non metallic chain plastic scraper Non-Metallic Sludge Scrapers for Corrosive Media | 18-Yr Expertise

A non-metallic chain plastic scraper system, often referred to as a chain and flight collector, utilizes a series of plastic flights connected by engineered plastic chains or cables to move sludge along the bottom of a rectangular or circular clarifier. This system represents a significant advancement over traditional metallic chain systems. The replacement of steel chains with corrosion-proof plastic versions eliminates the single greatest point of failure in these collectors. Metal chains are highly susceptible to corrosion, which leads to stretching, binding, and eventual breakage, causing extended downtime and expensive repairs. Plastic chains are impervious to this degradation, ensuring continuous, reliable operation with minimal maintenance. The plastic flights are also lighter than their steel counterparts, reducing the overall weight that the chain must pull and thus lowering the energy consumption of the drive system. Furthermore, the smooth, low-friction surface of the plastic reduces wear on the guide channels and sprockets. This entire system is designed for durability and efficiency in the harsh, corrosive environment of wastewater treatment, providing a robust solution for long, rectangular basins where other scraper types are not applicable. We specialize in the design and supply of complete non-metallic chain and flight systems, offering a permanent solution to the chronic maintenance problems associated with older metal designs.
