IFAT 2016 Germany: New Solutions for the Closed-Loop Wet Separation
As IFAT 2016 is just around the corner and hence, exhibitors are busy in preparing themselves best for the same. Doppstadt and its partner Siltbuster plan to display one of their latest innovations at the show. Here is more information on it.
Separating, washing, recovering: The name of the new all-rounder produced by the environmental technology enterprise Doppstadt and by its partner, the water treatment specialist Siltbuster, is Gritbuster. This washing and wet waste-recycling system puts an end to the time-consuming and expensive treatment of waste materials such as gully waste, road sweepings, sand or gravel. The secret: the Gritbuster uses water to separate undesirable materials in the input material and recovers it by its own closed-loop water treatment circuit. In this way, the Gritbuster systems work independently of large settlement ponds. They are not only suitable for stationary, but even for mobile applications and in particular for on-site use. Especially in case of wet waste streams the separation by size and density has been extremely difficult so far, the Gritbuster process on the other hand achieves an outstanding separating performance – while using water as a separating medium in an environmentally friendly, i. e. resource-saving way.
Gritbuster solutions are suitable for gravel washing and separating; street sweepings separation (up to 100 tons/day); filter sand washing; density-based sorting and separating of coarse and fine materials from construction and demolition waste.
The Gritbuster series includes two models with different feeding methods and capacities— The Gritbuster WT-100 can be loaded directly by street sweeping vehicles and achieves up to 15 tons/hour throughput and the Gritbuster WT-250 processes pre-dewatered or stored wastes, which are fed in by means of loader buckets from landfills. Its capacity amounts to up to 25 tons/hour.
The washed materials are separated by density so that a faultless result is achieved – for instance pure gravel, sand or sludge – without undesirable contaminants.
Both machines work on the same principle: In the whole installation clean water is used to wash and sort the waste streams. The cleaner the washing water, the higher the recycling product quality. Since water is not available in unlimited quantity, the Gritbuster recycles its separating medium: The integrated water treatment unit manufactured by Siltbuster ensures a self-contained circuit, which supplies the recycling process with clean water over and over again like a perpetual motion machine.
