Silts can be dried by placing them in drying beds, in lagoons or lagoonation fields or by mechanical processes such as filter presses, belt presses or centrifuges.

All of the mechanical methods need flocculants or polymers to be added to help them work effectively.

Other methods include drainage through geomembranes made into geobags where the silt is pumped into the membrane and the water drains away through the small holes leaving a dry silt.

The company’s expertise has been developed through the ever-increasing need to remove and dispose of contaminated sediments in rivers, canals, lakes, lagoons and harbours.

Working closely with other group companies Land & Water Remediation has aninnovative approach to the application of specialist knowledge and plant to offer cost effective solutions to clients.
