Precipitation of phosphates
Precipitants for all situations
Proven primary precipitating agents from VTA based on iron, aluminium or iron/aluminium reliably remove phosphorus compounds from wastewater.
Dissolved phosphates are converted into undissolved phosphates and allowed to bond firmly with the sludge floc, optimizing sludge structure and sedimentation properties.
VTA also produces special alkaline precipitating agents for wastewater with low pH, low water hardness or weak acid neutralizing capacity.
