1. Raw Water Pump:

 The raw water pump is the first component in the purification system. It draws water from the source (e.g., a well, river, or storage tank) and delivers it to the subsequent stages of purification under pressure.

• Media Filter:

A media filter is a device used to eliminate impurities from a fluid, typically water or air, by passing it through a filtering material. These filters are widely used in various applications, including industrial processes, water treatment, and air purification. The filtering material, known as the media, can vary depending on the specific use case and the type of impurities being targeted. Here are the primary types of media filters and their applications:

Types of Media Filters

• Description: It use activated carbon to adsorb organic compounds, chlorine, and other contaminants.
• Application: Widely used in water purification, air purifiers, and industrial processes to remove odors, toxins, and impurities.

• Cartridge Filters:
• Description: It employ replaceable cartridges made of various materials (e.g., paper, fabric, or membrane) to trap particles.
• Application: It is used in residential and commercial water filtration systems, as well as in industrial applications.
• Bag Filters:
• Description: Contain filter bags made of fabric or felt to capture particles from liquids or gases.
• Application: Common in industrial liquid filtration and dust collection systems.
• Ceramic Filters:
• Description: It utilize porous ceramic materials to filter out bacteria, sediments, and other impurities.
• Application: Often used in portable water filters and point-of-use water purification systems.
• Multimedia Filters:
• Description: Combine multiple layers of different filtering materials (e.g., gravel, sand, anthracite) to improve filtration efficiency.
• Application: It is used in water treatment to remove a wide range of particle sizes and types

Specifications:

• Carbon Filter:

The activated carbon filter removes chlorine, organic compounds, and other chemicals that affect water taste and odor. Activated carbon has a high surface area, which makes it effective in adsorption.

Specifications:

• The micron cartridge filter further polishes the water by removing fine particles and microorganisms. It typically contains replaceable cartridges rated at 5 microns or less.

Dosing System:

Chemical dosing system is a complete set of equipment with dosing, mixing, transporting liquid and automatic control. It is also called chemical feed system or dosing machine. It is used for raw water of power plant, boiler feed water, oil field ground gathering and transportation dehydration treatment system, petrochemical dosing system and wastewater treatment system.

 Specifications:

High Pressure Pump:

The high-pressure pump increases the water pressure to the level required for the RO membranes to function productively. This is usually a multi-stage pump capable of providing pressures up to 150-200 psi.

Specifications:

RO Membrane:

The core component of the RO system, the membranes remove dissolved salts, bacteria, and other impurities. Typically, thin-film composite (TFC) membranes are used, which offer high rejection rates and durability.

Specifications:

RO Pressure Tube:

RO Pressure Tube work is to monitor the pressure at various stages in the system to ensure proper operation. It is typically installed before and after the high-pressure pump and before the RO membranes.

Specifications:

Pipe Valve:

This is a fitting or adapter is used in pipe systems to connect sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating fluid flow.

Specifications:

• With Pipe : 1 Set

Electrical Panal:

This is the brain of the RO system, it controls the operation of pumps, valves, and monitors system performance. It includes timers, switches, and alarms for easy operation and maintenance.

Specifications:

• Complete starters, overload relays, single phase prevention for pump. Ø
• MCB’s , indicating lights
• Push buttons
• Rocker Switches for Dozers
• Incomers, Auto- Manual Switches

Instrumentation:

Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities. It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory.

Specifications:

Plumbing & Fitting:

A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow.

Specifications:

• Pipelines upvc
• NRV’s pressure relief valves ,
• Where needed

Here are the following assembling Step-by-Step procedure are mentioned below:

Now that we understand the components, let's move on to the assembly process.

Step 1: Selection of Location:

First of all you have a clean, dry, and well-ventilated space for the installation. The area should have access to an electrical supply and a water source.

Step 2: Install the Raw Water Pump

After that, we have to mount the raw water pump securely near the water source. Connect the inlet of the pump to the raw water source using appropriate piping and fittings and make sure all connections are leak-proof.

Step 3: Set Up the Sand Filter

Now we will install the sand filter next in line and connect the outlet of the raw water pump to the inlet of the sand filter. Ensure the filter is filled with the correct media (sand, gravel, anthracite) and backwash it to remove any fines before use.

Step 4: Install the Activated Carbon Filter

Position the activated carbon filter after the sand filter. Connect the outlet of the sand filter to the inlet of the carbon filter. Ensure the filter is filled with activated carbon granules and is backwashed to remove air and dust.

Step 5: Install the Micron Cartridge Filter

Mount the micron cartridge filter after the carbon filter. Connect the outlet of the carbon filter to the inlet of the micron filter. Ensure the cartridge is properly seated and the housing is sealed.

Step 6: Connect the High-Pressure Pump

Position the high-pressure pump after the micron cartridge filter. Connect the outlet of the micron filter to the inlet of the high-pressure pump. Ensure all connections are tight and leak-proof.

Step 7: Install the RO Membrane Housing and Membranes

Install the RO membrane housing after the high-pressure pump. Connect the outlet of the high-pressure pump to the inlet of the RO membrane housing. Insert the RO membranes into the housing, ensuring they are properly seated and sealed.

Step 8: Attach the Pressure Gauges and Flow Meters

Install pressure gauges before and after the high-pressure pump, and before the RO membranes. Install flow meters at the inlet and outlet of the RO system. These instruments will help monitor system performance.

Step 9: Install the Solenoid Valves

Position solenoid valves at strategic points in the system, such as the inlet, before the high-pressure pump, and at the reject water outlet. Connect these valves to the control panel for automated operation.

Mount the control panel in a convenient location. Connect all electrical components (pumps, solenoid valves) to the control panel. Set the desired operating parameters and test the panel to ensure it controls the system correctly.

Step 11: Install the Reject Water Flow Regulator

Connect the reject water outlet from the RO membrane housing to the reject water flow regulator. Adjust the regulator to control the flow of reject water and maintain the desired system pressure.

Step 12: Optional UV Sterilizer

If using a UV sterilizer, install it after the RO system. Connect the outlet of the RO system to the inlet of the UV sterilizer. Ensure the UV lamp is functioning correctly and replace it as per manufacturer recommendations.

Step 13: Connect the Storage Tank

Position the storage tank near the system. Connect the outlet of the RO system (or UV sterilizer if used) to the storage tank. Ensure the tank is clean and made from food-grade materials.

Step 14: Final Piping and Fittings

Complete all piping and fittings to ensure a closed loop system. Check all connections for leaks and tighten as necessary. Use Teflon tape on threaded connections to prevent leaks.
