Sewage Sludge Treatment
Sewage sludge is a by-product of sewage treatment. It takes two forms; semi-solid waste (raw or digested biosolids) and slurry (liquid sludge). Both forms of sewage sludge require further treatment before they can be safely disposed of or recycled.
Our lime solutions play an essential role in sewage sludge treatment. Biocal quicklime (calcium oxide) is widely used for the treatment and hygienisation of raw or digested biosolids. Kalic and Kalic HS liquid lime (suspension of calcium hydroxide) are used to aid the concentration of the solid contents of liquid sludge in preparation for dewatering.
We also offer a range of specialist lime solutions for the pasteurisation of treated sludge; the final stage in a process that turns a potentially harmful waste stream into a safe and natural fertilizer for use on agricultural land.
Renowned for their purity and consistency our sewage sludge treatment solutions:
- Conform to the ADAS Safe Sludge Matrix requirements
- Optimise operational efficiency
- Reduce treatment costs
- Offer a safe, sustainable alternative to other chemical treatments
The Biocal range of quicklime solutions has been specifically developed for the treatment of dewatered or digested biosolids.
KALIC LIQUID LIME
Kalic Liquid Lime is highly stable in suspension and very fast reacting, making it is easy and cost effective to store and use.
KALIC HS LIQUID LIME
Kalic HS is a high solids suspension (45% solids) liquid lime, which combines exceptionally low viscosity with high stability. This makes it ideal for the treatment of industrial effluent, sludge and wastewater.
LIMBUX HYDRATED LIME
The Limbux range includes a comprehensive choice of high quality hydrated limes, including specialist grades to meet specific applications.
