Overcoming your challenges
Any industrial process that removes solids such as settlement, flotation or filtration from water and wastewater will, in general, generate a sludge waste stream that needs to be treated and disposed.
In dealing with sludge on site, you’ll face several challenges that we can help you with.
There is a sequential hierarchy that must be applied when considering treatment options for sludge. This includes:
1 – Prevention and minimisation at source
2 – Sludge re-use and recycle
3 – Energy recovery
4 – Treatment and disposal
Sometimes, initial tiers in the hierarchy such as minimisation are just not possible to achieve, which may force you down to lower tiers and ultimately disposal. Sludge is classed as a waste and its handling and disposal are tightly regulated. Depending on the industry sector and processes involved in generating the sludge, it can be contaminated with pollutants that may limit its recycling, re-use or disposal.
This presents its own challenges, which include identifying a viable and sustainable route for sludge disposal that meets the tight legislation imposed by the Regulator. Overheads are also an important consideration, so a major challenge involves driving down the costs associated with the transport and disposal of sludge.
