Yes. Actually, I was the first consultant who designed the 'Namgis facility. I designed three different biofilter systems: the fluidized sand bed, the moving bed bioreactor, and the microbead filter.
The cheapest was the microbead filter. But unfortunately with the 'Namgis, politics got into it, and Tides Canada and Save Our Salmon and whatever are funded by fairly large organizations like the Gordon and Betty Moore Foundation, and Tides Canada has gone into partnership with the Freshwater Institute so they decided to use their technology.
The difference is that they were going to use the fluidized sand bed and now they're going to do the microbead biofilter. Their project is going to produce a little over 300 tonnes a year for $7 million. I'm going to produce 1,000 tonnes for $8.5 million. I'm going to use half the power. So I just have to shake my head.
