  • Cooling tower water treatment – 3 ways to handle cooling tower operations

    Cooling tower water treatment is one of the most important factors to enhance the performance and reduce the maintenance cost of cooling systems. Cooling towers are large evaporation systems that evaporate water to remove heat to cool process water in applications including, air-conditioning systems, water cooling for equipment and general manufacturing requirements. The heated water is typically ...

  • Bypass filtration in open circulating cooling water systems

    An open circulating cooling system is a method to remove process heat and is applied frequently for industrial purposes. In these systems heat is removed by evaporation of water to the surpassing air in the cooling tower. However there are some environmental disadvantages such as addition of chemicals to prevent the cooling water system from microbial growth and corrosion. The application of ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • RYDLYME improves efficiency on cooling tower case study

    A 35-ton cooling tower at a major college had compressors operating at more than 260psi just to maintain a 70°F water temperature due to heavy water scale. RYDLYME was put into the system to dissolve the scaling. RYDLYME approach 55 gallons circulated for 4 hours via inline pumps and then flushed with water. Cleaning was done while system was in ...

  • Cooling water temperature decreases at pharmaceutical facility case study

    A large pharmaceutical manufacturer in Puerto Rico was experiencing severe scaling problems in its cooling tower/chiller systems resulting in decreased performance and efficiency. RYDLYME approach 1,320 gallons of RYDLYME circulated through the system for 24 hours followed by thorough water flush. RYDLYME results After the 24-hour ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • Reclaimed Municipal or Industrial Wastewater for Power Plant Cooling & Boiler Feed Make-Up Water

    For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. State and Federal agencies have put in place guidelines and regulations restricting its use, especially for industrial use. ...

  • Delta-T increased at biopharmaceutical manufacturing facility case study

    The cooling towers at a biopharmaceutical manufacturing company in the Midwest had become packed with scale. The severe scaling resulted in the inability of the towers to maintain any cooling capacity during extremely hot summer temperatures. RYDLYME approach 660 gallons circulated for 6 hours. RYDLYME results Cleaning resulted in Delta-T ...

  • Gravity self-backwashing filters

    The filtration of make-up and side-stream water in closed cooling circuits, operated through cooling towers, is a fundamental step to ensure safe and continuous operations in a power plant. Water - required in large amounts for this application - should not be wasted, and the potential damages deriving from a poor treatment must be avoided at all cost. BONO ARTES has developed a technical ...

  • New definition of fluid exergy in a gravitational field

    This paper discusses the concept of working fluid exergy in an atmosphere stratified by a gravitational field, particularly the hot humid air in the atmosphere. A definition of exergy, different from that recently proposed by Petela (2008), is presented. Thermodynamic diagrams illustrate its elements and its technically feasible part in a transparent way. Reference papers are given for ...
