Notice Information
Notice Title
Lithium Trace Testing
Notice Description
The Bioresource and Energy Services team require non-intrusive tank capacity and sediment assessments of Anaerobic Digesters using Lithium chloride as a trace element to comply with Environmental Permitting (England & Wales) Regulations 2016 implementing the Industrial Emissions Directive (IED) every 5 years, which takes an integrated approach to controlling pollution to air, water, and land from industrial activities. We require the supplier to develop methodology to determine the effective volume of an anaerobic digester over a short period of testing time. The effective volume should be calculated from the lithium concentration once it reaches a steady and consistent level. The calculation for effective volume should be based on the dose of lithium chloride added, the concentration of lithium, and the background concentration established before the test is initiated. The results of the data should establish the following, and be presented within a report: Mixing efficiency Hydraulic retention time (HRT) Short-circuiting or dead zones Sediment/grit accumulation The lithium chloride is to be dosed into each digester's feed line, or other suitable position. Prior to the dosing of lithium chloride, initial samples should be taken from each digester in order to establish the background lithium concentrations. Samples should be taken from designated sampling points, identified during a pre-test site visit.
