We introduce tycho\u2010filtration based on self\u2010settling algae aggregates, a biotechnology to extract excess of N and P from hypertrophic waters. This technical note has the following four scopes: (i) explaining the operating principle of tycho\u2010reactors, (ii) drawing attention to parameters that may influence performance, (iii) identifying strategies for containing nuisance organisms in tycho\u2010reactors, and (iv) discussing potential applications of this technology.

This biomass consisted of 55% desmid Chlorophyceae and 44.8% diatoms vol:vol, carrying \u22484.16% N and \u22480.43% P per DW. Biological interferences requiring specific management include surface\u2010attached filamentous algae, toxin\u2010producing cyanobacteria, and the algae\u2010eating bladder snail (\n                    <jats:italic>Physella acuta<\/jats:italic>\n                    ). Advantages of tycho\u2010filtration are predicted to come from photosynthesis being reliant on solar light, low cost of algae harvesting, potential for automation, and suitability for solar\u2010based water flow. Potential applications of this technology include preventing severe algal blooms in small lakes, control of N in recirculated aquaculture, and detrophication of liquid effluents from aquafarms that threaten downstream ecosystems.\n                  <\/jats:p>","DOI":"10.1002\/jeq2.70093","type":"journal-article","created":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T10:49:37Z","timestamp":1761216577000},"page":"2074-2083","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Introduction to tycho\u2010filtration\u2014A biotechnology for lacustrine detrophication"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0095-3082","authenticated-orcid":false,"given":"Radu","family":"Popa","sequence":"first","affiliation":[{"name":"National University  Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4633-8480","authenticated-orcid":false,"given":"Ioana Corina","family":"Moga","sequence":"additional","affiliation":[{"name":"DFR Systems S.R.L.
