Crossrail cleans up

Crossrail’s Tunnelling and Underground Construction Academy has installed a Siltbuster plant to neutralise high pH water produced during sprayed concrete lessons at the facility.

Learning how to handle sprayed concrete is an integral part of the training the academy is delivering to 3,500 people during the Crossrail scheme but, the same as on the actual construction site, the equipment needs to be cleaned after use.

TUCA brought in the Siltbuster PMPU20 to treat the concrete wash water using its three stage process that uses a combination of carbon dioxide vapour and clarifying treatments to reduce the pH of the water.
