A wastewater heat exchanger transfers heat between wastewater and another process fluid without the two fluids coming into direct contact.
Depending on the application, it can be used to recover heat from warm wastewater, cool process water before discharge, or maintain more consistent temperatures throughout a treatment process. Recovering this otherwise wasted thermal energy can also help reduce the amount of additional heating or cooling required elsewhere in the system.
Heat exchangers are commonly used in wastewater treatment plants, sludge heating systems, anaerobic digestion, thermal hydrolysis, effluent cooling, waste heat recovery and water reuse applications.
They may be incorporated at different stages of the wastewater process depending on the required temperature change. For example, heat exchangers can help preheat sludge before digestion, recover energy from outgoing process streams, cool treated effluent, or transfer heat between process fluids to improve overall system efficiency.
Yes. Heat exchangers can be designed for wastewater streams containing suspended solids, sludge, and other challenging materials.
Applications involving high solids content generally require heat exchangers with suitable flow passages and configurations that minimise blockages and fouling. Factors such as particle size, viscosity, solids concentration, flow rate, and cleaning requirements should therefore be considered when selecting the most appropriate heat exchanger.
Wastewater can retain a significant amount of thermal energy after a process is completed.
Instead of allowing this energy to be discharged with the wastewater, a heat exchanger can transfer some of the available heat to another process stream. This recovered energy may then be used to preheat water, sludge, or other fluids, potentially reducing the demand on boilers, heaters, or cooling equipment.
Key considerations include wastewater temperature, flow rate, solids content, viscosity, pressure, required heat-transfer duty, corrosion risk, fouling potential, available space, and maintenance requirements.
The physical and chemical characteristics of the wastewater are particularly important because they influence the heat exchanger configuration, materials, and flow passage design. Considering these conditions early can improve heat transfer performance and facilitate easier cleaning, inspection, and ongoing maintenance.
Fouling can be managed through appropriate heat exchanger selection, suitable flow velocities, larger flow passages, effective system design, and regular inspection or cleaning.
The ideal approach depends on the wastewater composition and the type of contaminants present.
Selecting a heat exchanger that maintains suitable fluid velocity and provides adequate access for cleaning can help reduce deposits, maintain heat transfer efficiency and minimise unnecessary downtime.
Teralba can provide a range of heat exchanger solutions for wastewater applications, including tube-in-tube, shell-and-tube, tri-tube, and Coilflo heat exchangers.
Different configurations can suit different wastewater conditions, including streams with varying solids content, viscosity, temperature, and flow requirements. Teralba can review the process conditions and recommend a heat exchanger solution based on the required heat transfer performance, operating environment, and maintenance requirements.
Yes. Teralba can assess factors such as solids loading, temperature, flow rate, pressure, corrosion requirements, and fouling risk to recommend a heat exchanger configuration suited to the application.
This can include considering appropriate materials of construction, flow passage sizes, and heat exchanger configurations for challenging industrial environments. The aim is to provide a solution that achieves the required thermal performance while also considering reliability, accessibility and ongoing maintenance.
Yes. Teralba can assist with heat exchanger selection for waste heat recovery applications where thermal energy from wastewater or process streams can be transferred and reused elsewhere in the system.
By reviewing the available temperatures, flow rates, and process requirements, Teralba can identify opportunities to transfer otherwise unused heat to another part of the process. This may help reduce heating or cooling demand while improving the overall efficiency of the wastewater system.
Provide Teralba with available process information, including fluid type, inlet and target temperatures, flow rates, pressure conditions, and solids content.
The more information available about the process conditions, the easier it is to determine an appropriate heat exchanger configuration. Details such as materials compatibility, fouling characteristics, available space, and cleaning requirements can also help Teralba recommend a solution suitable for the specific wastewater application.
