Stabilized hydrogen peroxide (such as Huwa-San TR-50) is one of the substances that is added to irrigation water. This is dosed during the irrigation to keep drip hoses or irrigation pipes clean. In addition, it also kills bacteria, fungi and viruses in water streams.

Incorrect application of stabilized hydrogen peroxide comes with risks. Think of damage to roots due to too high a dosage. For example, in order to prevent the release of dirt or burning of roots, it is extremely important to dose such substances as safely and in a controlled manner as possible at the desired and set dosage.

With a dosing pump you can avoid these risks and ensure the optimal effect of stabilized hydrogen peroxide. Use a dosing pump that is controlled by a pulse output of a liter counter, so that the dosing is always adjusted to the current flow. As a result, the dosage is always the same in proportion to the realized water flow and the risk of damage to the crop due to an overdose is nil.

When selecting the correct dosing pump, take into account the system flow of the water system. The pump must deliver sufficient capacity, but must also leave some space to be able to give a shock dose during crop rotation, for example, to thoroughly clean and spray the water system. In addition, it is important that the type of dosing pump is equipped with Viton (FPM) seals and with an automatic vent for degassing liquids such as water peroxide.

When a dosing pump is "too big", this has a disadvantageous effect. The stroke frequency will then be low, with the result that the interval between the dosing strokes is long. This makes the distribution in the water less even.

Within our range you will find all components to be able to install a dosing unit that can deliver the desired liquid in even and very accurate quantities (ppm/ml/m³) with every watering. This set contains a:

• Magdos LD dosing pump fitted with Viton (FPM) seals and equipped with automatic deaeration
• Injection point to be mounted on the discharge pipe, with accompanying:
• Flow sensor
• Switch box which makes the system applicable to any desired pipe diameter

The set can be provided with a release signal in two ways, so that dosing can be prevented in case of false flow. In this way, the dosing pump is only enabled when the irrigation system pump is running. The dosing pump on the suction lance also has a:

• dosing tank minimum pre-alarm (indication when it is almost empty).
• dosing tank empty main alarm (indication when it is empty). Automatically blocks the dosage.

How to maintain the filters of the watering system?
Regular maintenance on the filters of the watering system is important for the preservation. The crop rotation is the perfect time to maintain the filters of the watering systems. 

Which water purification technologies are available for horticulture?
Water purification is an important condition for a good cultivation. There are different water purifications technologies that you can use.

How to limit the travel time of water?
When you apply changes to the irrigation water, or when you add an agent to the irrigation, it will take some time before this water reaches the plant. This is called the travel time of water.
