Amorphous metal hydroxides are known as "floc". This fraction of the floc is called "return activated sludge" (R.A.S.). Settled floc is returned to the mixing basin to continue growing in primary effluent. Therefore, flocculants are often added to induce floc precipitation for easy filtration. In these plants, a biotic floc is created which provides the required substrate. The word "floc" comes from the Occitan language and means bouquet of flowers. The word comes from the Aromanian "floc", from Latin "floccus". Thus far, Reynolds CEO Susan Ivey has refused to meet with FLOC representatives. Within a few weeks, 21 other growers had agreed to contracts with FLOC as well. In the fall of 1985, Campbell's officials agreed to negotiate with FLOC. FLOC initiated a boycott of Campbell's. In 1993, FLOC president Velasquez expressed doubt that his members would approve a merger. So that year 2,000 FLOC members walked off their jobs in Ohio. It also produces the floc de Gascogne, with delicate floral accents.
