Reducing water use through reuse & water recycling
Like it or not water is becoming an increasingly scarce resource in many parts of the world as climates change, populations increase and the demands for good quality water become ever greater.
The challenge now facing organisations is how to optimise their use of this scare resource.
Opportunities to do this might include new water conservation strategies, identifying innovative ways in which to treat wastewater and industrial effluents, water recycling, rainwater harvesting and improving overall water and energy efficiencies.
Reducing water use through conservation and recycling
Reducing the volumes of water used in commercial, institutional and industrial buildings, and manufacturing and process applications requires a detailed appreciation of how the water is used and its impact on each process.
This can include the use of hot and cold water in buildings, heating and cooling systems through to complex industrial processes.
Our expert team have the knowledge and experience to identify key areas for reducing overall water consumption, advising on best practice, the latest water saving devices, industry bench-marking and performance monitoring.
Industrial wastewater and effluent
Optimising the treatment of industrial wastewater and trade effluent is becoming ever more complex as increasingly rigorous environmental standards become the norm, and energy, water and effluent discharge costs increase.
Under such challenging conditions improving the treatment processes for industrial wastewaters becomes ever more important.
Our team of experts offer a holistic approach to the evaluation and treatment of industrial wastewaters and developing innovative ways to reduce costs, improve process and energy efficiencies along with the introduction of new, eco-friendly wastewater recycling and water reuse solutions.
This allows us to help customers meet their legal obligations in the most economic, environmentally sensitive way, improve waste management processes and protect the environment.
Rainwater harvesting and greywater recycling
Rainwater harvesting and greywater recycling present excellent opportunities to collect or recycle water for alternative uses.
To develop the most appropriate water reuse solution it is essential to understand the technologies involved in these applications, where the water can be reused and how it needs be treated to meet water quality standards.
Water Treatment Services combine our water treatment expertise with a practical engineering approach to design, construct and manage the most appropriate rainwater harvesting and greywater recycling solutions for each application.
HVAC energy efficiency
Heating, ventilation and air conditioning systems, often abbreviated to HVAC are complex building systems designed to control the temperature, humidity, and air quality in indoor spaces.
Well-designed HVAC systems will help to create desired levels of thermal comfort and indoor air quality.
Our energy efficiency services seek to optimise the performance of HVAC systems by reviewing comfort, climate control, and output quality and energy efficiency issues.
Key areas for investigation and HVAC performance optimisation include:
Cooling and heating coil cleaning
Maintaining the cleanliness of heating and cooling coils in HVAC systems is essential to their efficient operation.
Significant cost savings can be made in this area.
Our HVAC services include auditing heat transfer capabilities for both cooling and heating coils, and complete coil cleaning services to ensure optimum heat transfer and air flow efficiencies are maintained.
HVAC filter management
HVAC filter management designed to optimise heating and cooling performance and energy efficiencies.
Typically this would involve an assessment of the required environmental conditions to understand desired outcomes, and then matching this to the most effective filter combinations for performance, efficiency and lifecycle cost.
Energy efficiency for boilers & steam generating processes
The safe, energy efficient operation of boilers and steam generating systems relies heavily on the effective treatment of the boiler water itself.
Poor management of internal heat transfer surfaces and boiler water quality and can seriously affect both boiler performance and asset integrity.
This can lead to increased costs, wasted energy and potentially result in serious damage to the boiler.
Our expert energy efficiency and boiler water treatment experts take a holistic approach to the management of both the boiler and wider steam system.
Our approach is designed optimise costs and operational efficiencies, maintain steam quality, achieve water and energy savings, and increase plant reliability and safety.
Energy efficiency for cooling towers & evaporative cooling systems
Cooling towers and evaporative cooling systems are used to provide cooling for chillers, air conditioning equipment, and many manufacturing and process applications.
They do this using a heat transfer or heat rejection process involving the evaporation of water to the atmosphere.
This evaporation process means they can consume significant amounts of water.
The energy efficient operation of cooling towers relies heavily on the effective treatment of the recirculating water used in the cooling tower system.
Poor water quality management can seriously affect cooling performance, water and energy efficiencies and asset integrity.
Water is lost from a cooling tower in a number of ways including:
Evaporation
Recirculating water evaporates from the cooling tower and is rejected to the atmosphere.
Blowdown
As water evaporates from the cooling system, dissolved solids begin to concentrate.
As concentrations increase these solids can cause scaling and corrosion problems.
Such concentrations are typically controlled by blowdown which involves draining water from the cooling system.
Blowdown should be carefully controlled to optimise water efficiencies.
Drift
Small volumes of water leave the cooling tower as a mist or as water droplets, and this is called drift.
The volumes of water lost as drift are typically small and can be controlled with baffles and drift eliminators fitted to the tower.
Our expert energy efficiency and cooling water treatment experts take a holistic approach to the management of cooling towers and evaporative cooling systems.
Our approach is designed optimise costs and heat transfer efficiencies, achieve water and energy savings, and maintain asset integrity.
