Choosing the right heat exchanger for wastewater applications

Heat exchanger is one of the common concepts which is followed by both evaporators and crystallizers. Heat exchangers are most commonly used in the various applications in the water industry. Heat exchangers are also used in the aerobic digestion plant and in the anaerobic digestion plant, in the process of cooling, for the process of evaporation and crystallization and for the sludge concentration process. However, one of the toughest parts in the application of a heat exchanger is choosing the right type of heat exchanger for various applications. And when it comes to choosing the heat exchanger for wastewater applications, then you will have to keep a few things in mind.

For wastewater applications, it is essential that the heat exchanger should provide maximum productivity. Let’s take a look at some of the various points, through which the process of choosing the right heat exchanger would be easier for you.

How to check the productivity of the heat exchanger

Before understanding the productivity in the water industry, let’s discuss the basic meaning of productivity first. Productivity is the work efficiency of anything which is measured by getting the ratio of output of anything per unit of input. And when it comes to the water industry, productivity is considered as a balancing act. The main focus of the waste industry is to get the maximum output with the minimum investment of money possible. Therefore, the heat exchanger should provide optimum results for a longer period of time.

Understand the basic function of heat exchanger

The selection process of choosing the right type of heat exchanger involves knowing the specifications of the heat exchanger and on the basis of that deciding whether it will be suitable for the process of evaporation or crystallization or not. And to achieve this, it is very important that you should understand the materials used in the manufacturing of heat exchanger, the medium used in the process of heating and cooling and of course the knowledge of the whole procedure of heat exchanger, especially the concepts followed in the evaporators and crystallizers.

Do not go for the cheaper heat exchangers

This is one of the common mistakes done by various people, that they often go for those heat exchangers which are cheaper than others. However, it is very important that you should pay the total cost of ownership for getting maximum productivity of the heat exchanger. Most of the time, the operators can be manipulated because of low purchase prices at an initial stage. However, this could be a false economy. The operation cost of heat exchangers involves expensive and difficult materials used in the process such as sewage sludges. The costing of cleaning and maintenance are also very high in heat exchangers. Therefore, purchasing a cheap design could lead to spending more for the operations.

Energy-efficient

Energy efficiency plays a major role in the process of choosing the right type of heat exchanger for wastewater applications. As we discussed above, productivity is the key of a successful heat exchanger and energy efficiency helps in enhancing the productivity of the heat exchanger. There are various features in the heat exchangers, which help in improving the energy efficiency during the operations such as corrugated tubes, dti series and unicus series.

Regular maintenance

Like any other thing in the world, the regular maintenance of heat exchangers is very important and matters a lot. If you avoid the regular maintenance of each and every part of the heat exchanger, then later on the replacement of these parts will be very expensive. This will also help you in improving the lifespan of the heat exchangers. However, everything has a lifespan and when the time comes to replace the various parts of the heat exchanger, it is better that you should do it at the right time, otherwise it will be costlier for you to maintain and clean them.

Careful of hidden costs

It is very important that you should beware of the hidden costs involved at the time of purchasing the heat exchanger. You should discuss the overall installation cost of the heat exchanger and whether installing the heat exchanger will require some extra equipment to purchase or not. For example, the tube in tube heat exchangers are known for the better energy efficiencies but with smaller footprint. However, if we talk about the skid or frame mounted heat exchanger, then they require the support of infrastructure.

Therefore, the wrong type of heat exchanger could lead to the low-quality operation by decreasing the productivity of heat exchangers, especially for the processes of evaporation and crystallization.
