Borehole Water Purification System Product Guide
A borehole water purification system is designed to transform underground water with high salinity, minerals, or impurities into safe, clean, and reliable drinking water. In regions where freshwater is scarce and groundwater quality varies greatly, this system provides a practical, efficient, and cost-effective solution for both residential and industrial users.
Unlike a sea water purification system or a salt water purification system, which deal mainly with high-TDS seawater, borehole treatment focuses on minerals, hardness, iron, manganese, and varying salinity depending on geological conditions. This makes the system highly flexible and customizable.
Why Borehole Water Needs Purification
Borehole (well) water often contains complex contaminants:
-
High TDS (salts and dissolved solids)
-
Hardness minerals (Ca, Mg)
-
Iron and manganese
-
Sediments, clay, turbidity
-
Microorganisms
-
Heavy metals depending on geology
If not treated, these contaminants can damage pipelines, corrode equipment, reduce water quality, and pose health risks.
A borehole water purification system solves these issues using a combination of pre-filtration and advanced membrane technology.
How a Borehole Water Purification System Works
Although every location has different water conditions, the core treatment steps generally follow this structure:
1. Raw Water Pumping
A submersible pump lifts water from the borehole and feeds it into the treatment line under stable pressure.
2. Pre-Filtration & Sediment Removal
Multimedia or sand filters eliminate larger particles, mud, and suspended solids.
This protects downstream components and ensures stable flow.
3. Activated Carbon Treatment
Removes odor, color, organic substances, chlorine (if present), and improves taste.
4. Water Softening (Optional Based on Hardness)
A softener exchanges calcium and magnesium ions, preventing scale buildup in RO membranes.
This is especially useful in borehole systems with high hardness.
5. Cartridge Filtration (5μm)
Fine filtration removes remaining micro-particles, ensuring consistent pre-treatment quality.
6. Reverse Osmosis (RO) – Core Purification Step
RO membranes remove:
-
99% of dissolved salts
-
Heavy metals
-
Fluoride
-
Nitrates
-
Bacteria and microorganisms
This step transforms raw borehole water into clean, low-TDS purified water.
The same RO principle is also used in sea water purification systems and salt water purification systems, but with different membrane pressures depending on the salinity level.
7. Final Sterilization (UV or Ozone)
Provides safe, long-term microbial protection.
Typical Applications
-
Residential drinking water supply
-
Agricultural irrigation (reducing soil salinity risk)
-
Livestock farms
-
Bottled water production
-
Small communities and rural villages
-
Industrial steam boilers, car washes, laundry facilities
The system is flexible and can be adjusted for slightly saline borehole water, similar to a compact salt water purification system.
Why Use RO for Borehole Water Instead of Other Methods?
RO is the most effective technology when water contains:
-
High TDS
-
Fluoride
-
Nitrates
-
Hardness + salinity mixed
-
Heavy metals
Other methods can remove parts of the contaminants, but only RO produces reliably low-TDS pure water that meets international drinking standards.
