High iron and manganese levels in groundwater are a common problem across much of Northwest China. Well water pumped up and left to stand for a while turns yellow, develops a strong rusty odor, and layers of rust clog the pipes, severely reducing water flow. To eradicate this problem completely, choosing a reliable Xi'an manufacturer of iron and manganese removal well water filtration equipment is the first step. Xi'an DIEN Water Treatment is a local, reputable equipment manufacturer with its own 3000-square-meter workshop for material preparation and welding. Their core product is custom-made, non-standard manganese sand filtration systems for removing iron and manganese from well water. They can handle rural centralized drinking water projects, pre-treatment of deep well water in factories, and irrigation water treatment for livestock. Using a mature approach combining aeration oxidation with manganese sand catalytic filtration, iron, manganese, and sediment are removed together, resulting in clean effluent. This makes them the top choice for Shaanxi customers looking for reliable Xi'an iron and manganese removal well water filtration equipment.

Iron and Manganese Removal Well Water Filtration Equipment
Many dealers offer pre-fabricated tanks, which are unsuitable for water sources like those in northern Shaanxi with extremely high iron and manganese concentrations and heavy sediment loads. These tanks quickly clump together, rendering the filter ineffective and causing the water quality to revert to its original state. DIEN Water Treatment avoids this problem. They provide free initial water sampling and testing at the wellhead, measure the pump room area, and determine the process and dimensions based on the iron and manganese levels (click to learn more: Groundwater Iron and Manganese Excess, Principle of Integrated Iron and Manganese Removal Filtration Equipment) and the daily water output. Integrated or split manganese sand filter units are chosen according to the site conditions. The tanks are made of corrosion-resistant fiberglass, filled with high-content natural manganese sand, and equipped with a fully automatic backwashing program, eliminating the need for manual handling of the filter tanks. The entire machine comes with a one- to three-year warranty, clearly stated in black and white in the contract. Maintenance technicians in the Shaanxi northern region, including Yulin, Yan'an, and Baoji, will arrive within 24 hours. From equipment manufacturing to pipeline laying, machine commissioning, and subsequent maintenance, our team will oversee the entire process, preventing rework within a couple of days of completion.
Case Study: Iron and Manganese Removal from Well Water in a Rural Village in Yulin, Shaanxi
Water Quality Issues Before Renovation
A village near Yulin relied entirely on its own deep well water. The local geological formations were rich in minerals. While the well water appeared relatively clear initially, it visibly yellowed after an hour or two, with a layer of yellowish-brown rust residue at the bottom of the cup. Kettles quickly became covered in yellow scale, and the water had a metallic taste. Villagers would get yellow stains when washing clothes and vegetables. The water pumps and pipes in the yards would rust and clog every six months, requiring expensive replacements and disrupting water supply. Elderly people and children drink this water every day, and many complain of stomach discomfort. The villagers have discussed rectification several times, but filtering with gauze and digging sedimentation tanks doesn't address the root cause. They've also consulted several distributors, but the tank dimensions they provided are fixed and simply don't fit in the limited space of the pump house, causing the rectification to be repeatedly delayed.
DIEN Water Treatment Customized Solution
The technical team took water samples from the well; iron levels were 3.8 times higher than the standard, and manganese levels were 3.1 times higher. Since the pump house is narrow and low, they custom-designed a compact, integrated manganese sand filtration system to remove iron and manganese. The inlet first undergoes a pre-filtration of silt to protect the manganese sand from abrasion. The main body uses aeration to fully oxidize the iron and manganese ions, followed by deep interception by the manganese sand layer. Fully automatic timed backwashing eliminates the need for manual intervention. The entire system fits perfectly into the existing space of the pump house, requiring no changes to the civil engineering.

Actual Usage Results After Rectification
After water supply and testing, both iron and manganese levels fell below the "Standards for Drinking Water Quality." The water is clear and bright, the rusty taste is completely gone, kettles and faucets no longer accumulate yellow scale, and the pipes leading to households haven't been clogged once in over a year. The machine runs automatically; a quarterly check of the filter media is all that's needed. The water quality for the entire village has improved significantly. The treated well water is perfectly usable for both daily drinking and watering fruit trees in the yard.
Customer Feedback: Previously, we contacted several out-of-town suppliers, whose prices were inflated, and whose equipment was too large to fit into the pump house. DIEN, a local manufacturer in Xi'an, came to measure the dimensions and immediately created a miniaturized solution. The effect was noticeable the day the water supply was connected. The well water has never turned yellow again, and there's no more rusty taste. The water pump and pipes have been working perfectly for over a year. After-sales service is nearby; they come immediately when needed. They truly cured the entire village's long-standing drinking water problems.
Yellowish well water, a strong rusty smell, and pipes clogged year after year—to get rid of these problems in one go, choose Xi'an's iron and manganese removal well water filtration equipment manufacturer, Dean Water Treatment, the original factory. Their complete manganese sand filtration units are suitable for high-mineralized groundwater in northern Shaanxi, renovation of old well water equipment, and centralized drinking water purification projects in villages and towns. If you're planning well water quality testing or custom filtration equipment, directly contact DIEN's technical staff for a customized iron and manganese removal solution based on your raw water indicators and water usage scale, ensuring long-term control over water quality.
