Treatment Process for Wastewater. Before wastewater can be disposed of, it must undergo thorough treatment. This is true for any type of wastewater, including water supplies used in residential, commercial, and industrial settings. When wastewater is collected via sewers, it is delivered to plants for treatment and disposal.Various sludge disintegration technologies for sludge minimization are discussed, including mechanical methods (focusing on stirred ball-mill, high-pressure homogenizer, ultrasonic disintegrator), chemical methods (focusing on the use of ozone), physical methods (focusing on thermal and thermal/chemical hydrolysis) and biological methods ...

In addition, the ball-mill method solubilizes sludge by agitating a ball with a diameter of 0.25–0.35 mm at a speed of 6–10 m/s. Examples of chemical solubilization are oxidation treatment and alkali treatment using KOH, NaOH, Mg(OH) 2, and Ca(OH) 2 [ 16 ].gration of bacteria cell walls in wastewater sludge using an agitator ball mill coupled with the use of the released carbon as an external carbon source for cell synthesis in biological denitrification was investigated as methods to reduce sludge production in Germany (Kunz et al, 1996). Sludge production

Thus, the waste-water pH is in range of 8.5 to 13.5. This waste­water consists of suspended solids in the range of 200 to 600 mg/l. BOD varies from 475 to 2400 mg/l and the COD is between 1100-3800 mg/l. The oil and grease is within a range of 32-150 mg/l. The phenolic concentration of this waste-water is 12.5 mg/l. 2. Waste-Water from Resin ...A process for resolving even tightly emulsified oil, water and solid emulsions by the application of a sheer force sufficient to break the emulsion. In one particular application, a tank bottom sludge produced in the petroleum industry is treated with the shear force of a bal or roller mill into the emulsion is broken. Simultaneous reduction in the particle size of the solids occurs.

liquefL solids as much as possible. Different disintegrating devices, mechanical as stirred ball mills, homogenizers, ultra-sound and other systems can be introduced in sludge treatment technology line after thickening of waste activated sludge, even can be directly integrated into thickening machine (lysate centrifuge). (Dohanyos at al., 1997)Wastewater Grinders - Franklin Miller. Franklinmiller Franklin Miller grinders reduce a wide variety of materials including sanitary wipes, rags, wood, paper, shoes, sludge and more. These units are proven to reduce pump clogging, protect process and dewatering equipment, reduce solids and keep wastewater systems running properly.

The sludge was dried at 105 °C, and then pulverized with a ball mill. After transferring the sludge powder into a tube furnace, air was evacuated from the tube by purging N 2 (flowing rate 15 L/h). Then the powder was calcined under N 2 atmosphere at 600 or 800 °C for 2 h (heating rate 10 ° …sludge production while retaining the effluent quality criteria. Therefore, efforts have been undertaken to reduce the excess sludge production in the activated sludge process. In the present work disintegration employing stirred ball milling (SBM) is added as an operational unit …

The sludge was ground using a ball mill, resulting in the production of a powder with a very fine grain size, which means that it had a large specific surface. This ensures a high pozzolanic activity, as explained by the creation of a larger surface area available for reaction.result of reduced production of sludge and/or disintegration processes that may take place both in the wastewater treatment stage and in the sludge stage. Various sludge disintegration technologies for sludge minimization are discussed, including mechanical methods (focusing on stirred ball-mill, high-pressure homogenizer, ultrasonic
