20-10: Sustainable Water Treatment Technology for Cooling Towers Using Next Fan PerformanceCooling tower water faces challenges of bacteria growth, biofouling, and mineral scaling on the heat transfer surface, which aggravates additional issues such as corrosion and transfer efficiency loss. Although conventional chemical treatments address these issues, they offer only a temporarily solution, which increases the effluent salt concentration over time. Furthermore, periodic blowdown becomes necessary with increase in total dissolved solids
because the leaking water contains various organic and inorganic substances used for its treatment
Several useful mechanical maintenance recommendations and chemical application modifications for often problematic operations will be provided based on long term zero discharge experiences
users and recognized engineering groups"
and improve safety and health outcomes
additional make-up water is needed to replaceevaporation and blowdown losses
This document serves as a guideline for techniques and instrumentation that can be used to measure airflow and other fan performance parameters on induced draft in situ heat rejection equipment having axial fans
The Simplex pitot tube has long been used for water flow rate determinations
technical impact of noise requirements on all components and verification
All samples were analyzed and tested both full scale and as coupons
cooling water formulations include using several maleic terpolymers to control calcium carbonate and perform corrosion control when used with zinc
an adiabatic fluid cooler or refrigerant condenser) is the best solution to balance costs
Pros and cons of this approach will be discussed
