Although the use of filter bags would be very versatile, regardless of the type of wastewater treatment, this often goes unnoticed. This may also be due to the fact that there is hardly any specialist literature on this simple and inexpensive process.
The effectiveness of filter bags in terms of throughput and drying results that can be achieved is often underestimated. However, because of the extremely low investment and operating costs and the simple handling, this process should definitely be considered, especially for smaller quantities of sludge.
This cost-effective type of sludge dewatering is used wherever small amounts of sludge accumulate and a high dry matter content is required. So for sewage treatment plants between 5 - 1,000 PE.
