250 LPH RO PLANT
Description
A typical 250 LPH RO plant specification includes a multistage filtration system, a high-pressure pump, and RO membranes to process water. Key components are the Feed Pump, Pressure Sand Filter (PSF), Activated Carbon Filter (ACF), and a Micron Cartridge Filter (5-micron) before the high-pressure pump and RO membranes. A control panel with necessary switches, pressure gauges, and flow meters is also included, along with options for automatic flushing to extend membrane life.
Key Components & Specifications
Raw Water Feed Pump:
A pump (e.g., Kirloskar, Sumo) to provide initial water flow to the pre-filters.
Pre-Filtration:
Pressure Sand Filter (PSF): Removes suspended solids using graded pebbles and sand in an FRP tank.
Activated Carbon Filter (ACF): Adsorbs dissolved organic compounds and chlorine.
Cartridge/Micron Filter: Removes finer particles, typically down to 5 microns, before the high-pressure pump to protect the membranes.
High-Pressure Pump:
A multistage, centrifugal pump (e.g., CRI, Sumo) that raises the water pressure to force it through the RO membranes.
RO Membranes & Housing:
These are the heart of the system, separating purified water from dissolved salts. They are typically housed in a pressure vessel made of FRP or stainless steel.
Dosing Pump:
A pump for precise dosing of antiscalant chemicals to prevent scaling on the membrane surface.
Control System:
Control Panel: Manages the operation of the pumps and valves.
Pressure Gauges: Monitor pressure throughout the system.
Rotameter/Flow Meter: Measures the flow rate of purified water.
Auto Flush System: An optional feature that uses a timer to automatically flush the membranes to prolong their life.
Plumbing & Skid:
All components are mounted on a robust skid, often made of stainless steel for durability and hygiene.
Typical Performance
Product Water Flow Rate: 250 liters per hour.
Input TDS: Can handle TDS levels up to approximately 2000 ppm.
Recovery Rate: Typically 50-60%, depending on the system's design and raw water quality.
Power Supply: Often single-phase.
