Historically, ample sources of fresh water allowed Papermakers considerable flexibility in dealing with problems on the paper machine. In very open water systems, soluble chemicals could be sent out of the system and dealt with through discharge. Abundant, inexpensive, high quality fresh water has become a dream of the past in many regions. Even more critical are environmental regulations that severely limit discharge of mill wastewater. Changes made in response to these pressures can impact the microorganisms that colonize the paper machine. Key Words: bacteria, BOD, closure, COD, corrosion, deposits, effluent, filamentous bacteria, slime, water consumption, water management, whitewater
