Device and method of recovering sticky particulate materials such as algae
Abstract
Abstract Sticky particles (algae) are recovered from environmental liquid by being passed through a precoat on a screen, the particles being entrapped in the precoat. Dewatering and drying follow and the precoat with the entrapped particles is removed from the screen for subsequent use. The device for carrying out the method includes a screen moving in a set path. A coating unit supplies a precoat to the advancing screen. A depositing unit supplies particles in their environmental liquid to the precoat. Dewaterers and driers remove much of the liquid. The remaining, particle-precoat combination is removed from the screen preferably by a sonic whistle, and is discharged from the machine. A washer cleans the screen for reuse when necessary.
