 The Nexus 3000 is one of
Evolution Aqua's most established filter systems incorporating the industry proven
Kaldnes Moving Bed coupled with the now recognized 'Answer' mechanical filter and the
new 'fines polisher with air backwash'. The Answer is a mechanical self cleaning
micron-screen which is extremely low maintenance.
The Nexus 3000 system is
designed for gravity fed configuration only.
How the Answer
works
The Answer sits in the central vortex chamber of the Nexus and prevents
all solids over 200 microns from entering the biological stage. The Answer is
robustly engineered out of stainless steel and a proven technology within the
industry. The pump that provides the power and cleaning action, draws filtered water
from inside the Answer. It is then pumped into a hollow rotor arm. At each end
of the arm are nozzles angled at 45 degrees. Water pumped through these nozzles
cause the arm to rotate. Water is forced out at high pressure against the inside of
the screen continuously, causing the water to backwash through the screen to the
outside. The result is that particles lodged on the outside, which are naturally
trying to get through, are forced away and eventually settle at the bottom of the central
chamber. Here, they can be drained to waste.
The Nexus 3000 system is a
complete unit and it includes the Nexus body, Answer self-cleaning micron screen, central
orifice plate, fines polisher with air backwash, air diverter valve, unionized ball
valves to waste, and Kaldnes media for the bio-reactor (fluidized
Kaldnes).
