Sludge reduction treatment in urban sewage treatment plant
Sludge is the sediment produced by wastewater treatment, including solid particles, such as sludge, sand, fiber, animal and plant residues and their solidified flakes, various colloids, adsorbed organic matter and metal elements, microorganisms, bacteria, insect eggs, weed seeds and other solids embedded in wastewater. The sewage sludge of the municipal sewage treatment plant is mainly composed ...

What is Sludge Dewatering?
What Is Sludge vs. Sludge Cake? Sludge dewatering is a process in which a sludge slurry (sludge) is made more solid by removing water from its contents to form a sludge cake. A wide variety of municipal and industrial processes will create sludge cake after it is dewatered using various presses to form higher solids content versus a watery sludge slurry. While dewatering does not in itself treat ...

One of Europe’s largest wastewater plants handles 2 million challenges a day. What are yours? - Case Study
In Ambarli, Turkey, more than two million people depend on the capabilities of just one wastewater treatment plant. But as strict new environmental regulations came into effect, the city’s outdated facilities became unsustainable. To meet new demands, the new facility would need to treat 400,000 cubic meters of sewage per day within a very compact building. Technologies, costs, and ...

Simulation of sludge dewatering on belt filters
A mathematical model for belt filters was developed to determine optimum load rate and belt speed during drainage of flocculated biological sludge. Numerical simulations were performed for belt filters with and without plows, and the model fit experimental data well. Experiments showed that highly compressible cakes were formed during drainage, which was important. Due to cake compression, the ...

Floccin for Metals Removal Beats Hydroxide Precipitation Hands Down
The traditional approach for metals removal is Hydroxide Precipitation where the solubility for the metals changes to insoluble (precipitation) in the form of a metal Hydroxide as the pH increases. The common pH range for this is between 10-11 pH depending on the metal. Lime (calcium hydroxide or CAOH2), caustic (sodium hydroxide or NAOH) or magnesium hydroxide (MgOH2) are generally the chemicals ...

Wyeth - Case Study
Paddle Dryer turns waste into income for food processing plant. A northeast food processor turns its activated biological sludge waste from its manufacturing process into income by recycling the waste as an ingredient for organic fertilizer. When the state banned landfilling of the biological waste, a study was conducted that showed the waste contained enough nutrients to be considered a ...

Cutting Costs with ELODE Sludge Dewatering
Effectively dewatering wastewater sludge has traditionally involved belt presses, rotary fan presses, screw presses and centrifuge. However, these technologies can only remove water to a limited extent. The ELODE sludge dewatering system is an effective solution that separates solid and liquid components for easier disposal. Its compact design installs easily into a facility’s dewatering ...

Frequently Asked Questions and Troubleshooting in Activated Sludge Process (Part 3)
Q: What indicators can be detected for the microbiological ratio? And how can it be measured? Answer: The microfood ratio refers to the ratio of the organic matter content to the activated sludge concentration in the biochemical system before entering the biochemical system. Through this ratio, the load can be judged and the operation can be adjusted to avoid sludge aging and overage as well as ...
