23-16: A Comparison of a New Maleic Terpolymer with Current Maleic Terpolymers for use in Cooling Towers Water Treatment

23-16: A Comparison of a New Maleic Terpolymer with Current Maleic Terpolymers for use in Cooling Towers Water TreatmentAt present, cooling water formulations include using several maleic terpolymers to control calcium carbonate and perform corrosion control when used with zinc. This laboratory study compares a new maleic terpolymer (MTP A) with current maleic terpolymers in tests of calcium carbonate inhibition, calcium sulfate inhibition, calcium phosphate inhibition, silt dispersion, and iron oxide dispersion to assess the efficiency of scale control. The study

Procedures have been developed for the successful evaluation of four water treatment biocides versus the acid-producing bacteria Thiobacillus novellas and the iron oxidizing bacteria Leptotrhix discophoro

compared to competing processes

In cases where calcium is the blow-down determining constituent

In particular

Legislation has been tailored to ban the discharge of toxic materials into streams and water ways

operating motors on adjustable speed drives

The paper identifies the activities and justification involved leading up to this replacement as well as the procedures performed to actually demolish and rebuild these (2) towers during a 5-week outage

Sensor technologies will also be discussed including inclinometers

and an appropriate closing statement

Finally a super low noise fan with special shape could only be accepted

During the past two years

The reduction of drift and corresponding mineral mass emissions was about 80%
