Clariant launches high-performance sediment dewatering system

Posted: Thursday 9th June 2016

INVOQUE boosts the dewatering process, reduces energy consumption, improves quality of filtered water & creates optimally conditioned sediments.

Clariant has launchedINVOQUE, a unique single sediment dewatering package with substantial ecological benefits and designed to improve user productivity and profitability.

INVOQUE addresses the need in the mining, civil engineering and coastal, reservoir and riverine dredging sectors for higher performance, sustainable products which reduce or eliminate the environmental impact of sediments and reduce process costs. It is the only commercially-available high performance mineral-based technology on the market. In addition, INVOQUE stands out for its capability to make the dewatering process more efficient and cost-effective compared to other technologies at the same time as providing environmental benefits.

Unlike conventional conditioning / flocculating agents, INVOQUE's modified mineral-based additives provide multiple modes of action in a single process. It destabilizes, flocculates, precipitates and releases water at the same time as naturally mopping up a number of trace contaminants from the water phase. The high-performing, sustainable and innovative process helps customers to reduce the total cost of ownership of their dewatering system and gain value from their sediments. Compared to other dewatering systems, INVOQUE delivers:

Gerry Southwood, Head of Business Line Sediment Management at Clariant Business Unit Functional Minerals, comments: "Worldwide close to 800 million tons of sediments require costly dewatering and decontamination. Clariant is therefore proud to present the market with this new solution for more sustainable sediment dewatering. With INVOQUE we are already seeing that customers achieve a high level of technical performance in the dewatering step, with operational, ecological and cost benefits on top. INVOQUE therefore presents a true step forward that will have exciting appeal globally."
