Our specialized services include the removal and processing of sludge from oil refineries and industrial plant wastes. Sludges processed by Handex include:
We offer a broad range of experience in handling tank bottoms, which includes sludge removal, processing, transportation and disposal of waste materials.
We start by understanding the problem and coming up with an appropriate solution. Services begin with preliminary bench scale evaluation of a representative sample to determine the most appropriate and cost- effective dewatering technology content.
In most cases, the processing of tank bottoms through mechanical separation of the liquid and solid phases is the most cost-effective approach when compared to the costs associated with pumping and trucking off-site for disposal.
Processing and volume reduction is accomplished by plate and frame filter presses, centrifuges, belt filter-presses and geomembranes. Additional equipment can be added to the process treatment train to remove low-level contaminants in the liquid phase prior to discharge. Solid filter cake is loaded into containers for shipment and disposal or recycling, which can be arranged by either us or the client.
We utilize equipment that complies with Benzene NESHAPS, and secondary treatment of the process effluent to meet refinery requirements.
All of our personnel have extensive training in Health and Safety, including Confined Space Entry and OSHA 40-Hour HAZWOPER and annual OSHA 8-hour refreshers. This includes:
