Panton McLeod cleans ozone-treatment tanks

Panton McLeod was hired to drain down and clean three ozone-treatment tanks at the Campion Hills Water Treatment Works, in order to prepare them for a full repair and modification project.

The company also removed around six tonnes of freshwater zebra mussel shells from two of the tanks with industrial vacuum pumps and by hand.

Chris Faulks, supervisor, Panton McLeod, said: 'We brought in specialist suction equipment so the mussel shells could be removed to a tanker, but our guys also had to get in the tanks and remove some of the shells the old fashioned way by hand and with buckets.

Panton McLeod specialises in the cleaning of drinking-water structures, including treatment works, service reservoirs and slow sand filters.

The firm has also pioneered the use of underwater robots, which are used to inspect and clean structures used to store potable drinking water across the UK.

The machines are remotely operated and fitted with camera and lighting equipment, which allows staff controlling the ROVs to assess the interior of the tanks.
