Photochemical UV/TiO2 treatment of olive mill wastewater (OMW).
Olive mill wastewater (OMW) was treated by photocatalysis using TiO2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached 22%, 57% and 94%, respectively. The differences between these three values indicate the persistence of colourless, non-phenolic compounds. Appli...
متن کاملXanthan Production from Olive-Mill Wastewaters
Olive mill wastewaters (OMW) are a by-product from olive oil manufacture that cause environmental pollution. These wastes have been used as substrate for the production of the extracellular polysaccharide xanthan by Xanthomonas campestris NRRL 31459-S4L41. Growth and xanthan production on dilute OMW as a sole source of nutrients were obtained at OMW concentrations below 60%, yielding a maxima1 ...
متن کاملCactus an eco-friendly material for wastewater treatment: A review
Renewable approaches involving the use of natural materials for pollutant removal from wastewaters can offer a favorable solution fitting well with the definition of sustainability. Materials from biological origin (Bean, Moringa, Maize, etc.) have been investigated for their potential use for wastewater treatment. Interestingly, cactus, an abundant plant, offers various options for the treatme...
متن کاملThe effect of olive mill wastewaters variability on xanthan production.
AIMS Xanthan production by Xanthomonas campestris from several olive mill wastewaters (OMW) was investigated. METHODS AND RESULTS Maximum xanthan production of 4 g l(-1) was obtained in media with 50% OMW as sole source of nutrients. OMW storage decreased effluent quality for xanthan production. The range of effluent concentration for X. campestris growth and xanthan production varied dependi...
متن کاملFertilizer NPK from human urine and olive oil mill wastewaters
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
