Advantages & Disadvantages of Comminutors

Advantages

• Elimination of extra steps and problems involved in the excavation of the disposals of screening (screened material)
• Often difficult to dispose highly polluted screenings - In USA if buried, 6 inches of cover material should be used
• Highly suitable for small treatment plants. e.g. : mountain or beach resorts.

Disadvantages

• Frequent maintenance of cutting tools ( delicate equipment)
• Risk accumulation of comminuted materials (textiles, vegetable fibers) eventual clogging of pumps and piping.
• These materials to form floating scum in anaerobic digestion
• Problems in trickling filter (clogging of distribution pipe holes)   mainly used in activated sludge process.
