Biogas upgrading to biomethane

Posted on January 17, 2020 New

Upgrading biogas to biomethane is a very interesting technology to purify biogas to recover methane, which can be used as an alternative to fossil fuel. Biogas is a renewable energy resource that can be generated from the anaerobic digestion of wastewater sludge and from many other industrial and agricultural wastes.

Phosphorus recovery

Posted on December 30, 2019 New

Phosphorus is an essential element of life and is fundamental in agriculture. Being a non-renewable and limited resource, the growing demand for fertilizers is gradually depleting the phosphate rock reserves. Thus, rationalizing the use of this resource and promoting its recovery is an issue of emerging concern.

Operations and Maintenance (O&M)

Posted on December 30, 2019 New

Sludge treatment facilities are characterized by increasing expectation in service, operation and control; therefore the costs for normal operation are usually rather high. Thus, operational expenditures over the whole lifecycle of a treatment plant are a key factor in a cost-effective perspective.

Wastewater disinfection

Posted on August 5, 2019

Wastewater reuse in agriculture is fundamental for the water utilities to move toward a circular economy approach to water as are source. However, reuse in agriculture requires treatments with high efficiency in pathogens concentration abatement.

Relationships with stakeholders

Posted on August 5, 2019

The word "stakeholder" in the last few decades has become commonly used to mean a person or organization that has a legitimate interest in a project or entity. In the decision-making processes of a water utility the regulatory prescriptions and the constraints dictated by the authorities obviously have a fundamental role; however, relations with civil society stakeholders also are of considerable importance.

Emerging micropollutants

Posted on July 15, 2019

Emerging contaminants have long been the subject of attention by the scientific community: it is a large group of chemical compounds that are found in very low concentrations in wastewater. They are particularly difficult to treat with existing technologies, however, some possible solutions have already been found out: those solutions now need to be verified in full-scale treatment plants.

Co-digestion

Posted on July 15, 2019

Anaerobic digestion is a biological process usually applied on the sludge produced in municipal wastewater treatment plants. Co-digestion is a way of managing the process which, if properly exploited, can guarantee better results in biogas production as well as some other overall benefits in waste management.
