Making water drinkable with nanotechnology: it’s now a reality!

Discover the project for “removing and capturing” microcontaminants with recycled materials

Micropollutants, or microcontaminants, are chemicals such as pesticides, drugs, medicines and other organic substances that are present in water in very low concentrations. These are substances that are hazardous to human health and the environment, which we constantly monitor and research in order to identify effective removal mechanisms and abatement technologies.

“Removing and capturing” microcontaminants

The project involves the use of materials recovered from the production of hollow fibres for membranes, such as scaffolds used in the medical field which, combined with graphene, can be used as filter material in the water purification process.

In this way, a valuable material, which would otherwise be lost as process waste, is put back into circulation and given new life.

Laboratory tests were performed comparing conventional materials, such as activated carbon and innovative materials (PSU-GO, RGO, GNP, etc.) for the treatment of water resources at the Pontelagoscuro (Ferrara) power plant.
The objective of the test was to verify the effectiveness of these materials in removing various micropollutants, such as: EMPs (Emerging MicroPollutants), EPs (Emerging Pollutants) and possible by-products of ozonation, such as bromates.

The results highlighted the effectiveness of certain filtering materials and the next step will be the construction of a pilot plant within the Pontelagoscuro power plant, to further study and perform further tests on a larger scale.

Wastewater "gets beautiful" with ultrasound treatment

Wastewater "gets beautiful" with ultrasound treatment Wastewater is all the water that, after having been used in domestic, agricultural, and industrial activities, must be treated before being returned to the environment. This water contains a solid part – sludge – which is removed during treatment. But, in addition to giving a new life to wastewater, can we also make the sludge life cycle circular, by reducing the amount to be disposed of? Back in 2017, we started research to answer these questions, and, once again, we decided to invest in new technologies to lighten the impact on the environment and be more virtuous. In November 2019, our efforts became a reality, thanks to the ultrasound sludge hydrolysis system, installed at the Forlì treatment plant. In this system, part of the sludge from the wastewater treatment process is subjected to sound waves. The waves, in contact with the liquid matrix to be treated, biodegrade more volatile solids, increasing biogas production, and reducing the final dry matter in the sludge. All this makes it possible to significantly reduce the volume of sludge to be disposed of and opens up new scenarios for the use of the biogas obtained thanks to the ultrasound system. During 2020 the initial results will be reported and we look forward to sharing the successes of this new adventure with you. 110_150_depurazione.1597408821.jpg no

Bus fuel from trash: Hera's pilot project with "START"

Bus fuel from trash: Hera's pilot project with "START" _PG_9554.1555590488.jpg To obtain clean energy to power Ravenna's buses by decomposing waste in landfills. We are not talking about the future, but about what has already come true, thanks to an innovative waste treatment plant in Ravenna. It adds another important element in the effort to reduce environmental impact and optimise waste management. The project is funded by the Emilia-Romagna Regional Administration and the European Commission, and is designed to highlight the advantages of using green natural gas. Which ones? It can contribute to replacing fossil energy sources with renewable energy sources; it can be used in the transport sector by contributing to achieving the 10% share of biofuels; it can provide logistics savings thanks to the extensive Italian natural gas network; and can be integrated with other renewable energy sources. The biomethane is collected from networks inside the landfill, and from there it is channelled into a container where it is "purified" by removing the carbon dioxide and other gases in it. From there, it reaches a tank and is used for refuelling. For now, the biomethane produced by the plant will power the buses of "Start Romagna" (Romagna's public transport company), and the pilot project will last about two years. But this is just the beginning. For the Hera Group, this is the second biomethane production facility, after the one in Sant'Agata Bolognese, which produces green energy by treating mowing, pruning and organic waste from separate waste collection.

A source of clean energy from sewers and wet waste: Biomethane

An investment of Euro 37 million. A plant that disposes of 100 thousand tonnes of organic waste produced by separate waste collection and another 35 thousand tonnes coming from green waste and pruning material.

Biodiesel has been developed also from used food oil

Fuel may also be extracted from vegetable oils. Used domestic vegetable oil (such as frying oil) which is recovered by multiutility services via roadside containers and drop-off points, is transformed into biodiesel, which in turn is used to fuel the vehicles used for urban waste collection.

Dialogue with the urban context for new energy: the Borgo Panigale cogeneration plant

District heating is already in itself a "sustainable" and environment-friendly solution, because it can guarantee better performance than traditional domestic boilers. In addition, the plant located in Borgo Panigale ensures lower emissions into the environment, more reliability and greater availability of energy. The system can heat the equivalent of 8,000 residential units. Currently, the turbines can produce 35,000 MWh of energy per year, almost twice as much as in the past.

Ferrara, the city of "green" heat

What's Ferrara's green secret? It's underground, where a geothermal basin feeds its district heating system. The result? 87% of the thermal energy distributed in the city is "clean" and we avoid about 22 thousand tonnes of CO 2 emissions.
