Raw sludge measurement after primary clarifiers
Hangzhou Qige Water Treatment Plant measures the total solids from clarifier sludge and monitors mass flow with Valmet Total Solids Measurement (Valmet TS).
Developing an energy saving control system for sewage sludge drying equipment with real-time moisture content measurement
Nippon Steel Engineering, in Japan, wanted to increase the amount of dewatered sludge to the drying plant. With Valmet DS and Valmet HS their input moisture increased by 3.3% and the output moisture by 1%. At the same time, their fuel usage per moisture input was decreased by 5.5%.
Reliable solids measurements for centrifuge control
Vaasa Water’s Pått wastewater treatment plant wanted their new centrifuge to operate fully automatically, which requires several continuous measurements. With a Valmet TS and Valmet DS the plant can control the polymer dosing and measure the dry content. The whole project paid for itself in about 1.5 years through the considerable savings in the reprocessing costs of the dried sludge.
LNG-powered vessel sailing with Valmet DNA
The new LNG-powered vessel, Megastar was built by the Meyer Turku shipyard. Tallink meets the environmental challenges by using mainly liquefied natural gas (LNG) as fuel and Valmet DNA as automation system to enhance operational efficiency of the vessel.
Cake solids measurement elevates dewatering control
JEA’s Buckman Wastewater Treatment Plant, in Jacksonville, Florida, chose Valmet Dry Solids Measurement (Valmet DS), installed on the dewatering centrifuge, for accurate cake measurement. It’s been implemented for the plant wide mass balance control scheme.
Successful installation of Valmet TS at the Miyagi prefecture wastewater treatment plant
Mizumusubi Service Miyagi is involved in the Miyagi Prefecture's public-private partnership project for water and sewage operation systems.
More accurate and reliable Kappa numbers
Visy Tumut is an integrated pulp and paper mill with a kraft pulp mill and two board machines. To ensure the highest pulp quality, more accurate and reliable Kappa numbers are needed as feedback on how well their continuous digester meets the set pulp quality targets.
Valmet IQ at Paloma tissue mill in Slovenia
Replacing an aging quality control system on PM 6, this repeat QMS delivery followed an earlier start-up of a similar system on Paloma’s PM 5 in June 2016. The Valmet delivery included a traversing scanner, measurements for basis weight and moisture as well as machine direction controls.
Automation facilitates the development of LNG infrastructure
Transmission of energy will become more efficient with the use of measurement data.
Scrubbing to cleaner seas
Although the question of scrubbers has been at the forefront of the marine industry for a number of years, it seems that shipowners and shipyards are only now waking up to the fact that they are in a hurry to act before 2020 when the new SOx regulations come into effect. Everyone has been waiting – holding back – while the debate has been raging: scrubbers or no scrubbers at all?
