Description

You want to open up new markets with small wastewater treatment plants, or launch a new model on the market? If so, you have found the right partner in PIA.

You can count on us to answer all the necessary questions about market requirements and the certification of your products. Indeed, you can launch conventional or innovative projects most successfully with a competent partner. We will support you with our unique know-how whenever your product has to comply with the water legislation requirements in different countries or regions. Since we actively participate in numerous national and international boards as well as on technical and standardisation committees, we are always up to date: something your company can benefit from. Take advantage of our competence, motivation and determination to achieve your goals.

"Sustainable Certification" is more than just a slogan. It describes the two decisive core elements for you: first, certifications and test reports should be used as long as possible and, second, they represent not only the legal basis for your sales, but are also welcome evidence of how well your product performs.

The tests, followed by declaration of performance, are the key to success. We would be pleased to consult you on these matters. Let us work together efficiently as partners. Take the time and give us a call.

CE tests according to EN 12566

The basis for a successful market entry in Europe is the CE marking of your product. For this purpose, the series of standards – EN 12566 – is used. Five of the seven standards have been harmonised and, with our support, you can receive a declaration of performance according to one of these standards and place it on your product. With it, small wastewater treatment plants can be traded legally throughout Europe.

EN 12566 complete

 

The standard EN 12566 is divided into several parts, each of which defines the basis for the respective tests:

NSF International tests

Tests according to NSF/ANSI standards are recommended if you would like to enter the American and Asian markets with relative ease.

Currently, the only place in Europe where tests according to NSF/ANSI Standards 40, 245 and 350 can be carried out is on PIA's test field in Aachen. For over ten years, PIA has maintained successful cooperation with NSF.

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.

Material tests

The materials listed in the standard for tanks of small wastewater treatment plants are varied as the possible treatment processes themselves. The materials allowed range from classic reinforced concrete, via fibre-reinforced plastics through to stainless steel.

All materials, or containers and tanks manufactured from them, have to prove their suitability in terms of their intended use. In addition to tests for structural behaviour and water tightness, there are also the proof of reaction to fire, durability and a leaching test to verify if any dangerous substances are present.

PIA GmbH has partners and co-operative bodies throughout Europe and can provide the appropriate material tests and the required expertise, wherever needed.

Special tests

Thanks to close cooperation and individualised support, we are also able to offer you special tests. This way, we can confirm even more performance options of your system, even if they are not necessary for the CE marking.

The following special tests are possible:

 

Such a special test, however, does not replace the test procedures according to EN 12566 and cannot alone count as a valid test. Only when a small wastewater treatment plant has successfully completed all relevant tests according to EN 12566 can the system be CE-marked.

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
