Green Sludge Processing Technology

A significant problem in the management and treatment of sewage is the dewatering and disposal of sludge.

The quantity of wastewater sludge generated will increase significantly in the coming years.

The management of wastewater sludge poses economic, planning and environmental challenges.

A Green Solution To Sustainable Sewage Treatment.

In accordance with the waste hierarchy, the minimisation of sludge is the next most preferred waste solution after prevention.

There is potential to reduce the volume of both municipal and industrial sludge for transport by 70% to 80% by optimising sludge thickening. Traditional sludge dewatering techniques has a relatively high operational cost due to the labour, power, machinery, chemicals and capital maintenance requirements. In addition transportation is a significant part of sludge management in terms of environmental impacts and cost.


Premier Base has developed a green innovative approach to processing Waste Activated Sludge that doesn’t require energy or chemicals. We have developed a unit in which sludge migrates to the top with water underneath. This process occurs because of our patented design and does not require the use of a dissolved air flotation system or polymer dosing units. The process which involves filling and decanting receives sludge at 1%/2% and dries up to 80% depending on climate conditions.
