Group has a diverse set of science and engineering skills that enable
us to complete projects in many fields or disciplines. From niche
one-on-one consultancies or analytical services to collaborative
multi-disciplinary and multi-stakeholder research programmes. See below
for some examples.
Bioreactor for removal of nitrates in agricultural water
Verum Group is putting their experience in passive water
treatment systems toward a new target, the removal of nitrate from
This research uses a system to remove nitrate from tile drain water on a
participating farm in the Waikirikiri-Selwyn River catchment. We are
trialling two bioreactor systems, a more traditional woodchip
bioreactor, and a “enhanced passive treatment system”. By providing
additional nutrients into the reactor, we create a favourable
environment for the bacteria to flourish and reduce the nitrate to
nitrogen. Regular monitoring will be completed to quantify the
effectiveness of this novel water treatment system.
