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-A 118E - Hydraulic Dimensioning (3/2012)

This DWA Standard concerns the dimensioning and verification of drain and sewer systems, which are mainly operated as gravity systems and which serve for the discharge of domestic and industrial wastewater, surface water and combined wastewater. It contains guidance for determining the quantities of wastewater to be discharged, taking into account both the replanning and the recalculation of exist... Learn More

Appraisal Manual for Project Designers (12/2011)

Ensuring value for money in public utilitymanagement, by following the principle of economic efficiency and cost consciousness, has always been a pivotal point for the water sector. This manual is an adopted version based on German standards, as documented in the regularly updated “Guidelines for the Application of Dynamic Cost Comparison Calculations (DCCC-Guidelines)“. Within the framework... Learn More

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... Learn More

Practical Guideline Operational Problems

The publication entitled ‘Operational Problems in Wastewater Treatment Plants – A Handbook for the Operation of Wastewater Treatment Plants’ offers a practice guideline for troubleshooting operational deterioration in wastewater treatment plants. It is a useful tool for wastewater treatment plants’ operators helping them to optimize daily operations, to troubleshoot operational problems an... 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-A 125E - Pipe Jacking (12/2008)

This Standard deals with the underground installation of pre-fabricated pipes with different geometry of the cross-section. During the installation, a cavity is created in the ground by displacing, ramming, drilling, pressing or other installation. The pipes are pulled, pushed or pressed into this cavity or existing sewers or pipelines are passed and/or replaced. For shield drives (e. g. segment l... Learn More

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... Learn More
