ENERGY EFFICIENCY

Thanks to a partnership with an ESCo (Energy Service Company), the companies of group are able to design high energy efficiency water treatment systems, that allow not only saving, but sometimes also production of energy. White certificates for energy efficiency interventions and benefits for employ of innovative technologies involve operating costs reduction, that favours the return on investment.

HIGH ENERGY EFFICIENCY EVAPORATORS

Evaporation is a very efficient technology for wastewater treatment, but with high operating costs due to building materials and considerable thermal energy needs. Careful feasibility studies define the choice of more convenient evaporation technology (hot water or vapour, mechanical steam recompression, heat pump) for each different case, evaluating the application of devices, as creation of vacuum in ebullition chamber and employ of more evaporation tanks (multiple effects), that facilitate the return on investment thanks to energy saving.

BIOGAS PRODUCTION

The UASB (Up-flow Anaerobic Sludge Blanket) biological technology can be applied to wastewater with a high COD (Chemical Oxygen Demand) level, as that of food, chemical and pharmaceutical industries. It allows not only to lower pollutants concentration in effluents, obtaining a treated water recyclable in working process, but also to generate energy: bacteria composing the sludge blanket, indeed, digest carbon, producing biogas.

DIGESTATE VALORIZATION

The process of treatment of digestate from biomass plants for COD, heavy metals and nitrogen removal, allows at the same time a valorization of effluent through the recycling of its liquid and solid by-products, that can be used as soil fertilizers and improvers or combustibles for power generation.

SOLAR ENERGY MOBILE UNITS

Reverse osmosis and MBR mobile treatment units have spread for water desalination and potabilization in rural communities or in emergency situations. Connection with a photovoltaic panels system make the plants, remotely monitorable, energy autonomous.

INNOVATION IN MEMBRANE FILTRATION SYSTEMS

One of main problem of reverse osmosis and nanofiltration plants is the creation of mineral scaling, causing a slowing down of filtering action and in consequence also a growth of energy consumptions. An innovative technology is able to prevent the event, optimizing the output of desalination processes: it allows indeed to recover over 90% of water, to reduce until to 60% concentrate to dispose, to minimize or avoid antiscalant chemicals use and to lower energy consumptions.

CIRCULAR ECONOMY

The company, that has between its controlled academic spin off, pay particular attention to research evolution, technological innovations and upgrading of European and national laws about treatment and valorisation of waste and water and renewable energy sources as solar, wind, geothermal and hydroelectric.
