Knowledge

Process cooling water frequently has pollutants including bacteria, dissolved minerals, suspended particles, and other microorganisms in it. These impurities might cost a lot of money to fix if they are not filtered out of the system.

Facility operations that utilize process cooling water must have an effective filtration system to ensure the longevity of their equipment. Without proper filtration, cooling water can become fouled and be much less efficient at eliminating heat from devices. This can lead to potential overheating, scaling, corrosion, and bacterial growth in piping and cooling towers — all costly risks. In order to minimize these problems, it is important to invest in a reliable filtration system that will keep process cooling water clean.

No matter the industry or particular industrial application, blockages lead to ineffective systems. Chillers, cooling towers, and process cooling water are not any different in this regard. Let’s discuss what you need to know about filtration and process cooling water.

Virtually all water sources available for cooling require some filtration

Airborne pollutants (such as debris, sand, pollen, and other suspended solids) can easily contaminate water supplies such as cooling towers, recycled water, and surface water. Moreover, pipe scale and corrosion byproducts have the potential to pollute all of these water sources.

When there are pollutant deposits in the system, it will damage the sensing surface of internal equipment compressors, coolers, heat exchangers, etc., resulting in a decrease in heat transfer efficiency and an increase in pressure loss. The final result is that more cooling water needs to be pumped to achieve the purpose of cooling, which will only cause excessive consumption of water and waste of energy.

The filtration of the process cooling water is particularly easy to be neglected, but the cleanliness of the cooling water directly affects the productivity and profitability of the entire system operation and the comfort of the working environment. Cooling water filtration is essential, after all, contamination of pipes and heat exchange surfaces can lead to the following consequences:

  • Rising energy costs
  • Reduced productivity
  • Increase in chemical costs
  • The dramatic increase in water consumption
  • Increased maintenance of system facilities and equipment

How does water filtration work for process cooling water?

Filtration systems are one of the most common water treatment systems used in cooling towers. Among them, the filter is used to filter out pollutants in the water, and the specific type and model must be selected according to the specific application. The essence of filtration is to let water pass through smaller and smaller spaces, blocking out large particles such as sediment, rust, and organic matter. Each filter has holes, and different filters have different pore sizes.

However, particulate pollutants that are smaller than the gap will still pass through with the water flow, and ultrafiltration is particularly important in the filter system at this time. As more than one filter is used in the filtration system, its limitation of pollutants will become more and more. Even if some contaminants pass through the larger pore filter, they are still captured in the subsequent filtration process.

Benefits of cooling water filtration

Industrial processes are inseparable from cooling water, and its water quality should also arouse people’s great attention. Cooling water filtration is very necessary and keeping the process cooling water clean supports the better operation of the industrial systems involved. The accumulation of impurities in water often leads to corrosion and scaling of equipment. Not only reduces the working efficiency of equipment but also increases its downtime and maintenance costs.

Reduce maintenance costs

The filter can filter the pollutants before they enter the system, which reduces the maintenance and repair time and cost of the system. Impurities in the water supply system can cause damage to equipment, and the filtration system helps reduce the wear and tear on equipment. At the same time, it can also prevent the formation of fouling problems in the equipment, which hinders the operation of industrial systems.

Save industrial water consumption

Water is the source of life, so we should try our best to use water in an environmentally friendly way. Industrial processes often consume large amounts of water. Filters are an effective facility use of resources and water reuse to reduce water consumption. The used water can still be used repeatedly after being filtered. Over time, it not only realizes the water cycle but also reduces the adverse impact on the environment.

Prevent damage to cooling equipment and its components

Filtration can play a protective role in cooling water equipment, which can effectively block debris impurities and reduce damage to equipment. Filters are direct and effective at removing task pollutants, impurities, and larger particles from water. If the equipment is blocked by impurities, the cooling capacity will be reduced, and equipment failure or overheating will occur.

Filtration Solutions and Maintenance Tips

Choosing the right and effective process cooling water filtration system is an important part of optimizing industrial productivity. The selection of the cooling water process filtration system requires multi-dimensional considerations in order to select the optimal filtration solution. Here are a few considerations related to cooling water process filtration:

Cooling water process coolant sources

Cooling water comes from natural water bodies and is treated by chillers. The cooling liquid requires strong filtering equipment for filtration. Both filters and coalescers are used to deal with impurities in large volumes of fluids.

Cooling water may contain organic or inorganic solid pollutants

The nature of the contaminants in the fluid

The nature of pollutants in cooling water will affect the overall system operation. Cooling water may contain organic or inorganic solid pollutants, which requires targeted filtration with different filters.

Operating system temperature and pressure levels

Process temperature and pressure levels are generally dependent on the choice and application of the industrial manufacturing system. Higher temperature and pressure levels in processing systems require a greater degree of cooling and a correspondingly wider range of filtration systems.

Allowable system downtime for maintenance

Before you choose an industrial cold water filtration system, determine its maintenance downtime. And during the operation of the system, the manufacturer’s maintenance recommendations are adopted and implemented to ensure that the system can always run smoothly.

Allowable system downtime for maintenance

Reduce the installation and maintenance costs of filtration system equipment

Purchase and use of industrial application equipment. Both short-term and long-term cost implications must be considered. The same goes for the filtration system, considering the overall long-term maintenance cost and output of the filtration system for industrial cooling water.
