Brochure plastic scrapers

Product catalog summary

Overview: The document discusses the use of non-metallic scrapers, specifically MITA Biorulli chain scrapers, in biological wastewater treatment systems. These systems typically involve three phases: primary settling, biological treatment, and secondary clarification. The scrapers are designed for rectangular tanks and offer advantages such as modularity, compactness, and space optimization.

Specifications: The scrapers are constructed from reinforced polyester resin with UV protection, poly-acetate self-blocking pins, reinforced Nylon drive chain links, and AISI 304 stainless steel components. They feature high resistance fiberglass drive shafts and scraper bars, Nylon-6 supports, and polyethylene wear strips.

Operating Principle: The scrapers function as surface skimmers to remove floating substances. Their non-metallic construction prevents corrosion, reducing maintenance needs and extending equipment life.

Applications: These scrapers are suitable for primary and secondary settling tanks, tertiary clarifiers, and dissolved air flotation systems in rectangular tanks. They are intended for new installations and the refurbishment of existing plants.

Key Characteristics: The scrapers are lightweight, self-lubricating, and require minimal energy. They are easy to assemble and maintenance-free due to their corrosion-resistant materials. Scraper blades are available in "Standard" and "Ultra" versions for different tank widths.

Technical Data: The document provides detailed technical specifications for components such as stub shafts, chains, wall guides, headshaft assemblies, drive sprocket wheels, and clarifier flights, emphasizing the use of materials like fiberglass and Nylon-6.
