  • Low recirculation rate evaporators

    Abstract Fin coil evaporators with enhanced internal tube surfaces allow for optimum performance with a minimal overfeed rate. Reducing the overfeed rate requiresless pumping power and smaller line sizes to the evaporator. Additionally, less compressor power is required for the same refrigeration capacity because the wet suction line pressure drop is reduced. Lower compressor power results ...

Environmental regulation required the plant ...

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...

  • Selection and economical evaluation of solar desalination technologies via DesalSolar software

    Worldwide projection indicated that in 2020 the situation of water resources in Iran reach to scarcity. Besides, global warming and energy crisis have forced countries to use renewable energy resources. Solar desalination technologies particularly in remote area of Iran could be a method to emancipate from this crisis. In this paper, all kind of desalination technologies were reviewed. Then, ...

  • Advances in desalination technology

    Seawater desalination has been the cornerstone of the Middle East's water supply strategy since the mid-1950s, and most of the installed desalination capacity is still provided by multistage flash evaporators. But, desalination is changing. In fact, the term "desalination" is no longer limited to seawater applications; desalination technologies are now routinely employed to desalinate brackish ...

  • Refrigerant leak creates environmental problems for businesses

    A great concern for companies is a refrigerant leak in their refrigeration and air-conditioning (RAC) system or heating, ventilation and air conditioning (HVAC) system. That’s because gases that escape during a refrigerant leak pollute and damage the environment. To better monitor and maintain the operation of these business assets, many companies utilize a refrigerant management program.There ...

    The United Nations System of National Accounting (SNA) framework provides an internationally agreed methodology for national economic accounts. SNA accounts are the main source of information for the internationally comparable economic aggregates and indicators which are used to assess the economic performance of countries. Examples are gross domestic product (GDP), value added, income, ...

  • Stormwater Management Improvements Spurred by Low Impact Development Techniques

    Abstract A concept first advanced in 19901, evidence of Low Impact Development (LID) can now be seen across North America. Like many infrastructure transformations, this growth in LID design has benefitted from regulatory changes; compliance versus cost remains an important motivator in any ...

  • Two Case Histories of Industrial Water Reuse Via Membrane Technology

    Abstract This paper describes two successful applications of ultrafiltration (UF) and reverse osmosis (RO) membrane technology used to reclaim water, reduce waste water discharge costs. The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major ...


  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • The search for water contamination can create hazards of its own

    It''s a paradox. Most of the very technologies being used today to test water for contaminants actually return more pollution to the environment than the tested water itself. Nevertheless, as we all know, water testing is crucial to our health. Modern industry has unleashed tens of thousands of chemicals into the environment. Many of these chemicals are essential, but it''s the control of them ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...
