HUBER Screenings Treatment Systems - Optimal systems for any
application - High dewatering efficiency - Maximum washout
degree - Reduced disposal costs The first step in wastewater
treatment is normally the removal of solids from the wastewater
flow by means of screens. The removed screenings contain
household waste, faecal matter, toilet paper and mineral solids.
The screenings volume depends, not only on the separation size
of the screen, but also on the type of sewer system. The solids
content of municipal screenings varies between 10 % and 25 %,
depending on the type of screen. Approximately 90 % of the
solids are volatile (organic). Due to their very high water
content, their heterogenous composition and unaesthetic
appearance screenings must be treated before 2000 they can be
disposed of. The best method of screenings treatment is washing
and compaction with a wash press. Fecal matter and other organic
materials are removed and returned into the wastewater flow. As
a result, a good wash press increases
