WebOvivo’s vast experience in treating sludge from all types of municipal and industrial wastewater systems, in combination with our sludge thickening and dewatering solutions can optimise sludge management and plant operations. Ovivo can assess plant needs based on sludge output, characteristics, and provide customised solutions to minimise the ... WebThickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume. An alternative to gravity thickening is dissolved-air flotation. In this method, air bubbles carry the solids to the surface, where a layer of thickened sludge forms.
