Sustainable and cost-efficient solutions for your sludge

Sludge originating from your production process or water purification system may not always be the first thing on your mind, but it can seriously disrupt your primary process, resulting in high costs.  To avoid this, a customised solution is needed.

Full service provider

You can subcontract all aspects of your sludge dewatering to Indaver Impex.  Indaver Impex is the no. 1 expert, offering a total solution for your sludge treatment.  Your sludge is dewatered on a fully continuous or project basis, using permanent systems or mobile units.  By dewatering the sludge on your site, we substantially reduce the volume to be transported away.  This saves you transport and treatment costs.Our size, capacity and in-house expertise ensure that we can step in rapidly.

Innovative technology, dedicated staff and the correct chemical conditioning guarantee optimal sludge dewatering. 

Thorough sample analysis in our own laboratory

In order to offer you a customised solution, we map out your process thoroughly in advance, including sample-taking.  In the Impex laboratory, we subject your sludge samples to a comprehensive test programme in order to determine the best formula and dewatering technique.  To improve the dewatering efficiency, additives such as ‘IMPEXFLOC’, from our own line of flocculants, may be used.  We translate test results for you into a specific, practical solution, after which we can get to work on your site.

European growth

Impex provides its services throughout Europe and is the market leader in Benelux.  With over 25 years’ experience, Impex has built up a large portfolio of satisfied customers.    We have rolled out successful sludge dewatering projects for a wide variety of industries such as the chemicals, petrochemicals, pharmaceuticals, steel, construction and foodstuffs industries and water boards.  And we always do so with the closest attention to safety and the environment. 

In the Netherlands, we designed and built a sludge dewatering facility at Tata Steel in IJmuiden that treats sludge originating from a gas washing process.  Tata Steel re-uses the sludge cake in its production process.

For a company in the food industry, we designed and built a system on site that removes the sulphur from the sludge cake so that the cake can be re-used by the fertiliser industry.

Indaver Impex works in this field for:

  • district water boards and drinking water companies
  • industries such as the chemicals, petrochemicals, pharmaceuticals, food, construction, steel and waste treatment industries
