What Dryden Aqua does
Dryden Aqua is a privately held aquatic environmental water-treatment company founded by marine biologist Dr. Howard Dryden and headquartered in Bonnyrigg, Scotland (UK), with European sales operations based in Büsserach, Switzerland. Its flagship offering is AFM® (Activated Filter Media), a proprietary glass-based filter media produced through a patented three-step chemical and thermal activation process that yields a bio-resistant, high-surface-area substrate capable of 1-micron mechanical filtration, 10+ year operational lifespan, and 50%+ backwash-water reduction compared with silica sand. The company manufactures AFM® in two solar-powered, zero-waste glass-processing facilities in Switzerland and Scotland from 100% recycled post-consumer green and brown glass, and has invested €1.5M in colour-sorting lines to ensure feedstock purity.
The product portfolio spans the full water-treatment stack: AFM® media, chemical consumables (APF® coagulant/flocculant, ACO® chlorine stabiliser, NoPhos, Advanox™ advanced oxidation), dosing and mixing equipment (Stenner pumps, Besgo valves, ZPM®, FlowVis®, DA-GEN® hydrolyser, air diffusers), and the SPACE® IoT automation platform with machine-learning predictive maintenance. These components are sold both as individual items and bundled into the DAISY®/DAISY+ integrated pool systems. Customers span four primary verticals — municipal and industrial water treatment, commercial and residential swimming pools, aquaculture (RAS, hatcheries, shrimp), and aquaria/zoo life support — with named references including Cape Town SWRO desalination, Ford Cars, Nucor Steel, VIET-UC (the world's largest shrimp hatchery), Oceanario de Lisboa, and Resorts World Las Vegas.
Dryden Aqua generates revenue through hardware sales of filtration media (with extended multi-year replacement cycles), recurring consumable chemistry tied to installed base, and capital equipment plus integrated systems. Distribution is channel-led via four regional distributor portals (Americas, Europe, APAC, MEA), supported by wholly-owned subsidiaries in Germany (Dryden Aqua Deutschland GmbH, Weimar), the United States (Dryden Aqua LLC, Dallas), and China (Dryden Aqua China, Zhongshan), with technical training delivered through the Dryden Pool Academy in five languages and the company's four YouTube channels.

Revenue model
- AFM® Activated Filter Media: Sale of AFM® filter media to municipal water treatment plants, industrial facilities, swimming pool installers, and aquaculture operations. AFM® is sold as a direct replacement for silica sand in new installations and retrofits. Revenue is recurring as media has a 10+ year lifespan but requires periodic replacement in high-use applications.
- Water Treatment Chemicals & Consumables: Sale of APF®, ACO®, NoPhos, and Advanox™ chemical products for swimming pools and water treatment. These are recurring consumable products dosed continuously or periodically, providing repeat purchase revenue from installed customer base.
- Equipment & Automation Systems: Sale of Besgo valves, Stenner pumps, FlowVis® flowmeters, ZPM® static mixers, DA-GEN® hydrolysis units, and SPACE® automation controllers. Equipment may be sold standalone or as integrated DAISY® or DAISY+ systems. Pre-assembled control panels (SPACE PRO) are offered for quick installation.

Dryden Aqua product offering
Product offeringCore offering
Dryden Aqua manufactures and sells AFM® (Activated Filter Media), a bio-resistant glass-based filtration media produced from 100% recycled glass through a proprietary three-step chemical and thermal activation process. The company complements AFM® with a portfolio of water treatment chemicals (APF®, ACO®, NoPhos, Advanox™), equipment (valves, pumps, flowmeters, mixers, hydrolyser), and integrated systems (DAISY®, DA-GEN®, SPACE® automation) sold to municipal water utilities, industrial facilities, aquaculture operations, aquaria/zoos, and swimming pool installers/distributors globally.
Product overview
Dryden Aqua offers a comprehensive water treatment portfolio combining filtration media, chemical treatments, equipment, and intelligent automation systems. The core product is AFM® activated filter media, which serves as the foundation for various treatment solutions. This is supplemented by chemical products (APF® coagulant/flocculant, ACO® chlorine stabilizer, NoPhos phosphate remover, Advanox advanced oxidation) and equipment (Air Diffusers, Besgo Valves, Stenner Pumps, FlowVis flowmeters, ZPM static mixers, DA-GEN hydrolyser). These integrate into higher-level solutions including DAISY® (an integrated pool treatment system combining AFM®, APF®, NoPhos, and ACO®) and SPACE® (an intelligent pool automation platform with machine learning). DAISY+ combines DAISY® with DA-GEN® for drinking-water quality pool water. The company serves swimming pools, municipal/industrial water treatment, aquaculture, and aquaria/zoo markets.

