The main non-biodegradable compounds (soluble microbial product – SMP) of wastewater from the Maotai aromatic factories, located in the Chishui river region, were analyzed by UV spectroscopy, and by solid-phase extraction followed by gas chromatography coupled to mass spectrometry, after a two-...
Non-limiting examples of water-soluble polymers include water-soluble hydroxyl polymers, water-soluble thermoplastic polymers, water-soluble biodegradable polymers, water-soluble non-biodegradable polymers and mixtures thereof. In one example, the water-soluble polymer comprises polyvinyl alcohol. In another...
The demand for advanced biodegradable or biocompatible materials and devices for a sustainable future is powerfully fueling the so-called “green electronics.” This is indeed increasing very rapidly, mainly as a result of the significant growth of electronic waste that has followed proliferation of ...
DNAPL contamination can be even more problematic because many DNAPLs are halogenated hydrocarbons, which tend to sink deeper into the subsurface and which are often more toxic and less biodegradable than LNAPLs. In principle, some DNAPL may be recovered from a subsurface bolus resting at the ...
Among the water-soluble thermoplastic resins used in the present invention, for example, the water-soluble thermoplastic PVA is biodegradable, and is decomposed into water and carbon dioxide by treating with activated sludge or burying in soil. For treating the waste fluid after dissolving and removi...
E1 E2 E3 E4-Exit point for water, disinfectant liquids, anti-grease liquids and / or ecologically non-harmful and biodegradable cleaning products. Said pressure irrigation system is pushed by a pressure pump so that the upper part of the filter can be irrigated, cleaned, and water dropped to...
Biocidal and/or phytosanitary formulation of application in aerosol form based on non-residual biodegradable active substances. The present invention relates to a formulation with biocidal and/or phytosanitary properties and application in the form of an aerosol characterized in that it comprises: (a) ...
The invention relates to a formulation having biocide and/or phytosanitary properties that is used the form of aerosol, characterized in that said formulation comprises: (a) 20 to 60% by weight of a solution of at least an active biodegradable substance having biocide and/or phytosanitary ...
Biocide and/or phytosanitary formulation for aerosol use, made of active biodegradable non-residual substancesThe invention relates to a formulation having biocide and/or phytosanitary properties that is used the form of aerosol, characterized in that said formulation comprises: (a) 20 to 60% by ...
The nature and composition of the waste produced by food industrial processing make its abundance and accumulation an environmental problem. Since these by-products may present a high potential for revalorization and may be used to obtain added-value compounds, the main goals of the technological ad...
