    what is dripper?

    Irrigation dropper or dripper is one of the main equipment used in the agricultural industry, which is widely used in drip irrigation systems. Factors such as soil conditions, the amount of water required by the crop, and the quality of water used play a key role in the design of the dripper.

    Below we will look at the types of agricultural emitters and the price of irrigation emitters and explain the important points when buying and selling drippers.

    How an irrigation dripper works:

    The way the dripper works is by installing a drip irrigation on a pre-designed spacer with a small size (soft hose). The water is discharged into the dripper after being pushed into the emitter at approximately 1 time pressure, discharged continuously without pressure at a flow rate of about 1 to 24 liters per hour.

    The best type of dripper:

    The best drippers can be characterized by a unique and creative design, high precision in molding, the use of quality raw materials and quality control experiments that are key and effective factors in producing an irrigation dripper.

    Advantages of drip irrigation:

    1- The drip irrigation system has reduced itself to a unique system compared to other irrigation methods by reducing water consumption and reducing manpower costs.

    2- In drip irrigation, due to the lack of excess water in the soil and the lack of weeds, cultivation is easier.

    3- Due to the constant humidity in the drip irrigation system, the salts in the solution remain diluted, so water can be used with greater salinity than other irrigation methods.

    4- Increase in products.


    Types of dripper:

    1- Dripper with fixed or adjustable capacity.

    2- Normal dripper.



    Types of irrigation drippers’ price:

    The prices of different emitters vary depending on the type, brand and capacity. For example, at present, Iranian drippers have prices between 450 and 500 Tomans and foreign drippers have prices between 750 and 950 Tomans.

    The obstruction of irrigation dripper:

    Drip obstruction is an important problem that can reduce the uniformity of distribution, the average water output of the dripper and, ultimately, the irrigation efficiency and increase the volume of plant growth needed.

    Dripper obstruction will waste water, energy and loss of trust among users. Therefore, tackling emitter clogging is a common way to optimize the water resources and increase the efficiency of the irrigation system.

    The reasons for drippers’ obstruction:

    Suspended materials in the water.

    Chemical sediments.

    Growth of microbial organisms.

    The following table shows the differences between the two methods of irrigation with dripper (topical) and sprinkler (rain).

    The dripper drops water at low pressure.

    The sprinkler drops the water with high pressure.

    The dripper drops the water with a low flow rate.

    The sprinkler drops the water with a high flow rate.

    The dropper disperses water in a confined area.

    The sprinkler distributes water on a large surface.


    Types of irrigation dripper:

    The following two categories can be achieved by subtracting pressure and energy from the dropper criterion.

    The so-called aperture drippers having a cross-sectional area of 0.2 to 0.35mm2.

    Long-distance drippers with cross-sectional area of 1 to 4.5mm2.

    Irrigation drippers can also be placed in another subdivision by type of installation:

    On-line dripper assembled using a punch on the pipe wall.

    An in-line dripper will make sure the pipe is cut for installation.

    The irrigation drippers’ obstruction:

    Obstruction is an important problem that can reduce the uniformity of distribution, average drip water output and, ultimately, irrigation efficiency, increase the volume of plant growth needed, and ultimately lead to wasted water and energy costs and users' distrust. Therefore, tackling these drippers is a way to efficiently utilize the water resources and increase the efficiency of the irrigation system.

    The reasons for obstruction in irrigation systems:

    Suspended chemicals in the irrigation water:

    Irrigation water suspensions include sand, silt, vegetable, algae, fish, etc. Usually particles larger than one-tenth of the water through the nozzle or dropper must be filtered. The degree of filtration is described by the mesh size. (Number of holes per inch) and for filtration, 200 mesh is recommended. In each drip irrigation system, it is necessary to remove suspended particles from two sets of filters from the three sets of filters available.

    Available filters include hydro cyclone filters to remove silt and fine sand particles in water (its performance is based on centrifugal force).

    Sand filters for removing algae and other suspended matter in surface water and water storage pools, and mesh or disk filters for final removal of residual suspended particles such as clay, silt and sand in water.

    Note: It should be noted that only secondary sand filters and cyclone filters should be used when pumping directly when secondary pumping is possible if the silt and fine sand particles in the water in the basin are fully settled.

    Chemical sediments:

    The roots of chemical sediments are due to the lack of water quality, injection of fertilizer, etc. In groundwater there is a problem of calcium carbonate deposition (white) and iron deposition problem (reddish brown).

    The formation of calcium deposits is caused by changes in water pH, warming, evaporation and chemical reactions of some types of fertilizers. In general, carbonate clogging occurs due to the concentration of more than 122 mg / L bicarbonate in water and pH above 7.5.

    Growth of microbial organisms:

    Algae, bacteria, and fungi grow in the pipelines and cause clogging, and the solution is to add chlorine to the irrigation water.

    Acid Washing Drip Irrigation System:

    A solvent such as acid is used as a substance to prevent the accumulation of all kinds of hydroxide, salts, carbonates and phosphates. The acid concentration (concentration) added to the irrigation depends on the acid content and type of acid.

    Acids should be free of insoluble impurities such as gypsum, oil and so on. The following table shows the recommended concentrations of different acids.

    The advantages of drip irrigation:

    This system is an important advantage over other irrigation methods due to reduced water consumption and reduced manpower costs.

    Weeds do not grow as water does not reach the surface of the soil, making farming easier.

    Due to the constant moisture in the drip irrigation method, the salts in the solution are kept diluted, so water can be used with greater salinity than other irrigation methods.

    Increase in the products.

    Israel's drip irrigation system is one of the most successful experiments in the world. A land like Iran in a Middle East that has experienced unprecedented drought for the past 900 years. Israel saw agricultural production as one of its economic foundations in the 60 percent of the desert.

    To achieve this goal, in addition to establishing a desalination plant, they have invented many innovations and innovations in advanced salt treatment and drip irrigation. With 86 percent of the water reused, it now holds the first position in the world in water recycling.

    The price of drip irrigation type:

    The price of different drippers varies according to their type, brand and emitter capacity. For example, the current Iranian drippers are priced between 450 and 500 Tomans and foreign drippers are priced between 750 and 950 Tomans. Iranian and foreign brands of drippers include Iran Drip Dropper, Irritec Dropper, US Netafim Dropper, Israeli Dripper and Eurodrip Dropper.
