Sednove´s consumer products have been excellent and pioneerinig solutions for problems concerning freezing water pipes and aeration of well water since the beginning of 21st century. Now this product line has been moved under the brand name AkvaSolina.
Sednove ejector cell – solutions for green technology
Sednove celluralized ejectors provide effective physical method for mixing fluids, gases or vapors. The applications can be found in aquaculture as well as biochemical and petrochemical industries.
Easy to scale
Ejector cell-based processing methods accelerate reaction times of several processes. This is based on a vacuum where micro-sized gas bubbles and droplets form a larger reaction area. The aero and hydrodynamic properties of the process are customizable to the application and the capacity is also easily scalable from laboratory conditions to industrial scale.
Proper selection of materials enables the usage of ejectors in high temperatures and with aggressive media. Moreover several different materials are available for the food contact application.
Thesis on the use of an ejector cell
Sednove Ejector Cell
Title of Thesis: Optimization of activated sludge aeration process using an ejector cell
Author: Helmi Hellsten, Bachelor of Engineering, Environmental Engineering, SAVONIA
Main point:
– Most of the energy consumption in a wastewater treatment plant is used for aeration. (55% ref. Motiva 2018)
– From the results it was learnt that the ability of the ejector to aerate potable water is similar to other diffuser aerators. (i.e. at least as good or better)
– Advantages of ejector -based aeration:
No additional energy is consumed for gas intake or mixing, as the ejector operates using the kinetic energy of the water, which is obtained by pumping the water. In addition to energy savings, almost the entire side flow is mixed and utilized, and the mass transfer coefficient of the gas phase remains high. Reference Martin and Williams 2009, page 296.
