Pretreatment of Municipal Wastewater by Enhanced Chemical
The efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. In the present investigation, the effect of Chemically Enhanced Primary Treatment (CEPT) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in Tehran, Iran.
In municipal wastewater treatment, anaerobic digestion is the slowest process requiring at least 15 day solids retention time (SRT). Treating only a small fraction of the total wastewater stream, anaerobic digesters require large reactor volumes and consistent heating (40°C).

Pretreatment of Municipal Wastewater by Enhanced Chemical Coagulation
Overview of pretreatment strategies for enhancing sewage
Sewage sludge management is now becoming a serious issue all over the world. Anaerobic digestion is a simple and well-studied process capable of biologically converting the chemical energy of sewage sludge into methane-rich biogas, as a carbon-neutral alternative to fossil fuels whilst destroying pathogens and removing odors.
However, in the case of employing polyaluminium chloride (PACl) coagulation and ozonation as a pretreatment, the extent of flux decline rates was enhanced up to 88 and 38%, respectively. In the CF–MF hybrid system, the removal efficiencies of COD and total phosphorus were significantly enhanced at a coagulant dose above 30 mg/L.

Challenges and an Implementation Framework for Sustainable
Due to its ability to recover both material and energy from organic waste, biogas technology is considered one of the best technology for treating organic waste. While in many emerging Asian countries more than 50% of municipal waste is organic waste, the amount of organic waste treated with biogas technology remains very limited. This study identified key challenges faced by practitioners in
1. Introduction. Dwindling water supplies and growing populations have made planned potable reuse an increasingly important component of water resource management for many urban areas around the world [1–3].Although reuse can only be a portion of a water supply portfolio due to intrinsic water losses, reuse of wastewater can augment the supply of water for agriculture, industry, and potable
Activated Sludge Technologies for Treating Wastewaters
Case studies are drawn from the pharma, food and shale gas industries. Based on short courses taught by the authors, as well as hundreds of hours of in-plant consulting, this book offers the tools to understand and modify the activated sludge process for superior and sustainable wastewater treatment.
