why choose us
Founded in 2017 after almost 20 years experience developing and designing best in class ion exchange processes for nitrate and hexavalent chromium removal, Agua DB realised that current ion exchange processes used in the water industry were neither affordable nor sustainable. This had lead to a dysfunctional supply chain, with insufficient business to support a dedicated equipment supplier. The technology needed to change from a linear process, producing a waste, to a circular one, recovering nutrients and other valuable materials for re-use.
NTPlus offers a sustainable response to the world’s nitrate problem.

our history - nitrate removal
> Strong base anion resins were the first on the scene, but these showed nitrate peaking and lead to the development of nitrate selective resins
- Nitrate peaking is where the nitrate in the effluent from an IX column exceeds the feed water levels
> Nitrate selective resins were made by increasing the degree of cross-linking in the resin structure and incorporating bulkier amines into the structure to favour the single bond with NO3 over the double valent SO4
> We talk later about an inner core of strongly bound nitrate selective sites – what the manufacturers did was to increase the ratio of this core volume to the more easily regenerated outer sites – nitrate peaking still happens on nitrate selective resin, we just don’t see it because there’s sufficient capacity available in the inner core to absorb nitrate sledged off the outer sites
designed for farmers
NTPlus uniquely recovers nutrients from wastewater and nitrate removal plants in liquid form, compatible with smart irrigation and greenhouse growing. We produce high nitrate irrigation water, low nitrate drinking water, and convert potash into sulphate of potash – a nutrient that improves a crop’s drought, disease and stress resistance – that has to be good!
proof of concept
Red Russian Kale at 3 weeks, 40% of nutrients recovered at a carbon cost of 1/5th of conventional production
97% of potash (KCl) converted to K2SO4, KNO3 and KHCO3
nitrate
The most common fertiliser. The problem is that nitrate is very mobile in soils, so most just disappears – and this has been going on for decades. There’s now between 7 and 20 years supply of nitrate under our feet, slowly heading down to the aquifers. It’s called the ‘Nitrate Timebomb’.
wastewater
As a final effluent treatment process, this recovers high quality irrigation water with extra N in it, produces low N drinking water, and converts potash to sulphate of potash.
