Olive manufacturing generates the most polluting wastewater. mill wastewater (OMW) contains a large amount of organic and inorganic fractions. Olive-oil-producing countries have investigated several treatments valorization processes for better management this waste. The Tunisian government adopted OMW spreading on soil to manage waste improve matter in olive groves. examination after was set up...

Phelipanche ramosa (L.) Pomel is a root holoparasitic weed that infested many crops, particularly the processing tomato. In semi-arid regions of world, this problem increasing, both in intensity and acreages. last few years, researches for control parasite has increased its effort to use suitable methods, as well utilization natural compounds. regard, four experimental trials were carried out o...

The purpose of this work was to analyse the potentialities of an integrated membrane system for the recovery, purification and concentration of polyphenols from olive mill wastewater (OMW). The proposed system included some well-known membrane operations such as microfiltration (MF) and nanofiltration (NF), as well as others not yet investigated for this specific application, such as osmotic di...

The production of olive oil in Morocco has recently grown considerably for its economic and nutritional importance favored by the country's climate. After the extraction of olive oil by pressing or centrifuging, the obtained liquid contains oil and vegetation water which is subsequently separated by decanting or centrifugation. Despite its treatment throughout the extraction process, this olive...

The present paper gives a haptic feedback control of a holonomic Omni-directional Mobile Wheelchair (OMW) with a haptic joystick for the operation of disabled people or elderly people considering not only the navigation task but also user’s safety. In the present research a haptic joystick was designed and applied with being maneuverable for users and free of joystick’s vibrations. A way to bui...

The present work reports the application to reduction of organic matter and nutrients in oil mill liquid waste (OMW), using natural calcium bentonite from Morocco as adsorbent. margine is characterized by a high concentration low biodegradable highly toxic matter. In order evaluated capacity remove nutrients, characterization mineralogical, chemical also morphological adsorbent were conducted. ...

The evolution of modern technology for olive oil extraction has affected the industrial sector depending directly on the by-products obtained. The traditional three-phase continuous centrifugation process for olive oil extraction was introduced in the 1970s, notably to increase the processing capacity and extraction yield and to reduce labour. This three-phase manufacturing process of olive oil...

A device (prototype) with a working volume of 200 L was used to deplete olive mill wastewater (OMW) of polyphenols. The OMW transformed into feedstock by means of the device was then used for feeding a lab-scale photobioreactor, just for testing the production of bioH2. The main novelty of this prototype consists in the combination of several adsorbent matrices and the exploitation of their syn...

The environmental impacts of irrigating an olive field with mill wastewater (OMW) and treated (TWW) on soil properties were investigated. effect different irrigation treatments OMW (50 m3 ha?1, 100 200 ha?1) TWW at depths was studied. obtained findings revealed that application augmented pH; EC values; P, K Ca contents in all layers. However, Mg Na concentrations, as well organic matter content...

The aim of this study was to formulate nanodispersions encapsulate antioxidants extracted from olive mill wastewater (OMW) and phycocyanin Spirulina maxima act as enhancers for the skin’s protection against UV radiation. For purpose, two water-in-oil nanoemulsions were prepared using a low-energy homogenization method. Both systems based on isopropyl myristate continuous phase, while water or m...
