In the UK in recent decades with the closing of active mining in parts of the coalfields, mine water discharges have emerged as the water table recovers from artificial control during mining operations.

The recovery of the water table creates the potential risk of pollution of the water environment from either flooding of former workings after extraction had ceased, or discharge of untreated waters after flooding of the mines is complete.

The European Water Framework Directive requires all bodies of water in the EU to be of ‘good ecological quality’ within certain timescales. Water impacted by mine water do not always meet this requirement and therefore the objective is to treat those discharges which lead to non-compliance.

SUEZ Advanced Solutions provide mining companies with effective technological solutions related to the complete water cycle and provide customers with bespoke solutions to meet their individual needs.

The global Aqualogy group has a high level of experience in mining projects (metal, energy, natural stone and precious metal) specifically in Latin America and Spain, where we have numerous references in all the services we offer.

Water reuse for Cosentino, Spain. 2013

Water reuse for Cosentino, Spain. 2013

Design, construction, commissioning and monitoring of process water, waste treatment and reclamation plants to supply the process with high-quality water.

These plants combine filtration, membrane and sulphate removal technologies to ensure high performance in terms of clean water production and compliance with quality standards. The project has two treatment lines: the first is for the production of 300 m³/day of technological water, with a rejection flow of less than 6% of the input water; and the second is for 100 m³/day of rejected water, which is reused in the process.

Treatment of acid mine drainage. GLENCORE, Peru. 2014

Treatment of acid mine drainage. GLENCORE, Peru. 2014

Design and construction of three treatment plants for effluents from copper and zinc mines. The plants have been designed to neutralise acid mine drainage at three different points, with flows of 14,000 m³/day, 6,000 m³/day and 9,000 m³/day.

All the plants will ensure the correct return of effluent to the environment, with the last one also being capable of reusing water in the metallurgic process.

O&M of an osmosis plant for mining process water. Sierra Gorda Sociedad Contractual Minera, Chile. 2014

O&M of an osmosis plant for mining process water. Sierra Gorda Sociedad Contractual Minera, Chile. 2014

The services cover the supply, operation and maintenance of the reverse osmosis plant, designed to produce 370 m³/h of permeated water, mostly as process water, and 35 m³/h of drinking water. The process water is used in the metallurgical plant for the recovery of copper and molybdenum.

The contract is based on compliance with a series of efficiency objectives, which are continuously measured through the application of KPIs. They are defined as bonus or malus depending on the level of compliance, establishing a partnership relationship with the customer.


Historically sludge and biomass were seen as waste to be disposed of, with uncertainty around land application, they are now increasingly considered valuable resources for content and energy potential, now more relevant due to significant subsidies for renewable energy through ROC, FIT and RHI schemes.

Aqualogy have extensive experience in the operations of wastewater, grey water, effluent and sludge treatment, and have specialised solutions designed to:

  • Produce more renewable energy
  • Increase efficiency, in particular in terms of energy use
  • Reduce the quantity of end-of-line waste to dispose of

Our sludge drying systems are designed to provide more opportunities for end management, including energy recovery and also reuse. The systems are also intrinsically safe, enabling the use of energy recovered from the various processes.


Water, wastewater and effluent treatment processes are key in order to meet the necessary legislations and also reduce total operating costs. Aqualogy are focussed on the development of technologies to optimise these process.

Our team of experts work with customers to provide bespoke tailored solutions to reduce the running costs of their assets, increase operational efficiency and improve environmental performance.

Our services include:

  • Analysis of existing processes and water usage
  • Identifying methods to reduce costs
  • Bespoke tailored solutions for increased efficiency
  • Process optimisation using integrated solutions
  • Improving environmental performance
  • Compliance with environmental legislation


Aqualogy provide a full range of environmental and analytical services covering all water management needs. Operating throughout the UK, we are specialists in:

  • Analytical control of water quality
  • Quality management of process waters and discharges
  • Environmental consultancy and monitoring
  • Environmental management systems


Water scarcity and the need for proper management pose serious challenges for water intensive industries.

Treating wastewater streams to allow reuse in industrial processes creates a sustainable and more efficient process management method. With the aim of optimising water consumption, Aqualogy conducts studies and undertakes projects to optimise the various water flows within the manufacturing process.

With a comprehensive understanding of the uses of water in manufacturing plants and the needs of production processes, we can make proposals and deliver measures to improve, optimise and reduce the consumption of water and associated scopes (energy, chemical reagents and sludge management).
We offer a wide range of applications that treat and reuse process water, all while maximizing treatment capacity, reducing VOC emissions, improving safety and reducing costs.


The water footprint (WF) is an essential indicator to calculate sustainability in the use of natural resources by humans.

Many organisations are conscious of their carbon footprint and are actively trying to reduce it. Although saving energy is an obvious strategy, saving water is also very effective due to the energy used in water treatment processes. Therefore Aqualogy provide both water and carbon efficiency audits.

Water efficiency audits provide bespoke plans for water savings and to minimise costs, without losing process efficiency and effectiveness.

Analysis of an organisation’s carbon footprint covers everything from the study and development of a procedure for establishing greenhouse gas emissions, to the planning and management to reduce these. It includes all the activities and infrastructures associated with the complete water cycle.




ECT will result in very high COD reductions. Heavy metal pollutant removal reduces trade effluent charges. Waste streams can be treated where conventional treatment will not meet regulatory compliance. Design and build solutions and the integration of complementary technologies can result in water re-use.
