Municipal and Industrial wastewater treatment is subject to strict environmental legislation which are regularly reviewed and updated on a global level. In order to meet ensure ongoing compliance our customers are always looking for innovative solutions to their challenges that can improve up-time, minimize downtime and play a big role in energy and chemical reduction, whilst at the same time maximize the plant’s output.
SEEPEX supports the purification and clarification of wastewater with state-of-the-art wastewater pump technology. These pumps can be used in sludge dewatering, sludge drying and incineration, sludge treatment and mixing, or optimized digestion processes. Thus, they can contribute to much more efficient, cost-reduced and simplified processes.
SEEPEX wastewater pumps are particularly economical, as they convey highly dewatered cake and sludges with virtually no restrictions on viscosities or abrasive materials. Slurries with dry matter contents of up to 45% are transported effortlessly.
Our standard wastewater pumps are robust and can be used to reliably pump primary sludges or thickened sludges. For discharge from thickeners or silos, our hopper wastewater pumps (optionally with screws and blades) are suitable for conveying dry masses onward without disruptive bridging.
With intelligent maintenance concepts, we help our customers in the wastewater industry to carry out their activities quickly and easily, thus saving time and operating costs in the long term.
After sludge treatment, sludge volume is reduced by various dewatering methods with the end result being a product with a dry solids content of 18 – 45 %. The physical characteristics of the sludge can vary significantly, it is therefore essential that the dewatered sludge handling system selected has the flexibility to handle these demands.
SEEPEX specializes in handling highly-viscous, non-flowable products and finding the most economical solution for the most challenging applications.
Some sample applications:
Sludge drying and incineration centers process sludge from external sources. Depending on the source, the imported sludge can be raw, biological, mixed or digested. As a result, the pumping systems are faced with arduous and diverse requirements.
SEEPEX offers sludge cake pumping systems that are designed to integrate perfectly with each specific application.
Some sample applications:
SEEPEX progressive cavity pumps and macerators offer the best conveying solutions in all areas of wastewater disposal and sludge treatment. With SEEPEX technology, the sludge is efficiently pumped into thickening and dewatering machines, optimally preparing it for further processing such as drying, incineration, thermal hydrolysis or biogas generation.
Some sample applications:
SEEPEX pumps convey and mix sludge from different sources, regardless of their initial dry solids content. Our pump’s mixing and dosing abilities provide further process options for the sludge and set the required dry solids content.
Some sample applications:
Anaerobic digestion is a proven process for breaking down organic substances and generating biogas. Advanced digestion using thermal hydrolysis intensifies sludge digestion by significantly improving decomposition. It generates higher biogas generation, a higher level of sterilization and the volume of sludge produced after dewatering is reduced; However, the thermal hydrolysis process changes the sludge properties, imposing significant requirements on the pump and materials.
SEEPEX develops tailor-made systems to meet the high demands in this type of process technology.
Some sample applications:
Organic and inorganic additives are added to bring about various biological and mechanical processes in wastewater treatment. Precise metering and high safety levels are crucial, particularly when working with viscous, corrosive and abrasive additives.
Some sample applications:
SEEPEX Progressive Cavity Wastewater Pumps are highly reliable assets for all process steps within Wastewater Treatment Works.
"In the long term, we are even questioning if we need "duty stand-by pumps". That's how satisfied we are with the maintainability of the SEEPEX SCT wastewater pump."
