What the system is and what problem it solves

The ULT RO 18,000 GPD Reverse Osmosis System is engineered for applications that require a reliable supply of purified water at a higher daily output. Designed for industrial facilities, commercial buildings, and high-demand environments, the system provides up to 18,000 gallons per day of treated water.

Its multi-stage purification process helps remove dissolved solids, particulates, and various waterborne impurities. This makes the system suitable for locations where feedwater quality is inconsistent or where municipal supply does not meet the required purity standards. Built with durable components, the system ensures long-term operational stability with minimal maintenance requirements.

Process Design & Operating Philosophy

The 18,000 GPD RO system operates on a multi-stage membrane separation process designed to maintain consistent output quality while managing variations in feedwater conditions. The filtration stages work together to reduce contaminants and protect the membranes from premature fouling.

The system is designed to operate efficiently, using controlled hydraulic balance across membrane stages to maintain stable performance. Energy consumption is minimized through optimized pump sizing and efficient membrane selection. Routine maintenance is simplified through an accessible layout and user-friendly design.

Design Basis & Engineering Assumptions

Parameter	Design Basis
Water Production Capacity	18,000 GPD
Permeate Flow Rate	72 m³/day at 25°C
Design Recovery	50–60%
Salt Rejection	95–98%
Membrane Type	CSM 8040 (400 ft² × 3 pcs)
Operating Pressure	Determined by feedwater TDS and temperature
Pressure Vessels	FRP 8040 × 3 pcs
Operating Temperature Basis	25°C

Final design is confirmed after feedwater analysis and site evaluation.

System Configuration

The ULT RO 18,000 GPD system is supplied as a fully integrated industrial RO unit consisting of:

Three CSM 8040 brackish water RO membranes
Three FRP 8040 pressure vessels
Grundfos high-pressure pump (4 kW, CRI 5-29)
Stainless-steel welded structural frame
High-pressure SUS304 piping
Schedule-80 UPVC low-pressure piping
TK 7-20 cartridge pre-filter
Pure water and drain flow meters
Low-pressure and high-pressure valves
Flush, feed, and adjustment valves
Pressure gauges on the main panel

The layout allows easy access for routine service and maintenance.

Performance Parameters

Parameter	Parameter
Permeate Flow	18,000 GPD
Recovery	50–60%
Salt Rejection	95–98%
Monitoring	Flow meters, pressure gauges, valves

Performance may vary depending on feedwater characteristics and operating conditions.

Pretreatment & Integration Requirements

Pretreatment needs depend on feedwater quality and may include:

Sediment and turbidity reduction
Hardness removal to limit scaling
Iron and manganese reduction
Dechlorination to protect membranes
Removal of oil and grease contaminants

The system can integrate with upstream pre-treatment units and downstream processes like disinfection, remineralization, or blending.
