Neo 18x65 Size Water Treatment Water Softener Vessels Plant
Neo 18×65 FRP Water Treatment Vessel – Capacity, Flow Rate & Specifications
The Neo 18×65 FRP (Fiberglass Reinforced Plastic) Water Treatment Vessel is widely used in water filtration, water softening, and carbon filtration systems for residential, commercial, and industrial applications. This vessel is designed to provide strong performance, high durability, and reliable operation in various water treatment plants.
An 18×65 FRP vessel typically has a total internal volume between 235 and 269 liters (approximately 62–71 gallons). The vessel is constructed from high-strength fiberglass reinforced plastic, which makes it corrosion-resistant, lightweight, and capable of handling high operating pressure. Because of these properties, FRP vessels are commonly used in water treatment plants instead of traditional metal tanks.
Typical Hourly Flow Rate
The water flow rate of an 18×65 vessel depends on the type of filtration media used inside the vessel and the specific water treatment application. Different media require different contact times with water to achieve the best purification performance.
1. Filtration (Sand / Multimedia Filter)
When the vessel is used for sand filtration or multimedia filtration, the recommended flow rate is approximately 2,500 – 3,000 liters per hour (LPH) for standard commercial operation. This allows the filter media to effectively remove suspended particles, sediments, turbidity, and impurities from water.
2. Water Softening (Resin Media)
For water softening applications, the flow rate can generally be higher because ion-exchange resin works efficiently with proper contact time. An 18×65 water softener vessel is typically rated for around 3,000 – 4,500 liters per hour (LPH) depending on the control valve used, such as Clack WS1 or Culligan CTM. This makes the vessel suitable for hotels, apartments, industries, and boiler feed water systems where continuous soft water supply is required.
3. Activated Carbon Filtration
When the vessel is used for activated carbon filtration, the recommended flow rate is usually lower to allow enough contact time for the removal of chlorine, odor, color, and organic chemicals. The typical flow rate in this case is around 1,500 – 2,000 liters per hour (LPH).

Duplex System for Continuous Operation
For heavy-duty commercial or industrial water treatment plants, the Neo 18×65 vessels are often installed in duplex (twin-tank) configurations. In this setup, one vessel continues supplying treated water while the other undergoes regeneration or backwashing. This ensures a continuous water supply without interruption, which is important for industries, hotels, hospitals, and large residential buildings.
