New legislation has highlighted the need for nutrients, such as phosphorous and ammonium in wastewater (WW) discharges to be reduced to protect our environment. The water treatment industry is currently heavily dependent on the use of chemicals to promote phosphate-precipitation into a sludge which must then be removed and disposed of. There has been a massive increase in demand for ferric (the most used common chemical option). Current forecasts predict there will be a 30% shortfall in supply of ferric by 2025\. Therefore, alternative nonchemical solutions for nutrient removal is of significant interest within the WW sector.Industrial-Phycology (I-Phyc) has developed a process based on the industrial application of microalgae for the sustainable and environmentally friendly treatment of WW. The I-Phyc process utilises the algal cell as a biocatalyst, which ensures fast and effect removal of phosphate, ammonium, and a wide range of emerging containments simultaneously. The I-Phyc process has been designed to be retrofitted onto small WW treatment works, removing the need chemicals.The use of the algal biomass and the quality of the treated water are critical to the process and are both dependent on the technology used to separate the algae from the water. However, this is known to be challenging due to the low biomass to liquid ratio, small cell sizes, and specific gravities very similar to that of the medium, creating a stable suspension. I-Phyc currently employs the best-known technology, centrifugation, to separate the algal material, however the technology is prohibitively expensive and represents ~30% of the total energy required for the whole I-Phyc process. It also requires significant and complex maintenance. Water operators are well known to be risk averse, therefore the separation technology selected must meet I-PHYC's requirements and be relatively well known in the water industry.I-Phyc has been screening several separation technologies, however each of technology has multiple variables that can be altered to affect the efficiency of separation making optimisation time consuming. Through the support of Innovate UK's 'A4I' competition I-Phyc will collaborate with TÜV SÜD National Engineering Laboratory (NEL) a world leading modelling facility. I-Phyc has previously worked with NEL and understands the impact modelling can have on the depth and speed of decision making. Working with leading experts to model and optimise the separation technologies would significantly reduce I-Phyc's capital and operational costs and increase the number of potential wastewater sites, which often have limited electrical capacity

新的立法强调了对养分的必要性，例如废水（WW）排放中的磷和铵，以减少以保护我们的环境。目前，水处理行业在很大程度上取决于使用化学物质将磷酸盐促进的污泥促进污泥，然后必须去除并处置。对铁的需求量大大增加（最常用的常见化学选择）。当前的预测预测，到2025年，铁的供应将有30％。因此，替代营养清除的非化学解决方案在WW部门中引起了重大兴趣。工业生物学（I-PHYC）基于微藻对WW的可持续和环境友好处理的工业应用开发了一个过程。 I-PHYC过程利用藻类细胞作为生物催化剂，可确保快速并有效去除磷酸盐，铵和广泛的新兴遏制。 I-PHYC工艺已被设计为改装到小型WW处理厂上，消除了需要化学物质。使用藻类生物量和处理过的水的质量对该过程至关重要，并且都取决于用于将藻类分开与水分开的技术。但是，由于液体比率低，小细胞大小和比培养基非常相似，因此众所周知，这是具有挑战性的，从而产生了稳定的悬浮液。 I-PHYC目前采用最著名的技术离心材料来分开藻类材料，但是该技术的昂贵，占整个I-PHYC过程所需的总能量的约30％。它还需要大量且复杂的维护。众所周知，水经营者是避开风险的，因此所选的分离技术必须满足I-PHYC的要求，并且在水行业中相对众所周知。-Phyc一直在筛选几种分离技术，但是每个技术都有多个可以改变的变量，以影响分离效率的分离效率。通过Innovate UK的“ A4I”竞赛的支持，I-PHYC将与TüvSüd国家工程实验室（NEL）合作世界领先的建模设施。 I-PHYC以前曾与NEL合作，并了解建模对决策的深度和速度可能产生影响。与领先的专家合作建模和优化分离技术将大大降低I-Phyc的资本和运营成本，并增加潜在的废水站点的数量，而潜在的废水站点的数量通常有限
