Water Purification Components

Complete Guide to RO System Filters & Technologies

SEDIMENT FILTER

1 Introduction

A Sediment Filter is the first stage in a Reverse Osmosis (RO) water purification system.

It removes visible and suspended impurities like:

  • Dust
  • Mud
  • Rust
  • Sand
  • Dirt particles

These particles can clog the RO membrane and reduce the efficiency of the purifier.

So, the sediment filter acts as a protective barrier for the rest of the system.

2 Construction / Composition

It is usually a cylindrical cartridge made of polypropylene (PP) fiber or spun fiber.

The filter has micron-sized pores (tiny holes) that trap solid impurities.

Common pore sizes: 5 microns

Advantages

  • Extends the life of RO membrane and carbon filters.
  • Improves overall purification performance.
  • Reduces maintenance cost.
  • Keeps water flow steady.

Main Functions

Function Explanation
Removes Suspended Solids Filters out dust, mud, rust, and other solid particles.
Protects RO Membrane Prevents clogging and extends membrane life.
Improves System Efficiency Ensures smooth water flow through later filters.
Prepares Water for Next Stage Provides cleaner water for chemical purification.

Pre-Carbon Filter (Activated Carbon Filter)

Introduction

A Pre-Carbon Filter is an important stage in an RO (Reverse Osmosis) water purification system.

It is also known as an Activated Carbon Filter or Carbon Block Filter.

Its main role is to remove chlorine, organic impurities, bad taste, and odor from water before it enters the RO membrane.

This helps protect the RO membrane and improves the quality and taste of the final water.

Construction / Composition

The filter is made of Activated Carbon, a special form of carbon treated to have a very large surface area.

  • Activated carbon is obtained from Coconut Shell
  • During manufacturing, the carbon is heated at high temperature

Working Principle

The Pre-Carbon Filter works on the principle of Adsorption.

Adsorption:

It is a surface-based process where impurities stick to the surface of activated carbon rather than dissolving in it.

When water passes through the filter:

  1. Activated carbon attracts and holds chlorine molecules, pesticides, phenols, and other organic chemicals on its surface.
  2. It also neutralizes bad odors and tastes caused by these chemicals.
  3. This ensures that the water entering the RO membrane is clean and chemical-free.

Functions and Importance

Function Description
Chlorine Removal Protects the RO membrane from damage, as chlorine can oxidize and destroy it.
Improves Taste and Odor Removes bad smell and makes water taste.

UF Filter (Ultrafiltration)

Introduction

UF stands for Ultrafiltration.

It is a membrane-based filtration process used to remove bacteria, viruses, and suspended impurities from water.

The UF membrane has very tiny pores (around 0.01 micron) which allow only pure water molecules to pass through while blocking larger particles.

UF filtration works without electricity and is often used:

  • Along with RO and UV (in RO+UF+UV systems), or
  • Alone in gravity-based purifiers.

Main Functions

Function Description
Removes Microorganisms Filters out bacteria, cysts, and some viruses.
Removes Suspended Solids Eliminates visible and invisible particles.
Protects RO System Used before or after RO to improve purity.
Works Without Electricity Uses normal water pressure to operate.
Retains Essential Minerals Does not remove good minerals from water.

Advantages

  • Removes bacteria and germs effectively.
  • Works without electricity.
  • Retains healthy minerals in the water.
  • Requires low maintenance.
  • Makes water clear and safe for drinking.

UV Filter (Ultraviolet) – Complete Details

Introduction

UV stands for Ultraviolet.

A UV filter uses ultraviolet light to kill or inactivate microorganisms in water, such as:

  • Bacteria
  • Viruses
  • Protozoa

Main Functions

Function Explanation
Kills Microorganisms Destroys bacteria, viruses, and protozoa.
Maintains Water Quality Ensures water is microbiologically safe.
No Chemicals Used Uses only UV light, no chlorine or other chemicals.
Does Not Affect Minerals Retains healthy minerals in water.
Fast Process Water is treated instantly while passing through the chamber.

