Combined sewer systems, common in older cities, pose a significant environmental challenge. During heavy rainfall, these systems can overflow, discharging untreated wastewater and debris directly into waterways, polluting our rivers and lakes. Hydroclean, a revolutionary technology, offers a solution to this problem through efficient and reliable fine screening of combined sewer overflows (CSOs).
Grande, Novac & Associates, Inc. (GNA), a leader in environmental engineering, specializes in the design and implementation of Hydroclean systems. These systems employ high-capacity screens that effectively remove debris and solids from CSOs before they reach waterways. This process significantly reduces the environmental impact of these overflows, protecting aquatic ecosystems and improving water quality.

Chapter 1: Techniques
Hydroclean utilizes advanced fine screening techniques to effectively manage combined sewer overflows (CSOs). The core technology revolves around high-capacity, self-cleaning screens designed to remove debris as small as 2 millimeters from wastewater flows. These screens are not simply static barriers; they employ several key techniques to maximize efficiency and minimize maintenance:
Screen Material and Design: The choice of screen material is crucial for strength, durability, and the ability to effectively capture fine particles. Materials may include stainless steel or other corrosion-resistant options depending on the specific characteristics of the wastewater. Screen design incorporates optimized mesh sizes and geometries to balance effective particle capture with minimal clogging.
Self-Cleaning Mechanisms: Hydroclean systems employ automated cleaning mechanisms to prevent screen clogging and maintain continuous operation. These mechanisms typically involve rotating brushes, pressurized water jets, or a combination of both. The cleaning cycle is automated and optimized to remove accumulated debris without interrupting the flow of wastewater.
Debris Handling: The collected debris is efficiently removed from the screen and transported to a designated collection point for further processing or disposal. This may involve a conveyor system, a screw auger, or other appropriate methods depending on the volume and type of debris collected.
Flow Management: Sophisticated flow control systems are integrated to manage the variable flow rates characteristic of CSOs during rainfall events. This ensures that the screens operate efficiently even during periods of high flow, preventing overflow and maintaining effective pollutant removal.
These techniques work in concert to ensure the robust and reliable performance of Hydroclean systems, delivering consistent and high-quality CSO treatment.
Chapter 2: Models
Hydroclean systems are not "one-size-fits-all." Several models exist, tailored to the specific needs and conditions of each installation site. Factors influencing model selection include:
Flow Capacity: Different models are designed to handle varying flow rates, from smaller, localized CSOs to large-scale systems servicing entire urban areas.
Debris Characteristics: The composition and volume of debris expected in the CSO influence screen design and cleaning mechanism selection. Systems handling high concentrations of grit or fibrous materials may require more robust cleaning mechanisms.
Site Constraints: Space limitations, access restrictions, and existing infrastructure all influence the choice of Hydroclean model. Modular designs allow for flexible configuration to fit into challenging site conditions.
Budget and Regulatory Requirements: The budget allocated for the project and the applicable environmental regulations significantly impact the selection of a suitable Hydroclean model. Cost-effective solutions are available to meet a variety of budgetary constraints.
Examples of Hydroclean models might include:
GNA works collaboratively with clients to select the optimal Hydroclean model, considering all relevant factors to ensure the most effective and sustainable solution.
Chapter 3: Software
The design and operation of Hydroclean systems benefit from sophisticated software tools. These tools are integral to:
Hydraulic Modeling: Software is used to model the hydraulic performance of the system under various flow conditions, ensuring optimal design for efficient CSO treatment. This modeling considers factors such as inflow rates, screen capacity, and backwater effects.
Control System Integration: Software plays a critical role in managing the automated cleaning cycles and flow control systems. This ensures efficient and uninterrupted operation of the Hydroclean system.
Data Acquisition and Monitoring: Software is crucial for collecting and analyzing data on system performance, including flow rates, debris accumulation, and cleaning cycles. This data provides valuable insights into system efficiency and helps in optimizing operations.
Predictive Maintenance: By analyzing operational data, software can help predict potential maintenance needs, allowing for proactive interventions and minimizing downtime.
GNA utilizes state-of-the-art software packages specifically designed for CSO management and wastewater treatment systems. This ensures that the Hydroclean systems are designed and operated with maximum efficiency and reliability.
Chapter 4: Best Practices
Implementing a Hydroclean system successfully requires adherence to best practices throughout the project lifecycle:
Thorough Site Assessment: A comprehensive assessment of the CSO characteristics, flow rates, debris composition, and site conditions is essential for proper system design.
Collaboration and Communication: Effective communication and collaboration between engineers, contractors, and municipal stakeholders are critical to successful project implementation.
Proper System Integration: Seamless integration of the Hydroclean system with existing infrastructure is crucial for optimal performance and minimal disruption to existing operations.
Comprehensive Operator Training: Providing thorough training to operators on system operation, maintenance, and troubleshooting ensures efficient and long-term system performance.
Regular Maintenance and Inspection: Implementing a regular maintenance schedule and performing routine inspections helps prevent potential problems and ensures continuous system performance.
