Industrial and municipal wastewaters are potential resources for production of microalgae biofuels. Dalton - the Carpet Capital of the World generates 100-115 million L of wastewater d(-1). A study was conducted using a wastewater containing 85-90% carpet industry effluents with 10-15% municipal sewage, to evaluate the feasibility of algal biomass and biodiesel production. Native algal strains were isolated from carpet wastewater. Preliminary growth studies indicated both fresh water and marine algae showed good growth in wastewaters. A consortium of 15 native algal isolates showed >96% nutrient removal in treated wastewater. Biomass production potential and lipid content of this consortium cultivated in treated wastewater were approximately 9.2-17.8 tons ha(-1) year(-1) and 6.82%, respectively. About 63.9% of algal oil obtained from the consortium could be converted into biodiesel. However further studies on anaerobic digestion and thermochemical liquefaction are required to make this consortium approach economically viable for producing algae biofuels.
工业和市政废水是生产微藻生物燃料的潜在资源。作为“世界地毯之都”，达顿每天要产生 1 亿至 1.15 亿升废水。本研究使用一种含有 85%-90%地毯行业废水和 10%-15%城市污水的废水，评估藻类生物量和生物柴油生产的可行性。从地毯废水中分离出了土著藻类菌株。初步生长研究表明，淡水和海水藻类在废水中均生长良好。15 种土著藻类分离株的混合物在处理后的废水中表现出>96%的养分去除率。该混合物在处理后的废水中的生物量生产潜力和脂质含量分别约为 9.2-17.8 吨/公顷/年和 6.82%。从该混合物中获得的藻类油约有 63.9%可转化为生物柴油。然而，需要进一步研究厌氧消化和热化学液化，使该混合物在经济上可行，以生产藻类生物燃料。
