AS 1546.3:2017
On-site domestic wastewater treatment
Units Part 3: Secondary treatment systems

The AS 1546.3:2017 sets out requirements for the design, commissioning, performance and conformity testing of secondary treatment systems (STS) and advanced secondary treatment systems designed to treat domestic wastewater. The design hydraulic treatment capacities that may be tested in accordance with this Standard range from a minimum of 1200 L/d to a maximum of 5000 L/d. Guidance on installation, operation and maintenance is also provided.

Lecture: New storm water treatment

Lecture on the current topic:

Performance and testing of decentralized stormwater treatment systems“

The progressive sealing of land and anthropogenic contamination require solutions in the field of stormwater treatment. Nearby treatment and infiltration help to relieve hydraulically stressed drainage systems, contribute to the restoration of the natural water balance and take targeted action at the point of pollution. Decentralized stormwater treatment plants can offer an alternative.

In Germany, but also in other countries, requirements are already being placed on these systems and they are being tested under laboratory conditions. The presentation shows the current problems, gives an overview of the different treatment systems and their possible applications, and presents the test requirements and the tests itself.

 Speaker: Daniela Schmitz, Time: 09.02.2022 at 10:00 a.m., Language: English

Duration: Max. approx. 30 minutes each + 10 minutes questions / discussion / feedback

Successful transition to new ISO/IEC 17025 version

On November 19th, 2020 PIA's accreditation was successfully converted to “DIN EN ISO/IEC 17025:2018-03 General requirements for the competence of testing and calibration laboratories (ISO/IEC 17025:2017)

The scope of the accreditation, as well as a list of testing methods can be found in the "Directory of accredited bodies" at DAkkS.de.
DAkkS is a full member of the International Laboratory Accreditation Cooperation (ILAC) to ensure mutual recognition under the ILAC MRA.

Guidelines for technical performance test of small sewage treatment systems in China

PIA GmbH and CWEG (China Water Environment Group) are preparing a project for the Chinese Environmental Protection Industry Association to develop "Guidelines for technical performance test of small sewage treatment systems".
