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、开发和改进专门用于分散式卫生设施的商业、机构和社区应用的技术。当涉及到我们的水生环境时，由于其对环境的重大影响，磷酸盐的去除正在进行研究。我国大部分现代农业主要依赖于磷矿石中的磷（P），磷矿石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，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。拟议的合作项目兰顿学院和Enviro-Neptune将侧重于了解饱和AA中磷的解吸机制，确定饱和AA中磷的解吸水平，总的来说，本研究的目的是评估一个更有效的解吸过程再生AA饱和的P的高浓度和低浓度的情况下，并确定回收的百分比，这一宝贵的来源的潜力。研究的成功将导致这项新技术的整合，并将为Enviro-Neptune提供市场上具有竞争力的价格优势，因为该公司的运营和维护成本将下降。此外，这将有助于避免废物管理和填埋成本，每年约为128，000美元。此外，与AA回收磷的任何贡献将是加拿大的经济利益，节省了磷进口的钱。
