Effects of microalgal concentration and pH with flocculant on microfiltration [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2023 To make algal biomass a suitable feedstock for fuel and bioproducts, a practical way of dewatering and concentrating algal cells must be devised. In this study, a system comprising microfiltration membranes combined with a flocculant was developed on a ...

Physiologia Plantarum, Volume 173, Issue 2, Page 536-542, October 2021., 2021 Abstract Harvesting microalgae from liquid culture is a difficult issue to solve and is most commonly done through settling. However, settling is a slow process on its own and generally needs to be induced chemically or by introducing stress to the culture.

GCB Bioenergy, Volume 13, Issue 6, Page 914-940, June 2021., 2021 Studies on recycling of various streams for water and nutrient supply in microalgae cultivation are encouraging. However, presence and subsequent accumulation of organic and inorganic molecules produced during microalgae growth or generated during post‐processing can limit the long‐term recycling potential of these streams.

Tannins from cashew tree (Anacardium occidentale) bark as a flocculant for water clarification
Revista Ambiente & Água, 2022 Concern about the overexploitation of natural resources has increased in recent decades, especially involving water and its treatment. Paradoxically, one of the sources of water pollution is the treatment itself, due to the use of chemical flocculants ...

Biofuels, Bioproducts and Biorefining, Volume 14, Issue 6, Page 1270-1285, November/December 2020., 2020 Abstract It will be necessary to make efficient use of our resources if our society is to be converted into a bio‐based economy. Every year large side streams of bark are produced in sawmills and pulp mills. In addition to utilizing the bark for heat and electricity production, as happens today, high‐value chemical components could be extracted prior ...
