Paper mill water quality can boost OEE
and profits
Paper mills report an average of 4% increase in OEE (Overall Equipment Effectiveness) by simply focusing on water quality
A small investment in a simple liquid monitoring system has proved to be a great success in 40 paper mills across Europe and the Americas "The key to our success during the past eight years has been the ability to analyse electrochemistry in large volumes of liquids, and process data effectively in real-time in order to detect abnormalities and changes in water quality" said Sakari Laitinen, CTO, Liqum Paper: "The system predicts problems, eliminates risks and costs associated with unforeseen process interruptions, and ensures sufficient time to take corrective action"

On average, paper mills consume about 50 cubic meters of freshwater per ton of paper or pulp produced.
Since the pulp and paper industry uses so much water, and produces so much wastewater and recycling water, controlling water quality throughout the production process is crucial to avoid and eliminate problems, boost bottom-line profits, and reduce the burden on the environment.
Constant water quality monitoring is critical in every papermill.
Raw, treated and waste water quality varies from place to place, depending on the condition of the source water from which it is drawn, and the treatment it receives.
The amount of chemical agent added is critical for optimum performance.
Both underdosing and overdosing of the chemical agent affect the water quality and leads to poor performance.
Because the water characteristics and chemical agent demand are constantly changing, it is essential to continuously monitor electrochemistry in liquids to optimise the chemical dosage.
Real-time analysis of the water quality and the performance of a chemical agent allows adjustment of a chemical dosage at all times, and development of a feed optimisation system.
Real-time electrochemical liquid analysis offers a series of advantages that lead to higher OEE including; increased accuracy and detection limits; low cost of implementation; minimises waste and by-product formation; savings of water, energy and chemicals.
A small investment in the Liqum liquid monitoring system can easily pay for itself within a year, push profits and company valuations to higher levels.
