Iron / manganese removal - Lenntech

Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well: Oxidation can be carried out by various chemicals like chlorine, ozone but is mostly done by compressed air. Complex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove.

Filtration - MRWA

Early slow sand filters typically have filter rates of 0.05 gpm/ft2 of surface area and require large filter areas. The top several inches of the sand has to be removed regularly--usually by hand--due to the mass of growing material ‘schmutzdecke’ that collects in the filter. Sand removed is usually washed and returned to the filter. These filters are still in use in some small plants ...

2017-01-10  Slow sand filtration systems have been used for many years; the first systems operated in London in the 19 th century. However, slow sand filtration systems require large areas of land to operate, because the flow rate of the water is between 0.1 and 0.3 metre per hour. Due to the land area that is required and the down-time for cleaning, rapid ...
