World Environment Day is the UN's most important day for encouraging worldwide awareness and action for the protection of our environment. Since it began in 1974, it has grown to become a global platform for public outreach that is widely celebrated in over 100 countries. Each World Environment Day is organized around a theme that [...]
SEDOSR Engineering S.L. has been included in the Register of Innovate SMEs by the Ministry of Economy, Industry and Competitiveness of the Government of Spain. To be an integral part of such register small and medium enterprises must meet one of the following requirements: • Having received public funding for an R+D+i project • Have [...]
While the Archimedes screw pump was being improved, another work-team developed the separator that will work with it. Both will be connected and will rotate together and will consent water separation (heavy phase) before pump suction. A design challenge never made until now. Our prototype was made in stainless steel following high quality standards that [...]
Once the new parts were made we could simulate working conditions, actual adjustmen between parts and ready a more robust prototype than the previous one whose body was completely made of sintered powders of nylon. The test bench confirmed the first tests results and helped us to know better the limits of each [...]
Once we've verified the design of the screw, we're starting its production in stainless steel. Due to its geometry and its perfect fitting with the sealing disc it's the most complicated part of the pump. Nevertheless we're confident of achieving the goal!. After quite a few attempts and difficult adjustment and setting of various machine [...]
Once the idea was developed, to build a skimmer equipped with a Archimedes screw pump but able to separate part of the recovered water, we start manufacturing of the prototype. Although our final aim is to manufacture a robust pump capable of working with any type of fluid, and being stainless steel the material that [...]
Analyzing performance and design of the available pumps we are inclined to use screw pumps in our aim to reduce water content in the skimmer. Its geometry and the way in which power transmission takes place makes us think that they are the most suitable to work together with a centrifugal separator. Now is [...]
In order to find a solution to the problem of the huge amount of water recovered together with the spilled hydrocarbons we need to know how these are pumped from the skimmers, because their knowledge will help us to find the best way to integrate the industrial separation methods presented in the previous post. Once [...]
In this post we will present different methods of oil/water separation and will analyze feasibility of using them to improve the efficiency of skimmers and pumping units. Gravity Differential Separation: The oldest and more extended separation method. It’s usually the first step in the treatment of oily water. Ruled by the Stokes' law is based [...]
The goal has been focused: We need to increase the efficiency of skimmers and improve the energy balance of decontamination operations. We could analyze step by step response operations up to final treatment trying to adopt better techniques and integrating low consumption motorizations, we will, but there is a job we can do before and [...]
