The Parker Village Marine Tec. Remineralizer ensures safe, balanced water quality by gradually dissolving calcite into product water. This process raises the pH to near-neutral levels and adds mineral hardness, protecting metal pipes and fixtures from corrosion caused by low pH water.
Built for durability, the unit features a spun-wound fiberglass composite tank with a polyethylene liner, PVC schedule 80 piping connections, and a carbon steel base.
Important Maintenance Note:
Calcite media is consumed over time and must be replenished periodically. The unit comes with an initial fill of calcite media.
The Remineralizer improves water quality by adding a controlled amount of hardness and adjusting the pH toward neutral. It is typically installed downstream of a reverse osmosis (RO) system, before the fresh water storage tanks, ensuring optimal water balance without the need for additional pumping.
Function and Operation
The Remineralizer slowly dissolves calcite media into the product water, raising hardness and stabilizing the pH near neutral. This process is self-limiting, meaning:
Neutralizing reduces water “aggressiveness,” helping to protect metal pipes, fixtures, and system components from corrosion and wear.
By restoring buffer capacity, the Remineralizer ensures your fresh water is safer for your system and longer-lasting.

Below we have gathered a few of the benefits of a Parker Water Purification Watermaker.
Less weight, lower fuel costs, higher speeds:
Sailing with a full water tank, or an additional 1,700 pounds, leads to squandered fuel, reduced speeds, and abbreviated voyages. With this watermaker, you can cruise swifter and longer while generating fresh water right onboard. Our systems not only save boaters time and money but also optimize yacht performance.
Cruise without limits or boundaries:
Having this watermaker onboard means you can bypass scheduling your boating ventures around marina stops. Cruise directly to your destination or venture to boundless distances without the necessity of replenishing fresh water supplies.
Fresh water wash downs:
Using Water Purification water for wash downs proves exceptionally efficient in safeguarding your yacht's exterior, potentially enhancing its overall value. Parker Water Purification water functions like a sponge, adeptly absorbing and rinsing away all undesirable sea salt and minerals, leaving surfaces spotlessly clean and free of water spots.
Convenient for every boating activity:
Regardless of whether you utilize it for drinking, showering, or cleaning your yacht, having a Water Purification watermaker offers endless opportunities to save money and enjoy more leisure time. With such advantages, how can any boater justify not owning this Water Purification watermaker?
The Reverse Osmosis(RO) system needs installation in a dry, sheltered area shielded from direct weather exposure. Adequate drainage should be ensured beneath the RO unit to facilitate water runoff during maintenance or repairs.
The theory in short:
Let’s take a deep dive into the theory.
Osmosis, a natural phenomenon, occurs when a semi-permeable membrane separates a pure solution from a concentrated one (where a semi-permeable membrane selectively allows passage of substances). Each liquid carries an inherent potential closely tied to the nature and quantity of solids dissolved within it. This potential, termed osmotic pressure, rises with the relative concentration of a solution. Consequently, a concentrated solution exhibits a higher osmotic pressure compared to a pure solution.
In a desalination setup, the less concentrated solution balances the concentrations of both solutions by moving across the membrane. Once adequate pure solution migrates across the membrane to equalize the inherent potential difference, the flow of purer solution ceases.
However, if pressure on the concentrated solution exceeds the osmotic pressure, fluid flow reverses. This phenomenon, known as Reverse Osmosis, is achieved by artificially pressurizing the more concentrated solution using a high-pressure pump. In such a system, the concentrated solution (commonly called feedwater) becomes even more concentrated as pure water moves across the membrane to the permeate side.
Disregarding the impact of feedwater temperature and salinity, the operating pressure typically required to produce significant quantities of pure water is at least double the osmotic pressure of the membrane utilized.
