WATER treatment specialist Siltbuster has created a new system to dispose of sweeper waste on construction sites.
The Sweeper Tip works by separating solid waste from the water, which is then treated before being discharged to a sewer.
Siltbuster said this results in time and cost savings as it removes the need for sweepers to make multiple journeys offsite to be emptied.
The firm explained that, using a three-stage process, the waste is tipped directly from the sweeper into a specially adapted hooklift unit, where the coarse solids are separated out of suspension and the supernatant water is then pumped off for further treatment.
The water recovered from the first hooklift unit is chemically treated to encourage the finer solids to form larger, more easily separated particles.
These are separated by pumping the water at low pressure through one of Siltbuster’s geotextile dewatering bags, trapping the remaining solids inside.
The treated water produced is said to be clean enough to be discharged to the sewer without further treatment, while the retained solids further drain prior to disposal.
Dr Richard Coulton, CEO at Siltbuster said, “We pride ourselves on creating bespoke systems that are designed with a specific purpose in mind.
“The mobile Siltbuster Sweeper Tip not only provides an effective removal of all waste materials, it also reduces the number of lorry movements to and from the licenced facilities, saving both time and money.
“By using the Siltbuster sweeper system, our clients are also able to monitor and measure the exact amount of waste being collected and disposed of. This information is crucial for future audits.”
