Treating Liquors from Enhanced Digestion Facilities; Start-up, Commissioning and Optimization of a SHARON LTP at Whitlingham STC

Abstract

The increasing use of enhanced digestion of biosolids has led to an increasing demand for treatment solutions of high strength nitrogen and phosphorus rich return liquors arising from enhanced digestion. Sustainable, capital and energy efficient treatment solutions for these liquors are an important part of successful implementation of enhanced digestion processes. This paper outlines the selection, start-up, commissioning and optimization of a SHARON (Stable High Ammonia Removal Over Nitrite) Liquor Treatment Plant (LTP) at Whitlingham Sludge Treatment Centre (STC) where a CAMBI thermal hydrolysis enhanced digestion stream has recently been installed.
