How to Choose Large Scale Water Purification System
A Large Scale Water Purification System is an industrial or municipal water treatment solution designed to produce a high volume of clean, safe, and stable-quality water. It removes suspended solids, sediments, dissolved salts, heavy metals, organic matter, bacteria, and viruses from raw water sources such as river water, well water, brackish water, or seawater.
These systems are widely used in factories, communities, water stations, hotels, bottling plants, food processing, and agricultural irrigation.
Advantages of Large Scale Water Purification System
-
High output capacity – suitable for continuous 24/7 operation
-
Stable water quality – consistent TDS and purity
-
Efficient removal of contaminants – bacteria, salts, metals, organics
-
Energy-saving design – high-efficiency pumps & membranes
-
Long lifespan – durable materials (SS304/316)
-
Fully automatic control – PLC, flowmeters, pressure gauges
-
Easy installation – optional containerized, plug-and-play
-
Low operating cost
Process Flow of Large Scale Water Purification System
Raw water tank—booster pump—multi-media filter—activated carbon filter—softening filter—scale inhibitor—reduction dosing device—precision filter—high-pressure pump—RO—UV—product water tank
Process Flow Design Principles
The design of a water purification process depends on multiple factors, including the raw water quality, required water standard, and intended application.
-
For simple requirements and relatively clean raw water, the process flow can be straightforward.
-
For poor-quality water that needs very low TDS or ultrapure water, the process will include additional professional components and treatment steps to meet the required standard.
In other words, the process is always customized to ensure optimal water quality while keeping the system cost-effective and efficient.

How to Choose the Right Large Scale Water Purification System？
1.Identify raw water type
River, well, brackish, or seawater → each requires different membranes and pretreatment steps.
2.Check water test report
Focus on TDS, turbidity, hardness, iron, manganese, and organics to determine the correct treatment design.
3.Define required capacity
Calculate daily usage and apply a safety factor to ensure stable supply.
4.Determine water quality standard
Options include drinking water, industrial process water, or ultrapure water.
5.Choose suitable purification process
UF for low-TDS surface water
RO for brackish water
SWRO for seawater
RO + EDI for ultrapure water applications
6.Select preferred installation type
Skid-mounted systems or fully containerized units for plug-and-play use.
7.Consider power availability
Check voltage, frequency, and whether diesel generator or solar power is required.
