Rotary Distributors for Trickling Filters

For more than 30 years, FB PROCÉDÉS has been designing, manufacturing and installing sprinklers for bacterial beds, based on the fundamental values that have made our reputation: simplicity, efficiency and reliability.

Since each installation is unique, our sprinklers are designed and dimensioned to measure — based on the diameter of the bed, the required flow rate, and the hydraulic and structural constraints — in order to guarantee a homogeneous distribution of water over the bed, and optimal operation, whether in new projects or renovations.

While ensuring excellent distribution, the flow of the sprinkler can be variable, including in significant variations for seasonal needs (for example, tourist season to be absorbed), daily (reduced nighttime flow to manage), or to cope with evolving situations in the medium and long term.

These flow variations are managed internally in the sprinklers and automatically.

All cases of implantation are possible with one or more effluents entering from above or below, or even both at the same time in the case of a sprinkler installed.

The joint sprinkler for a waiting flange can be either placed on the ground or suspended.

In suspended versions, the bracing is often provided with the sprinkler, thus optimizing the fixing of the inlet pipes.

Whether mounted or suspended, the sprinklers can be motorized, allowing for a speed variation at a distance depending on the target area. Even motorized sprinklers can revert to a gravity mode configuration in the event of electrical problems. This is an absolute guarantee for the operator.

It is essential to have the distribution as uniform as possible. Therefore, each distribution opening has a unique position, and the calculation of all the openings is thus distributed over 2, 4, or 6 arms.

In the case of a variable flow with a ratio greater than or equal to 2 and a 4-arm sprinkler, and in order to achieve uniform distribution while maintaining good mobility, a first flow will supply only 2 arms and a higher flow will supply the 4 arms; the transition from a 2-arm feed to a 4-arm feed is performed automatically by a adjustable threshold. This guarantees uniform distribution at all flow rates.
