About Dryden Aqua

Dryden Aqua is a Scottish based Marine Biological company formed in 1980 specializing in water quality and innovative water treatment technology. We have a strong research and development background and conduct research for the water industries (Eco-India FP7 project), European Commission and UK Government

As marine biologists our focus has been with the aquaculture and environmental business sectors. An understanding of the biological as well as the physio-chemical reactions has permitted Dryden Aqua to develop a unique range of products and technology relating to; media bed filtration, coagulation, nano-technology and sono-chemistry. A new hypothesis has also been developed that relates Marine Biodiversity to climate change which has the potential to reverse the condition.

The web site is in 9 sections

1. AFM Active filter media

Active filter media was developed by Dryden Aqua to replace sand in all types of sand filter, from Drinking water to waste water treatment. AFM will improve the performance of most sand filters by around 50% and provide up to 30% operational cost savings in terms of water, energy and chemical consumption.

2. Aeration & Oxygenation systems

Dryden Aqua manufacture a unique range of fine bubble air diffusers and ceramic oxygen diffusers. Our air diffusers are used in large scale aeration of lakes and reservoirs to fish farms and agricultural farms as part of a biological grey water SBR recycling systems. Our diffuser are the leading product used for landfill leachate treatment in the UK.

3. Aquaculture & public aquaria

Dryden Aqua are marine biologists specializing on water treatment and recirculation technology for intensive closed system aquaculture and some of the larges public marine aquaria in the world.

4. Chemical products

As marine biologists we try to avoid chemicals, however many of the products being provided to our industry are not optimized for the application or have too high a concentration of chemical by-products. Dryden Aqua were therefore required to develop and manufacture a new range of high purity products such as APF active polyfloc, ACO active chemical oxidation and DryOx.

5. Products & equipment

Dryden Aqua manufacture many products that can be used in a wide range of industries, such as our vacuum degassing column. DIN standard pressure filtration systems, ZPM static mixers. In addition to the products manufactured by Dryden Aqua we have on display products manufactured by our associate companies.

6. Instrumentation for water quality monitoring

Water quality is central to all systems, we do not think it is good enough to be acceptable, we want our clients to have the best possible water quality at a fair price. Oxygen monitoring is one of the most important parameters and Dryden Aqua are the largest manufacturer of galvanic oxygen probes in the UK. We are also the leading oxygen probe manufacture for the world aquaculture industry.

7. Ozone

Ozone ins a very useful water treatment process for many applications, the web site contains a range of ozone generators for water and air treatment as well as venturi injection systems.

8. Swimming pool industry

Dryden Aqua integrated water treatment systems and AFM are now installed in over 50,000 pool systems in Europe. We have developed technology that can recycle 100% of the water and comply with the highest standards of water and air quality. Our systems provide the best and safest conditions for the public as well as pool staff or the private user. Our systems may be a bit more expensive than other systems, however in all cases examined the Dryden Aqua Integrated system is at least 30% more efficient and can achieve a return in capital out of revenue in under 18 months.

9. Water treatment, drinking water, waste and industrial water

WHO (World Health Organization), report 6% of all disease in Europe is from drinking water, of these infections 50% is due to Cryptosporidiosis. More than 90% of all drinking water in Europe is filtered by sand filter. All sand filters will suffer from transient worm-hole channeling. Dynamic bio-instability of sand filters leads to coagulants such as aluminium being discharged in to the water along with prions, viri, bacteria, parasites, endotoxins and exotoxins.

Ammonium is also added to water to try and prevent THM`s (mainly chloroform) forming in the water, however ammonium promotes autotrophic bacteria growth and forms more DBP`s. A chemical or engineering solution is attempted to try and solve a biological problem. There are much more efficient, safer and cost effective biological solutions. Dryden Aqua technology has the potential to eliminate the above problems and reduce the operating cost of treating drinking water by up to 30%.

Wastewater treatment website .....remove list 1 chemicals, 1/10 the cost of the alternatives

The principal source of environmental water pollution is effluent for sewage works. The Royal Commission Standards were set in the UK over 100 years ago, however very few treatment works are actually in compliance with a 100 year old standard. Dryden Aqua tertiary treatment AFM filtration media can treat sewage water to a standard approaching the quality of drinking water at about 1/10th the cost of any alternative technology.

Environmental pollution from sewage works contaminates the environment and our drinking water sources. Also list 1 chemicals discharged in suspended solids is responsible for disease and cancer. Indeed we now believe that List 1 chemicals discharged from sewage works may be responsible, or at least partially responsible for Climate change. Dryden Aqua were the first to identify the link between and we offer a solution.
