Siltbuster's Roadside Concrete Waste (RCW) recovery system is designed for the onsite disposal of waste concrete and alkaline waste wash water generated in the construction industry.

Typical applications

  • Washing out of concrete and grout pumps
  • Washing out of lorry-mounted concrete chutes
  • Washing out of crane and telehandler chutes and skips

Key features

  • Can be operated by either 12V battery or 110V electricity supply
  • Combines solid removal and pH adjustment with a single integrated unit
  • Easy to operate
  • Suitable for use in remote locations
  • Eliminates the need for the storage / use of strong mineral acids

The unit works by passing washed out wastewater into two large dewatering bags at the front of the RCW unit.

The dewatering bags act as a filter system to remove the solids from the water as it passes through the bags into the main chamber for pH adjustment.

The disposal of waste concrete, mortar and untreated alkaline waste water (pH 10 to 12) to ground contravenes most environmental management systems and can result in breaches in UK environmental legislation.

For this reason, the highly alkaline wastewater undergoes pH adjustment using carbon dioxide to lower the pH, which in turn causes the solids to precipitate.

The discharged water is then within required pH limits (pH 6.5 to 8.5), and can be discharged to sewer or water course.
