antiscalant developed to prevent scaling on membranes. It can also be used as a dispersant. Vitec® 2000 an be used concentrated or diluted in a wide range of applications. (e.g. surface water and well water)
The exact dosage amounts can be determined with the Avista Advisor calculation program.

Application:
Vitec 2000 achieves optimum performance when injected downstream of the multimedia filter and upstream of the candle filter. Sufficient mixing should be achieved.

Dilution:
Vitec 2000 should not be diluted more than 1:10.

Dosage instructions:
The typical dosing range is between 2 and 5 ppm. The optimum quantity can be determined with the Avista Advisor computer program. Both over- and underdosing can cause unnecessary fouling/scaling of the membrane system. The Avista customer service provides individual support for the compilation of dosage instructions.

Packaging and storage:
Vitec 2000 is available in 23 kg canister, 230 kg drum  and 1100 kg IBC container. The product should be protected from frost during storage as the active ingredient would precipitate under extreme temperatures. Heating of the product and subsequent stirring brings the active ingredient back into solution.

Technical properties:

Vitec 2000 Antiscalant offers a variety of application possibilities:

Prevents RO membrane scaling caused by the following substances:
+ Calcium carbonate (CaCO3)
– Langelier Saturation Index
(LSI) > 3
– CCPP > 900
+ Calcium sulphate (CaSO4)
– up to 3.5 times oversaturation
+ Barium sulphate (BaSO4)
– up to 105 times oversaturation
+ Strontium sulphate (SrSO4)
– up to 35 times oversaturation
+ Calcium fluoride (CaF)
– up to 1000 times oversaturation

Dispersion properties reduce colloids and suspended solids fouling on the membrane surfaces.

Compatible with organic polyelectrolytes

Complex formation with heavy metals, thus heavy metal fouling reduced

Compatible with all standard RO membranes

Working range from pH 2 to 12
