Product Overview
The Industrial RO Reverse Osmosis Water Filter is a high-purity water treatment device designed for the fertilizer industry’s process water needs. Using advanced reverse osmosis (RO) technology with a 0.0001 μm filtration precision, it removes dissolved salts (e.g., calcium, magnesium), heavy metals (Pb, Cd), and microorganisms from raw water, producing purified water with a total dissolved solids (TDS) value ≤50 ppm. This ensures the quality of fertilizer products (e.g., preventing scaling in granulators from hard water) and protects production equipment from corrosion. Available in modular designs (5-50 m³/h water production), it is suitable for both fertilizer production process water (e.g., dissolving urea) and equipment cleaning water.
Product Features
High Purification Efficiency: The RO membrane (made of composite polyamide) achieves a ≥98% desalination rate and ≥99.9% removal rate of bacteria (e.g., E. coli) and viruses (e.g., adenovirus), meeting the water quality standards for fertilizer production (GB 50050-2020).
Energy-Saving Operation: Adopts a low-pressure RO system (operating pressure 1.2-1.8 MPa) with an energy recovery device, reducing energy consumption by 15-20% compared to traditional RO filters. The specific energy consumption is 0.8-1.2 kWh/m³ of purified water.
Stable Water Production: Equipped with a multi-stage pretreatment system (sand filter → activated carbon filter → precision filter) to protect the RO membrane from fouling. The system automatically flushes the membrane every 2 hours (30-second flush) to extend its service life to 2-3 years.
Intelligent Monitoring: A 7-inch touchscreen HMI displays real-time parameters (raw water TDS, purified water TDS, water production rate, membrane pressure). It sends alerts via audible/visual signals if TDS exceeds 50 ppm or pressure is abnormal.
Modular Expansion: Each 5 m³/h unit can be connected in parallel to increase water production (e.g., 3 units for 15 m³/h). The compact design (1.5m×0.8m×1.2m per unit) saves floor space in workshops.
Applications
Fertilizer production process water: Providing purified water for dissolving chemical fertilizers (e.g., urea, ammonium phosphate) to avoid impurity precipitation affecting product quality.
Organic fertilizer cooling water: Using low-TDS water to cool hot organic fertilizer granules, preventing scale formation on cooling rollers.
Equipment cleaning water: Cleaning granulators, mixers, and packaging machines to remove fertilizer residues without leaving mineral deposits.
Laboratory water supply: Supplying high-purity water for fertilizer nutrient testing (e.g., HPLC analysis of nitrogen content) to ensure accurate results.
FAQ
Q: What is the maximum TDS of raw water the filter can handle?
A: The standard model is suitable for raw water with TDS ≤1000 ppm (e.g., tap water, well water). For high-TDS raw water (1000-5000 ppm, e.g., groundwater in arid areas), an optional nanofiltration (NF) pretreatment module is required.
Q: How often to replace the pretreatment filters?
A: The sand filter media is replaced every 6-12 months, the activated carbon every 3-6 months, and the precision filter cartridge (5 μm) every 15-30 days—depending on raw water turbidity.
Q: Can the system operate in low-temperature environments?
A: The optimal operating temperature is 5-45℃. For temperatures below 5℃ (e.g., winter workshops in cold regions), an optional water heater (electric or steam-powered) can maintain the water temperature at 10-15℃ to ensure RO membrane efficiency.
Q: Is there a wastewater recycling option?
A: Yes, an optional wastewater recycling module can treat the RO concentrate (wastewater) to TDS ≤300 ppm, which can be reused for equipment flushing or plant irrigation—reducing water waste by 40%.
