Vitec 5000

Vitec 5000 is a highly effective liquid antiscalant developed to prevent scaling on membranes. It can also be used as
a dispersant. Vitec 5000 can 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.

Vitec 5000 achieves optimum performance when injected downstream of the multimedia filter and upstream of the candle filter. Sufficient mixing must be achieved.

Vitec 5000 should not be diluted more than 1:10. Thus, an optimal effect of the bacteriostatic agents contained in the Vitec 5000 is achieved. Bacterial growth in the container and storage tank is prevented by observing this procedure.

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 5000 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.

Physical properties:

Appearance:  clear, slightly yellowish liquid
Density: 1.17 +/-0,05
pH: 2.0 to 3.0


Technical properties:
Vitec 5000 Antiscalant offers a variety of application possibilities:

Prevents RO membrane scaling caused by the following substances:
+ Calcium carbonate (CaCO3)
– Langelier Saturation Index (LSI) < 2.8
– CCPP > 900
+ Calcium sulphate (CaSO4)
– up to 30 times oversaturation
+ Barium sulphate (BaSO4)
– up to 105 times oversaturation
+ Strontium sulphate (SrSO4) – up to 20 times oversaturation
+ Calcium fluoride (CaF)
– up to 1000 times oversaturation

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

Compatible with polyelectrolytes

Complex formation with heavy metals, thus heavy metal fouling reduced

Compatible with all standard RO membranes
