Poultry further processor Keystone Foods, Reidsville, North Carolina, uses a rotary press to add value to wastewater by-product by reducing moisture and thus transportation costs.
The Keystone Foods facility ships dissolved air flotation by-products to a vendor for composting to make organic soil amendments. By reducing the moisture content of the by-product, shipping costs (and net energy usage) are reduced.
The rotary press reduces total solids from around 90 percent to under 35 percent.
