What is an Ultrafiltration Plant and How Does it Work?
Water contamination is a growing concern worldwide, with industries, municipalities, and communities seeking advanced solutions to ensure safe and pure water. Among various water treatment technologies, Ultrafiltration Plant have emerged as a highly effective and reliable choice. These systems use semi-permeable membranes to filter out suspended solids, bacteria, and viruses, ensuring consistent water quality.
In India, Kelvin Water Technologies Pvt. Ltd. is one of the leading manufacturers and suppliers of ultrafiltration plants. With a strong focus on innovation, sustainability, and quality, Kelvin Water Technologies delivers advanced UF systems tailored to industrial, commercial, and residential applications.
What is an Ultrafiltration Plant?
An ultrafiltration plant is a membrane filtration system that uses pressure to force water through hollow fiber or flat sheet membranes with pore sizes between 0.01–0.1 microns. Unlike conventional filtration methods, UF plants offer superior removal of microorganisms, organic matter, and suspended solids, while allowing essential minerals to pass through.
It acts as either:
- A standalone water treatment system for drinking and process water, or
- A pre-treatment step before reverse osmosis (RO) to protect RO membranes and improve efficiency.
How Does an Ultrafiltration Plant Work?
1. Pre-Treatment
- Raw water first passes through sand filters, activated carbon filters, or multimedia filters.
- This step removes chlorine, turbidity, and larger particles to protect the UF membranes.
2. UF Membrane Filtration
- Water is pressurized (1–10 bar) and passed through UF membranes.
- Membranes act as a physical barrier that separates contaminants such as:
1. Bacteria and viruses
2. Colloids and suspended solids
3. Algae and organic impurities
3. Filtration Principle
- UF plants work on a size exclusion principle.
- Only clean water and dissolved salts pass through, while impurities remain trapped.
4. Backwashing and Cleaning
- With time, particles accumulate on the membranes.
- The system automatically performs backwashing (reversing flow of water) to clean membranes.
- Periodic CIP (Clean-In-Place) using mild chemicals extends the membrane life.
5. Treated Water Collection
- Purified water (permeate) is collected in a storage tank.
- It can be used directly or further processed via RO, UV, or other advanced treatment methods.
Features of Ultrafiltration Plants
- Removes 99.9% bacteria and viruses.
- Works without chemicals (eco-friendly).
- Provides consistent water quality even if raw water fluctuates.
- Operates at low pressure, making it energy efficient.
- Long membrane lifespan with minimal maintenance.
