The Seeker for this Challenge is looking for a method to separate a slurry composed of water, sand and fine particles into its different components and to control the particles partition between them. The method needs to be cost-effective for use in applications at very large scales. 

This Challenge requires only a written proposal.


Slurries – essentially, a fluid mixture of a liquid and fine particles – are commonly found in various industries. Cement, construction, bulk and fine chemicals, waste water, and livestock, are just a few examples of industrial applications that deal with slurries. The Seeker for this Challenge is inviting all these experts around the world to apply their expertise and creativity to solve an exciting separation challenge for the dredging industry. 

Large amounts of slurry (300,000 m3 to 3,000,000 m3 slurry per week for 1 unit) are generated as the result of one operation and the Seeker needs to relatively quickly separate the slurry into its different components (water, sand, and fines (silt)), in a controlled manner. Hence, the Seeker is looking for a cost-effective method to perform this separation at a very large scale and under challenging conditions, which are described in the Detailed Description of the Challenge. 

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on December 07, 2015. Late submissions may not be considered.

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. 

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution.  However, the Seeker will be willing to consider a licensing agreement for a partial award if exclusive IP cannot be transferred by the Solver.


What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical IP Transfer Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-IP Transfer Challenge, meaning that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. By contrast, Theoretical-Licensing means that the Seeker is requesting non-exclusive rights to use the winning solution. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
