Scraper systems are suitable for a number of different uses, providing superior properties. The Finnchain scraper systems for rectangular tanks are used in several municipal water and wastewater treatment plants and in a number of industries, such as the paper, metal and food industries.

Surface and bottom scraper
The most common chain scraper system scrapes sludge from the bottom and skims surface of the tank. A cross collector can be installed in the sludge hopper for transferring the sludge to the removal system.

Other types are bottom scrapers, also suitable for lamella systems, surface scrapers, grit collectors and double layer tank scrapers.
