Advanced Enviromental Technologies Ltd. is committed to environmental protection and recycling

Our team includes time served and qualified geologists, process designers and mechanical engineers with decades of experience in mining, quarrying, dredging operations and the treatment of problem areas associated with wet waste. AETs' cleantechnology and techniques are designed to be flexible.

We have pioneered the concept of mobile treatment units, allowing our solutions to be literally driven onto a problem site. This not only greatly reduces transportation costs but also dramatically reduces the thresholds at which our solutions are viable when compared to fixed location sites.

We also work closely with a variety of chartered engineers, to ensure our treatments are properly assessed and audited. We have experience in gaining regulatory consent from Environment Agency (EA), DEFRA (Department of Environment, Food and Rural Affairs) and English Nature directives in the UK.

Our Solutions

Geo-technology has been developed over the past thirty years and have proven record of excellence throughout the civil engineering field. Furthermore, in addition to an extensive product range, geo-technology offers systems solutions in the form of customised proposals aimed at solving problems relating to road and railway construction, hydraulic structures and tunnels, reinforced earthworks, and a variety of other applications including Geo-technology for coastal protection and embankment reinforcement. In fact, as a consequence of close co-operation with geo-technical experts, the company is able to respond in a highly professional manner to any of the special demands posed by advanced civil and geo-technical engineering.

As a result of ongoing, technological development, product innovations and in-house software for geotextile design thetechnology has created the prerequisites for a leading market position. Our engineers dispose over a vast range of expertise in geotechnology, application, synthetics and textile fields, which enables them to establish new benchmarks with regard to the design, production and marketing of geo-synthetics. Moreover, a global sales and distribution network, staffed by competent technical and commercial specialists, ensures that we are always close at hand when our customers need us.

Geo Technology

Geotechnology was developed over 40 years ago to protect the environment, stop storm damage, build custom structures and even build islands. Geo-technology is made out of woven high strength textiles. They are designed to stand the test of time and water with a unique fabric structure that is tough but flexible. Regular tests are carried out, using a Tensile Testing machine to test strengths and strains.  

Geo-technology can be used for:

  • The containment of contaminated dredgings
  • Wetland creations
  • Island creations
  • Breakwaters
  • Dam construction
  • Marina construction
  • Reclamation bunds
  • Shoreline protection
  • Beach Restoration
  • Be de-watered



Sulphate Technology

Sulphates traditionally can only be precipitated to around 2,000mg/l or higher by precipitation with calcium. Although the theoretical level is 1,500mg/l this can not be achieved due to interferences.

What can be done to achieve consent levels?

  • Precipitation with barium – this is costly and not widely done due to the fact barium chloride is highly toxic.
  • Membrane filtration – easily fouled/scaled by effluent and what do you do with concentrate reject.
  • Ion exchange – easily fouled but often used with large flows e.g. mine water
  • Heating – calcium sulphate is less soluble at higher temperatures. Not used due to the fact it is a batch process and energy costs.
  • Biological – takes a long time so plant is large and capital intensive.
  • Precipitation with calcium aluminate – needs two stage precipitation and settlement. The reaction takes time and is not cost effective as it requires double amount of equipment. Also system suffers from limescale build up.
