In recent years, the study of membrane processes for recovery valuable phenolic compounds from olive mill wastewater (OMW) has been intensified. The selected OMW pH ultrafiltration is one variables affecting productivity, selectivity and fouling. An in-depth characterization fouling was performed 150 kDa ceramic tubular selected. At three tested (2, 6 9), a high retention suspended matter 98% a...

Discovering eco-friendly alternatives to synthetic chemicals has become an increasingly popular area of research. Natural products are now in the spotlight for their potential use as replacements chemicals. To maximize benefits these natural products, it is important efficient extraction methods, especially from agroindustrial waste. Olive oil mill wastewater (OOMW) a byproduct olive production...

Olive oil and pig productions are important industries in Portugal that generate large volumes of wastewater with high organic load toxicity, raising environmental concerns. The principal objective this study is to energetically valorize these effluents—piggery effluent olive mill wastewater—through the anaerobic digestion biogas/methane production, by means complementarity concept. Several mix...

In recent decades, olive oil consumption has almost tripled worldwide. Olive production is linked with the of enormous amounts mill wastewater, main by-product derived from three-phase mills. Due to environmental risks wastewater disposal, management and valorization specific waste stream great importance. This work focuses on thermophilic dark fermentation in batch reactors, targeting pH optim...

Different amounts of Ca(OH)2 were added in 2 L beakers containing 1 L of olive mill wastewater (OMW). The mixture was stirred for 45 min and left to settle. Wastewater analysis was used in order to determine the effect of the different amounts of calcium hydroxide in the treating process, three days after the application. The Odor Detection Threshold was used for determining the effect of the t...

Olive mills generate a large amount of waste that can be revaluated. This work aim to improve the production lignocellulolytic enzymes by solid-state fermentation using ultrasounds pretreated olive mill wastes. The composition of olive mill wastes (crude and exhausted olive pomace) was compared and several physicochemical characteristics were significantly different. The use of both wastes in S...

This study investigates the potential use of olive aggregates (OA) in production cementitious materials as a substitute for natural sand to reduce excessive this resource. Two types OA were used: OPA (olive pomace aggregates) and OPMW (OPA mixed with mill wastewater). The aim was determine experimentally whether improvements mechanical properties produced lightened cement mortar could be obtain...
