Nyex systems are designed to tackle this variation of wastewater composition. Below are a few of our services for this sector…

COD polishing to low levels

Our water treatment process is designed to reduce COD to trace levels from both industrial
wastewater and specialty chemical washwater.

Recalcitrant organic compound removal

Nyex can remove persistent organic chemicals and micropollutants from wastewater, enabling safe discharge to sewer or water reuse as part of a ZLD strategy.

Avoiding the high costs of incineration

We have helped several clients save significant costs by using our unique treatment process to
reduce their incineration needs.

We have been working with Arvia to try to reuse more of our wastewater and to meet new regulations. We have seen impressive R&D results in the removal of 1-Phenoxy-2-propanol and are now looking to pilot.”

Benefits of a Nyex water treatment process?

The unique Nyex Rosalox™ technology uses adsorption to localise pollutants at low and trace levels which are often missed by generic wastewater treatment methods. It then oxidises the impurities to H₂O, H₂ and CO. If your existing tertiary water treatment is not performing then we might be able to help.

We remove organic compounds to very low levels due to our unique combination of adsorption and oxidation. Nyex water treatment systems are extremely effective at breaking down and removing persistent organic compounds like phenols so are particularly suited to the specialty chemical industry.

Our Nyex water treatment processes have been designed to tackle the wastewater issues faced by the fine and specialty chemical sector, with these key benefits:


Safer and less maintenance

No chemical dosing means less COSHH compliance and operator time. No secondary waste streams means no need to stop production whilst sludge is removed and incinerated.


Targeted water treatment to low levels

Targeted treatment of wastewater to remove toxic, mutagenic, carcinogenic or non-biodegradable contaminants.


Low energy

Unique combination of adsorption and electrochemical oxidation in Nyex process means less energy is used to reduce organic compounds from water.


Modular, scalable design

Nyex water treatment systems are modular and can be turned on and off according to demand, meeting your loadings. Particularly suited to batch processing of specialty chemicals. Further modules can be added based on manufacturing activity, ensuring the longevity of your investment.


Increased efficiencies and reliability

Our Nyex systems can be retrofitted into existing treatment trains to remove the final problematic compounds which traditional treatment systems often leave behind. Improve efficiencies and reliability of existing treatment processes by removing fouling organics and hazardous organic chemicals at key points in the chain.


Flexible positioning

The treatment system is also unaffected by toxins or high temperatures and emits no odour. This means the system will fit easily into your manufacturing environment. Alternatively, systems can bepositioned externally to allow the expansion of your business activities inside the plant to take priority.


Eco friendly water treatment

No chemical dosing and no waste products – eco friendly. A major asset in the plan to reuse water, reducing costs and improving CSR.

Applications of Nyex wastewater treatment systems

Rather than using chemicals to treat water, we use a patented combination of adsorption and electrochemical oxidation which is effective without chemical dosing. This reduces maintenance and COSHH obligations which reduces risk and increases safety and cost savings.

Due to the modular low maintenance nature of Nyex, it is used in several applications as follows:

Customised industrial wastewater treatment

Nyex systems can be positioned as a complementary process to increase the effectiveness of existing water treatment processes. For example, it can be used upstream of an RO system to protect the expensive membranes or downstream, treating the reject stream before incineration.

Also it is often used by clients to protect biological processes from hazardous chemicals such as phenol.

Blowdown water treatment

You might have boilers as part of your manufacturing site. Boilers and cooling water loops need regular ‘blowdown’ treatment to remove any residual chemicals.

This blowdown water may need to be treated before discharge if it contains any harmful chemicals. Our treatment systems are effective in removing the organic chemicals often found in blowdown water. We can remove corrosion inhibitors (azoles) and biocides as well as other organic compounds which might be in the water. We do not provide chemical treatment services or removal of inorganic contaminants.

Water reuse and ZLD

Further challenges arise in the form of regulation for the reduction of clean water use, which encourages the implementation of process water recovery as part of your business as usual activities. We can help you with your Zero Liquid Discharge (ZLD) strategy.

Nyex™ treatment systems can used to ensure treated water is safe for reuse within the business. The ability to safely reuse process water reduces utility costs. It also helps to build positive Corporate Social Responsibility through the protection of the environment in water stressed times.
