500 LPH RO PLANT

A 500 liters per hour (LPH) Reverse Osmosis (RO) plant typically includes components like a raw water pump, multimedia filters (activated carbon and sand filters), a high-pressure pump, RO membranes, and a control panel. Specifications vary by manufacturer, but generally, these plants are designed for brackish or slightly contaminated water, with a maximum Total Dissolved Solids (TDS) level of around 2000-3000 ppm.

Here's a more detailed breakdown of the components and specifications:

1. Raw Water Pump:

Purpose: To draw water from the source and feed it into the filtration system.

Capacity: Often around 0.5 HP, with a head of 15 meters (or more), according to some commercial RO plant providers.

Make: Kirloskar or Crompton Greaves are common brands, according to a technical document.

2. Multimedia Filters (Activated Carbon and Sand Filters):

Purpose:

To remove suspended solids, dirt, iron, and chlorine, protecting the RO membrane from fouling.

Media:

Typically include activated carbon and sand, according to some commercial RO plant providers.

Configuration:

Often housed in FRP (Fiber Reinforced Plastic) vessels, with multi-port valves for backwashing.

3. High-Pressure Pump:

Purpose:

To pressurize the water to overcome the osmotic pressure of the RO membrane, ensuring efficient water filtration.

Capacity:

Typically 1.0-2.0 kW, with a flow rate of 3500 liters per hour and a head of 125 meters.

Make:

CRI or Sumo are common brands, according to some commercial RO plant providers.

4. RO Membranes:

Purpose: To remove dissolved salts, minerals, and other impurities from the water.

Type: Typically thin-film composite (TFC) or polyamide membranes.

Size: 4040 (4-inch diameter, 40-inch length) is a common size for commercial RO plants, according to some commercial RO plant providers.

Number: 500 LPH systems usually have two membranes in a single housing.

5. Control Panel:

Purpose: To control and monitor the operation of the RO plant, including pressure, flow rate, and other parameters.

Automation: Can be semi-automatic or fully automatic, depending on the system.

6. Other Components:

Micron filter: To remove finer suspended particles.

Dosing pump: To add chemicals for pre-treatment or cleaning.

Pressure gauges: To monitor pressure at various points.

Flow meters: To measure the flow rate of water.

RO membrane housing: Typically made of stainless steel or FRP.

7. Recommended Conditions:

Inlet TDS: Up to 3000 ppm, according to some commercial RO plant providers.
