The decolloid is used as a fuse, the suspended solids are trapped there, thus protecting the elements located downstream of the die (sand filter ...). It is operational after filling with pozzolan (independent supply - see sheet 6095).
The horizontal "tee" shaped inlet provides a jet breeze function. The effluent arrives in the upper part of the filtering mass, in order to facilitate the maintenance operations in the event of clogging (this principle limits the actions of withdrawal of the filter material at each inspection and emptying).
All our models of PRV decolloiders are equipped with a technical floor, a unclogging column and a tilting lid allowing maximum accessibility inside the tank.
The decolloid should be filled with pozzolan, a mineral, heavy filter material (regular particle size between 20 and 40 mm).
Reminder: The pozzolan must be ordered separately and it is delivered in bags of 40kg (about 59 liters) reference PZ01.
