The term "satellite" in environmental and water treatment typically refers to a specific type of reactor configuration, often utilized in biological wastewater treatment. These systems are characterized by the use of fixed-film reactors, where microorganisms attach themselves to a stable surface (the "film") and utilize the flowing wastewater for their metabolic processes. This leads to the removal of pollutants and the purification of the water.
One of the key components within these fixed-film reactors is the rotary distributor, a device responsible for evenly distributing the wastewater across the film surface. This ensures optimal contact between the wastewater and the microbial population, maximizing treatment efficiency.

This expanded document delves deeper into the specifics of satellite-based wastewater treatment systems, focusing on Simon-Hartley's electrically driven rotary distributors. We'll explore the techniques, models, software, best practices, and case studies associated with this technology.
Simon-Hartley's electrically driven rotary distributors utilize several key techniques to achieve efficient wastewater treatment:
Fixed-Film Bioreactors: The core principle relies on the attachment of microorganisms to a fixed media surface (the film). This allows for high biomass concentration and efficient pollutant removal. The technique optimizes the contact time between wastewater and microorganisms, leading to higher treatment efficiency compared to suspended growth systems.
Uniform Wastewater Distribution: The rotary distributor's primary function is the even distribution of wastewater across the media surface. This ensures all areas of the biofilm are exposed to wastewater, preventing dead zones and maximizing treatment efficiency. The electrically driven system allows for precise control of distribution, unlike gravity-fed systems which are susceptible to uneven flow.
Controlled Aeration (if applicable): Depending on the specific design and treatment requirements, aeration can be integrated into the system. This provides oxygen to the microorganisms, supporting their aerobic metabolic processes and enhancing pollutant removal. The control of aeration is often integrated with the distributor's control system, optimizing oxygen supply based on wastewater flow and treatment demands.
Recirculation: In some installations, recirculation of treated effluent may be incorporated to further optimize treatment, particularly in situations with high pollutant loads or demanding treatment goals. This enhances the contact time and treatment efficiency.
Simon-Hartley offers various models of electrically driven rotary distributors, tailored to meet diverse treatment needs and plant capacities. While specific model details would require consultation with Simon-Hartley, the variations are likely to involve:
Size and Capacity: Distributors come in various sizes, depending on the diameter of the fixed-film reactor and the required wastewater flow rate. Larger distributors are needed for higher capacity treatment plants.
Motor Power: The power of the electric motor is selected based on the distributor's size and the expected load. Higher power motors ensure efficient operation even under high flow conditions.
Materials of Construction: Different materials (e.g., stainless steel, polymers) may be used depending on the wastewater characteristics and environmental conditions. Corrosion resistance is a key consideration.
Control System Integration: Advanced models may include sophisticated control systems for automated operation, data logging, and remote monitoring. These systems can optimize energy consumption and treatment performance based on real-time data.
While Simon-Hartley may not provide dedicated software for managing their distributors in every installation, the systems often integrate with Supervisory Control and Data Acquisition (SCADA) systems used in wastewater treatment plants. These SCADA systems provide:
Optimal performance of Simon-Hartley's electrically driven rotary distributors requires adherence to best practices including:
Regular Maintenance: Scheduled inspections and maintenance are crucial to prevent malfunctions and ensure longevity. This includes lubrication, inspection of motor and gearbox components, and cleaning of the distributor arms.
Proper Installation: Correct installation is critical to ensure even distribution and efficient operation. This involves careful leveling and alignment of the distributor and proper connection to the wastewater flow system.
Operational Optimization: Regular monitoring of system parameters and adjustment of the distributor's speed allows optimization of treatment efficiency and energy consumption.
Biofilm Management: Maintaining a healthy and active biofilm is essential for effective treatment. This involves monitoring biofilm growth and implementing strategies for cleaning or replacing the media if necessary.
Preventive Maintenance: Proactive maintenance scheduling based on usage and environmental factors prevents unexpected downtime and extends equipment lifespan.
