FILTRATEC extends its sludge dewatering capacities at Chemelot Industrial Park

By delivering a full range of sludge dewatering services, FILTRATEC helps to promote cost-effective and sustainable waste management concepts and solutions in a whole range of industries. Many customers have been making the most of this specialist provider’s expertise for decades – including the Chemelot Industrial Park, one of the five largest business parks in the Netherlands dedicated to the chemical industry. For over 25 years now, FILTRATEC has been developing and implementing customerspecific solutions at the park. These include both operational services as well as providing the filtration equipment needed.

A further stationary membrane filter press is currently being built for Chemelot to ensure there is sufficient capacity for the growing demand. Once it is up and running, this large-scale press, which will be operated by FILTRATEC, will be able to process up to 600 tonnes of ‘thin’ industrial sludge each day. Total chamber volume will have increased to 12.4 cubic metres once it and the facility already being used at the site are both in operation. This is almost three times the capacity available at the beginning of the collaboration. Over the years, the treatment capabilities have gradually been extended – a reflection of the way the industrial park has expanded during this period. It also clearly shows how long-standing cooperation work can help ensure that there are always sufficient capacities and reliable services available in the field of sludge dewatering as well.

Established procedure

Sludge dewatering has established itself as a useful alternative to liquid disposal systems. The very most can be made of the cost-effective and environmental benefits of sludge dewatering when both the services and the equipment have been perfectly adapted to meet the requirements of a project. FILTRATEC is currently setting up a future-oriented solution at the Chemelot Industrial Park in the Netherlands – clearly showing just what is possible in this field of business.

Focusing on customer requirements

FILTRATEC dewaters all of the industrial sludge produced at the park for Sitech. To be able to do this, it currently deploys a stationary membrane filter press that is capable of handling large volumes of material. The facility, which was set up in 2012 and built by FILTRATEC specifically for Chemelot, is operated 24/7, 365 days a year. Its bespoke design combines both the company’s many years’ experience of filtration services and its findings from carrying out extensive trials. By adapting the facility to the exact requirements of the industrial park, it is able to achieve excellent solid/liquid separation results – i.e. a filter cake with a high dry residue content and a solids-free filtrate. This means – for both Sitech and Chemelot – that the amount of solids left over which have to be sent for disposal is kept to an absolute minimum.

FILTRATEC specialises in sludge dewatering, solids/ liquid separation, product filtration and sludge and wastewater treatment

New large-scale press will double capacity

Having performed such successful work, FILTRATEC has now been given the task of extending its sludge dewatering activities at the park. Besides expanding the scope of services, this project also centres on a second filter press, which will also be designed as a membrane unit. Both presses will be used side by side in the future – and will be located in the same area, as the existing plant was designed so that a second system could be added should it be needed.

Using filtration to reduce the volume of material cuts both waste management and transport costs

The sludge dewatering capacities available to the industrial park will have been almost doubled once this new large-scale press is up and running. The size and scale of the new facility take future growth into account. Having said that, though, the extra capacity that is expected to be needed in the future will be useful right from the start. It means the units will be able to cope with any unexpected volumes caused by a sudden increase in sludge production. In the past, mobile units have had to be brought in to treat this additional material. What’s more, by doubling the capacity of the units, the company will be able to provide an even more reliable service.

“The industrial-scale sludge dewatering system at Chemelot Industrial Park is an excellent example of how collaboration work can help develop and move projects forward so they are fit for the future.”

Gerd Brückerhoff, Managing Director of FILTRATEC Mobile Schlammentwässerung GmbH

Optimum equipment design

With over 40 years’ experience, FILTRATEC has in-depth expertise in both developing and building practical mobile and stationary filtration units. The equipment, which has often been specifically developed to meet individual customer requirements, is part of the service package and remains the property of FILTRATEC. This means, of course, that its industrial and municipal customers do not have the financial burden of having to invest in their own equipment, Furthermore, it increases transparency and makes it easier for their clients to plan their costs.

The units, designed by the company’s own engineering department, are built, connected and assembled at FILTRATEC’s head office in Voerde, a town in the Lower Rhine region

FILTRATEC will operate both filtration units at the Chemelot Industrial Park for ten years via its Dutch subsidiary FILTRATEC B.V. FILTRATEC has been operating in the Netherlands for around 30 years now. The country is one of the most important foreign markets for this filtration specialist, which delivers its services across the whole of Europe. Besides using filter presses, the firm’s sludge dewatering division also deploys decanters, including gas-tight three-phase decanters for separating combustible and/or harmful substances. In many cases, FILTRATEC is also involved in manufacturing processes. For example, in the field of metal production where this specialist is able to deliver speciality product filtration solutions so that even aggressive and acidic substances can be filtered.
