Chapter 1: Techniques

Lakos Screen Technology: A Closer Look

Lakos screens employ a unique combination of mechanical and hydraulic principles to achieve efficient and reliable debris removal. The core of this technology lies in the self-cleaning mechanism, which plays a pivotal role in ensuring continuous operation and minimal maintenance requirements.

Self-Cleaning Mechanism:

The self-cleaning mechanism typically involves a rotating brush or a pressurized water jet. The brush sweeps across the screen surface, dislodging accumulated debris, while the water jet washes away the collected particles. This process occurs automatically at regular intervals, ensuring the screen remains free of blockages.

Filter Media:

The choice of filter media is crucial for the effectiveness of Lakos screens. The media can range from stainless steel mesh to synthetic fabrics, each offering specific filtration capabilities based on pore size and material properties. This allows for customization to address various debris sizes and water quality challenges.

Advantages of Lakos Screen Techniques:

• Continuous Operation: The self-cleaning mechanism ensures uninterrupted water flow, minimizing downtime and production disruptions.
• Reduced Maintenance: Automated cleaning eliminates the need for manual intervention, minimizing labor costs and maintenance requirements.
• High Efficiency: The screens effectively capture a wide range of debris, minimizing the risk of downstream equipment damage.
• Adaptability: Various filter media and screen sizes allow for customization to suit diverse applications.

Types of Lakos Screens:

• Self-Cleaning Pump Intake Screens (IPC): These screens are specifically designed for use in pumping applications, protecting pumps from clogging and wear.
• Trash Racks: These screens are larger and handle larger debris, typically used in open water intake structures.
• Fine Mesh Screens: These screens offer extremely fine filtration, suitable for applications requiring high water purity.
