<p>A waste water treatment process has a sand filter bed which is cleaned by back-flushing with air and water from time to time. The filter bed is sub-divided into segments which are back-flushed separately as required. A waste water treatment process has a sand filter bed which is cleaned by back-flushing with air and water from time to time. The filter bed is sub-divided into segments which are back-flushed separately as required. The filter bed is held in a filter basin with a pipe feeding both air and water, or a number of lances delivering air and water separately. Back-flushed water is then either returned to the previous filter bed or surrendered to a trap. The air pumped into the bed also oxygenates the reactor bed. The filter bed is a mixture of an inert substance, active carbon granules and an ion-exchange substance.</p> |
