Bio SolidsGet a Quote

SED Services Ltd are proud to work closely with United Utilities Water, taking valuable biosolids to agricultural land.  SED have worked with United Utilities for over 15 years on this project and are now in a key position on their top 50 suppliers list.

Biosolids are produced at Waste Water Treatment plants, which produce either Conventional sludge or Enhanced Sludge.  This waste is treated at United Utilities sites, where pathogens are destroyed enabling this valuable material to be put to agricultural land.  This ethical and beneficial form of waste disposal is applied to agricultural land providing necessary soil nutrition and conditioning properties.

SED have been able to work closely with United Utilities and subsequently with the Environment Agency to develop a sludge to land protocol that is environmentally friendly and beneficial to land.

Details of the types of sludge and treatments it can undergo are detailed on the safe sludge matrix.

What is meant by Conventionally Treated Sludge?

There are a range of different treatment processes used to reduce the fermentability and possible health hazards associated with sewage sludge. These rely on biological, chemical or heat treatment. The most common form of treatment is anaerobic digestion. Conventionally treated sludge has been subjected to defined treatment processes and standards that ensure at least 99% of pathogens have been destroyed.

What is Enhanced Treated Sludge?

Enhanced treatment, originally referred to as “Advanced Treatment”, is a term used to describe treatment processes which are capable of virtually eliminating any pathogens which may be present in the original sludge. Enhanced treated sludge will be free from Salmonella and will have been treated so as to ensure that 99.9999% pathogens have been destroyed (a 6 log reduction).
Your local Sewerage Operator will be able to provide further details of the treatment method used as this may affect where and when sludge can be applied, as well as the fertiliser and soil conditioning value.
