The fate of microplastics in an Italian Wastewater
Selected Wastewater Treatment Plant (WWTP) removes the 84% of microplastics (MPs). • 160,000,000 MPs were released daily by selected WWTP. • 3,400,000,000 MPs were deposited daily in 30 tons of sludge by selected WWTP. • WWTPs are a source of MPs in both aquatic and terrestrial environment.
An overview of water availability and distribution, water consumption, wastewater treatment trends, with particular reference to advanced ones, is briefly presented. Data about the current situation of municipal wastewater treatment and advanced treatment options are presented and regional trends about wastewater reclamation (agricultural and
Evaluation of the energy efficiency of a large wastewater
Evaluation of the energy efficiency of a large wastewater treatment plant in Italy. Energy consumption represents a significant part of the operative costs of a wastewater treatment plant but, with a correct design and a careful management model, there are important possibilities for its limitation.
The Milan—Nosedo wastewater treatment plant in Italy is one of the largest in Europe, requiring submersible electric pumps that can handle heavy duty conditions in a large operation. Here, we see how Caprari has continued to provide the solution for more than a decade, not as a supplier, but instead as a well-respected and reliable partner.
Licit and illicit drugs in a wastewater treatment plant
The occurrence of 12 active substances among licit and illicit drugs was investigated over a 2 week period inflowing and outflowing in an activated sludge wastewater treatment plant in the city of Verona, Northern Italy.
Two wastewater treatment plants have been monitored in terms of illicit drugs. • Cocaine and cannabis metabolites have been found in both plants. • High average removal efficiency were found for MOR (90.16%) in WWTP-1. • Population consume 1.6 doses per 1000 inh −1 day −1 of cocaine. •
A review of nature-based solutions for urban water
Larsen & Gujer (1997) defined UWM as a combination of water supply, urban drainage, wastewater treatment and water-related sludge handling. Accordingly, UWM includes the plan, design and operation of infrastructure to secure drinking water and sanitation, the control of infiltration and stormwater runoff, recreational parks and the maintenance
A waste water treatment plant cleans sewage and water so that they can be returned to the environment. These plants remove solids and pollutants, break down organic matter and restore the oxygen content of treated water. They achieve these results through four sets of operations: preliminary, primary, secondary and
Production of Electricity during Wastewater Treatment
Microbial fuel cells (MFCs) have been used to produce electricity from different compounds, including acetate, lactate, and glucose. We demonstrate here that it is also possible to produce electricity in a MFC from domestic wastewater, while at the same time accomplishing biological wastewater treatment (removal of chemical oxygen demand; COD).

Aerobic treatment of dairy wastewater in an industrial
The wastewater characteristics are reported in Table 1. 2.2. Wastewater treatment plant (WTP) and operative conditions The WTP, designed and manufactured by Manzi Aurelio Srl (Montefiascone, Italy), is constituted of a primary section for sedimentationof200m3,threeaeratedreactors(R1,R2andR3) connected in series and of 18 m3 capacity each and
Downloadable (with restrictions)! Currently almost all wastewater treatment plants (WWTPs) require a large amount of energy input to process the influent, mostly as electricity, and the associated carbon emissions are in aggregate significant. In order to achieve carbon neutrality, it is important to understand direct and indirect carbon emissions generated by WWTPs.
- What type of sludge is used in a sidestream plant?
- The centrate to the sidestream plant was composed of approximately 80% post THP-MAD sludge dewatering reject liquor and 20% pre-THP reject liquor.
- What is the operating temperature of a sidestream liquor treatment plant?
- The sidestream plant is normally operated at temperatures of around 30–35 °C (average 32 °C). Under steady state conditions, the Anammox reactor is typically operated at pH 6.8 (±0.2). Schematic flow diagram of the sidestream liquor treatment plant at Tilburg comprising a Phospaq struvite reactor and Anammox reactor.
- Can thermal hydrolysis dewatering liquors be treated with biological nitrogen removal?
- Inhibition of thermal hydrolysis dewatering liquors All four technologies achievedsuccessful biological nitrogen removal with 0.10 to 0.60 kg N m −3 d −1 treating dewatering liquors originating from THP/AD.
- What NH 4 N & po 4 p in the dewatering reject liquor?
- NH 4 -N and PO 4 -P in the dewatering reject liquor. Figure 5 presents the COD to and from the sidestream plant. At full operation of the THP, the COD load to the sidestream plant increased to 4,000–5,000 kg/d while COD in the outlet reached around 1,500–2,100 kg/d.
