Complete system for conveying sludge
Sludge from sewage works is a residual product which is fairly unpleasant to handle. Spreading it on the fields as manure may inconvenience the surroundings and attempts at incinerating it at combined heat and power stations were unsuccessful because of its water content.
The first system has now been set up where sludge from wastewater via a process of steam desiccation and pyrolysis is transformed into so-called bio coke. It is a valuable manure which is easy to handle. The process removes the water content from the sludge and eliminates environmentally harmful substances such as microplastic and medicine residues.
We have supplied an integral solution for conveying sludge in the same system where it undergoes pyrolysis treatment. Together with Aquagreen, supplier of the total solution, we have designed the conveyor solution. BEMA has been in charge of producing the full screw conveyor solution, the final assembly and test run of all screws in our test stand.
The whole solution has been produced in stainless steel for max. wearability and resistance to the powerful substances contained in sludge.
Screw conveyor for the food industry
To a customer in the food industry, we have supplied a complete polished screw conveyor integrated into their system and used to convey raw materials. It should be noted that the food industry requires particularly high standards of their equipment. In this case, extremely smooth surfaces and very precise tolerances are a requirement to ensure correct function.
The screw conveyor is Ø 75 mm and made in stainless steel 1.4301. It is all-welded and subsequently polished to ensure total smoothness and avoid any residues of raw materials being left behind.
BEMA has carried out all processes from design to production and finishing and is therefore able to guarantee the final result.