Advantages

  • Kills 99.99% of microorganisms.
  • Safe and chemical-free disinfection.
  • Retains natural minerals in water.
  • Works instantly; no need to store water.

Reverse Osmosis (RO) Membrane

Description

At the heart of your water purifier, our advanced Reverse Osmosis (RO) membrane is engineered to provide the highest level of filtration. It effectively removes up to 99% of impurities, including heavy metals, bacteria, and dissolved salts, ensuring you get safe, clean, and great-tasting water with every glass.

You can trust the purification of your water to the core of your system—our RO membrane. Unlike standard filters, our membranes feature an antibacterial spacer and multi-layered sheets for enhanced performance and longevity. This advanced construction not only delivers cleaner water but also extends the life of your unit. Choose our membrane for:

  • Superior Contaminant Removal
  • High-Quality, Imported Components
  • Enhanced Flow Rate
  • Unrivaled Durability.

Working Principle (How it Works?)

RO works on Reverse Osmosis Technology:

  1. Water is pushed through the membrane under pressure.
  2. Only pure H₂O molecules pass through tiny pores (0.0001 micron).
  3. All dissolved contaminants are flushed out as reject water.

Pore Size:

0.0001 micron → 5000 times smaller than bacteria & 1000 times smaller than viruses.

Operating Temperature: 5℃ - 45℃

Key Advantages of a High-Quality RO Membrane

  • 99.9% purification efficiency
  • Long membrane life (up to 24 months)
  • Consistent low-TDS, great-tasting water
  • High chemical and biological resistance
  • Works in domestic RO systems
  • Suitable for borewell, municipal, or tanker water
  • Environmentally friendly — reduces bottled water usage
  • Supported water TDS level max.-3000 ppm

MTDS (Manual Total Dissolved Solids Controller)

Introduction

MTDS stands for Manual Total Dissolved Solids Controller.

It is a small mixing valve or flow control device installed in an RO water purifier that allows you to manually adjust the TDS level of the purified water.

This is important because RO removes nearly all dissolved minerals, making water very pure but sometimes too low in minerals — which can taste flat or be less healthy for daily consumption.

MTDS solves this by mixing a small portion of raw (unfiltered) water with RO-purified water, restoring minerals and taste.

Benefits of MTDS System

Customizable Taste & Mineral Balance Adjusts TDS manually to get the desired taste — not too bland, not too salty.
Suitable for different water sources (borewell, municipal, tanker).
Healthier Drinking Water Retains essential minerals like calcium, magnesium, sodium, and potassium.
Prevents over-purification (ultra-low TDS water can taste flat and be less hydrating).
Extended Membrane Life Reduces load on post-mineral cartridges (if installed).
Allows balanced flow and better system efficiency.
Economic & Simple Manual control — no electronic parts or sensors.
Low maintenance and long-lasting component.

Advantages of Having MTDS in RO Purifier

  • Control over water taste and TDS
  • Restores natural mineral balance
  • Prevents over-purification
  • Extends RO membrane life
  • Low maintenance and affordable
Note: MTDS is completely an optional component. Muddy, salty and waste water is not recommended.

Prefilter (Sediment Filter / Pre-filtration Stage)

Overview

A Prefilter (also called a Sediment Filter or PP Filter) is the first stage of filtration in an RO (Reverse Osmosis) water purifier.

It removes large suspended particles such as:

  • Dust
  • Rust
  • Mud
  • Sand
  • Silt
  • Scale
  • Other visible impurities

By doing this, it protects the RO membrane and other internal filters from clogging or damage.

Purpose of the Prefilter

  • Acts as the first line of defense in the purification process.
  • Ensures that only clean, particle-free water reaches the activated carbon and RO membrane.
  • Greatly extends membrane life and maintains system pressure.
  • Reduces maintenance cost and improves purification
