Your Benefits of the Watermakers Systems

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?

Installing your Reverse Osmosis System

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.

From Theory to Practice: Decoding Reverse Osmosis Mechanisms

The theory in short:

  • Osmosis: natural process involving semi-permeable membrane
  • Desalination: balances solution concentrations through membrane
  • Reverse Osmosis: high pressure reverses flow for purer solution
  • Feedwater concentration increases in Reverse Osmosis
  • Operating pressure: at least double membrane's osmotic pressure
  • Seawater composition: sodium chloride, calcium, sulfate
  • Total Dissolved Solids (TDS): averages 32,000 to 35,000 ppm.

Let’s take a deep dive into the theory.

Understanding Osmosis: Nature's Filtering Process

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.

Reverse Osmosis: Engineering Pure Water Solutions

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 Composition: Total Dissolved Solids Overview

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%.

Membrane Magic: Inside the High-Tech World of Reverse Osmosis

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).

Maintaining RO Efficiency: Environmental Factors at Play

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.
