Nanonet trapping for effective removal of nanoplastics by iron coagulation Open
Nanoplastics (NPs) are emerging aqueous pollutants, posing risks to drinking water safety and human health. However, conventional coagulants, widely employed in water treatment plants globally, are ineffective at removing NPs. Here, we pre…

Understanding the risk of enhanced particle penetration into slow sand filter beds when using underwater skimming techniques Open
This study evaluated abiotic slow sand filters (SSFs) to understand the risk of particle penetration during underwater skimming (UWS), focusing on clogging, headloss development, and particle breakthrough. Pilot-scale filters containing cl…

Reducing environmental burden of electroplating wastewater treatment by ternary cooperation of zero-valence iron, manganese, and graphitic biochar Open
Iron-based technology is one of the most practical approaches to remove toxic metals from electroplating wastewater, but faces the problem of low efficiency and requires energy/chemical-demanding steps for safe disposal. Here we develop an…

Evaluating the impact of underwater skimming on slow sand filter performance and operation Open
Conventional cleaning of slow sand filters (SSFs) requires the beds to be drained before a layer of media and the Schmutzdecke are removed, called 'dry skimming' (DS), which can result in significant downtime. An alternative is proposed wh…

Predicting the impact of underwater skimming on dissolved oxygen consumption in slow sand filters for potable water treatment Open
In a well-functioning slow sand filter (SSF), dissolved oxygen (DO) is crucial for enabling aerobic processes and microbiota growth. Given that DO supply is predominantly via the feed water, flow pauses (e.g., during cleaning) may trigger …
