Enviro-Neptune works in the research, development and improvement of technologies dedicated to commercial, institutional and community applications in decentralized sanitation. When it comes to our aquatic environments, phosphate removal is being investigated due to its significant environmental impact. The majority of our modern agriculture is mainly dependent on Phosphorus (P) derived from phosphate rock, which is a non-renewable resource. There is the necessity for recovery of phosphate as a resource for sustainable food production. Activated Alumina (AA) is an inorganic porous material, semi-crystalline and essentially comprised by aluminum oxide with a number of unique characteristics that make it a good candidate for many diverse applications.The proposed collaborative project Lambton College and Enviro-Neptune will focus on understanding the mechanisms of desorption of P in saturated AA, determining the level of desorption of P in saturated AA, and determining the percentage of recovery of P. Overall, the purpose of the present study is to evaluate the potential for a more effective desorption process to regenerate AA saturated in P for both high and low concentration scenarios and determine the percentage of recovery of this valuable source. The success of the research will lead to the integration of this new technology and will provide Enviro-Neptune with a competitive price advantage in the market since the company's operating and maintenance costs will drop. In addition, this will help to avoid waste management and landfill cost that it is approximately $128,000/year. Furthermore, any contributions with phosphorous recovered with AA will be economically beneficial for Canada by saving money on P imports.

Enviro-Neptune 致力于研究、开发和改进致力于分散式卫生设施商业、机构和社区应用的技术。当谈到我们的水生环境时，由于其对环境的重大影响，磷酸盐的去除正在受到研究。我们现代农业的大部分主要依赖于从磷矿中提取的磷（P），这是一种不可再生资源。有必要回收磷酸盐作为可持续粮食生产的资源。活性氧化铝 (AA) 是一种无机多孔材料，半结晶，主要由氧化铝组成，具有许多独特的特性，使其成为许多不同应用的良好候选者。兰姆顿学院和 Enviro-Neptune 拟议的合作项目将重点关注了解饱和 AA 中 P 的解吸机制，确定饱和 AA 中 P 的解吸水平，并确定 P 的回收百分比。总体而言，本研究的目的是评估更有效的解吸过程的潜力到在高浓度和低浓度情况下再生磷中饱和的 AA，并确定这一宝贵来源的回收百分比。研究的成功将导致这项新技术的整合，并将为Enviro-Neptune提供市场竞争价格优势，因为该公司的运营和维护成本将会下降。此外，这将有助于避免每年约 128,000 美元的废物管理和垃圾填埋成本。此外，通过 AA 回收磷的任何贡献都将通过节省磷进口费用而为加拿大带来经济利益。
