Product Classification



Plants’ requirements for nutrients vary in its different growing periods. Meanwhile, leafing and flowering plants have various requirements for various nutrient elements. Nutrient solution prepared with tap water may affected by the inorganic salts in the latter and thus affect the actual effect. However, taking pure water as solvent can greatly reduce the interruption of other ions and meet the garden requirements to the maximum extent.
Soils occupy small proportion in potted flowers while tap water contains various salts. As the evaporated moisture is pure water, therefore, salinization of soil will be increasingly severe if tap water is used for irrigation and thus it will affect the growth of plants. The extremely low salt content in pure water can prevent soil salinization. Pure water irrigation greatly improves the utilization of inorganic salt to achieve the best anticipated landscape effect.  
Conductivity of water for gardening should be lower than 100us/cm. However, most of garden spots are located at suburbs, and the water for use usually comes from simply processed tap water or deep well water with high conductivity as high as 700us/cm in some areas which is extremely disadvantageous to the growth of plants. Therefore, water for gardening must be desalted and the salt removing rate should be stable above 85%.
Desalination of water is usually realized through electrodialysis, sodium filtration, ion exchange and reverse osmosis. Salt removing rate of electrodialysis is usually at about 60% which can hardly satisfy the demand of water for gardening. Though with a salt removing rate at about 80%, sodium filtration is selective to the desalination, removing calcium and magnesium salt as high as 95%, while removing fewer salts with smaller ion radius like sodium salt. Thus, for inwelling areas and brackish water areas with higher chlorine content, sodium filtration is not ideal for desalination. Reverse osmosis is a proper choice. Automatically operated, RO requires only backwash for pretreatment and softener regeneration manually, rendering convenient management. Also the conductivity of the yield is lower than 100us/cm.
