Iron removal

The paper describes the preliminary researches on the influence of the ultrasounds of diversified intensity (22 and 24 kHz) on the content iron compounds in water. For the researches, variable operational parameters were used, such as: the vibration amplitude and the exposure time (1–5 min). The sub

Pilot scale trickling filters were constructed and tested in order to study biological removal of ammonia, iron and manganese from potable water. The effect of the size of the support material on nitrification performance was studied extensively. The mean size of the gravel and hence, the specific s
