Last summer, Mr. Zhang, the factory manager of a food factory in Xianyang, came to our DIEN Water Treatment plant, his face full of anger. Six months prior, he had spent 23.000 yuan online to buy a "fully automatic well water purification system." For the first two months after installation, the water quality was acceptable, but starting in the third month, a layer of yellow rust formed on the walls of the workshop's water pipes, and the iron content in the effluent soared to 0.55 mg/L, 1.8 times the national standard. The production line was forced to shut down for two days, resulting in a loss of 40.000 yuan just from losses. He disassembled the equipment for us to see—the filter media was dyed iron ore sand, with an MnO₂ content of only 22%. The aeration chamber was simply a PVC pipe, which he claimed relied on "natural air intake from the water pump." I squatted in front of the equipment, squeezed the filter media with my hand, and it was all powder; my fingernails were filled with rust-colored mud. This wasn't a purification system; it was a rust collector.
Well Water Filtration Equipment
Our DIEN Water Treatment system comes standard with a 1.2-meter cascading aeration chamber for each well water purification unit. Water cascading from a height absorbs 800 liters of air per ton, pushing dissolved oxygen levels above 4.5 mg/L. The filter media uses natural manganese sand directly sourced from the Yulin mining area, with a measured MnO₂ content of 38.7% and a particle size of 0.6–2.0 mm. Its activity remains undiminished after backwashing. The tank is made of 316L medical-grade stainless steel with a food-grade epoxy lining—Xi'an groundwater has large pH fluctuations and high chloride ion levels; ordinary tanks rust through within two years, but ours hasn't needed replacement in 12 years.
Do you think low prices mean good value for well water filtration equipment? Ordinary equipment is priced between 8800 and 23800 yuan, using inferior manganese sand, carbon steel tanks, and offering no warranty. Our equipment has transparent pricing, a complete range of 0.5–5 tons/day manufactured in-house, without rebranding or outsourcing. The money you save could buy three monitoring systems.
The price of well water filtration equipment isn't determined by the listed price, but by whether it will still be usable after three years. At Dean Water Treatment, we've focused on one thing for 10 years: building durable water treatment systems for factories. We manufacture all categories ourselves: iron and manganese removal equipment, water softening equipment (single valve double tank/stainless steel/carbon steel), reverse osmosis equipment (single-stage/double-stage/industrial/laboratory), EDI ultrapure water systems, seawater desalination units, containerized integrated water stations, ultrafiltration equipment, wastewater treatment equipment, and boiler feedwater systems—covering the entire supply chain, without outsourcing. We offer a 1-year warranty and 24-hour after-sales support. For local Xi'an customers, our engineers will arrive at your factory within 2 hours for free commissioning; we don't even sell equipment.
