Bioetp Sludge Dryer System for oil Sludge Drying Treatment
Oily sludge mainly comes from the refining "three sludges" in the petroleum and petrochemical industry, that is the oil separator bottom sludge, dissolved air flotation scum and excess activated sludge generated in the process of wastewater treatment in refineries; coal-to-oil, coal-to-oil Biochemical sludge, gasification wastewater pretreatment sludge, etc. produced by coal chemical industries ...

Respirometry study about the olive oil effects in the activated sludge process case study
The problem of Oils in the Activated Sludge Process In many activated sludge plants excessive oils discharges can give rise to Nocardia foaming which causes major operational problems. While the bulk of the oils are removed in Dissolved Air Flotation (DAF) units or grease interceptors the remainder must be treated in the wastewater treatment system. But however, in case of high concentration, ...

A critical review of experimental and predicted methane generation from anaerobic codigestion
Anaerobic digestion is increasingly being considered as a treatment option for an extensive range of waste biomass, due to the potential for energy recovery, in the form of methane production, and lower sludge volumes relative to aerobic treatment processes. Furthermore, when two substrates are codigested (i.e. digested together), added benefits are foreseeable, such as increased methane ...

What is sludge disc dryer
The disc type sludge dryer is composed of a horizontal shell and a rotor with heating. A plurality of heating discs are installed on the rotor, and an angle-adjustable pusher is installed on the rotor. The material is heated, and the material can be pushed along the direction of the discharge end. The steam distribution device inside the rotating shaft can evenly distribute the steam to each ...

Spilled heavy grade heating oil case study
Heavy fuel oil escaped from a storage tank and entered the drainage system of a large creamery. This material passed to the aerated balance tank which precedes an activated sludge system treating the factory waste waters. Alerted to the spillage the operators were able to shut off the flow to the activated sludge system but not before a significant quantity of oil had passed through. Bio-Systems ...

Savanna wastewater treatment plant case study
Performance History and Discussion Jackson, MS selected In-Pipe Technology Company, Inc. for the Savanna WWTP with goals to reduce the quantity of waste sludge for disposal and control FOG in the collection system and at the plant. Jackson, the capital and largest city in Mississippi, was looking for ways to reduce sludge expenses from polymer to hauling and disposal fees. In-Pipe was first ...

Wastewater Treatment Process
The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

Summary and Schemes of Sludge Drying Technology
#sewagesludgedewatering #activatedsludgesewagetreatment Due to the high output, high moisture content and huge volume of sludge in the increasingly large-scale sewage treatment plant, it is not only inconvenient in the process of storage, transportation, loading and unloading, but also has high potential environmental safety risks and hidden dangers. The cost of sludge disposal in some ...
