All About Cooling Tower Makeup and Blowdown

Cooling towers use makeup water to replace the water lost through evaporation and blowdown, as shown in Figure 1 below.  Typically, city or well water is used.  The quantity and quality of these waters can be easily measured with water meters and analytical equipment.

Monitoring Ionic Balances in Cooling Towers

The term “cycles of concentration” is the basis for one of the most important concepts in industrial water treatment. The cycles of concentration measure the degree to which the solid impurities in the makeup water are concentrated in the recirculating water of an evaporative system. The higher this ratio, the more the impurities in the makeup water are being concentrated in the system water. This directly impacts the system’s water usage and treatment requirements along with the potential for waterside problems to occur, such as scale deposits and corrosion.

Increasing Water System Sustainability - Part 7:

Cooling towers, steam boilers, and recirculating closed loop systems require effective water treatment chemistry for reliable and efficient operation. Liquid treatment chemicals are traditionally used because they are easier to manufacture and add to systems, but liquids aren’t always the best fit and present safety and environmental concerns that are often overlooked.

The Importance of Managing Biofilm

Increasing Water System Sustainability - Part 6:

Where there is water, there is life. This includes cooling, chilled, process, and drinking water systems that facilities use every day. This life not only exists within the bulk water but sets up home on the surfaces of the water-related equipment, such as heat exchangers, piping, and basin walls. We call this deposit biofilm.

Increasing Water System Sustainability - Part 5:

The quality of water entering a boiler, cooling, or process system can have a significant impact on water, energy, and system efficiency. Raw makeup water can come with many different types of impurities, including dissolved and suspended solids, which can lead to energy-robbing scale deposits and equipment-damaging corrosion. Pretreatment equipment removes unwanted impurities from raw makeup water before they can cause problems in industrial water systems.

Increasing Water System Sustainability - Part 4:

Return on investment for a sustainable operation is linked to energy and water savings and ultimately the water treatment program. With increasing energy costs and water scarcity concerns, more than ever, pressure is being placed on facility managers to find ways to reduce usage.
An effective water treatment program is a critical part of the preventative maintenance of boiler and cooling systems. In many cases, the water treatment program can be engineered to improve energy and water efficiency, reduce chemical usage, and optimize results. Automating blowdown, chemical feed and control, and other treatment processes can effectively help make a water treatment program more sustainable.

Increasing Water System Sustainability - Part 3:

Water and energy go hand in hand. It takes energy to pump, treat, heat, and cool water for boiler and cooling systems. Not only can optimizing water usage help minimize energy usage, but managing scale deposits, corrosion, and biofilms also play a role in energy demands.

Boiler and cooling water systems require substantial amounts of energy to run our modern-day world. Proper water management can help reduce and optimize these energy demands. Multiple strategies are available to help meet energy-saving objectives, including optimizing water chemistry, improved pretreatment, preventing scale deposits, reducing water waste, and equipment maintenance.

Water is an ultimate sustainable resource. The hydrologic cycle works to continuously return water to nature for reuse. The challenge is to find enough usable water without overtaxing nature’s ability to replenish the local water supply. 

As a large consumer of fresh water, boiler and cooling systems are obvious targets for water conservation efforts. When properly managed, reducing water usage for these systems can have the added benefit of reducing the total costs of operation. There are multiple strategies to help meet water-saving objectives, including management and control of water chemistry, makeup water pretreatment, use of alternative water sources, and equipment maintenance.

Increasing Water System Sustainability - Part 1:

As the global population grows and the demand for water, energy, and other natural resources increase, it is important to responsibly manage and use all our resources wisely. An effective water treatment program helps maximize the life, efficiency, reliability, and safety of boiler, cooling, closed loop, and wastewater systems and minimizes water usage, energy demand, greenhouse gas emissions, and total costs.
