Evaluation of Solubilization with Thermal Hydrolysis Process of Municipal Biosolids
… sludge conditioning properties, the use of thermal hydrolysis process before anaerobic digestion has been adopted with an increase in solids destruction, COD removal, and methane gas. In this study, the evaluation of thermal hydrolysis process as a viable pretreatment strategy to anaerobic …

Development of an Integrated thermal hydrolysis process - Anaerobic Digestion (THPAD) Model
… anaerobic digestion is one of the most common processes used to treat sludge generated from wastewater treatment plant (WWTP) processes. However, with the exponential increase in populations, which implies an increase in WWTP loads, the amount of waste generated poses an imminent problem to the …

Impact of operating conditions on thermal hydrolysis pre-treated digestion return liquor
Return liquor from thermal hydrolysis process (THP) can significantly add to the nitrogen load of a wastewater treatment plant (WWTP) and introduce UV quenching substances to the wastewater stream when recycled. While there are mature technologies in place to handle the inorganic nitrogen produced …

Conventional and Advanced Thermal Hydrolysis in Sewage Sludge Pre-treatment
The thermal hydrolysis process (THP), a method that employs heat (at temperatures surpassing those of autoclaves, reaching up to 200 ℃) and pressure (reaching up to 25 bar) in the absence of oxygen, holds promise as a technology for pre-treating sludge before anaerobic digestion (AD) to enhance …

The Economic and Technical Feasibility of the Application of Partial Nitritation Anammox Technology Over Conventional Nitrification Denitrification for the Treatment of Sidestream Liquor at Cape Flats WWTP
… regional anaerobic digestion (AD) facility (Thermal Hydrolysis Process (THP)+AD) at Cape Flats WWTP in South Africa. The study focused on comparing a conventional nitrification denitrification (Modified Ludzack-Ettinger (MLE) configuration) with a novel partial nitritation/ anammox (PN/A) …

Effects of Thermal Hydrolysis Pre-Treatment on Anaerobic Digestion of Sludge
… readily degradable by anaerobic digestion. The thermal hydrolysis process has been used in several treatment plants around the world, but none currently operate in the US. Thermal hydrolysis causes cell walls to rupture under the effect of high temperature and high pressure and results in highly …
