As each project is unique, all our Rotary Distributors for Trickling Filters are tailor-made to meet your exact specifications.
Flow variable sprinklers for trickling filters
While ensuring excellent distribution, the sprinkler flow can be variable, even with large variations, for seasonal needs (e.g. tourist season to be absorbed), daily needs (e.g. reduced night-time flow to be managed), or to cope with changing situations over the medium and long term.
These flow variations are managed internally in the sprinklers and automatically.
Power supply from above or below
All types of installation are possible, with one or more effluent inlets from above or below, or even both at the same time in the case of a "top-down" or "bottom-up" installation. sprinkler put down.
Visit sprinkler can be mounted or suspended on a flange.
In suspended versions, the beams are often supplied with the sprinkler to optimize the fixing of inlet pipes.
Sprinkler With or without motorization
Whether free-standing or suspended, the sprinklers can be motorized, allowing remote speed variation according to the Sk required. Even motorized sprinklers can revert to gravity mode in the event of electrical problems. This is an absolute guarantee for the operator.
Distribution uniform
It's vital to have the most uniform distribution possible. This is why each distribution opening has a unique position, and the calculation of all openings is spread over 2, 4 or 6 arms.
In the case of a variable flow rate with a ratio greater than or equal to 2 and a 4-arm sprinkler, and in order to achieve uniform distribution while maintaining good motricity, an initial flow rate will supply only 2 arms and a higher flow rate will supply all 4 arms; the changeover from 2 to 4 arm supply is made automatically by an adjustable threshold. This guarantees uniform distribution at all flow rates.
Design custom-built sprinkler for trickling filters
Each sprinkler is unique in its characteristics and specific features.
FB Procédés is fully conversant with the necessary hydraulic calculations, and thanks to its experience in the design and production of boiler assemblies, is able to respond to any situation that may arise, in both new-build and refurbishment projects.
