Anaerobic digestionAnaerobic digestion requires temperature equalization and proper homogenization of the biomass to achieve a high gas production and to avoid sedimentation of organic matters. The surface crusts must be broken and prevention of foam must be managed if there are foaming tendencies. Sulzer can provide efficient and reliable Scaba agitators for digesters with high-efficiency propellers. Muffin Monster™ grinders upstream from the anaerobic digesters condition the sludge before digestion, improving the homogenization of the biomass and protecting the equipment downstream.
Chemical mixing - sludgeSometimes it is necessary to mix chemicals into the activated sludge before it enters the secondary sedimentation tank. For example, chemicals may be used to perform phosphorous removal on the effluent from the biological process. Many plants use chemicals to improve sludge thickening just prior to the sludge buffer tank.
Chemical mixing sewageChemicals must sometimes be mixed into the activated sludge before it enters the secondary sedimentation tank. Whenever this done, it is important to achieve an even distribution of the chemicals. Chemicals may be added to perform the chemical removal of phosphorous on effluent from the biological process. In other circumstances, chemicals such as cationic polyelectrolytes with a high molecular weight may be added to improve the quality and settling ability of flocs formed in the activated sludge process.

Sludge buffer tankThe sludge buffer tank can be used for a variety of purposes. The most common application is the blending and homogenization of highly concentrated primary, secondary or digested sludge. The solution used to mix the sludge itself, or to mix the sludge with the dosed thickening chemicals, depends on the design and volume of the sludge buffer tank. Submersible mixer types ABS XRW and RW, as well as the agitator type Scaba, can be used to provide highly efficient mixing. Positive displacement, progressing cavity transfer pumps and Muffin Monster™ grinders are used for solids reduction and sludge transfer from sludge feed to sludge dewatering process.
Tertiary treatmentTreated wastewater may occasionally require further treatment. Local discharge rules may pose strict limits that cannot be fulfilled by even the most effective process, or a higher quality of effluent may be requested for its reuse. When tertiary treatment is needed, various levels of filtration can be applied, including very fine filtration. Often, however, a final step of mixing and aeration is sufficient to achieve the target. When this is the case, Sulzer's submersible mixer types ABS XRW and RW can be used, along with submersible aerator type ABS TA–TAK and disc diffuser system types ABS PIK, DS and Sucoflow.
Case studies and articles
Scaba agitator for demanding industrial mixing applicationBallarat is a city located at the Yarrowee River in the Central Highlands of Victoria, Australia, with around 101’600 inhabitants. The Ballarat South Wastewater Treatment Plant (BSWWTP) has undergone an AUD 10 million upgrade. A new aeration system was also completed as part of this upgrade and it has helped optimize biological nutrient removal and reduce energy consumption.
Reliable Scaba agitators for demanding process applicationsIn 2010, the world’s largest single pulp line with a capacity of 5’000 t/d started in Rizhao. Its wastewater treatment plant was designed and built by Aquaflow (Veolia), and the plant currently operates with an even smaller environmental impact than what the tough Chinese regulations prescribe. To fulfill various applications in the process, Sulzer supplied reliable agitators which minimize both power and chemical consumption.
Vienna’s climate-neutral wastewater treatment plant gets efficiency boost with Sulzer technologiesThe E_OS (Energy Optimization through Sludge Treatment) project on the edge of Vienna is a pioneering facility designed to transform the Austrian capital’s wastewater treatment plant from a major energy consumer into a net producer. Important parts of the project therefore include maximizing energy efficiency and optimizing power generation.
Scaba heavy-duty agitators save energy in sulphur meltersPhosAgro is the biggest manufacturer of phosphate-based fertilizers in Europe. The largest site is the chemical cluster in Cherepovets, Russia, where the sulphuric acid is locally produced from elementary sulphur. Two new melters were built in an expansion project. It was essential to manage the heat transfer in the melters by agitators to ensure the capacity of the plant.
Optimizing the performance of sludge treatment and anaerobic digestion plantsLarge wastewater treatment facilities often incorporate an anaerobic digestion (AD) plant to handle sludge and deliver heat as well as electrical energy to support the operation of the site. Process performance depends on equipment reliability and getting the most out of the feedstock. Improved efficiency enables plants to increase throughput without expanding the site and this can be achieved by optimizing the sludge handling equipment.
How to optimize agitatorsSulfuric acid is the key chemical used in the production process of wet phosphoric acid (WPA). Hence, the production of sulfuric acid close to the phosphoric acid plant (PAP) has many advantages. Not only does this reduce transport costs, but the nearby production of sulfuric acid, which is an exothermal process, allows the residual thermal energy to be used for the manufacture of concentrated phosphoric acid. Steam is generated to feed the heat exchanger located within the concentration unit of the phosphoric plant. Read the whole article.
