Increase biogas and biomass production with the Szego Mill.

Wastewater treatment plants can add the Szego Mill into their process flow for greater recovery of centrate, and to increase the biodigestion of activated waste sludge resulting in significantly higher methane production for plant powering.

The unique shearing action of the Mill’s rollers crushes the cellular membrane, releasing more water and allowing bacteria to better digest AWS. Better digestion also means a better quality solid biomass end-product, while the greater centrate release allows a dryer product for reduced additional drying costs.

Increased Biogas • Increased Centrate Recovery • Better Quality Biosolids • Reduced Polymer Costs • Reduced Waste Product

Enhance Wastewater Treatment With The Szego Mill

By using the Szego Mill in Wastewater Treatment Plant process flows, your Activated Waste Sludge becomes a superactive and much more easily digestible fine food for anaerobic bacteria. The Szego Mill breaks through the cell walls of biological matter in the AWS slurry, releasing the contents trapped in the cellular structure to ensure efficient and rapid operation of digesters.

When you improve the potential for complete anaerobic digestion you get increased biogas production, higher-quality biosolids, and significant cost savings. 
The combined mixing-grinding action of the Szego Mill allows you to add cheap organic waste, resulting in 250+% higher methane production.

Industrial waste additives such as ash can be ground and mixed in one step using the Szego Mill, to turn your regular biosolids into more valuable fertilizers.

See the following research papers below for more details on how to increase ROI in your wastewater treatment plant.

Enhancement of Methane Productivity of Anaerobic Reactors of Wastewater Treatment Plants

This paper was made available by our associates and is not authored by Szego Materials Engineering. We offer it to our customers for relevance to processes using the Szego Mill.

This paper describes technological possibilities to enhance methane production in the anaerobic stabilization of wastewater treatment plant excess sludge. This objective can be achieved by the addition of waste residues: crude glycerol from biodiesel production and residues from fishery. The addition of glycerol in an amount by weight of 2 – 5% causes enhancement of methane production of about 250 – 400%.

Anaerobic Co-Digestion Of Sewage Sludge With Fish Farming Waste

This paper was made available by our associates and is not authored by Szego Materials Engineering. We offer it to our customers for relevance to processes using the Szego Mill.

In recent years, much attention has been focused on the improvement of digester biogas production, in order to upgrade their role in stabilizing the sludge and also to produce a feasible bio-energy power plant. One option for improving methane yields is co-digestion. This process is well known and resulting in much higher methane yields when glycerol, food waste and similar types of organic waste were combined with sewage sludge.

Wastes from fish processing plants are an ideal co-substrate for the anaerobic digestion process. The main objective of this work was to evaluate the use of fish farming sludge as a co-substrate, in order to boost biogas production during the anaerobic treatment of sewage sludge. The effect of fish farming sludge supplementation on methane yield was examined in continuous experiments, and the fish farming sludge limiting concentration in the feed for a stable digestion process was estimated (the risk of organic overloading).

Generalised Integration Of Solid Waste Treatment Practices To Enhance Methane Productivity, Generate Suspension Fertiliser, And Upgrade Biogas

This paper was made available by our associates and is not authored by Szego Materials Engineering. We offer it to our customers for relevance to processes using the Szego Mill.

This paper presents a general solution of how to link together the treatment of different solid waste: excess sludge, wastes glycerol or fishery residues and waste ash. The aim of the solution is to enhance biogas production and to produce an organic–mineral suspension fertiliser. The enhancement of biogas productivity is achieved by adding waste glycerol from biofuel plants or fish residues from fish farming and fishing industries into anaerobic reactors of wastewater treatment plants. The enhancement of biogas productivity lies in the range of 200–400%.
