INL - Grinder Water Circulation and Filtering System

Idaho National Laboratory (INL) has reached out to the University of Idaho to completely re-design and test a water filtration system that is to be used in a hot-cell environment. Our team is working closely with the staff here at U of I and with INL to ensure that develop a system that meets all of the specific requirements. We will be updating the information on this page monthly until it is finalized in May of 2018, where we will then hope to share the success of our project.

Problem Statement
The current INL hot cell grinder filtration system does not efficiently remove particle build up in the water storage tank making it harder to clean and creates clogging of the pipes.

Mission Statement
To completely re-design and build a working prototype for the INL hot cell grinder filtration system to meet the client’s specifications. We will design a system where the collection of muck in the water tank is minimized, create a more efficient flow in the filtration system, and apply a cheaper filter and pump to the system. We strive to provide the best possible product to our client.

INITIAL DESIGN

This is the final integration design with all the placing of the components. The design is incomplete as it does not have finalized fittings on the pump or the filter to hold them in place. However, this design is elegant, easy to manufacture, and completes all the design tasks we need to reach the client’s needs. This design places the filer before the pump, much like the other designs, but does not have the bypass going into the filter. The filer will run completely gravity fed into a slanted tank as opposed to the flat tank of the other designs. The pump is places on the other end of the table at the end of the tank and pumps out into minimal tubing which allows for lower head loss. There is a T-joint at the maximum height constraint that allows for two values to be places on the ends of the T-joint. These values are for controlling the flow onto the grinder and creating a bypass tube for excess flow from the pump. This design is what we decided to be the best design to pursue moving forward.
