Sludge Drying and Incineration Systems
Drying and incineration plants process materials from different sources, such as raw, biological, mixed, or digested sludges. Therefore, the pumps used must be resistant to variable and challenging process conditions.
SEEPEX offers integrated sludge conveying solutions developed specifically for each application.
Application examples:
BTHE, BTE, BTI series: Transfer of dewatered sludge to silos
BTES, BTEI series: Conveying sludge from silos to drying or incineration systems
Wastewater and Sludge Treatment
SEEPEX’s progressive cavity pumps and grinders offer efficient and reliable conveying solutions in all stages of wastewater and sludge treatment. In this way, the sludge is optimally fed to thickening and dewatering systems and prepared for drying, incineration, thermal hydrolysis, or biogas production.
Areas of use:
BN series: Transfer of primary and secondary sludge to thickeners
BN, BTQ, BT series: Conveying thickened sludge to digesters
T series: Preparing dewatered sludge for processing by re-mixing
M series grinders: Reducing solid and fibrous particles
Sludge Mixing Systems
SEEPEX pumps efficiently mix sludges from different sources, regardless of the dry matter content. In this way, the desired density and homogeneity are achieved throughout the process.
Application examples:
BTHE series: Transfer of sludges containing 18–35% dry matter to temporary storage
BTE and BTES series: Making dewatered sludge suitable for processing by re-mixing
SCT series: Pumping liquid sludge to mixing systems
CO control systems: Monitoring processes such as level, pressure, and dry running protection
Advanced Digestion
Anaerobic digestion is an effective method for breaking down organic matter for biogas production. Advanced digestion processes supported by thermal hydrolysis increase sludge decomposition efficiency, maximize biogas production, improve sterilization, and reduce sludge volume.
SEEPEX offers specially designed pump systems for these high process requirements.
Application examples:
BTHE series: Feeding of thermal hydrolysis systems
BN series: Transfer of hot sludge to reactors and digesters
BTHE series: Reliable conveying in “Class A sludge” applications
Chemical Additive Metering
Organic and inorganic additives used in wastewater treatment increase the efficiency of biological and mechanical processes. Accurate metering is critical for process safety and system stability in these applications.
Application examples:
MD/MDF series: Metering of flocculant and polymer-based additives
BN/MD series: Disinfection applications with hypochlorite
BN series: Precise metering of chemicals such as lime milk for pH balance
