Cobalt and Phosphorous Recovery from Semiconductor Wastewater through Homogeneous Crystallization of Cobalt Phosphate in a Fluidized-bed Reactor

Bayon L., Ballesteros Jr. F., Segura-Garcia S., (Corresponding) Lu M.
Topic: 
Heavy metals in the environment
Semiconductor manufacturing involves distinct processes that generate complex wastewater streams that require treatment before it proceeds to the main wastewater effluents. The present study utilized fluidized-bed crystallization to recover resources from the combined synthetic wastewater of...Read more

Applying solar distillation for the sustainable management of olive mill wastewater

Mastoras P., Gatidou G., Vakalis S., Fountoulakis M., Haralampopoulos D., (Corresponding) Stasinakis A.
Topic: 
Wastewater treatment
Olive mill wastewater (OMWW) is a major by-product of olive oil production industry. Its chemical characteristics (high concentrations of COD and TSS, low pH value, existence of total phenols at the range of some ppm) does not allow its efficient treatment using conventional physiochemical or...Read more

Catalytic reduction of Cr(VI) using recovered Silicon from end-of-life photovoltaic panels as a catalyst

Pavlopoulos C., Kyriakopoulou V., (Corresponding) Papadopoulou K., Lyberatos G.
Topic: 
Wastewater treatment
As installed photovoltaic panels (PVP) approach their end of life, the need for a sustainable recovery plan becomes imperative. This work aims to reuse Silicon from End-of-Life PVP as a potential catalyst/photocatalyst for wastewater treatment. PVPs were pretreated thermally (550°C for 30 min). The...Read more

Optimum technical operating conditions and treatments for the production of high-purity struvite fertilizer from livestock wastewater.

Kallikazarou N., Koutsokeras L., Constantinide E., Constantinides G., (Corresponding) Antoniou M.
Topic: 
Biowaste
Inadequate treatment of nutrient-rich waste streams originating from human activities such as agriculture, animal breeding, urbanization, and industrialization causes an array of environmental problems. Among them are eutrophication of surface water, nutrients and pathogens leaching into...Read more

Energy recovery from urea in decentralised wastewater streams

Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic: 
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen. Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more

Oxic-Settling-Anaerobic under intermittent aeration: effect on system performance, sludge minimization and greenhouse gas emissions

Dı Trapanı D., Cosenza A., (Corresponding) Bosco Mofatto P., Mannina G.
Topic: 
Wastewater treatment
The paper presents the results of an experimental study carried out on a pilot scale activated sludge system operated under intermittent aeration and fed with real wastewater at the Water Resource Recovery Facility of Palermo University (Italy). The experimental campaign was divided into two...Read more

Coffee ground biosorbent for nitrite and nitrate recovery and soil nutrient

Ying T., (Corresponding) Sethupathi S., Hon L.
Topic: 
Recycling of materials to new products
Nitrate (NO3-) and nitrite (NO2-) are two forms of nitrogen that contribute to the occurrence of eutrophication if found in excess concentrations. Conversely, nitrogen is one of the major macronutrients required for healthy plant growth. The purpose of this work is to evaluate the recovery of NO3-...Read more
