Densadeg XRC™
extreme-rate ballasted clarifier
Extreme-rate treatment
The DensadegXRC™ is a high-rate settling clarifier process combining solids contact, ballast addition and solids recirculation to provide
enhanced, high-rate settling of solids. The process consists of:
optimized mixing energy and detention time. The result is a floc
which settles at extremely high rates.
4 SETTLING & CLARIFICATION ZONE: Flocculated solids enter
1 RAPID MIX / COAGULATION STAGE: Raw water flows into the
the settling zone, over a submerged weir wall, where dense,
suspended matter settles to the bottom of the clarifier. Clarified
water is displaced upward from the downward moving slurry,
through inclined plate settlers. The plate modules act as a
polishing step for lighter, low density solids.
rapid (flash) mix zone where a coagulant is added. Coagulation
is the destabilization of colloidal particles, which facilitates their
aggregation and is achieved by the injection of a coagulant such
as alum or ferric chloride.
2 FLOCCULATION ZONE: Coagulated water then flows to the
5 HYDROCYCLONE AND BALLAST RECOVERY: Settled sludge is
flocculation zone where, with a lower energy vertical turbine
mixer, a continuous ballast media recirculation feed and a low
dose of a flocculating agent (polymer) are added to begin the
process of agglomerating the coagulated water into floc
particles.
continuously recycled via a recirculation pump to the hydrocyclone
where the ballast media is separated from the waste stream.
Ballast is returned to the flocculation zone and the waste stream
is sent to sludge handling.
3 MATURATION ZONE: Flocculated particles are then developed and
grown into large, very dense mature particles. This is achieved with
6 EFFLUENT COLLECTION: Uniform collection of clarified water
is accomplished in effluent launders above the settling plate
assembly.
