Solving Closed Cooling Water Corrosion Problems - OnePetro
Generally, a tight closed water system should not have more than a 1% water volume water loss per month. However, some process closed water systems have some planned water losses that must be reckoned with. The water treatment varies substantially for cooling water systems. Typical closed cooling water systems are shown in the following diagram.
Your facility’s closed system was designed to use water because it is available and efficient. In theory, this should be saving you money in lower energy and utility costs. But in reality, water-related problems rob you of these savings and compromise the reliability of your cooling. With the right help, preventing these problems is not hard.
Cooling Water Treatment
CORROSION INHIBITORS FOR COOLING WATER SYSTEMS. Corrosion deteriorates metal and reduces its thickness and strength that can result in leaks, contamination or equipment failures in the heat exchangers and recirculating cooling water pipes in open towers and closed loops.
Process Water; Closed Cooling Water System Treatment and Monitoring. Failure of a closed system has the potential to shut down a portion, if not all, of a plant’s operation. While closed cooling is suitable for many applications, neglect of water treatment and monitoring can lead to corrosion and fouling.

CLOSED LOOP WATER TREATMENT: Hot water, chilled water, tempered water, process water, and glycol filled closed loops are often ignored when considering a water treatment program, which can be a costly mistake. Closed loops that are not properly treated can cause significant corrosion damage.
Closed Loop Water Treatment Services Typical heating or cooling systems include three types of loops: a chilled water loop, a refrigerant gas loop and a cooling tower water loop. These types of closed loop systems are susceptible to leaks that can lead to contamination-forming corrosion and bacteria in the cooling water that may ultimately

ten fold change in acidic or caustic content. In closed recirculating water systems, corrosion of steel is minimized when pH is held at from 9.0-10.5. Should pH fall below 8.0, corrosion of steel will increase, corrosion inhibitor concentration may fall due to low pH chemical change of the inhibitor, and over time,

As the name “closed loop” suggests the intention is generally to retain the same water in the system for an indefinite period which means that without effective water treatment corrosion products and foulants can build up impairing flow and heat transfer and control valves can become blocked and inoperative.
Provide water treatment programmes that will mitigate against corrosion, deposition and biofouling, as per BSRIA BG50:2013. Quarterly monitoring services to evaluate and ensure delivery of an effective water treatment programme. System Health Checks on closed systems; chemical analysis of water samples with detailed report produced.

Fighting corrosion in closed loop system. Merus Rings are used in many closed loop systems. Corrosion is the biggest issue in the closed loop. If the water in closed loop is always in motion problems with corrosion are less. If the loop branches out in several sub loops, flow is not always given and so corrosion start.
Water systems that hold large volumes of water and remain idle for significant periods of time. These often promote the three problem factors above. Examples of this type of closed system include fire water systems and “post hydrotest” water for systems intended for normal closed or even open loop use.
- What is anaerobic wastewater treatment?
- Anaerobic treatment technology has emerged as one of the best treatment processes for different types of wastewater. Anaerobic lagoons are used for high strength organic wastewater, such as industrial wastewaters or a mixture of industrial and domestic wastewaters.
- Can anaerobic secondary treatment improve energy-positive operations at wastewater treatment plants?
- Cite this: Environ. Sci. Technol. 2025, 57, 45, 17225–17236 Anaerobic secondary treatment has the potential to facilitate energy-positive operations at wastewater treatment plants, but post-treatment of the anaerobic effluent is needed to recover dissolved methane and nutrients and remove sulfide.
- Can Anaerobic reactors be used in agro-industrial wastewater treatment?
- In countries like the Netherlands, almost all agro-industrial wastewaters are presently treated with anaerobic reactor systems. The application potential, e.g. in the petro-chemical industries, is rapidly growing. reactor volumes. no use of fossil fuels for treatment, saving about 1 kWh/kgCOD removed, depending on aeration efficiency.
- What are the advantages of anaerobic wastewater treatment?
- In comparison to the more traditional aerobic approach, the anaerobic process for waste and wastewater treatment has three inherent advantages: energy savings, lower sludge yield, and biofuel generation.
