  • Mild cleaning: removal of 900 kg iron from a cooling water system - within 7 hrs - Case Study

    A professional cooling water treatment prevents the plant from corrosion damages. But in case corrosion should occur, severe damages can be the consequence. The cooling system needs to be cleaned. In contrast to a conventional cleaning with aggressive acids, Kurita suggests an innovative cleaning method: mild, material-protective and effective.   With the mild Kurita cleaning method amazing ...

  • Zentox system saves money by cleaning, reusing water

    Washing dead chickens uses water. No, make that lots and lots of water. Cleaning each chicken-and removing the contaminants and bacteria that the U.S. Department of Agriculture requires-uses about 10 gallons of water. So if you’re a typical chicken plant that processes, say, 200,000 chickens a day, you end up using 2 million gallons of water a day. Using that much water puts ...

  • Ozone treatment for cooling towers

    Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. ...

  • Are you `cooling challenged?`

    Although the Technology and Maintenance Council’s (TMC) taskforce looking into EGR cooler maintenance has not issued a “Recommended Practice,” from the literature and Internet searches, it seems heavy-duty diesels are by and large not susceptible to cooler problems. It’s the medium-duty trucks and Ford diesel pickups that are most troubled. The power units in question are ...

  • New Style Automatic Self-Cleaning Filters for Mill Cooling Water (Phase 1)

    ABSTRACT Replacement of hot-mill rolls is expensive and often requires production to cease during the process. Surface deterioration of rolls escalates as cooling water quality decreases. This manuscript will describe the installation and performance of a new cooling water filtration system in a northeast Ohio hot-roll mill that incorporates well proven suction scanning technology with ...

  • 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 ...

  • 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 ...

  • ASTM Standards Help Meet Need for Clean Water

    The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource. Clean and safe water is the underpinning of the quality of life for people around the world. Global economies depend on water, whether it’s to support the manufacturing of goods ...

  • 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 ...

  • Economical calculations for the use of Ozone in Cooling Towers

    Abstract Ozone has been successfully applied to industrial cooling water systems with the resultant improvement in operational efficiency due to increased heat transfer, reduced system corrosion, improved environmental impact and reduced on-going chemical expenditure. The aim of this paper is to provide practical advice on the options available for the application of ozone and the potential ...

  • Maintenance To-Do: Coil Cleaning

    A coil-cleaning program should be an integral part of maintaining some kinds of process cooling equipment. Most people think of coil cleaning as a building or facility prepares to turn on the air-conditioners for another season. Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list. Condenser and evaporator coils are an integral part of HVAC ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
