We can help you comply with the latest effluent discharge limits.

Tightening regulations, corporate social responsibility (CSR) and public pressure raise the bar for effluent discharge requirements. Conventional technologies are struggling to keep up with the ambitious targets regarding water disposal into the environment. The current biological treatment technologies, although crucial for the removal of organics, nitrogen and phosphorus, are not capable of tackling all the present environmental challenges without additional technologies.

Biological treatment

Basic wastewater treatment is performed in an efficient and robust manner by bacteria. For this reason, anaerobic and aerobic systems will continue to be the cornerstone of most treatment plants. A solid design and smart operations of these biological reactors ensures excellent removal efficiencies of organic material and nutrients while keeping energy and chemical consumptions under control.


• Anaerobic wastewater treatment
• Advanced aerobic treatment
• Nutrient removal and N- & P-recovery

"By considering wastewater as a resource, the way we produce fundamentally changes."

Environmental regulations impose increasingly stringent discharge limits. The EU Water Framework Directive has already identified ‘priority substances’ whose emissions and discharges must be phased out. Simultaneously, there is an increasing public debate about the impact of the so-called emerging contaminants on human health and the environment. Micropollutants such as pharmaceuticals, pesticides and ‘forever’ chemicals such as PFAS are difficult to remove with conventional technologies and present new challenges to the industry.

• Directives and regulations, from a global to a local level
• CSR & best practices
• Environmental permitting


Nuoro masters a broad spectrum of technologies for effluent polishing. We start by making a detailed assessment of your situation and then propose a customized treatment strategy. This strategy may consist of optimizing the existing treatment infrastructure or expanding the treatment plant with post-treatment steps, as combining purification steps in an innovative treatment train is the best guarantee for future-proof effluent treatment, especially for ‘emerging contaminants’ and micropollutants.


• Micropollutants & emerging contaminants (ECs)
• Nutrient polishing
• Advanced instrumentation & automation
• Post-treatment
• Advanced oxidation, activated carbon, filtration

water treatment
& reuse

We can help you close the cycle and minimize your water footprint by implementing the best available water treatment and reuse technologies.

Awareness about water scarcity and the current focus on creating a circular economy highlight the growing demand for water recovery strategies. We guarantee that your water needs will be met at all times while paying special attention to your water footprint.


Whether the source is surface water, well water or bio-effluent, a well designed water treatment plant (WTP) is the result of combining the right treatment technologies. Multi-barrier treatment systems are the best option for your potable and process water production. A system designed by Nuoro not only delivers exceptional water quality, but also protects your water production from unnecessary downtime and avoidable water losses while minimizing energy and chemical consumption.

• Sedimentation, pre-filtration
• Multimedia filtration (MMF)
• Activated carbon filtration (ACF)
• Stripping & degassing
• Customized water, re-mineralization, high purity H2O

• Microbiological control & disinfection

“Many industries are sitting right on top of the most sustainable freshwater resource: their own bio-effluent!"

Membrane filtration is a high-performance water treatment strategy. Our team will find and implement the best available filtration solutions, from proven ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) technologies to state-of-the-art high recovery reverse osmosis (HRRO) systems. The current shift from vetted technologies towards high-recovery applications requires special attention when designing your system and even the best treatment systems are not perfect until an appropriate processing plan for the brine stream is determined.

• High recovery reverse osmosis (HRRO)
• Ultrafiltration (UF)
• Reverse osmosis (RO) and nanofiltration (NF)
• Brine & Concentrate Handling | treatment/concentration/evaporation
• Membrane degassing
• Continuous electrodeionization (EDI)


Wastewater should be considered a valuable resource. Recovering wastewater and closing the loop results in direct environmental and economical gains. Treated bio-effluent can be upgraded to any water quality, depending on the intended use and the local regulations. Applications for recycled water can include irrigation, cooling, industrial process water and even potable water production.

green energy

We can help you convert your organic waste streams into clean biomethane. Go for zero emissions and reduce your climate impact.

By creating the Green Deal, the EU aims for net zero emission of greenhouse gases by 2050. As a direct result, emissions of CO2, CH4, N2O and other greenhouse gases are being mapped and quantified. At Nuoro we assist you in identifying the best measures to minimize your emissions and shift to green, renewable energy sources, like biogas.

Anaerobic Digestion

Anaerobic processes are considered an environmentally friendly option for waste management and for wastewater treatment. Essentially, organic waste or high-strength wastewater is biologically converted into bio-methane, a valuable renewable fuel. This biochemical process takes place in specially designed bioreactors. The ‘anaerobic advantage’ is three-fold: clean energy is produced and organic waste is eliminated, while the operational costs for electricity and waste sludge disposal remain minimal.

• Anaerobic digestion
• Reactor and digester design
• CSTR, UASB, high rate upflow reactors
• Feedstock pretreatment, mixing and hygienization
• Seed sludge

“Biomethane production has never been more relevant and accessible than today.”
Biogas processing

Biogas can be converted into electricity and heat or upgraded to bio-methane for fuel use. Gas produced in anaerobic reactors must be processed and pressurized before it can be valorized. Typical treatment steps include drying and the removal of corrosive H2S and other impurities such as siloxanes. For bio-methane production or injection into the natural gas grid, CO2 and other gases are eliminated to obtain pure CH4.


• Biogas desulphurization
• Biogas drying & compressing
• Biogas purification 

Climate action

To support the renewable energy revolution, Nuoro strives to optimize anaerobic digester plants and to maximize the conversion of organic waste into green biogas. Greenhouse gas emissions must be eliminated to avoid counterproductive effects.

Because methane is 25 times more powerful than carbon dioxide at trapping heat in the atmosphere, Nuoro specializes in tracing and eliminating biogas losses.

• Maximizing biogas yield
• GHG-emission monitoring and reduction
