What the system is and what problem it solves?

The 20,000 GPD Brackish Water Reverse Osmosis (BWRO) Plant is engineered to desalinate brackish groundwater and surface water sources containing elevated levels of dissolved salts. It provides stable permeate quality even when feedwater salinity fluctuates, making it suitable for areas where municipal supply is unavailable or does not meet required standards.

Variations in TDS and ionic composition increase osmotic pressure and affect membrane performance. This RO plant is designed with conservative flux settings, controlled recovery, and durable mechanical components to ensure long-term reliability and consistent treated water output.

Process Design & Operating Philosophy

High-TDS brackish feedwater requires increased operating pressure and careful hydraulic balancing to maintain membrane performance. This system is designed to manage those conditions by:

Distributing hydraulic flux evenly across membrane stages
Reducing fouling through controlled recovery
Maintaining stable differential pressure
Supporting long-term membrane performance with proper pretreatment

Where feed salinity approaches upper brackish limits, the system may operate at reduced recovery to maintain permeate water quality and minimize scaling.

System projections include long-term performance considerations such as fouling factors, temperature correction, and salt passage increase.

Design Basis & Engineering Assumptions

Parameter	Design Basis
Feedwater TDS	2,000 – 7,000 mg/L (higher TDS possible with design modification)
Nominal Capacity	20,000 GPD (≈ 72–75 m³/day)
Design Recovery	50 – 60%
Salt Rejection	95 – 98%
Design Temperature	25°C (temperature correction applied)
Operating Pressure	Determined by TDS, recovery, and temperature
System Type	Single-pass brackish RO

Final design parameters are confirmed following detailed feedwater analysis and site evaluation.

System Configuration

The 20,000 GPD BWRO system is supplied as a skid-mounted desalination unit integrating:

CSM 8040 TFC brackish water RO membranes (3 pcs)
FRP 8040 membrane pressure vessels (3 pcs)
Grundfos CRI 5-29 high-pressure pump (4 kW, 380V, 50 Hz)
Stainless steel welded structural skid
High-pressure SUS304 piping
Schedule 80 UPVC low-pressure piping
TK 7-20 cartridge pre-filter
Pure water and drain flow meters
Low- and high-pressure valves
Pressure gauges on main control panel
Flush, feed, and adjust valves

The open-access skid design ensures easy inspection, operation, and maintenance.

Performance Parameters

Parameter	Parameter
Parameter Flow	20,000 GPD
Recovery	50 – 60%
Salt Rejection	95 – 98%
Feed Temperature Basis	25°C
Operating Mode	Continuous
Monitoring	Feed, permeate, and concentrate flows

Actual performance is verified during commissioning and optimized based on site conditions.

Pretreatment & Integration Requirements

Pretreatment is critical to maintaining membrane integrity and long-term performance. Depending on feedwater quality, pretreatment may include:

Removal of suspended solids and turbidity
Iron and manganese reduction
Hardness control to minimize scaling
Dechlorination to protect RO membranes
Exclusion of oil and grease contaminants

The system is compatible with upstream treatment units and downstream processes such as disinfection, remineralization, or blending.
