Treatment and disposal of contaminated materials such as soils, wastewater, spent activated carbon and spent pot liner present environmental, safety and economic challenges to industry. HRL assists clients in testing their contaminated materials and evaluating treatment options.
HRL's range of services relating to contaminated materials are applied in industry areas including soil remediation, activation carbon regeneration, landfill disposal and aluminium smelting (spent pot liner).
A major area of capability relates to construction and operation of pilot scale equipment to investigate and demonstrate the performance of commercial or novel thermal treatment processes. As an example, we simulate thermal desorption processes in a small rotary kiln to determine the parameters, such as temperature and residence time, required for effective removal of organic contaminants. The extent of removal is determined based on analysis of the contaminated material before and after treatment.
Specific services which are applied to testing and remediation of contaminated materials include:
Extensive experience in evaluation of upgrading and utilisation options for coal and othermaterials. Experience includes material characterization, practical research and demonstration,techno-economic assessments, and detailed feasibility studies. Processes investigated include gasification, dewatering, drying, agglomeration, pyrolysis and activated carbon production. Read more
