ACHIEVING
CLASS A TWO-STAGE THERMOPHILIC PROCESS TO TREAT BIOSOLIDS IN LOS ANGELES R.T. Haug, W.J. Hartnett, E.B. Ohanian, G.L. Hernandez, V.S. Abkian, W.A. Wert and J.E. Mundine Capital projects directly related to the Class A conversion total about $7.7 million. On the savings side, the plant expects to save about $600,000/year on reduced polymer and biosolids hauling costs. Part II |
