Hi Andrea,
What you mean for "standard solution"?

IMO, removing the sliver polygons is not an easy operation!
There are several alternatives to do that!

i.e.:
in GRASS you could use module v.clean;
in PostGIS you could use filter "smaller than a given area" in WHERE
condition;
again in PostGIS: [1]


So, there is no standard procedure for the solution to removing slivers
polygon!

Also this could be interesting [2]! Thinking of a tool for QGIS!
