Osmosis System Platinum Line Plus by Aqua Medic

The Platinum Line Plus is a premium RO unit designed for users who need a large supply of very pure water — aquariums (both saltwater and freshwater), terrariums, or any application where purity, reliability and capacity count. The “24V” version refers to the updated model that operates at low voltage (24V), which adds a measure of safety and efficiency.

It includes a high-pressure pump (a booster / pump module) to drive the RO membrane, prefilter stages, and a flushing/valve mechanism to improve maintenance and performance.

Here are what make this system stand out:

• High output capacity: It can produce up to ≈ 400 litres per day of purified RO water under standard conditions.

• Very high salt /TDS removal efficiency: Up to 99% salt removal.

• Good pure-water vs waste-water ratio: Because of the included high-pressure pump and a flushing/valve system, the ratio of pure water to waste water can be as good as 1:1 in ideal conditions. This is much better than many basic RO systems that often have worse waste ratios.

• Modular, serviceable design: Comes with three large 10″ filter housings (pre-filters) for:

  1. A sediment / fine filter (to remove particulates)

  2. An activated carbon filter (to remove chlorine / organics)

  3. A demineralization resin cartridge (for polishing / ion-exchange)

• Automatic flushing / continuous monitoring: There is a flush-valve to help rinse the membrane, reducing fouling and scaling, which helps maintain high rejection and prolong membrane life. Also, there is a pressure gauge so you always know the operating pressure.

• Compact & rugged build: All components (prefilter housings, membrane module, pump) are mounted on a sturdy powder-coated (or anodized) bracket. The three 10″ filter housings allow standard filter cartridges.

• Resin volume: The demineralization resin polishing stage has a filling capacity of about 600 ml.

Technical  Specification 

• Nominal output: ~ 400 L/day (~105 US gallons/day) under good feedwater conditions.

• Salt removal / rejection rate: up to ~ 99% salt removal.

• Pure-to-waste water ratio: Up to 1:1 in optimal conditions thanks to the booster pump and flushing ability. In less ideal conditions might be worse.

• Prefilter housings: Three 10-inch filter housings: one for sediment / fine filter, one for combined carbon + sediment, one for the resin cartridge.

• Resin cartridge: ~ 600 ml for demineralization / polishing.

• Filter tubing size: ~ ¼ inch (≈ 6-7 mm) tubing for feed / product/waste lines.

• Dimensions: approximately 38 × 22 × 47 cm (length × width × height).

• Voltage / power version: 24 V version (newer update) for safety and possibly energy efficiency.

How It Works the Osmosis System Platinum Line Plus

1. Feed water enters (tap / source), ideally pre-filtered for large sediments etc.

2. It passes through the sediment / fine filter (removing particulates > ~5 µm).

3. It then goes through the carbon / activated charcoal prefilter stage to remove chlorine / organics etc. Chlorine can damage RO membranes, so this is very important.

4. Water is pressurized via the high-pressure pump, then forced through the RO membrane, which removes the majority of dissolved salts, organics, etc.

5. The flush / flushing valve allows periodic rinsing of the membrane to reduce scaling and fouling, helping maintain performance (reject rate, flow).

6. After the RO membrane, there is a polishing / ion exchange resin (demineralization resin) cartridge to remove remaining ions (like silicates, nitrates etc.), especially useful when very high purity is needed.

7. There is continuous monitoring (pressure gauge) to see operational pressure. When pressure drops, or water output drops, or TDS / conductivity of output water begins rising, those are indicators some component (prefilter, membrane, resin) needs attention or replacement.

These are the ideal applications or scenarios:

• Large aquariums / reef systems: Where frequent large water changes are needed and ultra-clean water is required (low salt, low contaminants).

• Marine aquarium setups particularly sensitive to silicates, nitrates, phosphates etc.

• Terrariums / spray / mist systems where water quality and purity matter.

• Any situation where reliability and low maintenance are valued, since this uses automatic flushing, easy filter changes, and robust components.

• Users who want high output so less waiting, or can feed multiple tanks or uses from one RO system.

Things to Watch 

No system is perfect; here are the caveats and what to watch out for:

• Real output depends on feedwater quality & pressure & temperature. If your feed water is cold, low pressure, or high in TDS/hardness, you may not reach “400 L/day”.

• Waste water / reject water is still present; 1:1 is best case; in less ideal conditions you may have more waste. If water conservation is important, that matters.

• Maintenance costs: Prefilters, membrane replacements, resin cartridge, etc. These all need periodic replacement; their lifespan depends heavily on water quality and usage.

• Space and installation: Though compact, you’ll need room for the unit, for hoses or plumbing, possibly mounting, and access for changing filters.

• Power consumption: The booster pump consumes more power than non-pump systems. May need appropriate electrical safety setup.

• Monitoring needed: You’ll need to keep an eye on system pressure, purity (often via TDS or conductivity), filter status, membrane condition.

Practical Tips for Getting Best Performance

• Use a pre-filter (sediment) stage ahead of this if your source water has a lot of particulates.

• Replace carbon prefilter regularly to avoid chlorine breakthrough which damages the RO membrane.

• Use the flushing valve regularly, especially if membrane sees heavy use or hard water.

• Keep an eye on output TDS / conductivity; when you see degradation, first check prefilters, then membrane, then resin cartridge.

• If using for sensitive marine aquarium, consider using the demineralization resin / polishing cartridge always (not just optional) to reduce tiny trace ions.

• Ensure the booster pump has correct supply (voltage, current) and that hoses/fittings are properly secured to avoid leaks.
