Waste water as a valuable heat source
Waste water contains untapped heat. In municipal wastewater plants, it is not only part of water treatment but also a valuable energy source. With the right technologies, this heat can be harnessed and used for district heating grids or industrial processes. Heat pumps play a key role here by raising the temperature to a usable level. This makes waste water a key component of a sustainable heat supply and for reducing CO₂ emissions and energy costs.
Utilizing heat and managing risks
If you want to utilize heat from waste water economically and reliably, you need to consider the system as a whole. Indeed, it is crucial that the entire water-carrying system is managed reliably. A wide range of factors need to be taken into account when using waste water: temperature, flow rate, water quality, seasonal fluctuations, heat exchanger technology, and integration into existing infrastructures. The properties of the waste water, in particular, place high demands on evaporators and heat exchangers. Microfouling and macrofouling can significantly impair the efficiency and availability of the plant depending on the composition and operating conditions. All this takes a toll on energy efficiency. Typical cost drivers include biofouling, sedimentation, crystallization, and corrosion, as well as algae, foliage, plastic waste, and other large items of debris.
Clean systems and stable performance
TAPROGGE Solutions
Concepts that are tailored to the specific requirements of waste water are required in order to utilize the heat efficiently. This is precisely where our filtration and tube cleaning solutions for heat exchangers and evaporators come in. They help to tackle fouling typically found in waste water early on, prevent energy loss, and ensure long-term efficient operation. The aim is to control fouling typically found in waste water early on, keep the heat transfer stable, and ensure ongoing plant availability.
Below are some examples of solutions for these specific requirements:
Backwashable filters
These filters are available in different series and protect downstream components such as evaporators and heat exchangers from macrofouling and clogging as a prefiltration solution.
Taprogge Systems
These are equipped with backwashable strainers and reliably prevent microfouling in evaporator and heat exchanger tubes. The aim is to keep the heat transfer coefficient of the heat exchanger as close as possible to the initial value using Taprogge Cleaning Balls that are specially tailored to the tube type and operating conditions.
