Exmouth WwTW was constructed several decades ago as a primary treatment plant, but BAFF (Biological Aerated Flooded Filter) process technology was introduced in the 1990s. Whilst the BAFF plant brought the works up to an acceptable performance level, over the following years operational problems started to arise giving South West Water cause for concern. ...
The second part, the soil filter body usually is planted with reed as the plants help to remove nutrients and optimize the soil structure for the filtering process. As the water percolates through the filter body nutrients and pollutants are removed. The filter body can work best, when it gets evenly charged with water from the ...
It is shown that a two-step process consisting of organics removal followed by biological aerated filters (biofilters) for nitrogen removal is a promising combination which allows a flexible and seasonally varied operation with a fast re-start of biological nitrification after shut-down periods. ...
