Dupla Dupla RO600

Product Description

Dupla RO600

» The reverse osmosis system removes contaminants and hardness-causing substances from tap water, thereby optimally treating it. Reverse osmosis water is used as the source water for saltwater and freshwater aquariums and provides the perfect, uncontaminated foundation.

• Creates optimal source water for saltwater and freshwater aquariums

• Contaminants (e.g., silicate, nitrate) and hardness-causing substances are physically removed from the water.

• The downstream ultrapure water filter removes even the smallest residues

• Concentrate-to-permeate ratio: 1 : 1 (depending on the quality of the source water)

• The average retention rate of the membrane is 90–98%

• Capacity: approx. 600 L/day

• Concentrate-to-permeate ratio: 1 : 1

Dupla RO600 Reverse Osmosis System

Reverse osmosis systems produce optimal source water for marine and freshwater aquariums. Often, many water-related problems can only be solved by using reverse osmosis water. Reverse osmosis systems operate on the principle of physical filtration. Unlike ion exchangers, for example, which replace hardness-forming ions (e.g., calcium) with other, non-hardness-forming ions (e.g., sodium), a reverse osmosis system physically removes contaminants (e.g., silicate, nitrate) and hardness-forming substances are physically removed from the water. The water flows through a semipermeable membrane in the reverse osmosis system under the pressure (2–6 bar max.) typically found in household water lines. The substances dissolved in the water (contaminants, salts, or hardness-forming substances) cannot pass through the membrane’s fine lattice structure and remain in the wastewater. This wastewater is discharged as concentrate and can be safely used for cleaning, watering plants, or general household purposes. The downstream ultrapure water filter removes even the smallest residues from the permeate (the usable water from a reverse osmosis system) and indicates the exhaustion status of the exchanger (Duresin RI) by changing color from blue to green. The PWT (Pure Water Tester) can be used at any time to easily check the water quality of the permeate (usable water).

Technical Specifications

• Capacity: approx. 600 l/day, depending on the quality and pressure of the incoming water

• Average capacity: 500–650 L/day at 8–15°C and 3–6 bar pressure

• Concentrate-to-permeate ratio: 1 : 1 (depending on the quality of the feed water)

• The average membrane rejection rate is 90–98%

• Aluminum: 97–98%

• Cadmium 95–98%

• Bacteria 99%

• Nitrates: max. 90%
