Electrocoagulation of Microalga Chlorella vulgaris.
Lucáková, Simona
This study is focused on harvesting of Chlorella vulgaris, well-known microalga with wide range of use in nutrition and health care. Harvesting (separation of cells from a culture medium) is an important part of the production process. It was estimated that approximately 30% of the production costs is the cost of biomass separation. Harvesting densities of photoautotrophic microalgae are relatively low (the final dry biomass concentrations usually vary in range 0.5–3 g/L). Centrifugation is the most frequently used method of harvesting, but it is economically inefficient due to its high process cost.

Monitoring system of hop harvest
Kořen, Jiří ; Ciniburk, Václav ; Podsedník, Jan ; Veselý, František
Metodika pro praxi prezentuje efektivní monitorovací systém sklizně chmele. Nasazení monitorovacího systému do sklizňové techniky přináší možnosti získávání důležitých podkladů pro zdokonalování organizace a zvyšování efektivnosti každého jednotlivého sklizňového střediska. Sklizňová technika doplněná o monitorovací systém bude snižovat dosavadní požadavky na praktickou zkušenost pracovníků, obsluhujících jednotlivé typy strojů.
