A water treatment project in Indonesia
Indonesian customers need a water treatment design for residential water purification. The water source is underground well water. After taking water samples for testing, it was found that the water turbidity was very
high and the iron content was also high, both of which exceeded the local limit. A water purification equipment was needed to reduce the turbidity and iron content.
Water sample turbidity: 56.6 NTU, local limit 25 NTU
Water sample iron content: 6.61 mg/L, local limit 1mg/L
Requirement: water turbidity and iron content below the limit, remove heavy metals, viruses and bacteria (E. coli), and the purified water should meets the standard of domestic water for daily use.Water flow: 36000LPH / 10LPS And also the whole system should be installed in a 20GP container, to
make it a mobile containerized water treatment system.
well water sample quality
System design
According to customer raw water quality and requirements, systemoverall design is as follows:Feed water pump +Iron removal filter + disc filter + Ultra-filtration
machine +CIP system
Power supply: 380V 50Hz 3phase
Feed water flow: 38000LPH
Purified water flow: 36000LPH
Recovery rate: around 95%

Water production testing
Purified water testing
(see attached local third-party testing conclusion report)
Well water source sample
Turbidity shows 56.6 NTU, above the threshold of 25 NTU.
Iron content shows 6.61 mg/L, above the threshold of 1 mg/L.
Results after passing through manual filtration with the WIL UFF72 pump:
Turbidity has decreased, with a value of 0.58 NTU.
Iron content has decreased to 0.437 mg/L.
Conclusion:
With the above conditions, system is running well and the purified watercould meet the local standards and customer’s requirements.

An IBC (Intermediate Bulk Container) tank is a robust, reusable industrial-grade vessel designed for the storage and transport of liquids, powders, and granules. Its space-efficient cubic shape and integrated pallet base make it ideal for easy handling and stacking, offering a cost-effective solution for bulk quantities.
UV Water Sterilizer Systems are advanced water purification devices that utilize ultraviolet (UV) light to eliminate harmful microorganisms such as bacteria, viruses, and protozoa from water. These systems are highly effective, environmentally friendly, and do not require the use of chemicals, making them a popular choice for both residential and commercial applications. UV sterilizers are often used in conjunction with other filtration methods, such as reverse osmosis or carbon filters, to ensure comprehensive water treatment. They are easy to install, require minimal maintenance, and provide a reliable method for ensuring safe and clean drinking water.