Seawater encompasses various solids dissolved within it. The predominant component is typically ordinary table salt, sodium chloride. Additionally, other minerals found in solution often comprise diverse compounds of calcium and sulfate. The collective sum of these dissolved solids in a given water sample is termed Total Dissolved Solids or TDS. Seawater typically registers between 32,000 to 35,000 ppm (parts per million) TDS on average, although deviations of around 5000 ppm are commonplace across different regions globally. The primary objective of any desalination process is a notable reduction in the concentration of dissolved solids in water.
It's important to acknowledge that no system can entirely eliminate all dissolved solids from seawater. Instead, the system is engineered to reject approximately 99% of the TDS, allowing only 1% of the 35,000 ppm TDS in seawater to permeate into the product water. This results in water containing less than 500 ppm, the recommended TDS level for drinking water. A system configured in this manner is described as having a salt passage percentage of 1% or a salt rejection rate of 99%.
The purified and strained raw water, now termed feedwater, enters the inlet of the high-pressure pump. This pump elevates the feedwater pressure to 56-65 BAR (800 - 950 psi), the standard pressure necessary for optimal system recovery. Subsequently, the pressurized feedwater is directed into the membrane pressure vessels, forming an array. This array comprises fiberglass pressure vessels, each housing RO membrane elements.
Within the membrane elements, reverse osmosis occurs as the pressurized feedwater flows. The feedwater is bifurcated into two streams: the high purity product stream (referred to as the product) and the increasingly concentrated reject stream (referred to as the reject).
The table below demonstrates how alterations in temperature, salinity, and pressure impact both the quality and quantity of permeate generated by the RO system.
Should the salt concentration in the feedwater decrease, it's advisable to limit the increase in product water flow rate to no more than 20% above the rated flow. To maintain the rated flow in applications with brackish water or freshwater, adjustments to the Membrane Reject pressure may be necessary.
In scenarios where the feedwater salinity drops below the nominal level (e.g., near river mouths or in estuaries), the RO system can be fine-tuned to uphold a consistent permeate output. This adjustment can be achieved by manually controlling system pressure using the back-pressure regulator valve positioned in the system brine piping. To ensure prolonged pump life and minimal membrane fouling, Parker suggests not exceeding 9 psi, except in cases of extremely low temperature feed water.
BE AWARE that operating the unit at over 120% of its rated capacity in low salinity water can cause membrane damage.
Below we answer the most common questions from our customers, however, we encourage you to contact us if you need any help.
Absolutely. Brackish water poses no threat to the R.O. membrane or system. The Ultra Whisper automatically adapts its pressure to brackish water sources, ensuring optimal water production. Similarly, the Aqua Whisper's pressure can be manually regulated for normal operation with brackish water, delivering high-quality, potable water.
Potable water is necessary to "flush" or "store" the system, a process automated by the optional Fresh Water Flush feature, safeguarding both the R.O. membrane and system.
Indeed, once the Oil Water Separator is installed, it effectively extracts oil from the feed water, while the Ultra Violet Sterilizer ensures the sterilization of the product water.
Almost immediately, as it possible only a few moments after start up.
Absolutely, it's delightful, mineral-low, softened, refreshing, oxygenated, incredibly flavorful, pleasant, and ensures spotless dishes and washdowns!
No. Battery water necessitates distilled (0 PPM) water. Reverse Osmosis product water does contain minimal mineral content, suitable for drinking and washdowns but unsuitable for batteries.
No. We offer 12 & 24 VDC systems, along with AC systems that necessitate a generator.
Anywhere is suitable. While the engine room is commonly chosen, other viable locations include lazarettes, closets, under settees, or any available space.
From ½” to 1” depending on
the system.
Yes, the system can be positioned above water level, but it's essential for the Booster Pump (provided with the system) to be installed below the waterline.
Setting up the essential thru-hull fittings and electrical connections should be conducted by skilled and seasoned technicians. However, installing the system itself demands only fundamental mechanical proficiency and can be carried out by the user. Our thorough Owner's Manual guides the installer through each step of the process.
The frequency of pre-filter cleaning or replacement depends on the clarity of the feed water and is necessary when the system automatically shuts off at an inlet pressure of 6 psi.
