The Carmel Riviera Mutual Water Company believed it was losing big. Historical estimates indicated that more than 30% of this small, independent water company’s production was going down the drain through leaks, waste, evaporation and other types of loss. The company budgeted almost $60,000 per year in initiatives to reduce these leaks, including labor and materials for surveys and expensive repairs.

Wayne Daniel, head of operations at Carmel Riviera, decided it was time for better measurement and overall operational efficiency. When he contacted us, we recommended our affordable InnovaSonic® 205i, a digital ultrasonic flowmeter with clamp-on versatility that now helps the water company:

• Accurately measure water-loss percentage
• Improve production efficiency
• Improve water quality by reducing backflush
• More accurately bill users by identifying overusers.

Daniel says, “Implementing the InnovaSonic flow meter was not only an important step in making Carmel Riviera a more productive plant, but it’s also helping us drive water conservation.”

Warrendale, Pennsylvania, USA, 2012-Apr-04: The Italian company Multiservizi will install a Sludge Belt Dryer (SBD) from Siemens Industry Automation Division at its plant in the city of Jesi, Ancona. The belt dryer evaporation capacity is 2000 kg/hr. Once the dryer becomes operational in 2012, it will allow the Jesi plant to reduce the amount of biosolids produced annually by roughly 75 percent.

Multiservizi, a publicly owned Italian company, operates water and wastewater treatment plants for 45 communities in Italy. The plant in Jesi serves 60,000 residents. Its new SBD from Siemens will reduce sludge production from 16,500 to 4,125 tons per year. The plant, which also has a natural gas boiler, is designed to recover thermal energy from the cogeneration plant, thus reducing CO2 emissions.

With the SBD, evaporation takes place when biosolids come in contact with the heated air. Biosolids are uniformly distributed on the entire belt width to cause uniform evaporation. The dryer is supplied in a two-belt system configuration. The belt speed and the temperature of the process air can be adjusted for different residence times. Varying residence time in the drying zone provides the means to adjust the product moisture to meet final use or disposal requirements.

The Siemens' thermal drying system was selected because of the technology's high reliability and safety, low maintenance, and high automation level. Other advantages include high energy efficiency, minimal environmental impact, and agriculture-grade pathogen reduction.

The power delivered by a UPS is usually expressed both in volt-amps (VA) and watts. There’s often confusion about what the difference is between these figures and how to use them to select a UPS.

VA is power voltage multiplied by amps. For instance, a device that draws 5 amps of 120-volt power has a VA of 600. Watts is a measure of the actual power used by the device. VA and Watts may be the same. The formula for watts is often expressed as:

Watts = Volts x Amps

How the measurement of gas purity plays an important role across multiple gas processing industries and applications, mainly for the purpose of detecting gas impurities across a particular process. For example, in chemical reactions, one has to ensure the gases are free of carbon monoxide (CO) because of the risk of poisoning precious catalysts, oxygen (O2) might oxidize catalysts, and carbon dioxide (CO2) might form carbamates or carbonates which may clog process gas lines and lead to costly repairs.
