Efficient cooling and chilling is an essential part of energy transfer for multiple applications across industries and communities. Changing planetary temperatures have created a greater need for comfort cooling, while increased demand for consumer goods from growing populations requires robust process cooling procedures.
The key to consistent, sustainable and efficient processes within cooling towers, heat exchangers and cooling systems is high-quality water. It is their life-blood.
With the help of Marlowe Environmental Services, our customers can be confident that high-quality water will minimise waste, while reducing any negative financial or environmental impacts.
Meaning you and your systems can concentrate on delivering the highest comfort, production or environmental standards without breaking a sweat.
Because every cooling tower water treatment programme is unique, the challenge for many of our customers is understanding the innate complexity of cooling and chilled systems. It’s why our team at Marlowe Environmental Services are passionate about sharing our knowledge and experience of working with these systems, while helping to further educate you, our customers, at every step of the journey. Increasing your confidence and understanding of your cooling system, and the quality of your water supply.
It’s important for us to do this with you, because an effective cooling water treatment programme ensures safety and efficiency. We do this by keeping the water used in cooling systems in excellent condition, free of bacteria, and in a state where the risk of corrosion is minimal.
Water sources, including reuse water, and their levels of ions and microbiological populations vary between facilities. This is why cooling tower operating conditions, including temperature, sizes, flows, materials of construction, and process variation are different with every customer. And why our bespoke offering and hands-on experience with these incredibly important systems is so valued.
There are several common cooling tower water issues that Marlowe Environmental Services can help resolve:
At Marlowe Environmental Services, we are committed to working with our customers to not only reduce running costs of cooling and chilled systems, but also to reduce their environmental impact with Corporate Social Responsibility firmly in mind.
We do this with unrivalled water quality, maximising efficiencies, offering bespoke automated and remote monitoring tools, while implementing cooling tower bleed recovery systems to reduce waste sent to drain. As part of this commitment, Marlowe Environmental Services has developed an industry-leading cooling tower bleed recovery system that recovers a portion of the bleed water to reuse as make-up water. Saving customers significant amounts of money by reducing the OPEX of cooling plants.
In addition, Marlowe Environmental Services offers an innovative range of bespoke cooling system services and engineered products to complement chemical and monitoring programs for cooling systems. These include:
Packaged pre-treatment: water softeners, water distribution, and ion-exchange systems.
Chemical dosing and control systems, including remote chemical usage and level monitoring.
Biofilm and scale monitoring systems, linked to automatic dosing for live remediation.
Cooling tower bleed recovery systems, to capture and reuse cooling tower wastewater.
Cooling tower refurbishments and upgrades.
Untreated or poorly treated water can lead to corrosion, biological growth, scale and fouling—all of which reduce heat-exchange efficiency, increase energy consumption and pose safety risks. Effective water treatment keeps systems clean, efficient and compliant.
Most systems require continuous monitoring via automated equipment plus routine site inspections by trained technicians. Frequency depends on system size, water source and risk profile, but weekly or monthly site checks are common.
Warm water, stagnation, nutrient availability and poor control of biocides can create ideal conditions for Legionella bacteria. A robust, compliant water treatment regime and regular system maintenance greatly reduce this risk.
Yes. Every cooling system is different, and our engineers create tailored programmes based on water quality, system design, operational demands and environmental considerations.
Bleed recovery involves capturing the water normally discharged from the tower to control TDS levels, treating it and re-using it as make-up water. This reduces total water consumption and OPEX.
Indicators include unusual odours, visible scale, reduced cooling efficiency, rising energy costs, drifting water quality parameters, or increases in corrosion rates. Regular monitoring helps detect issues early.
Absolutely. Automated and remote-monitoring systems optimise chemical dosing, track system health in real time and allow quick responses to changes—minimising waste, preventing faults and reducing labour costs.
Pre-treatment (such as softening, filtration or ion-exchange) is recommended when raw water quality is poor or when specific ions and contaminants could accelerate scaling, corrosion or fouling.
