ATV-DVWK-A 198 - Standardisation (4/2003)

This Standard is concerned with the definition, collection, evaluation and examination of data as well as with the subsequent derivation of dimensioning values based on these for wastewater treatment plants and drainage systems. Forecast data for various time horizons can subsequently be derived from measured data. With this Standard the objective is pursued, globally for all DWA Standards and Adv... Learn More

DWA-A 199-1 - Operating Instructions (11/2011)

Operators of wastewater facilities shall establish service and operating instructions tailored to their respective circumstances in order to adhere to the requirements especially of § 57 of the German Water Resources Management Law (WHG) and in order to meet the minimum requirements of the self-inspection or self-monitoring ordinances of Germany's federal states. Since the regulatory content of t... Learn More

ATV-A 200 - Wastewater Rurally Areas (5/1997)

This Standard indicates possibilities for the economic realisation of an ordered disposal of wastewater in rurally structured regions. However, with all the currently discussed measures for cost reduction, the actual aims, protection of lakes and rivers and safety of local hygiene may not be placed in jeopardy. Wastewater treatment plants in rurally structured areas should not be planned, built an... Learn More

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 ... Learn More

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...

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... Learn More

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 ... Learn More

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... Learn More

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... Learn More
