Enelco: A Legacy of Water Treatment Excellence Lives On

Enelco, formerly known as Environmental Elements Co., was a prominent name in the water treatment industry. Known for its innovative and reliable solutions, the company played a significant role in shaping the landscape of environmental engineering. In 2005, Enelco's water treatment product line was acquired by Infilco Degremont, Inc., a global leader in water and wastewater treatment technologies.

A History of Innovation and Success:

Enelco's legacy is marked by a strong commitment to research, development, and practical application of water treatment solutions. Their product line encompassed a wide range of technologies, including:

  • Coagulation and flocculation: Enelco's expertise in chemical treatment processes, including alum, ferric chloride, and polymer applications, played a crucial role in removing impurities from water sources.
  • Filtration: Their filtration systems, including gravity sand filters, pressure filters, and membrane filtration technologies, provided efficient and reliable methods for removing suspended solids and other contaminants.
  • Disinfection: Enelco offered a diverse range of disinfection solutions, from traditional chlorine disinfection to ultraviolet (UV) treatment systems, ensuring safe and potable water supply.
  • Softening and Deionization: Their water softening and deionization systems addressed hardness issues and minimized the presence of dissolved salts, critical for industrial and commercial applications.

The Acquisition and Continued Legacy:

The acquisition of Enelco's water treatment product line by Infilco Degremont marked a significant step in the consolidation of the water treatment industry. It brought together two established players with complementary expertise and resources. This strategic move allowed Infilco Degremont to broaden its product portfolio and expand its reach in the global market.

While Enelco as a separate entity no longer exists, its legacy continues to influence the water treatment landscape. Infilco Degremont actively maintains and supports the Enelco product line, ensuring that the high-quality and reliable solutions developed by Enelco remain available to customers worldwide.

The Importance of Water Treatment:

The importance of effective water treatment cannot be overstated. With increasing global populations and the growing pressure on water resources, reliable and sustainable water treatment solutions are crucial. Companies like Enelco and Infilco Degremont continue to play a vital role in ensuring access to safe and clean water, contributing to public health and environmental sustainability.

Enelco Exercise:

Scenario: You are a water treatment engineer working for a small municipality. The town's water supply has been experiencing high levels of turbidity (cloudiness). You have been tasked with recommending a suitable water treatment solution.

Task:

  1. Based on Enelco's expertise, identify two water treatment technologies that could effectively address high turbidity.
  2. Briefly explain how each technology works to remove turbidity from water.
  3. Briefly explain the advantages and disadvantages of each technology.

Exercice Correction

Solution:

  1. Two suitable technologies:

    • Coagulation and flocculation: This process uses chemicals (like alum or ferric chloride) to neutralize the charges on suspended particles in water, causing them to clump together (flocculation). These larger clumps are then easier to remove through sedimentation or filtration.

    • Filtration: Enelco offered various filtration systems, such as gravity sand filters or pressure filters, to remove suspended solids from the water. These systems typically use a bed of sand or other filter media to trap the particles as water flows through.

  2. Explanation of how each technology works:

    • Coagulation and flocculation: This process involves three main steps:

      • Coagulation: Chemicals are added to the water to neutralize the charges of particles.
      • Flocculation: The particles clump together to form larger, heavier flocs.
      • Sedimentation: The flocs settle to the bottom of the tank, leaving clear water on top.
    • Filtration: Water is passed through a filter bed made of sand, gravel, or other materials. The filter media traps suspended particles, removing them from the water.

  3. Advantages and disadvantages:

    • Coagulation and flocculation:

      • Advantages: Effective for removing a wide range of suspended particles. Relatively inexpensive.
      • Disadvantages: Requires careful chemical dosage to avoid overdosing. Can introduce additional chemicals into the water.
    • Filtration:

      • Advantages: Reliable and effective for removing suspended particles. Can remove other contaminants, such as bacteria and viruses.
      • Disadvantages: Requires regular maintenance (backwashing) to prevent clogging. Can be expensive for large-scale applications.
