Recently, our customer from Uzbekistan, purchased our horticultural purification reverse osmosis water treatment plant.Reverse osmosis water treatment plants can be used in a variety of applications and whenever you need water, then you probably need it.
The nutrients that plants need to grow can only be absorbed and used if they are dissolved in water. Plants have different nutrient requirements during different growth periods and the amount of each nutrient required can vary from plant to plant. Using tap water as a solvent to prepare nutrient solutions can be influenced by other inorganic salts in the tap water, which in turn can affect the actual results to be achieved. The use of pure water as a solvent greatly reduces the interference of other ions and meets the horticultural requirements to a great extent.
The various salts in tap water can precipitate from the surface of plant leaves and flowers due to the evaporation of water, forming watermarks and affecting the ornamental effect. Tap water contains various salts and has a high conductivity. In some areas, the conductivity of gardening water can be as high as 700us/cm or more, so when tap water is used for potted flowers, the salinisation of the soil will become heavier and heavier, affecting the growth of plants and being extremely detrimental to the growth of potted flowers and trees. This is why horticultural water must be desalinated.
The main methods of water desalination are electrodialysis, sodium filtration, ion exchange and reverse osmosis, but electrodialysis can only achieve a desalination rate of around 60%, which is difficult to ensure the requirements of gardening water. Although the desalination rate of sodium filtration is around 80%, sodium filtration is selective in the removal of salts in the water. The removal rate of calcium and magnesium salts is high, up to 95% or more, but the removal rate of salts with a small ionic radius, such as sodium salts, is very low. Both ion exchange and reverse osmosis can be used to obtain the desired desalination rate. The ion-exchange resin must be regenerated with acid and alkali after saturation, so there is acid and alkali waste discharge, and there is hydrochloric acid and sodium hydroxide storage on site, which can bring secondary pollution and potentially endanger seedlings if not managed properly. Pure water, on the other hand, has a very low salt content and can prevent salinisation of the soil. The use of pure water in horticulture maximises the use of inorganic salts.
Horticultural purification water treatment plants (industrial reverse osmosis)
A. Conductivity below 100us/cm,.
B. Desalination rate shall be stabilized at 85% or more.
C. Automatic operation party for the type, the daily operation process only pre-treatment backwashing and water softener regeneration requires simple manual operation, management is very convenient, the water quality is also stable.
Pure water contains low salt content, pure water equipment desalination rate is stable, desalination rate of up to 98% or more. The use of pure water for filling can reduce the salinity of the soil, and the use of pure water as a solvent for pharmaceuticals can reduce the interference of ions and improve the effective utilisation of pharmaceuticals. Reduces pests and diseases in flowering greenery. Improves the ornamental value of flowering and foliage plants.
