At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

Dryden Aqua ZPM: Flocculation Engineering and Mechanical Disinfection

The Dryden Aqua ZPM is a stainless steel static mixer designed to optimize water treatment by amplifying the Zeta potential. This device performs instantaneous reagent mixing and hydrodynamic cavitation to neutralize the charge of colloidal particles. Inaction in conventional filtration systems allows pathogens and microplastics to pass through the filter bed. The Dryden Aqua ZPM resolves this technical risk through mechanical flocculation and physical disinfection, guaranteeing biologically safe water with lower chemical usage.

Zeta Potential Optimization and Hydrodynamic Cavitation

The Dryden Aqua ZPM uses internal fins to generate high-energy turbulence. This physical process reduces the electrical charge of suspended particles, allowing flocculants to act with 100% efficiency before reaching the filter.

  • Cavitation Disinfection: The controlled pressure drop generates vacuum bubbles that collapse and destroy the cell membranes of bacteria and parasites.

  • Instant Reagent Mixing: Ensures a homogeneous distribution of coagulants and flocculants in the water flow, eliminating chemical waste.

  • Efficient Mechanical Flocculation: Groups fine particles and colloids into large-sized flocs that are easily retained by the AFM filter media.

  • Passive, Zero-Consumption Component: A static device made of stainless steel that requires no electrical supply or mechanical maintenance.

Chemical Robustness and Critical Engineering Standards

The fabrication of the Dryden Aqua ZPM in high-quality stainless steel ensures total resistance against corrosion and the attack of concentrated chemicals. Its design is intended for uninterrupted operation in the most demanding technical rooms.

  • AISI 316L Stainless Steel: Industrial-grade material that resists oxidation and guarantees the purity of the treated water.

  • Central Reagent Injection: Features injection ports that introduce the chemical into the core of the turbulence for immediate chemical reaction.

  • Integrated Grounding: Includes a grounding terminal to eliminate static electricity and protect the galvanic integrity of the piping network.

  • Quality Certification: Component designed according to European standards for IT/OT integration in high-level water management systems.

Technical Specifications

  • Fabrication Material: AISI 316L stainless steel.

  • Pressure Drop: Less than 0.1 bar (under nominal flow conditions).

  • Injection Ports: 1/2 inch connections for chemical dosing.

  • Hydraulic Connections: Flanges or threads depending on diameter (from DN40 to DN300).

  • Maximum Operating Pressure: 10 bar.

  • Functionality: Static mixing, cavitation, and mechanical flocculation.

  • Chemical Compatibility: Resistant to common flocculants, coagulants, and oxidants.

Compatibility and Application Limits

The Dryden Aqua ZPM must always be installed before filtration for flocculation, or after the filter to enhance disinfection. Its use is recommended in conjunction with AFM filter media to maximize transparency and biosecurity results. TECHNICAL RESTRICTION: Do not install the unit in pipe sections with extreme mechanical vibrations. Sizing must be adjusted to the water flow velocity to ensure cavitation; a velocity that is too low nullifies the mechanical disinfection effect.

Frequently Asked Questions

  • Where exactly should the Dryden Aqua ZPM be installed? To optimize filtration, install the Dryden Aqua ZPM between the pump and the filter. To enhance disinfection with chlorine or ozone, install a second unit after the filter to ensure a homogeneous and safe mixture.

  • Does the Dryden Aqua ZPM require any maintenance? No. As a static mixer with no moving parts, the Dryden Aqua ZPM does not suffer mechanical wear. It only requires an annual visual inspection to ensure that the chemical injection points are free of obstruction from scaling.

  • Is it necessary to connect the unit to a ground? Yes. Grounding is critical to neutralize the electrical potential generated by the water flow. This protects the installation against galvanic corrosion and improves the efficiency of mechanical particle flocculation.
