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.

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.
