Nutriox

The Nutriox^® Process

Septicity does not occur everywhere in a sewer network, but only in parts where the dissolved Oxygen has been consumed and anaerobic conditions occur. This can be avoided by using the Nutriox process, which supplies Nitrate to the bacteria present.

Nutriox will cause a change in the bacterial population in the wastewater and the slime lining the sewer.  A bacterial culture is established which not only removes the H₂S that has already been formed, but also prevents the occurrence of septic conditions by suppressing anaerobic bacteria.  By using Nutriox, Carbon Dioxide and Nitrogen gas will be formed, and H₂S will be oxidised back to Sulphur or Sulphate.

Nitrate has high solubility in water and Nutriox is very effective in the treatment of wastewater with a long retention time in the sewer network. Nutriox is used both for municipal sewer systems and industrial wastewater. It is applied at pumping stations, in gravity sewers and in manholes. Nutriox can also be used at various places in a treatment plant where septic conditions occur when wastewater and sludge have a long retention time and a lack of Oxygen.  By continual analysis of Hydrogen Sulphide in septic wastewater, it has been proved that the concentration can vary considerably in the course of a 24-hour period. Variations in dissolved Sulphide, in the range of 1-10 mg H₂S per litre, are not unusual. This means that the need for Nutriox will also vary in the same way. By dosing the correct amount of Nutriox at the right time, all Hydrogen Sulphide will be removed or prevented from occurring. When the dosing of Nutriox is stopped, septic conditions will again occur and Hydrogen Sulphide will be formed.

The dosing of Nutriox depends on a number of factors such as the content of organic substances and Hydrogen Sulphide in the wastewater, dimensions of the sewer network, temperature and wastewater flow. As the composition of the wastewater may vary considerably in the course of a day, there are special requirements for the dosing of Nutriox. In order to avoid applying too much or too little Nitrate, it is important that Nutriox is dosed in a controlled way. For this reason, we have developed a range of dosing controllers to provide controlled and optimal dosing of Nutriox.  For optimisation of the Nutriox process, we depend on close co-operation with the customer. By means of analyses and a mutual understanding of the problem, we can find the best technological and economic solution for each individual customer. This method is beneficial to both parties and increases understanding of both the problem and its solution.

In 1996 we obtained a Queens Award for environmental achievement in recognition of the success of Nutriox^® "for improving the lives of thousands of people".
