Esmil - Picket Scraper

The Esmil picket scraper is a highly effective solution for thickening different types of sludge and suspensions. Designed for use in radial thickeners, it optimizes the thickening process while significantly cutting costs associated with sludge transportation, stabilization, and dewatering.

• Efficient sludge collection from the bottom of sedimentation tanks for improved treatment performance
• High processing capacity ensures reliable and consistent operation
• Robust, corrosion-resistant construction for long-term durability
• Low operating costs due to energy-efficient design and minimal maintenance requirements
• Customizable sizes and configurations to meet specific plant needs

Application of ESMIL Picket Scrapers:

• Wastewater treatment plants
• Industrial processing sites
• Water purification plants

Benefits of ESMIL Picket Scrapers:

• Eliminates the need for costly bridge drive units or track cleaners, reducing overall maintenance expenses.
• No requirement for slip ring installation.
• Constructed from stainless steel and aluminum for exceptional corrosion resistance and high durability under heavy loads.
• Diametral bridge design allows easy visual inspection of the sedimentation tank’s operation.
• Safe personnel movement ensured by an anti-slip “lentil” walkway surface and protective lower barriers on handrails.
• Integrated bridge lighting enhances safety during evening and nighttime operations.
• Equipped with a maintenance-free radial thrust bearing on the thickener’s central drive, capable of supporting heavy loads.
• Features a bearing lubrication system that enables servicing directly from the bridge without stopping or dismantling the drive unit.
• Scraper blades include a sturdy metal frame with a replaceable rubber strip for efficient sedimentation tank cleaning, allowing cost-effective replacement.
• Picket scraper design in the gravity thickener improves sludge thickening by effectively draining excess water from all sludge layers.
• Control cabinet with frequency converters enables precise adjustment of scraper speed, with Siemens controllers ensuring process management and overload protection. The cabinet can be mounted on the bridge or installed indoors near the scraper.
• Delivered in large modular sections for fast and easy assembly, reducing labor costs, installation time, and reliance on expensive specialized equipment.
