Scale formation is a common problem in industrial recirculating water systems. As cooling water continuously circulates, evaporates and becomes concentrated, calcium, magnesium and other dissolved minerals may precipitate and form hard deposits on heat exchangers, pipelines, condensers and cooling tower components.
Common deposits include calcium carbonate scale, calcium sulfate scale, magnesium compounds and silicate scale. If not properly controlled, scale buildup can reduce heat transfer efficiency, restrict water flow and increase equipment cleaning and maintenance requirements.
Guanyu provides industrial recirculating water scale removal solutions according to water quality, circulation flow and operating conditions. For applications requiring continuous scale control, Circulating Water Electrochemical Descaling Equipment can be integrated into the circulating water loop to help remove scale-forming minerals before they accumulate on critical equipment.
Process Flow Example
A typical industrial recirculating water system consists of a circulation pump, heat exchanger, cooling tower, filtration system, scale control equipment and makeup water system.
The circulation pump delivers cooling water from the cooling tower or collection basin to the heat exchanger.
Cooling water absorbs heat generated by production equipment or industrial processes. As water temperature and mineral concentration increase, the risk of scale formation may also rise.
The heated water enters the cooling tower, where heat is released mainly through evaporation and air-water heat exchange.
Part of the circulating water can be directed through Circulating Water Electrochemical Descaling Equipment.
Through controlled electrochemical reactions, calcium, magnesium and other scale-forming minerals are encouraged to precipitate inside the treatment equipment instead of continuously accumulating on heat exchangers and pipelines.
The filtration system removes suspended solids, corrosion products and other particulate contaminants from the circulating water.
Fresh water is added to compensate for water lost through evaporation, blowdown and system discharge.
Depending on water quality and operating requirements, electrochemical scale removal can be combined with filtration, water-quality monitoring and other treatment processes to maintain more stable circulating water conditions.
Scale creates an insulating layer on heat-transfer surfaces. As deposits become thicker, heat exchange efficiency decreases and the cooling system may require more energy to maintain normal operating temperatures.
Scale accumulation inside pipelines and heat exchanger channels reduces the effective flow area and increases water resistance, which may affect circulation capacity.
Deposits can create localized conditions beneath the scale layer, increasing the possibility of under-deposit corrosion and localized equipment damage.
Severe scaling may require chemical cleaning, mechanical descaling or equipment shutdown, increasing maintenance workload and affecting production continuity.
Electrochemical treatment provides an effective technical option for controlling hardness-related scale in industrial circulating water systems.
When circulating water enters the electrochemical descaling equipment, an electric field is created between the electrodes.
Electrochemical reactions change the local conditions near the electrode surface and promote the precipitation of calcium carbonate and other scale-forming minerals.
Instead of allowing these minerals to continuously deposit on:
Heat exchangers
Condensers
Cooling pipelines
Cooling tower systems
Process cooling equipment
the scale is concentrated inside the electrochemical treatment unit, where it can be removed more conveniently.
This process helps reduce the scaling load on the overall industrial recirculating water system.
Guanyu Circulating Water Electrochemical Descaling Equipment is designed for industrial circulating cooling water systems where hardness and mineral concentration can cause recurring scaling problems.
The equipment can be installed as part of a side-stream treatment system and integrated with existing cooling towers, circulation pumps, filtration equipment and heat exchangers.
The equipment can operate continuously with the circulating water system, helping control mineral accumulation during normal production.
Scale-forming minerals are encouraged to precipitate inside the electrochemical treatment unit rather than on critical heat-transfer surfaces.
In suitable water conditions, electrochemical treatment can help reduce dependence on conventional scale-control chemicals.
The electrochemical descaling equipment can be integrated into new circulating water systems or added to existing industrial cooling-water installations.
According to project requirements, the system can be combined with conductivity, pH, hardness, flow and other water-quality monitoring instruments.
Equipment capacity and operating parameters can be configured according to actual circulation flow, hardness, conductivity, temperature and treatment requirements.

What causes scale in industrial recirculating water?
Scale usually develops when calcium, magnesium and other dissolved minerals become concentrated due to evaporation, temperature changes and changes in water chemistry.
What equipment is used for industrial circulating water scale removal?
Different methods can be used, including chemical dosing, softening, filtration and electrochemical descaling equipment. The appropriate solution depends on water quality and operating conditions.
What is Circulating Water Electrochemical Descaling Equipment?
It is equipment that uses controlled electrochemical reactions to promote the precipitation and removal of scale-forming minerals from circulating water, helping reduce scale accumulation on heat exchangers and pipelines.
Can electrochemical descaling reduce chemical consumption?
In suitable circulating water systems, electrochemical treatment can reduce dependence on conventional scale-inhibiting chemicals. However, corrosion and microbial control requirements should still be evaluated separately.
Can the equipment be added to an existing cooling tower system?
Yes. In many applications, electrochemical descaling equipment can be installed as a side-stream unit without fundamentally changing the existing circulating water process.
