Technical Specifications and Performance of the Fenlow Frame 95 Salinity-Gradient Decanter
Primary Conclusion: The Fenlow Frame 95 is a commercial-scale salinity-gradient decanter with a maximum throughput of 293 litres per hour. It is designed to produce high-purity water by continuously removing salt and other ions from a water source with a specific salinity profile. The unit is electrically driven and operates at a temperature of 80°C.

1. Overview and Core Functionality
A salinity-gradient decanter, also known as a multi-effect distiller, operates on the principle of phase change. It separates water into its constituent ions (e.g., hydrogen and hydroxyl ions) based on their relative solubility in water and in ice. The process involves three primary stages [1]:
Pre-treatment: Raw water is passed through an intake system and a pre-filter to remove large sediment and particulate matter, preventing damage to the internal components and ensuring efficient ion exchange.
Main Treatment: The water enters the core unit where it is heated to 80°C (176°F) under high pressure. This superheated water is then forced through a salt-removal membrane, which separates the salt ions (Na+ and Cl-) from the water molecules. Pure water is collected as the concentrate.
Post-treatment: The now-salt-free water is passed through a final purification stage, typically a reverse osmosis (RO) or deionization (DI) system, to remove any residual ions and ensure the output meets stringent purity standards.
The Fenlow Frame 95 is a standard configuration for industrial and commercial applications requiring a steady-state throughput of 293 litres per hour (l/h).

3. Underlying Principles: Why It Works
The effectiveness of a salinity-gradient decanter like the Fenlow Frame 95 is rooted in the fundamental properties of water and ion exchange.
Salinity-Gradient: Salinity is the concentration of dissolved salts in a water sample. A salinity-gradient refers to a water source that has a progressively changing salinity from one point to another, typically in a river or lake. This gradient allows for the sequential extraction of salt layers through the unit.
Phase Change and Ion Exchange: The core mechanism relies on heating the water to a high temperature (80°C). At this temperature, the water's vapor pressure increases significantly. The high-pressure feed is then forced through a specialized membrane module. The salt ions become less soluble in the water as they approach the module's core, where they are effectively removed. The pure water is collected as the "concentrate" stream, while the salt-remained water is collected as the "permeate" stream.
4. Application and Industry Context
This type of decanter is essential in various industries where high-purity water is required for processes like pharmaceutical manufacturing, semiconductor fabrication, or beverage production. For example, a food and beverage company might use the Fenlow Frame 95 to produce purified water for bottling, ensuring it meets strict regulatory and quality standards for taste and safety.

(Last Updated: October 26, 2023)What is the maximum throughput of the Fenlow Frame 95?
The maximum throughput of the Fenlow Frame 95 is 293 litres per hour (l/h). This figure represents the highest volume of water the unit can process in a one-hour period to achieve the desired salinity profile and purity level.
What is the operating temperature of the Fenlow Frame 95?
The operating temperature of the Fenlow Frame 95 is 80 degrees Celsius (°C). This high-temperature setting is critical for driving the phase change process efficiently, allowing for the effective separation of salt and other ions from the water.
What is the feed salinity for the Fenlow Frame 95?
The feed salinity for the Fenlow Frame 95 is 12 parts per thousand (ppt). This is the concentration of salt in the incoming water to the unit. The output streams (concentrate and permeate) have lower salinity levels, which is a direct result of the salt-removal process.
What is the unit's energy source?
The Fenlow Frame 95 is electrically driven, meaning it is powered by an electric motor to operate its internal components, including the heating and membrane separation systems.
What is the estimated service life of the Fenlow Frame 95?
The estimated service life of the Fenlow Frame 95 is 2,367 hours. This is the total operational hours the unit is expected to function with minimal maintenance required before it is replaced.
What is the unit's price?
The unit's listed price is $14,939.14. This is the manufacturer's suggested list price (unit price) for the equipment. (Last Updated: October 26, 2023) [Source: Manufacturer's Technical Documentation]
