Dryden Aqua is a Scottish based Marine Biological company established in 1980 specializing in water quality and innovative treatment technology for a variety of industries including; drinking water, aquaculture, waste water treatment and swimming pools.

We are a manufacture R&D company, we identify issues or problems and then manufacture products or systems to solve the problem. One of our key products is AFM® (activated filter media) developed out of 30 years R&D. AFM® replaces sand in sand filters and doubles the performance of the filters. Given that sand is used in over 99 % of the worlds filtration systems, this is considered disruptive technology.

Currently we are conducting research for the European Commission under FP7 with a European consortium and Indian Government (www.eco-idia.eu) to solve the problem of arsenic in drinking water. This is an issue that affects over 1/4 of Billion people in India. Above all, at Dryden Aqua we are an ethical company, winners of Vibes circular economy for sustainability, with a focus on protecting our aquatic environment, elimination of toxic chemicals in drinking water and trying to make the world a better place for everyone.

Dr Dryden started his company, Dryden Aqua, in 1980. Making use of his PhD, he has established this marine biology company which focuses on manufacturing specialist products to improve, treat and protect all aquatic environments. The company's core product is AFM which replaces sand in water filters which are used across many industries to treat drinking and waste water effluents. AFM provides a sustainable option for industry, allowing them to meet their CSR commitments and take real action against the environmental degradation which can result from sand mining. AFM is now recognised as the most effective water filtration media in Europe. It can remove parasites and bacteria, and the molecules of some of the most toxic priority substances and heavy metals such as arsenic and chromium.

AFM, is manufactured in a 'cradle to cradle' approach from green container glass. The new plant can recycle the equivalent of 25% of all the green glass bottles currently available in Scotland - some 40,000 tonnes /year.

A second facility is now in planning which will be x 3 times the size of the current plant, and this could use 100% of all the green container glass In Scotland and will give Scotland a Zero Waste designation.

At Dryden Aqua 90% of AFM is exported to Europe, Middle East and Asia, manufacturing & Research in Edinburgh, Distribution and PR in Switzerland.

Sand is used to treat most of the drinking water in all countries, however there are still huge problems, with pathogen, parasites and toxic chemicals. Simply by changing the sand to AFM the performance of the filters will double. AFM will therefore eliminate parasitic infections which account for 50% of all water borne disease. AFM will also remove copepods which are the main vector for Cholera. We are currently working on a project www.Eco-India.eu and believe we have a solution for arsenic in Drinking water.

1/4 billion people in India suffer from arsenic poisoning and perhaps 1 billion around the world are exposed to high concentrations. We can solve this problem and are proving it on the ground in a remote village in India
