    • Scaleable bacterial injection, aeration and filtration system to effectively control microbial community function of aquatic systems. The present invention is a substantially simplified system with respect to handling growth and dispersion of microorganisms in solution and is also adaptable to many different end-use applications, including treatment of ornamental fish and aquaculture, pond and streams and sewage treatment systems. Initial microorganism materials are provided in the form of aqueous suspensions, which are incorporated into a large volume of water in a vessel. Microorganisms are entrapped inside a carrier that serves as a physical enclosure for cell retention. It has a porous structure to facilitate the diffusion of substances, such as ammonia, nitrate, nutrients, fuels and organic carbon, into its internal void volume, where substrate reduction is accomplished by entrapped cells. Specific species of microbes are injected into a filtration matrix that is bathed in oxygenated effluent and a portion of which is dispensed into an aqueous environment. The apparatus can be electronic, air or fluid driven and injected with the desired microbial species, preferably multiple time per day. Multi-stage media can be placed into packed filter units of convenient sizes for wastewater regeneration as well as natural water pollution reduction. The reactor canisters containing entrapped cells are portable and can be assembled off-site and then delivered to the field for installation and immediate operation. Bio-solid reduction, odor reduction, unplugging of leaching fields, conversion and reduction of nitrogen species in natural waters such as lakes and ponds, etc. can be accomplished.
    • 可扩展的细菌注射,曝气和过滤系统,有效控制水生系统的微生物群落功能。 本发明是关于处理微生物在溶液中的生长和分散的基本简化的系统,并且也适用于许多不同的最终用途应用,包括观赏鱼和水产养殖,池塘和溪流以及污水处理系统的处理。 初始微生物材料以水性悬浮液的形式提供,其被并入容器中的大量水中。 微生物被捕获在用作细胞保留的物理外壳的载体内。 它具有多孔结构,以促进物质如氨,硝酸盐,营养物质,燃料和有机碳的扩散到其内部空隙体积中,其中底物还原通过包埋的细胞完成。 将特定种类的微生物注入过滤基质中,沐浴在含氧流出物中,其一部分被分配到水性环境中。 该设备可以是电子的,空气的或流体驱动的并且注入所需的微生物物种,优选每天多次。 多级介质可以放置在方便尺寸的包装过滤器中,用于废水再生以及天然水污染减少。 含有捕获的细胞的反应器罐是便携式的,可以非现场组装,然后输送到现场进行安装和立即操作。 可以实现生物固体减少,气味降低,浸出场的拔出,天然水如湖泊和池塘等中的氮物质的转化和还原。
