Biosolids & Sludge Dewatering Services


What Are Biosolids & Sludge?

Biosolids are often confused with sludge so we are here to clear up your misconceptions so you can book the correct service. So what’s the difference? Well sludge contains untreated solids that often remain after the wastewater treatment process and biosolids are the products of the pre-treatment phase at wastewater treatment plants.

Efficient pre-treatment digests and breaks down the sludge, killing bacteria and eliminating any bad odours while retaining nutrients of value. Biosolids are carefully handled and tracked to ensure that they comply with all health and safety regulatory requirements.

What Is Sludge Dewatering & Why Is It Required?

Sludge dewatering is necessary for waste minimisation. Sludge dewatering splits sludge into liquid and solid parts. Numerous sludge dewatering technologies exist, including plate & frame and belt philtre presses, centrifugation, and geomembranes. There are other solutions available aside from these.

It is necessary to remember that dewatering is not intended to treat the sludge or liquid, it removes only the solid and liquid components so that the different phases for final disposal can be treated more cost-effectively and with better efficiency. When the sludge has been dewatered, both solid and liquid components may contain pollutants and separation of the components may be required. 

Sludge dewatering aims at reducing waste and achieving overall cost-efficiency for disposal. It can also help with corporate sustainability goals. In general, both the public and private sectors are expected to dispose of sludge in a way that is approved by regulatory bodies and is compliant with their own organisational and environmentally friendly standards.

Sludge dewatering is usually based on reducing the mass and size of the sludge in order to reduce the cost of disposal-including transport. The removal of water is the primary means of minimising volume until waste from sludge can be treated or disposed of in the most efficient way. 


Why Are Biosolids Dewatering Services Necessary?

Since it contains nitrogen, phosphate and sulphur and other big crop nutrients, biosolids when processed it can be used as fertilisers. According to the EPA, when used in agriculture, biosolids that meet strict criteria and good application rates have been shown to ‘produce significant improvements in crop growth and yield.

Types of Dewatering Services?

  • Filter Press Dewatering

  • Geomembrane Dewatering

  • Centrifuge Dewatering

  • Belt Presses Dewatering

Sewage sludge treatment for reuse is called sludge processing. The aim of sludge production is often to lower the amount of sludge and to reduce the amount of contaminants to establish a safe product where its disposal to land can be considered.

A side objective is to produce biogas for the production of energy and/or to retrieve quality products such as struvite (phosphorus). For these purposes, there are several ways of treating sludge, the treatments all typically involve thickening, dewatering and a step such as anaerobic digestion, thermal treatment and composting.



What Are The Different Types of Dewatering Services?

Dewatering systems are used to reduce groundwater levels and boost the working conditions in low-lying excavations, usually less than 6 metres in depth. A variety of techniques, such as staggered and multi-tiered dewatering systems can be used for deeper excavations.
