Common Water Problems — Direct Impact on Health & Production
Well Water / Groundwater
- Sediment, suspended solids, rust, manganese
- High hardness — scale buildup, pipe blockage
- Bacteria, viruses, E. coli
- Nitrate, fluoride, arsenic contamination risk
- Brackish water — high salt / high TDS
Municipal Tap Water
- Aging pipeline — rust, turbidity, secondary contamination
- Intermittent supply — storage tank contamination
- Insufficient residual chlorine or unpleasant odor
- Unstable microbial indicators
Consequences of Untreated Water
- Household: Poor taste, diarrhea risk, appliance scaling
- Hotel / Retail: Bad drinking experience, customer complaints
- Food / Slaughter: Microbial exceedance, product rejection
- Boiler: Scale, corrosion, rising energy cost, burst pipes
- Bottled Water: Conductivity exceedance, poor taste, short shelf life

Engineered Water Treatment Technologies
From membrane separation to ion exchange, we engineer every stage for maximum efficiency and reliability.
Ultrafiltration (UF)
Membrane separation at room temperature and low pressure. Pore size 0.1–0.03 μm, MWCO 1,000–200,000 Da. Effectively removes colloids, bacteria, pyrogens & organics — virtually no salt rejection.
Reverse Osmosis (RO)
The most advanced & energy-efficient membrane technology. Pore size 0.0001 μm. Removes dissolved salts, colloids, microorganisms, organics & heavy metals with 97–98% rejection. Desalination rate 95–99.6%.
Water Softener
Ion exchange technology — resin Na⁺ swaps with Ca²⁺ / Mg²⁺ in water. Regenerated with iodine-free brine. Prevents scale buildup in boilers, cooling systems, water heaters & pipelines.
Pretreatment System
Multi-stage protection: Raw water tank (pressure stabilization) → Quartz sand filter (sediment) → Activated carbon (chlorine ≤0.1 mg/L) → Cartridge filter (5 μm) → Anti-scale dosing → High-pressure pump.
EDI Ultrapure Water
Multi-stage deep purification removing ions, organics, microorganisms, particles, bacteria & pyrogens. Final product resistivity ≥18.2 MΩ·cm. For semiconductors, pharma, labs, solar & electroplating.
Disinfection & Water Supply
UV sterilization (microbial inactivation), food-grade pipeline circulation (anti-stagnation), non-negative pressure supply (municipal connection), constant-pressure VFD supply (adaptive pump speed).

FAQ
Q1: Can well water be used for drinking directly?
Not recommended. Well water may contain sediment, bacteria, viruses, heavy metals & salts. Test first, then choose UF or RO treatment.
Q2: How to choose between UF and RO?
UF removes sediment, colloids & bacteria but not salts or heavy metals. RO removes salts, heavy metals & microorganisms. If well water has high TDS, high hardness or heavy metal risk — choose RO.
Q3: Can it work with unstable voltage?
Yes — optional voltage stabilizer and wide-voltage control cabinet available (220V/380V).
Q4: How often does the equipment need maintenance?
Filter cartridges: every 3–6 months. RO membrane: every 1–3 years. Actual schedule depends on water quality & usage volume.
Q5: Can the equipment be customized?
Yes — 0.25–200 T/H customization available. OEM/ODM welcome.
Q6: Can you send engineers for installation?
We provide installation guidance, video training & remote commissioning. Engineers can also be dispatched overseas for on-site service.
