“On behalf of Iona Management Services, I would like to thank Andidrain Ltd and your workforce for the planning and hard work that was done during the recent tank overhaul on our Anaerobic Digestion plant in Scotland. Andidrain were the perfect industrial services contractor to be selected for this project given we have worked together successfully on many previous projects throughout the UK. The close co-operation with myself and on site made it more achievable. I would fully recommend Andidrain for all AD tank clean out works & certainly look forward to working with you on future projects.”
The problem
The mixers in a customer’s Anaerobic Digester had stopped working due to the volume of solids that had built up in the tank and also the customer needed to repair several small holes in the tank. To repair the mixers and the holes in the tank the tank needed to be emptied and cleaned.
The solution
The material in the Anaerobic Digester was broken up using a fire hose connected to a wash out onsite and then vacuumed out of the tank using one of our DISAB Centurions. The wet material was then blown from the Disab into our mobile screening and dewatering plant which processed the material and deposited the dry material into a commercial bin at the rear of our mobile screening and dewatering plant. The customer removed the commercial bin using a forklift and tipped the dry material into their dry waste bays onsite for disposal. Our mobile screening and dewatering plant pumped the screened wastewater back into the customer’s process. Once the tank had been emptied it was given a final clean using the fire hose connected to a wash out.
