  • 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 ...

  • Thermodynamic modelling of a water-to-water heat pump using propane as refrigerant

    The aim of this paper is to develop a thermodynamic model for a water-to-water heat pump using propane as refrigerant. This model is based on the thermodynamic principals and heat transfer fundamental laws. The performances of the heat pump have been looked at as function of the water temperatures at the entry of the evaporator and the condenser. The results show that the cooling and heating COP ...

  • Signs You Need a New Water Pump

    Motor vehicles are built upon small parts doing big jobs. Consider your engine. It is likely the most important machine within your car, truck, or SUV, but it is not made up of one or two components, but thousands. Some engines have over 14,000 different parts to keep them operational. If just one of these parts, such as the water pump, fails, then the entire engine could grind to a halt. ...

  • Cooling tower case study

    Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

  • Water treatment helping cars stay cool - automotive industry: Orlando, Florida

    A manufacturer of air-conditioning line connectors for automobiles was required by the city to meet new sewer discharge standards. They had been using a system of gravity separation which did not address suspended solids or soluble metals. Their wastewater is generated from 3 sources; mop water, parts deburring and polishing, and floor scrubber water. They generate approximately 6,000 gpd 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 ...

  • Improved Control for your Cooling Tower and Boiler

    The power of microprocessor based programming along with the ease of interfacing with standard Internet based controllers has enabled improved cooling tower and boiler control with just the click of a mouse. Many of these improvements can significantly enhance your chemical treatment program, and provide greater flexibility in your chemical treatment program. These new algorithms offer ...

  • CO2 Reduction by Cooling Tower Retrofit Measures

    Abstract : In the course of a cooling tower retrofit a cold-end-optimisation should be done. Due to installing best available technology of cooling fills a decrease of cooling water temperature and additional power output can be generated. The following consideration shows options of improvement and takes a look at the economic importance. Introduction: Increase in efficiency of ...

  • Cooling tower for Chemical processing plant - case study

    This chemical processing plant needed clean, debris-free water for cooling purposes. We created custom traveling water screens for their cooling tower that are compact and efficient. Smaller mesh sizes can catch fine debris for a this type of installation. No matter what architectural or engineering constraints, we’ll create a water screen solution that fits. This project included: ...

  • 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 ...

  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...
