Summer brings heavy rainfall, making well water more turbid than usual. After a few days, it may appear clear again, leading to continued use. However, observations show that 85% of well water retains sediment for 7-15 days after rain. Even after sedimentation, the surface may appear clear, but the iron and manganese ions remain excessive. Using this water is extremely harmful to health. Well water must be filtered using professional well water filtration equipment to meet drinking water standards.
What is filtered in well water and how is it filtered?
The first layer is quartz sand. Don't be fooled by claims of "refined quartz sand." Look at the particle size—0.4-0.8mm is ideal. Too fine, and it will clog; too coarse, and it will leak. The type we use can filter over 90% of sediment and rust per cubic meter. This isn't an exaggeration; it's based on actual measurements. Take a beaker of water, let it sit for three days, and the layer of sediment at the bottom will be thicker than the dust on your balcony.
The second layer is activated carbon. Don't underestimate this black activated carbon; it not only absorbs odors but also the humic acid that turns your water yellow. After a village in Weinan upgraded its equipment, an old lady said, "The water doesn't taste earthy anymore; it tastes like spring water." —That's valuable feedback. Not all activated carbon is the same. Coal-based activated carbon is more resistant to sediment and has a longer lifespan than coconut shell activated carbon, and crucially, it's cheaper. Most importantly, it's backwashing. I've seen too many people take shortcuts, disassembling the filter tank only once a month, exhausting themselves, and still not getting it properly cleaned. Our equipment's backwashing is automatic. When the pressure difference reaches 0.07 MPa, the valve clicks, and the water flows in reverse, flushing out all the sediment from the sand. It's fully automatic in 3 minutes; you don't even need to touch it. The filter media can last for three more years, saving not just money but lives—who wants to climb into tanks every day to remove sediment?
Bigger isn't always better equipment. A 5-ton/hour water supply is sufficient for a livestock farm, while rural centralized water supply systems require 20 tons, and factory production lines may need 50 tons. We don't make "all-purpose machines," we only make "tailor-made solutions." From wellhead to tap, the complete system is provided: pre-sedimentation tank, multi-media filtration, pressure stabilizing tank, and ultraviolet sterilization—all in one step. This concludes our introduction to well water filtration equipment.

DIEN Water Treatment is a water treatment equipment manufacturer with 10 years of experience. We manufacture all filter media, valves, and tanks ourselves. Before leaving the factory, each piece of equipment undergoes a final test by our technicians. Every data point—water quality, pressure, and flow rate—is recorded to ensure it meets standards before shipment. After installation, the equipment is tested again to ensure we provide you with qualified, high-quality equipment.
