ACEA Ato 2 and SWAN Analitica srl Italy agree to framework agreement on turbidimeters


As an integrated multi-utility leader, Acea offers services in water, energy and environmental business. It is a leading Italian operator in the potable water sector with approximately 9 million inhabitants served in Lazio, Tuscany, Umbria and Campania.

Acea manages a very extensive potable water network of around 10'000 km and 210 sources of water supply. Special emphasis is put onto instrumentation requiring lowest possible maintenance (cleaning, calibration, spare parts). The three year framework agreement is based on a long-term customer relationship dating back to 2004 and applies to Acea Ato 2, which manages the potable network in Rome and neighboring municipalities.

Since its successful trial period in 2013, the installed turbidity monitor AMI Turbiwell has worked without maintenance to this day, thereby living up to the customer's expectations. This has ultimately paved the way for the 3-year contractual agreement.

SWAN’s AMI Turbiwell is a non-contact turbidimeter which requires a minimal maintenance, with no moving parts. Furthermore, the AMI Turbiwell only requires a low sample flow to measure – which is especially appealing to smaller sized water treatment works. Due to its measurement principle, the AMI Turbiwell can be applied to all types of water – from pure water through to effluent. It can also easily cope with heavily gassed samples, making it the ideal solution to all water monitoring requirements.

SWAN proudly announces its newest product development: Handheld Chematest 30

Chematest 30.jpg

With the introduction of Chematest 30 SWAN broadens its range of applications for handheld water quality testing devices. In addition to potable water treatments and public pools, these successor models to the well-proven Chematest 20/25 photometers are now qualified for use in pharmaceutical production and food processing.

Primary improvements affect the area of application and user-friendliness. In order to comply with pharmaceutical and food industry requirements, every photometer is calibrated individually and its light source traceable to NIST standards. Traceable verification kits and glass cuvettes additionally assure reliable and safe utilization. 

Its menu-driven user guidance has been revised to simplify measurement handling. The IP 67 waterproof design, its long-living, rechargeable Li-Ion battery and the large internal data storage make Chematest 30 the perfect handheld for mobile water analysis in any circumstances. 

Disinfectant measurements:  

  • Free, Combined and Total Chlorine
  • Ozone
  • Bromine
  • Iodine
  • Chlorine Dioxide

Additional photometric methods:

  • pH (Phenol Red)
  • Cyanuric Acid

More newly introduced Chematest 30 highlights:

  • User Management
  • Registration of Sampling Points
  • Bluetooth 4.0 Low Energy
  • Improved Case with Removable Reagent Rack


Release date Chematest 30: Availabe now!

A long tradition of SWAN is to support a water project by Helvetas to help improve the drinking water and educate the locals on proper water handling and basic hygienic rules to prevent diseases. This year SWAN is supporting the project Sodis in Bolivia. By working with Helvetas for many years, we can guarantee that our donations are being used properly. SWAN thanks you for your trust and your confidence in SWAN during this successful year. SWAN wishes you and your family happy holidays and all the best for the coming year.  

Singapore International Water Week


Meet us at the Singapore International Water Week, the global platform to share and co-create innovative water solutions.

Don't miss your unique chance to gather comprehensive information about all our available services as well as our cutting-edge developments and technologies in on-line process water analysis.

As an example, we will present our turbidity meter AMI Turbiwell and its verification procedure. Due to the technology used and the design of this instrument, a calibration is not necessary. However, we developed the enhanced secondary standard procedure to enable operators to determine periodically if the instrument is still in calibration.

Furthermore, our Product Manager, Dr. Alexander Rodenberg, will be giving a presentation about the SAC254 measurement on Tuesday, 10th of July in Treatment B, Level 3.0, Cassia 3201AB - Starting at 02:00 - 03:30 PM.
