Wastewater treatment: how to prevent sludge settling in digesters
In municipal wastewater treatment plants, where large quantities of wastewater are treated and purified every day, anaerobic digestion is a key process for the sustainable reuse of stabilised sludge and its valorisation for energy purposes. In fact, anaerobic sludge digestion helps large wastewater treatment plants to: Stabilise the sludge and further reduce the pollutant load Valorise the ...

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 ...

Blending anaerobic co-digestates: synergism and economics
Co-digestion is the process in which wastes from various sources are treated together. Therefore, more organic carbon is added to make efficient use of existing digesters. The objectives of this study were to compare potential co-digestates, determine synergistic and antagonistic co-digestion outcomes and estimate economic benefits for preliminary screening. Over 80 wastes were identified from 54 ...

A 600T/D sludge thermal drying project case from Chongqing in China
It is proposed to build a sludge thermal drying plant in the reserved land for a power plant in Chongqing. The project construction is divided into three phases. The scale of the first phase is 600 t/d (moisture content 80%). Considering the fluctuation range of sludge moisture content (75%-82%), the maximum solid flux of treatment is 150 t DS/d. 1.Sludge components Table 1 shows the average mud ...

V-Bank Transition (VTS) - Robert O. Pickard Environmental Centre, Ottawa, Canada - Case Study
THE PROBLEM: The RobertO. Pickard Environmental Centre (ROPEC) in Ottawa, Canada was undergoing needed upgrades and expansions to its thickening and dewatering building. This building plays a vital role by in water treatment providing sewage receiving and pumping, sludge mixing and thickening, as well as dewatering digested biosolids. These processes release H2S, Ammonia, and other VOC's into ...

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 ...

How Will You Get Pyrolysis Machines That Can Process Oil Sludge?
There are many different materials that can be sent through a pyrolysis machine in order to make reusable products. As an example, if you utilize plastic, this will convert the plastic into charcoal, biofuels, and oil that can be used to lubricate different industrial machines. You can find the ones that work with precisely what is called oil sludge. Here is the sludge that is leftover from the ...

Wastewater-Primary Treatment
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

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 ...
