Abstract

This study aimed to develop an energy‐efficient process for treating highly saline textile wastewater (TWW) in a 10 m3/day pilot plant and evaluate forage sorghum irrigation with treated wastewater in terms of crop production and soil and irrigation device performance. The TWW treatment pilot plant, consisting of a coagulation/flocculation unit followed by a sand filter and an anion exchange resin column, produced treated effluent that complied with the permissible limits specified in the ISO 16075‐2:2020 standard for Category C irrigation water. The corresponding average energy consumption was 1.77 kWh/m3. Reusing treated TWW for forage sorghum irrigation over a 13‐week cycle yielded crop performances comparable with freshwater irrigation, with no negative impact on the irrigation system. Although soil profiles were similar between treated TWW and freshwater irrigation, both soils featured an increase in electrical conductivity, which may reversibly or irreversibly affect soil quality and damage salt‐sensitive crops. These findings demonstrate the effective treatment and reuse of saline TWW for irrigating salt‐tolerant crops, offering significant implications for industrial wastewater management and cropping patterns in arid and semi‐arid regions. Highlights: A 10‐m3/day pilot plant was developed for the treatment of highly saline textile wastewater.The pilot plant demonstrated average removal efficiencies of 63% for COD, 97% for colour, 96% for TSS and 21% for EC.Treated effluent met ISO 16075‐2:2020 standards for Category C irrigation water, with an average energy consumption of 1.77 kWh/m3.The use of treated wastewater showed sorghum crop production comparable with freshwater irrigation.The use of treated wastewater had no adverse effects on the irrigation system; however, it led to an increase in soil electrical conductivity.

Abstract

Abstract: Grape pomace is a polluted waste that is usually deposited in landfills, disrupting plant growth and polluting water. The present study aimed to convert this abundant biomass into a suitable feed for ruminants using white-rot fungi via a solid-state fermentation bioprocess. For this purpose, two white-rot fungi, Ganoderma resinaceum(medicinal fungus) and Pleurotus cornucopiae(edible fungus), and different durations of solid-state fermentation (0, 4, and 8 weeks) were used to determine the best fungus and the optimal duration of solid-state fermentation. The results showed that fermentation of grape pomace with both white-rot fungi reduced lignin and condensed tannin content and increased crude protein and mineral content. This bioprocess improved rumen fermentation and dry matter and fiber digestibility. This enhanced concentration of volatile fatty acids and ammonia-nitrogen in the rumen which contribute to better microbial crude protein synthesis and metabolizable energy by ruminants. Fermentation of these wastes with P. cornucopiaebetter reduced lignin content and improved rumen fermentation and metabolizable energy than with G. resinaceum. However, increasing the fermentation periods with both white-rot fungi reduced the gain of metabolizable energy and ruminal microbial crude protein synthesis. In conclusion, fermentation of grape pomace waste inoculated with P. cornucopiaeafter 4 weeks is the better strategy to bio-convert into suitable ruminant feed. Reduction of feed costs, overcoming of disposal problems of this waste, and provision of a new source of income for the grape juice and wine industry can be achieved through this alternative feed.

Abstract

The rare fungus Hericium erinaceus (Bull.) Pers. was collected from temperate forests in northwestern Tunisia and described for the first time in Africa. In this paper, we report data about the distribution, ecology, morphology and molecular identification of H. erinaceus. Collected data may help expand our knowledge on this critically endangered rare species worldwide. [ABSTRACT FROM AUTHOR]
