The effect of iron and aluminium for phosphorus removal on anaerobic digestion and organic sulfur generation
The addition of iron or aluminium into activated sludge basins for phosphorus removal is likely to impact both the efficiency of the anaerobic digestion process and the generation of odor-causing compounds following digestion and dewatering. In this study, the impact of iron and aluminium addition on digestion and odor-causing compounds was investigated by using batch digestion of combined ...

Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment
Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these ...

Extension of ASM3 for two-step nitrification and denitrification and its calibration and validation with batch tests and pilot scale data. Water Research
Abstract: Although traditionally not taken into account by most of activated sludge models the production of nitrite as an intermediate of the nitrification–denitrification processes becomes of interest in some specific plant operational situations or in case of high sensi- tivity of the receiving ecosystems. The Activated Sludge Model No.3 (ASM3) was therefore extended for two-step ...

Dynatec Provides MBR System for Hazardous Landfill
The Problem A hazardous waste landfill in Belleville, MI, owned by the Environmental Quality Company had a problem. They needed to develop a treatment process to remove COD, high TDS, heavy metals, phenol, PCB’s, Ammonia, and Molybdenum from the landfill leachate. Current treatment comprised of chlorination and activated carbon treatment was very costly. Evaluation The treatment process ...

A New, Cost-Efficient Way to De-sludge your Lagoon
Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes. If the town’s ...
