Drinking water biofilters have the potential to be fully sustainable and low-cost solutions to provide safe drinking water, particularly in developing countries. However, this technology still lacks the reliability and efficiency required to be widely employed, particularly for the targeted removal of specific contaminants such as pesticides. Indeed, yet unknown are the forces that control the composition and the activity of the microbial communities developing on the filter medium, which are responsible for the water treatment, impeding its full optimisation. Currently, the engineering of these systems is based on a fully empirical approach. If we want to upgrade this technology, we need a rational approach able to control the structure of the microbial community in the drinking water filters, using specific operational conditions. The overarching aim of this research is to develop eco-engineered filters for the removal of targeted pesticides using a combination of adsorption and biodegradation processes.

饮用水生物过滤器有潜力成为提供安全饮用水的完全可持续和低成本解决方案，特别是在发展中国家。然而，这项技术仍然缺乏广泛应用所需的可靠性和效率，特别是在针对特定污染物（如农药）的去除方面。实际上，控制过滤介质上微生物群落的组成和活动的力量是未知的，它们负责水处理，阻碍其充分优化。目前，这些系统的工程是基于一个完全经验的方法。如果我们想要升级这项技术，我们需要一种合理的方法，能够控制饮用水过滤器中微生物群落的结构，利用特定的操作条件。本研究的总体目标是开发生态工程过滤器，利用吸附和生物降解过程的结合去除目标农药。
