Water Treatment Solution Keeps an Industrial Plant Shutdown On-Track

Industry

Proactive cleaning of plant internals ensured optimal performance during regular operations.

A UK waste treatment plant planned a scheduled shutdown to carry out critical maintenance work.

During the shutdown, the Cheshire-based industrial plant organised proactive cleaning of plant internals.

Challenge

Intensive jet washing during the cleaning process allowed the plant to effectively remove built-up residue from internal surfaces but also produced a significant amount of contaminated water. As the onsite wastewater treatment plant was taken offline, the cleaning process needed to be handled externally and carefully managed.

Solution

RVT Group installed a full water treatment solution, designed to neutralise pH whilst separating silt and suspended solids from the water.

The set up involved pumping contaminated water from the catchment area to an EnviroHub TT10 Treatment Tank where pH was measured. A TU02 Dosing Skid received these measurements and automatically delivered the correct dosage of caustic and coagulant to the tank.

Once the pH had been neutralised, the treated water flowed into the HL50 Lamella Plate Settlement Tank. Here, solid separation occurred and effluent which remained was ready for discharge inline with environmental regulation.
