Abstract A large number of publications are available in the literature regarding olive mill wastewater treatment methods. However, none proposed methods can be considered as a best method terms its effectiveness, and environmental economic impact. Using survey, data were collected evaluated order for sustainability benchmarking analysis to developed. Physicochemical, biological advanced oxidation judged their impact cost. Effectiveness each was estimated COD phenolic compounds reduction, CO...

Replacing conventional materials with new recycled is one of the goals sustainable development, as it promotes creation environmentally friendly products while reducing amount waste to be treated. A common recyclable stream associated urban living glass, which typically comes from packaging or product containers. Although most this can reused and/or recycled, worth exploring alternative uses, especially for areas high fluctuations in glass production. An example would sudden increase tourist...

Liquid and solid waste management is one of the most important challenges 21st century, as continued population growth, intensive agriculture, urbanization industrialization have led to increased pollutant loads on natural ecosystems [...]

BACKGROUND Many physicochemical, biological and disposal technologies have been suggested for the effective treatment of olive mill wastewaters (OMW), wastes with very high organic content, non-readily degradable content phytotoxic characteristics, considered one major polluting agents in Mediterranean countries from agricultural activities. RESULTS The OMW by means coagulation–flocculation using various inorganic materials (poly-aluminum chloride – PAC, aluminum sulphate) poly-electrolytes...

The aim of the present study was to explore high-yield production hydroxytyrosol, a phenolic compound with very high antioxidant capacity. Olea europaea leaves were chosen as feedstock they contain significant amounts oleuropein, which can be hydrolyzed hydroxytyrosol. techniques are widely used in industry and easily scaled up. Olive underwent drying mechanical pretreatment extractives transported solvent by solid-liquid extraction using water-ethanol mixtures. use approximately 60-80%...

Coagulation/flocculation process is considered as a nonexpensive and effective method to reduce organic inorganic content of industrial wastewaters. In the present study series polyelectrolytes were tested optimize existing procedure with new chemical reagents that resulted in removal percentages up 93%. Organic load expressed terms oxygen demand, particle size distribution, pH, ζ potential suspended particles among parameters investigated for best coagulation/flocculation paint The target...

The extraction of olive oil generates huge quantities solids and high organic wastewaters with toxic constituents that have a great impact on land water environments. Based membrane process, authors proposed an alternative method for treatment mill (OMWs). In the present paper, technoeconomic analysis implementation in entire Region Western Greece (RWG) is presented. This paper takes into account fixed operational costs, costs infrastructure, equipment, land, maintenance, so forth,...

The aim of the current study was exploitation agro-industrial wastes or by-products such as olive mill wastewater (OMW) and defective wines. A cost-effective system for their maximum is suggested, using a combined process membrane filtration other physicochemical processes. Wastewaters are first treated in (prefiltration, ultrafiltration, nanofiltration, reverse osmosis) where pure water organic fractions (by-products) obtained. Organic fractions, called hereafter byproducts not wastes,...

Used disposable nappies constitute a waste stream that has no established treatment method. The purpose of this study was the assessment dark fermentation used and expired food products under different pH values. biodegradable part recovered co-fermented with originating from supermarkets. recoverable economic potential process examined for volatile fatty acids exploitation schemes strongly affected products, optimum hydrogen production at 6 (4.05 NLH2/Lreactor), while amount produced...

Phenolic compounds are important secondary metabolites often found in nature, and most prominently plants. Plant biomass residues can be a sustainable source of this high-added-value group that used the food cosmetics industries due to their antioxidant properties. Olea europaea is widely studied phenolic compounds, with olive leaves being an untapped solid residue high content. Coffee after coffee extraction another stream rich phenols. In work, extracts these two substrates, alongside...

Abstract BACKGROUND Coagulation/flocculation is a physico‐chemical method for the treatment of olive mill wastewater ( OMW ). and precipitation agglomerates formed relies on effective decrease electrical charge suspended solids which allows particles to approach each other form large clusters. The present work focuses by monitoring changes in zeta potential particles. This can also indicate with accuracy exact concentration coagulant or flocculant that must be added wastewaters, achieve...

Olive mill wastewater is an important agro-industrial waste with no established treatment method. The authors have developed a phenol separation method that could potentially cover the cost of waste. purpose this study was to identify any economic hotspots in process, operational and examine margin profit for such process. equipment scaled different capacities then used estimate fixed capital investment yearly cost. highest purchased identified membrane filtration system, while resin...
