DWA-M 507-1E - Levees Along Watercourses (12/2011)
The leaflet’s span of application was extended from ‘Levees’ to ‘Levees built along watercourses: Introduced to this end was a classification system that categorises the levees by height and inherent risk potential, therewith covering a bandwidth of vital aspects of the involved design and engineering work.Described are the specific hydraulic design parameters, the documentary evidence to ...

ATV-DVWK-M 503 - Tailings Impoundments (12/2001)
The focus of this advisory leaflet is thus on the plant safety from a constructional and hydraulic engineering point of view. It nevertheless seeks to devote adequate space to the environmental aspects of such facilities which are receiving increasing recognition.The advisory leaflet the contents of which are primarily keyed to existing plants, whether still in service of decommissioned, will prov...

DWA-M 387 - Thermal Treatment (5/2012)
The objective of the Advisory Guideline DWA-M 387 is to give fundamental information for the technical realisation and operation of plants for the co-incineration of sewage sludges in coal power plants. Based on fuel characteristics of sewage sludge, the effects of co-incineration on various fi ring systems for brown and black coal, on fl ue gas purifi cation and on incineration residues are dealt...

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-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 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...

ATV-DVWK-M 362-2E- Dredged Material (10/2004)
The case studies introduced describe possibilities of avoidance, restorage, usage, storage in water bodies and on land as well as reconditioning, recycling and finally disposal of dredged material from inland water bodies which are implemented in practice. Special focus was put on dredged material from water bodies of the the German Federal states and municipalities as exemplified with the ... Mehr erfahren
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 277E - greywater (10/2017)
The urban water management must address new challenges. Examples include the impact of demographic trends and climate changes or the implementation of resource protection measures. New Alternative Sanitation Systems (NASS) represent one potential approach, where technologies are used to close as far as possible the water and material cycles for the purpose of recycling the valuable componen...

DWA-A 272 - New Alternative Sanitation (6/2014)
In recent years, numerous research and demonstration projects have been carried out at national and international level in the field of new urban water infrastructure systems, leading to new insights and technical concepts. Background of this work are in particular the emerging changes in key framework conditions for water infrastructure, including additional requirements from the point of ... Mehr erfahren
