<p>Wastewater (4) treatment to increase effluent volatile fatty acid content consisting of providing wastewater to a primary treatment vessel (10) and adding a select quantity of an aluminum or iron salt (8), to the wastewater to enhance separation of organic matter. Separated organic matter is removed fr om the chemically treated wastewater forming a primary sludge and a primary effluent. Some primary sludge is fermented to form a volatile fatty acid ric h liquor (14) which may then be combined with the primary effluent and directe d to a bioreactor (18), thereby forming a volatile fatty acid enriched bioreactor feed.</p> |
