The term "Micro-Matic" in the context of environmental and water treatment often refers to a specific type of rotating microscreen developed and manufactured by USFilter, now known as Industrial Wastewater Systems (IWS). These screens represent a significant advancement in the field of wastewater treatment, offering a reliable and efficient solution for solids removal.
How Micro-Matic Screens Work
Micro-Matic rotating microscreens are comprised of a drum with a fine mesh screen surface, typically made from stainless steel. The drum rotates slowly in a tank filled with wastewater. As the drum rotates, the screen surface passes through the water, capturing suspended solids. The captured solids are then removed from the screen by a rotating brush or a high-pressure water jet.

Scenario: A municipality is considering installing a Micro-Matic rotating microscreen for pre-treatment of its wastewater before it enters a membrane filtration system. The goal is to protect the membrane system from clogging and extend its lifespan.
Task:
Here are three benefits of using a Micro-Matic screen in this scenario:
1. **High Solids Removal Efficiency:** Micro-Matic screens can effectively remove a wide range of suspended solids, including particles as small as 20 microns. This is crucial for protecting membrane systems as these small particles can easily clog the membranes, reducing their efficiency and lifespan.
2. **Minimal Headloss:** The design of the Micro-Matic screen minimizes headloss, ensuring efficient water flow through the system. This is important for pre-treatment as it prevents excessive pressure on the membrane filtration system, which can damage the membranes and reduce their lifespan.
3. **Reduced Maintenance:** The automated cleaning mechanism of Micro-Matic screens minimizes the need for manual cleaning and reduces downtime. This is crucial for a continuous water treatment process, ensuring that the membrane system is not exposed to excessive amounts of solids due to system downtime.
The term "Micro-Matic" typically refers to a type of rotating microscreen developed by USFilter, now known as Industrial Wastewater Systems (IWS). This technology revolutionized wastewater treatment by offering a highly efficient and reliable solution for solids removal.
Micro-Matic screens utilize a rotating drum with a fine mesh surface, often made of stainless steel. This drum slowly rotates within a tank filled with wastewater. As the drum turns, the screen surface continuously passes through the water, capturing suspended solids. These captured solids are then removed from the screen by a rotating brush or a high-pressure water jet, ensuring continuous operation.
The use of Micro-Matic screens offers numerous advantages, including:
IWS offers a variety of Micro-Matic screen models, each tailored for specific applications and flow rates. Some common models include:
Micro-Matic screens are typically constructed using high-quality stainless steel for the drum and screen mesh. This ensures durability and resistance to corrosion, extending the lifespan of the equipment. The choice of material may vary depending on the specific application and the nature of the wastewater being treated.
Micro-Matic screens employ either a rotating brush or a high-pressure water jet for cleaning the screen surface. The choice of cleaning mechanism depends on the type of solids being removed and the desired level of cleanliness.
Micro-Matic screens often incorporate advanced control systems and monitoring capabilities. These systems ensure efficient operation and provide real-time data on performance, such as flow rate, pressure, and solids capture efficiency.
The control systems can collect data on various parameters related to the screen's performance, enabling the operators to monitor and optimize the system. This data can be used for trend analysis, troubleshooting, and identifying potential areas for improvement.
Advanced control systems can automate various processes, including cleaning cycles, flow rate adjustments, and alarm notifications. In some cases, remote access to the control system can enable remote monitoring and troubleshooting, further enhancing operational efficiency.
Choosing the appropriate Micro-Matic screen model is crucial for optimal performance. Factors to consider include:
Proper installation and operation are essential for maximizing the efficiency and lifespan of Micro-Matic screens. It is recommended to:
Ongoing optimization and troubleshooting are crucial for maximizing the performance and longevity of Micro-Matic screens. Some key strategies include:
Micro-Matic screens have been successfully implemented in numerous wastewater treatment applications worldwide. Here are a few examples:
