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.
