Better than ever before
Soft water, low pH, low temperatures: at the Stanzach treatment plant in Tyrol, optimum wastewater treatment is not exactly easy – but thanks to VTA, it is reliable and larg
Areas of application
Not possible? No such thing!
Individual and customised solutions are our speciality. These include applications for a wide range of uses.
VTA system products
Bulking sludge and scum are feared by the operators of wastewater treatment plants because they lead to sludge outflow, reduced cleaning capacity and high costs.
VTA system products combat or prevent these problems in the long term. They eliminate the unfavourable properties of excessively occurring filamentous bacteria (for example, poor sludge settleability) without at the same reducing their good cleaning performance. The sedimentation rate is improved and the sludge volume index is reduced.
The VTA range also includes system products for increased decomposition of fat. In every case, VTA products ensure optimum and economical plant operation.

Phosphate precipitation
VTA’s tried and tested primary precipitants based on iron, aluminium or iron and aluminium reliably remove phosphorous compounds from wastewater. The dissolved phosphate is converted into undissolved phosphate and stably bound into the sludge floc; sludge structure and settling properties are optimised.
Odour control
Calcoferrit®: Finally an end to unpleasant odors in the sewer!
Dangerous hydrogen sulphide on the Danube!
Odour nuisance? NO thanks!
No chance for dangerous hydrogen sulphide (H2S)
Sludge conditioning
EFFECTIVE DEWATERING REDUCES COSTS
VTA has a broad spectrum of solid or liquid polymer products in its range.
As flocculation agents, they optimise the dewatering and thickening of sewage sludge for recycling or disposal. This ensures higher dry substance content and significantly reduces disposal costs.
