AQVA AHTI L reverse osmosis system for point of entry purification

AQVA AHTI L Reverse Osmosis System for Well or Lake Water

The AQVA AHTI reverse osmosis system is the most effective solution for purifying drinking and household water from well or lake sources, producing up to 300 liters of clean drinking water per hour.

Delivery/Pickup: Available within 1–3 business days from order.

Order Options: Online store, email, or phone.

Easy to Install and Use:

This comprehensive system includes all necessary components, hoses, and fittings. It comes with a distribution pump, post-filters, and shut-off valves for water delivery from the tank to consumption points. Note that installation pipework for these components is not included, as it depends on the property’s plumbing system.

Designed to meet high water consumption needs, the AQVA AHTI is easy to use and maintain, even for seasonal cottage use. Filter replacements and maintenance are user-friendly and can be performed without professional assistance.

The system removes challenging contaminants such as uranium, arsenic, blue-green algae (99.9%), fluoride, and chloride, delivering crystal-clear, pure water. Water quality, including sediment and humus levels, may affect filter lifespan, but pre-filters are typically replaced annually, while reverse osmosis membranes can last several years.

Key Features:

• Made in Finland: Awarded the Key Flag symbol for Finnish manufacturing

• Produces up to 300 liters per hour at 6 bar feed pressure and 7°C water temperature (see detailed flow rate tables in the installation manual)

• Includes a 185-liter storage tank with an automatic float valve to maintain water levels, ensuring uninterrupted supply during peak usage

• Equipped with indicator lights, a pressure gauge, and water flow meters for monitoring system performance

• Reliable and user-friendly design with minimal maintenance

• Suitable for wells with moderately elevated salt (chloride) levels; consult with the seller for specifics

• Removes 85–99.9999% of common water contaminants, including:

  • Bacteria, viruses, cysts, yeasts, molds

  • Manganese, sulfur, hydrogen sulfide

  • Iron, uranium, humus (COD, KMnO4, permanganate)

  • Fluoride, chloride (approx. 85% removal)

  • Taste and odor impurities

  • Pipe-related contaminants, limescale

  • Hormones, antibiotics, pharmaceutical residues

  • Pollutants, color, agricultural and industrial residues

• Softens water for improved quality

System Components:

• AQVA AHTI reverse osmosis unit (product code: AQRO-AH)

• Reverse osmosis membrane housings and membranes (product code: AQ062)

• XL-sized pre-filtration package for solids, odors, and polyphosphate to extend membrane lifespan (anti-scalant type)

• 185-liter water tank with necessary fittings, connectors, and automatic float valve

• 1-micron breather filter for the water tank (product code: AQMF1-M)

• Near-silent Grundfos Scala1 distribution pump for delivering water from the tank to consumption points

• Post-filtration in AQVA L-sized housing (product code: AQUF01-L) to ensure hygienic water quality from the tank

• Neutralization filter package to adjust pH to optimal levels, containing natural calcium (product code: AQPH-XL)

• Connectors for linking the reverse osmosis unit to pre-filters and the water tank

Filter Replacement:

• Every 2 Years (or as needed):

  • 2 reverse osmosis membranes: AQ062 (may last longer depending on usage)

  • Post-filter: AQUF01-L (replace if clogged)

  • Remineralization filter: AQPH-XL

• Annually:

  • Pre-filter (activated carbon for solids and odors): AQCB-XL (may clog faster depending on sediment or algae levels)

  • Polyphosphate pre-filter: AQPF-XL

Typical Operating Costs:

For an annual water usage of approximately 100,000 liters (e.g., seawater in an outer archipelago with typical humus levels of COD 10 mg/L), average operating costs range from €200–400. Costs vary due to seasonal fluctuations in well water quality, influenced by snowmelt, rainfall, groundwater levels, or flow direction changes. Exact costs become clearer after the first usage seasons.

Technical Specifications:

• Water production: Approximately 312 liters per hour at 6 bar and 7°C (varies with water quality)

• Feed pressure: 2–6 bar

• Tank capacity: 185 liters (supports up to 500 liters/hour during peak usage)

• Pre-filtration: XL-sized dual-stage filtration

• Connection: Standard fittings for easy integration

Winter Storage:

Winter storage is straightforward using the included valves and shut-offs, as detailed in the installation and operation manual. When restarting in spring, perform an extended flush as per the manual, after which the water is ready for normal use.

Installation and Operation:
