The YOUWAN method is patented concentrate technology which is developed for treating nickel in chemical nickel waste fluid and concentrate it into nickel sulfate concentrate,and can help you achieve:
• "Selective" concentrated metals
• Increase revenue
• Reduce risk
• Water recovery rate, up to 99% (the highest in the world))
• Concentration of concentrate, up to 400 g/L (the highest in the world)
• The treated water can meet the discharge wastewater standard.
• Collect wanted substances selectively from wastewater and Discharge no wanted substances in the treated water.
• The inflow concentration of raw water is up to 60 g/L for replace the wastewater process
• One drop of water can be used up to 500 times
YOUWAN method is a new generation of concentration method that combines ion exchange chromatography with water-saving method for cleaning resin.
To concentrate the substance what you wanted by the YOUWAN method, you must have “air-intake and drain step” to drain most of the wastewater and waste regenerant from the resin tower in the previous regeneration, and then use several “assistant drain step”. A small amount of water dissolves the wastewater and waste regenerant in the resin, and then discharges it with air to reduce the amount of water used to clean the resin. Then the regeneration wastewater is collected according to the concentration of the adsorbed substances, so that the rinsing water can be used in the next regeneration.
The best result is that in the process of resin regeneration, no rinsing wastewater will be discharged, only concentrated liquid will be produced.
The regeneration is done by the regenerate contains the adsorbed substances and regenerate that were collected in the previous regeneration. During the regeneration, collecting the low-concentration rinsing water to the rinsing water tank first, and then collecting the medium-concentration rinsing water to the regenerant tank, and finally collecting the highest concentration of concentrated liquid to the regenerant recovery tank.
The best result is that the concentrate capacity of the YOUWAN method can reach 1.5-2.5 times of the resin adsorption capacity (g/LR), which is approximately equivalent to the concentration of sludge.
Transform useful substances in wastewater into profit-making opportunities
Turn the concentrated liquid into the raw material of the "recycler"
Improve infrastructure and diversify revenue streams
Reduce production costs and increase competitive advantage.
Multi-purpose applications of recycle, include:
- Reuse the manufacturing process on its own, instead of purchasing raw materials
- Hand it over to recyclers, and then make products for other manufacturers
- Exchange the items obtained with manufacturers in neighboring industrial areas
Selectively concentrate the raw materials you want to reuse
Proven and commercialized technology
Fully automatic wastewater treatment process, reducing labor
Combine recycling equipment function with wastewater equipment’s function,
reducing maintenance fee Reduce waste sludge
High concentration efficiency, low energy consumption
Significantly reduce the amount of waste water and sludge
Reduce greenhouse gas emissions
Smaller carbon footprint
Reduce the development of water resources
Zero emission, zero risk
Basically, If substance is in an "ionic form" and exists in a solvent (including organic solvents), the "YOUWAN Method" can adsorb and concentrate the substance you want.

Yes, this is the most fascinating part of using YOUWAN technology, because most resins have an adsorption order, just select the appropriate resin and adsorption order, you can concentrate the ions you want. If you don't know how to choose, please contact YOUWAN.。
