LAS removal across an institutional trickling filter

Abstract

Field studies with a low‐rate trickling filter have shown a paraffin‐derived LAS surfactant to be removed nearly as efficiently as the rest of the organics contained in an institutional sewage. A nondomestic cracked‐wax‐derived LAS surfactant, which was fed over a second two‐month period for reference purposes, was removed at a somewhat lower rate. These tests were conducted at the New Jersey Colony at New Lisbon during the period April to August, 1965.
