Baffle Systems

As one of the leaders in the wastewater industry, IEC is at the forefront of wastewater baffle design. Our baffles prevent short circuiting and effectively direct the flow through your wastewater treatment pond, lagoon or tank, improving retention, settling time and overall wastewater treatment.  Our wastewater baffles enable an entire basin to be used effectively.

Our baffles are custom-designed to fit your specific application, using wastewater compatible materials for a wide range of municipal and industrial wastes. We offer installation supervision to insure your floating baffle is installed correctly.  IEC’s baffles offer the following benefits:

  • Improved retention time
  • Improved settling time
  • Direct water flow
  • Preventing short-circuiting
  • Better mixing
  • Increased food to mass contact, improving wastewater treatment

They are floating cover compatible for our aerobic and anaerobic cover systems.

We can provide the following types of baffles:

  • Floating Baffles
  • Clearwell baffles
  • Partial and full depth Pond and Tank baffles

At IEC, our decades of experience and attention to detail are what sets us apart from other baffle system manufacturers. Contact us today to learn more!

Here is some more information on our Floating Baffles.

Floating Baffles Improve Wastewater Performance by Eliminating Short-Circuiting

IEC’S Baffles are a critical component for pond-based systems to increase hydraulic retention time (HTR). Eliminating short-circuiting is achieved by managing the flow path and circulation in wastewater treating ponds. Floating baffles can greatly reduce or eliminate dead zones and improve treatment efficiency. Baffles are also referred to as hydraulic baffles (curtains), bio separators, floating baffles, lagoon baffles and water curtains.  Regardless of the name, they are commonly used in a large range of wastewater facilities and reservoirs in addition to industrial and municipal water treatment facilities. The baffles improve water quality at the plant by increasing the effective treatment area and contact time the microbes have on the wastewater.

Floating baffles are designed to create serpentine hydraulic flow patterns. Most baffles are constructed of flexible membrane that float on the water surface. They can also be attached to walls and floors when used as a tank baffle. If properly designed and installed, pond and tank baffles can significantly contribute to the reduction of Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS). Floating curtain baffles are constructed with heavy duty tension members at the top and typically a ballast chain attached to the bottom.

Floating baffle curtains greatly reduce short circuiting across the lagoon and ponds. Once the baffles are installed, they do not require any further maintenance. IEC also specialize in designing and installing floating baffles and floating covers so they can be installed together.

IEC’s baffles are designed to improve water quality by eliminating short-circuting and increasing detention time in ponds and tanks.  Baffles are commonly used in water treatment facilities, industrial processes, and stormwater management systems. As experts in the field, we will recommend the correct design from the best geomembrane and materials for your specific application.

Types of Baffles

We offer a wide range of baffles to suit your specific needs. Our selection includes floating baffles, perforated baffle walls, and porous baffle designs. These baffles come in various materials, such as XR-5, HDPE and variety of other materials.

  • Floating Baffles
  • Clearwell baffles
  • Partial and full depth Pond and Tank baffles

Each type of baffle serves a specific purpose, and our knowledgeable team can help you determine which one is best suited for your application.

Benefits

Baffles direct the flow of water, typically in a serpentine pattern.  They  enhance the efficiency of water treatment facilities by preventing short-circuiting and improving effluent water quality for BOD, ammonia and TSS. They are a cost-effective solution to managing water flow and ensuring optimal water treatment in both industrial and municipal settings.  Our baffles are being successfully used by a wide range of clients and industries including municipal wastewater treatment plants, stormwater retention ponds, and industrial process water , mining, refineries, anaerobic and aerobic systems.

Installation

IEC is committed to making the installation process as smooth as possible for our clients. From site assessment and baffle selection to post-installation inspection and adjustments, we ensure that your water baffle system meets all specifications and requirements. Whether you need a floating baffle curtain for your pond or tank, our expert technicians will ensure proper installation and optimal performance.

Frequently Asked Questions

Q: What is the purpose of installing baffles for wastewater treatment?
A: Installing baffles in a wastewater treatment pond, reservoir or tank ,it helps improve water quality by controlling circulation, reducing debris flow, and enhancing the efficiency of water treatment processes. Baffles reduce the total suspended solids (TSS) and biological oxygen demand (BOD) in the water, ultimately leading to cleaner water.

Q: How do tension members and ballast chains contribute to its strength and effectiveness?
A:
Tension members and ballast chains are essential components. Tension members provide strength and stability, ensuring that the baffles maintain their shape and position, while ballast chains help anchor the baffles to the bottom of the treatment area, keeping them in place even in areas with high water flow or navigation.

Q: Are IEC’s baffles suitable for use in cold climates like Minnesota?
A:
Yes, our baffles are designed to withstand a range of temperatures and weather conditions, making them suitable for use in colder climates like Minnesota. Our high-quality materials and construction ensure durability and effectiveness in various environments.

Q: How do I determine the right size and type for my treatment area?
A:
The size and type needed for your treatment area will depend on factors such as the area and configuration of your basin, the amount of water flow, and the specific water quality issues you're facing. Our knowledgeable team at IEC can help you assess your needs and recommend the most suitable water baffle options for your situation.

Q: How do baffles and turbidity curtains work?
A:
Baffles help settle solids and sediment from the water and control turbidity c within the treatment area.

Q: Can your water baffles be used in reservoirs and other large-scale applications?
A:
Absolutely! Our baffles are designed to be versatile and can be used in various applications, including reservoirs and other large-scale water treatment areas. Our custom sizing and construction options ensure that our baffles can meet the unique requirements of your specific project.

Q: What materials are used in water baffle construction?
A:
At IEC, we use a variety of high-quality materials in the construction of our baffles. Most commonly used are raw materials such as stainless steel, XR-5, HDPE, potable water grade geomembrane  and HDG chain. The specific material used depends on the type of water, the baffles intended application, baffle length and depth.

Q: How do I maintain my baffles to ensure their longevity and effectiveness?
A:
Regular maintenance is generally not needed.  The materials used are UV resistant for longevity and long-term effectiveness.

Q: Can I order custom-sized baffles from IEC?
A:
Yes, we offer custom sizing options for all of our baffles to ensure that they perfectly fit your treatment area and meet your specific needs. Simply contact IEC with your requirements, and we will be happy to provide a quote for a custom-sized water baffle.
