Sewage treatment plant-case study
Contributing to snowy regions in which the transportation of sludge is difficult In municipal wastewater treatment plant in snowy regions, snow-bound in winter, taking dewatered cake out regularly is sometimes difficult. Two problems were also presented in this municipal wastewater treatment plant, i.e., the difficulty of taking sludge out using carriers in winter, which had been anticipated ...

A Deep Dive into Open Scroll Decanter Centrifuge Design
Wastewater treatment facilities looking for savings frequently focus on creating a drier dewatered cake, reducing polymer consumption, and using less energy. A decanter centrifuge accomplishes all of these, primarily because it is more efficient than a settling pond, acting on solids with several times the force of gravity. The result is greater separation power and speed, more solids, and a ...

Phosphorus partitioning in co-dewatering biosolids and water treatment residuals
Stabilization and dewatering methods for wastewater solids determine the concentration and nature of phosphorus (P) in biosolids and in-plant sidestreams recycled to the liquid treatment facility. Because water treatment residuals (WTR) exhibit strong immobilization of soluble P, this study evaluated the impact of co-dewatering WTR and biosolids on the P partitioning during dewatering and the ...

A combined reed bed/freezing bed technology for septage treatment and reuse in cold climate regions
A combined reed bed-freezing bed (RB-FB) technology was effective at treating septage under Canadian climatic conditions over a 5-year period with average loading rates of 82–104 kg TS/m2/y. Varying hydraulic and solid loading rates as well as the increasing sludge cake with time had little to no effect on treatment efficiency, with almost complete removal of organic matter, solids, heavy ...

Corrugated Sheet Plant
The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50/batch. The operator stated that they had low solids, they tended to overdose which ...

Key issues to consider when using alum sludge as substrate in constructed wetland
Globally, alum sludge is an easily, locally and largely available by-product from water treatment plants where aluminium sulphate is used as the coagulant for raw water purification. Owing to the high content of Al ions (29.7 ± 13.3% dry weight) in alum sludge and the strong affinity of Al ions to adsorb various pollutants especially phosphorus (P), alum sludge (in the form of ...

Geotube Dewatering Technology Helps Arizona Chemical Dewatering Technology Helps Arizona Chemical Solve “Tight Space” Challenge - Case Study
Arizona Chemical Company, a Division of International Paper, converts terpenes, generated by cooking wood pulp for making paper, into resins used to make adhesrves. The plant's process waste of inorganic compounds (magnesium hydroxide, crude tall oil and fatty acids) is sent to an equalization basin (EQ) for storage and settling. The supematantis discharged into Panama City's wastewater treatment ...

Screw Press Machine in Biogas Slurry Dewatering
Biogas production is a sustainable and environmentally friendly way to generate energy from organic waste. However, the process generates a byproduct called biogas slurry, which is rich in nutrients but also high in water content. Managing this slurry efficiently is crucial for reducing transportation costs, controlling odors, and maximizing the benefits of nutrient-rich byproducts. In this ...

A case study of the sludge thickener - Office Building
Costs for industrial waste reduced with sludge thickener Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to ...

Beijing - Gao Bei Dian Water Reclamation Plant - Case Study
Client: Beijing Drainage Group Solution: CambiTHP - B12 On 1st September 2014, Cambi was awarded the initial Beijing project, Gao Bei Dian, from Beijing Drainage Construction Company, a flagship for large-scale sludge projects with Cambi Thermal Hydrolysis Process (Cambi THP). The project finished in December 2016. The full sludge amount 99,100 tDS/y be treated in Cambi THP with subsequent ...

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 ...

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 ...

Land application of sewage sludge (biosolids) in Australia: risks to the environment and food crops
Australia is a large exporter of agricultural products, with producers responsible for a range of quality assurance programs to ensure that food crops are free from various contaminants of detriment to human health. Large volumes of treated sewage sludge (biosolids), although low by world standards, are increasingly being recycled to land, primarily to replace plant nutrients and to improve soil ...

Environmental sludge treatment
During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

Geotube Containment and Dewatering technology was used to dispose of slurry waste from North River Mine - Case Study
At the North River Mine in Berry, AL, two waste streams are created from the processing plant, coarse rock and fine rock particles. Coming from the processing plant, the fine rock particles are suspended in water forming a slurry. This slurry is normally disposed of via surface impoundments or injected into abandoned underground mine workings. The volume of this waste stream is very significant ...

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 ...
