ATV-DVWK-A 281 - Trickling Filters (9/2001)

The biological stage of wastewater treatment plants, employing trickling filters and rotating biological contactors without sludge return feed, is dealt with in this Standard. The standard applies only for rotating biological contactors without artificial aeration for the supply of the biofilm with the required oxygen. The development of the trickling filter process and the rotating biological con... Mehr erfahren

DWA-M 366E - Dewatering (2/2013)

Dewatering of sewage sludge is one of the most important fundamental process steps in the entire sludge treatment chain. For decades, various mechanical dewatering aggregates have been operated at wastewater plants. This Guideline summarises commonly used systems as well as their dewatering efficiency and cost effectiveness. Furthermore, it presents information on operational requirements and cond...

DWA-M 381E - Sludge Thickening (10/2007)

Thickening of sewage sludge is one of the most important basic treatment steps of the entire sludge treatment process. For decades thickening of sewage sludge has been accomplished by using either gravity settling in thickeners or in a flotation unit or by mechanical thickening. Flotation and mechanical thickening processes are almost solely used for the thickening of waste activated sludge. In 19... Mehr erfahren

DWA-M 386E - Thermal Treatment (12/2011)

Thermal treatment of sewage sludge is in regard to quantity the most important disposal route in Germany. It is an important option for a safe, economically efficient and environmentally sound sludge disposal. Since the late 1980ies, the percentage of sludges which are treated thermally has risen from about 12 % to more than 50 %. Almost half of these sludge quantities are treated in mono-i...

DWA-Topics - Wastewater Treatment plants (10/2016)

The design of wastewater and sludge treatment plants under deviating wastewater and climatic conditions in other countries requires an amendment of existing design rules compliant to the DWA Set of Rules, which have been primarily developed for Central European conditions. This concerns, for example, the consideration of high or low wastewater temperatures, increased salt content or special... Mehr erfahren
