Helico: A Powerful Tool for Environmental & Water Treatment

In the realm of environmental and water treatment, the term "Helico" often refers to a specific technology employed for solids removal and dewatering – the Helico Screw Type Screenings Press. Developed by Infilco Degremont, Inc., this system is a crucial component in wastewater treatment plants, industries, and even municipal water systems.

What is a Helico Screenings Press?

A Helico Screenings Press is a robust, reliable machine designed to efficiently remove and dewater screenings – the solid waste collected from raw sewage or other industrial wastewater streams. It operates using a screw press mechanism, efficiently extracting water from the screenings while compacting them into a manageable solid mass.

Key Features and Benefits:

  • Efficient Dewatering: The screw press technology effectively reduces the moisture content in screenings, significantly minimizing the volume of waste to be disposed of.
  • Reduced Handling Costs: The compacted screenings require less handling and transportation, making the entire process more efficient and cost-effective.
  • Reduced Odor and Environmental Impact: By minimizing the volume and moisture content of screenings, the Helico Press significantly reduces odor emissions and potential environmental impacts.
  • Durability and Reliability: Built with high-quality materials and robust construction, the Helico Press is designed for long-term operation with minimal maintenance requirements.
  • Flexibility: The system can be customized to meet specific needs and capacity requirements, making it suitable for a wide range of applications.

Working Principle of the Helico Press:

  1. Screening: Wastewater is initially passed through a screen, capturing solid debris (screenings).
  2. Conveying: The collected screenings are then conveyed to the Helico press.
  3. Compaction: The screenings enter a rotating screw press that gradually compacts and dewaters the material.
  4. Discharge: The dewatered screenings are discharged as a compacted solid mass, ready for disposal.

Applications in Environmental & Water Treatment:

The Helico Screenings Press finds applications in various sectors, including:

  • Wastewater Treatment: Removal of screenings from raw sewage in municipal wastewater treatment plants.
  • Industrial Wastewater Treatment: Efficient handling of screenings generated in industries like food processing, pulp and paper, and manufacturing.
  • Stormwater Management: Removal of debris from stormwater runoff.
  • Water Treatment: Removal of suspended solids from raw water sources.

Conclusion:

The Helico Screenings Press plays a critical role in efficient and environmentally responsible water and wastewater treatment. By effectively removing and dewatering screenings, it contributes to optimized treatment processes, reduced disposal costs, and minimized environmental impact. As a reliable and efficient technology, the Helico Press remains a valuable tool for promoting sustainable water management practices.

The Helico Screw Type Screenings Press: A Detailed Look

The Helico Screenings Press utilizes a screw press technology to efficiently dewater screenings collected from wastewater streams. This technique involves several key components working in synergy:

1. Screening: The first step involves passing wastewater through a screen, capturing solid debris known as screenings. This screen can be designed with various mesh sizes to accommodate different types of screenings.

2. Conveying: Once captured, the screenings are conveyed to the Helico press. This is typically done through a system of conveyors or chutes.

3. Compaction: The heart of the Helico press lies in the rotating screw press. This mechanism gradually compacts the screenings, pushing water out through perforations in the screw's casing.

4. Discharge: The dewatered screenings, now a compacted solid mass, are discharged from the press. This discharge system can be customized for various disposal methods.

Key Advantages of the Screw Press Technique:

  • High Efficiency: The screw press effectively removes moisture from screenings, minimizing their volume and weight.
  • Reduced Handling: Compact screenings require less handling and transportation, streamlining the entire process.