Products and services
- AFM® Activated Filter Media Activated bio-resistant filter media manufactured from 100% recycled glass, providing superior filtration performance down to 1 micron and preventing bacterial growth and biofilm formation. Available in AFM® s (standard hydrophilic) and AFM® ng (next generation hydrophobic) variants for municipal, industrial, pool, aquarium, and aquaculture water treatment applications.
- APF® All Poly Floc Multi-spectrum coagulant and flocculant containing a precise combination of 5 active components for wide-spectrum coagulation and flocculation. When used with AFM®, removes particles down to 0.1 micron, reduces chlorine consumption by up to 80%, and prevents algae growth at source through NoPhos phosphate removal.
- ACO® Active Catalytic Oxidation Liquid UV-protectant that filters UV light to prevent photoreduction of chlorine by sunlight in outdoor pools. Reduces chlorine consumption by 50% compared to non-stabilised pools without reducing chlorine effectiveness and without building up over time (unlike cyanuric acid).
- NoPhos Natural phosphate remover that binds phosphates into insoluble compounds to prevent algae and bacterial growth at source. Safe for all aquatic life and used in aquariums, coral systems, and swimming pools.
- Dryden Air Diffusers High-efficiency fine bubble diffusers for water aeration, oxidation, and mixing. Self-ballasting design with typical lifespan of over 10 years in chemically aggressive environments; outperform German-made disc diffusers by 24% in oxygen transfer rate.
- Besgo Valves Swiss-made pneumatic automatic 5-way backwash and 3-way selector valves for automating sand/AFM® filter systems in water treatment, aquarium, aquaculture, and swimming pool applications. Available from d.50mm to d.140mm; TÜV Rheinland certified.
- Stenner Pumps USA-made premium quality peristaltic dosing pumps (Floc-Dos, Econ VS, Classic Series, S Series) for accurate automatic dosing of APF®, ACO®, and other chemicals in DAISY® systems. Self-priming with tool-free tube replacement.
- FlowVis® Flowmeter Patented 2-in-1 flowmeter with integrated check valve functionality (in d50mm and d63mm models) for flows from 2.4–420 m³/h. ≥98% verified accuracy, maintains accuracy with air in the system, and installs without requiring straight pipe runs. NSF 50 Level 1 certified.
- ZPM Zeta Potential Mixer Static mixer with proprietary fin geometry that creates water cavitation at 0.5 mBar differential pressure, enabling amplification of coagulation/flocculation reactions, zeta potential neutralisation for particle coalescence, and mechanical pathogen destruction through cavitation. Manufactured in stainless steel or titanium for marine applications.
- DAISY® Integrated System Integrated biological and ecological water treatment solution for swimming pools that combines AFM® filtration, APF® coagulation/flocculation, NoPhos phosphate removal, and ACO® oxidation. Reduces chlorine use by 50–80% and backwash water by up to 80% versus traditional sand filter systems.
- DA-GEN® Hydrolyser Hydrolyser using advanced oxidation technology to generate free radicals (OH• and O•) at very low salt levels (1g/L NaCl or MgCl2). When combined with DAISY®, produces pool water of drinking water quality — crystal clear with no chlorine smell. Includes pool controller with WiFi module and dedicated app.
Quantifiable outcome
- AFM® s Grade 0 removes 98% of particles >1μm; AFM® ng Grade 1 removes 95% of particles >1μm (vs sand at 95% >20μm) — independently verified by IFTS
