Nutromex NP are a range of Nitrogen and Phosphorous liquid blends to optimise plant health and performance in both aerobic and anaerobic wastewater treatment plants.

In biological wastewater systems, micro-organisms metabolise the soluble pollution, producing carbon dioxide, water and more micro-organisms (sludge). To do this, with optimum efficiency, the micro-organisms need a balanced diet that contains the correct ratios of mineral nutrients.

The Nutromex range consists of;

Nutromex 100 series

A range of Nitrogen and Phosphorous blends . The normal ratio for aerobic plants with no N or P input is 5:1 but all ratios can be provided to optimise plant performance. 

Nutromex Plus 200 series

A range of N and P nutrients combined with fully bio available trace elements to provide a completely balanced nutritional additive.

Nutromex 400 series

This series provides Ca, Mg, Na and K cations where they are lacking in an industrial treatment system.

Nutromex Salts 600 series

Ca, Mg, Na and K cations with bio available trace elements used specifically for condensates being treated anaerobically.

Nutromex PP 900 series

A blend of soluble carbohydrates, N, P, trace nutrients and essential cations. This super food is used to augment COD in start ups , over shutdowns and during recovery from toxic shock.
