Better membranes for cleaner water

ID: F1601-10

A brand new project developed revolutionary membranes. They featured greatly increased surface area and longer working life. In addition, the membrane price per membrane area had been considerably reduced. A nano-filtration coating enables surface water to be filtered straight and used as ingesting water using the help of a low-volume, low-energy filtration process. Moreover, the ceramic material is resistant to fouling, ensuing in lower operating expenses and less time lost for membrane cleansing. The membrane is strong sufficient to help back flushing during cleansing and sterilisation with chemicals or hot vapor. Lower maintenance requirements will end up in less cleansing chemical compounds being needed and therefore disposed of. The membrane can additionally run at low stress thanks to its large permeability and low fouling propensity, thereby saving energy and reducing procedure costs. The method can be used to provide emergency water supply and neighborhood water therapy, as well as for large-scale production of ingesting water through the filtration of surface water. The membrane can additionally be utilized for treating wastewater from specific procedures characterised by high conditions, extreme PH values, aggressive chemicals and/or extreme fouling behaviour.

    Nano materials for water purification

    ID: F1601-02

    Water scarcity is one of the main challenges of the twenty-first century. Novel low-cost, bio-based filtration and purification membranes promise increased access to clean water for all. Water use has been growing at two times the price of the populace during the last century. Every 12 months, competition for water resources for ingesting, washing, and sustaining farming and life intensifies. A new project is developing nanomaterials-based water purification membranes for decentralised commercial and domestic water therapy to help relieve the issue. Scientists are designing, developing and testing membrane-based prototypes based on nanocellulose and/or nanochitin, polysaccharides discovered in plants and the exoskeletons of crustaceans. The primary focus is on the removal of toxic chemical compounds such as heavy metal ions, pesticides and fertilisers from contaminated industrial water making use of membranes and membrane modules. The membranes will be evaluated for their suitability for disposal by composting and its effect on environment, at end-of-life. These bio-based functional membranes therefore offer an extremely energy-efficient, cheap, biodegradable, non-toxic and green substrate for water therapy. Using existing industrial processes, the team was able to quickly up-scale manufacturing of nanoparticles (cellulose and chitin nanocrystals and cellulose nanofibres) isolated from bioresources. Nanocellulose and nanochitin have demonstrated satisfactory adsorption of hefty metal ions from water for efficient water purification. Researchers prepared 100 % bio-based membranes from cellulose nanocrystals, cellulose nanofibres and chitin nanocrystals in indigenous type as well as from surface-modified cellulose nanocrystals. Various changes were tested to improve filtration, mechanical properties and adsorption efficiency. The project will assist to recover heavy metals while ensuring high-efficiency decentralised water cleansing, high adsorption prices and high adsorption selectivity. It will additionally feature reuseable antifouling or low fouling areas. The treatment of water toxins will have long-term benefits for individual health and quality of life. This work will lead to brand new products based on green nanotechnology in the form of nanomembranes, filters and adsorbents for water purification that will be much more efficient, cost effective and environment friendly than currently available items. They will offer sustainable solutions for water recycling and elimination, and the recovery of hefty steel ions, fertilisers, medications and pesticides from industrial effluents. The ensuing enhancement in the quality of surface and groundwater, at first in Europe and then at the worldwide level, will have a far-reaching effect on the environment.

      Clean, usable water is at threat from the increasing incidence of hazardous substances in water supplies, threatening general public wellness and the environment. Novel nano-structured membranes are therefore being created by EU-funded scientists to combat the bioaccumulation of heavy metals, the emergence of multi-drug resistant organisms and metal-related diseases. Chronic exposure to hefty metals and drugs from the mining, pharmaceutical and wellness treatment sectors can be toxic to living cells and induce disease processes. A new generation of low-fouling, nano-structured filtration membranes using smart materials may be just around the part. Experts working are developing technology to boost the percentage of potable water in developing and industrialised nations. The three-layer hybrid membrane will have an anti-fouling pre-filter made of polymeric nanofibres, a smart cleaning system employing piezoelectric crystals and a highly selective, nano-structured ceramic membrane. Together, these enhancements will enable the treatment of heavy metals, data recovery of valuable metals and catalytic degradation of toxic compounds. This should find application in the mining industry and pharmaceutical sector as well as in hospitals and geriatric treatment services. One benefit of the idea is that each component may be considered as a separate device. They can be effortlessly combined to supply tailor-made solutions for the certain needs demanded by different water remediation processes. The production procedure for the new filters will be scaled up to industrial level for treating in situ effluents. The advantages of the nanomaterial-based membranes will be carried with respect to water filtration efficiency and economic and environmental impacts. The project will offer a toolbox for fabricating prototype multifunctional membranes for industrial wastewater therapy; it'll concentrate on three industrial programs. These range from the treatment of heavy metals from acid mine drainage water and valuable metals from the chemical and mining industry. They will additionally be used in the catalytic degradation of toxic drugs and metabolites from the pharmaceutical sector and hospitals and nursing houses.

        PVs are solar cells that have аctuallу the possibility to mеet the world's grоwing electrісal enеrgy neеds, if theу сan cоmpete uѕing the price of present energy generation. This could be achieved by reduсing the expense of these solar cells, increaѕing their effеctiveness and reducing their environmental impact. For thiѕ a new 'drу' proсess to reduce the really high level οf water usage by PV mаnufactυring plants has beеn develοped. This will help reducе global warming potential (GWP) emisѕіоns, while increaѕing PV cell efficiency and рroductiοn levels. Silicon etching is a key technology in the prοduсtion of РV cellѕ. The dry etсhing proсedure provides a νery uniform siliсon wafer with a surface textυrе that haѕ low reflectivity and is incredibly efficіent at taking in lіght. The qυantity of ѕіlicon eliminatеd to attain theѕe textures is minimal but reѕultеd in signifiсant price cost ѕavings. Project partnеrѕ created a range of texturеs and non-contact managing prосesseѕ that demonѕtrated the technology's vеrsatility. The nеw PV production prоcess clеarly demonstratеs the аdvantagеs asѕοciated with it. Bу removing the induѕtry's rеlianсе on high levels of lаbour, watеr and GWP сhemiсal substances, a cleaner, greener alternatiνe for solar cell manυfacturers can be provided.
