Irrigation and targeted nutrient supply in vegetable and fruit growing gains more and more importance in recent years. The quality of the crops, their aesthetic appearance as well as the lifespan of the irrigation system are affected by the quality of water used for irrigation.
Offered are
high quality industrial solutions
low operation cost
iron removal
boron removal
arsenic removal
reverse osmosis
container mounted system
By the application of reverse osmosis unwanted components can be removed safely and economically.

Calcium and magnesium: Plants can tolerate high levels of them, but high water hardness causes stains on leaves when water is sprayed. High hardness causes adverse effect (blockings) in the irrigation system.
Sodium: If its contentration is is lower that 69 ppm (3 mEq/L), surface irrigation does not damage plant life. In case of exceeding this value, it may cause leaf burn, alkalization of the soil. The acceptable quantity SAR (Sodium Adsorption Ratio) is lower than 3.
Chloride: If its concentration is less than 108 ppm, no adverse effect can be expected.
Iron and manganese:These substances in higher concentration (when their solubility decreases) can cause irreversible precipitation in the irrigation system. The colour of water will be yellow-brownish, and will give negative aesthetical effect to plants.
