Foam Filtration
All the pieces needed for a fully operation foam filtration system are finally coming together. A working compound pulley system with an ideal mechanical advantage of 14:1 has been constructed on-top of an aluminum support system that can be inserted onto a 55 gallon HDPE drum. The disk used for compression is made of HDPE. During testing of the system without water, the foam was demonstrated to compress up to 50% of its original volume with decompression taking place immediately after the completion of compression. A fitting was also successfully spin-welded onto the side of the drum to drain wash water during compression with several more planned at various heights. There is a possibility of replacing the bulk head valve with a spin-welded fitting onto the bottom side of the drum. This would give us a huge advantage in being able to set the drum on the ground instead of elevating it and building a frame to stabilize it. Several challenges remain including building a frame for stability and the stock tanks as well as attachment of the LFOM and chemical doser. Completion and testing of the system is planned in the following weeks with the goal of shipping it down to Honduras sometime this summer.
