Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in ...

The integration of up-concentration processes to increase the efficiency of primary sedimentation, as a solution to achieve energy neutral wastewater treatment plants, requires further post-treatment due to the missing ...

Nitrogen recovery and valorization is gaining interest due to the current need for nitrogen removal, so it is of great interest that ammonium-selective sorbents be evaluated. In this study, a zeolitic material synthesized ...

An extensive experimental campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li+ ~ 4000 ppm) is presented to identify the best operating conditions for a Li2CO3 crystallization unit. Lithium is currently ...

Here, an alternative nutrient (N-P-K) recovery route from potassium-rich sludge anaerobic digestion side-streams using powder reactive sorbents (PRSs) is presented. In the first step, the optimum PRS system was determined ...

The production of olive oil and wine are two of the main agri-food economic activities in Southern Europe. They generate large amounts of solid and liquid wastes (e.g., olive pomace, olive mill wastewater, grape pomace, ...

L’industria chimica moderna concentra gran parte delle sue risorse nella gestione dei residui che derivano dai diversi processi produttivi. L’obiettivo principale è gestire questi residui nel rispetto dell’ambiente, ...

Acidic mine Drainage (AMD) is still considered one of the greatest mining sustainability challenges due to the large volumes of wastes generated and the high associated treatment cost. New regulation initiatives on sustainable ...

Acidic mine waters (AMWs) contains moderate concentrations of sulphuricacid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes ...

In this work, the rejection of two ions associated with fertilizer pollution of ground water (NH4and NO3) by a polyamide nanofiltration (NF270) membrane was studied. Sodium chloride was selected as the dominant salt and ...
