UV and chlorine Water Disinfection

Reusing untreated drainage water can contaminate the irrigation system and cause disease to other crops.

Many greenhouses use a closed cultivation system to reduce soil and groundwater contamination (from fertilisers and crop protection agents).

This system allows the reuse of water that is drained and not absorbed by the roots. However, to do so, you need to install a drain water disinfection system that allows you to purify water and reduce the risk of disease transmission.

Water disinfection methods

At Novagric you can find different treatments for water disinfection:

Ultraviolet (UV) disinfection

It uses ultraviolet radiation (UV-C) to disinfect the water.

It is very effective and allows you to:

  • Reusing soilless crop drainage

  • Reuse of wastewater from human and industrial processes

  • Prevent the presence of disease-transmitting pathogens such as bacteria and viruses in irrigation water.

  • Sanitary suitability of water for washing fruit and vegetables.

  • Sanitary use

Its use is recommended for the reuse of drainage water and drinking water purification for human consumption.

Components of an Ultraviolet treatment system

  • Low velocity sand bed filtration.

  • Chamber with low-pressure UV radiation lamp.

  • UV radiation intensity sensor.

  • Lamp cleaning system with acid dosing equipment.

  • Circuit for production control and cleaning of the UV lamp.

Advantages of UV disinfection

  • Maximum Disinfection Effectiveness and protection of your crop: Ultraviolet (UV) radiation inactivates pathogenic microorganisms in the water, such as bacteria and viruses, without the need for chemicals.

  • Ease of Use: UV systems are easy to operate and require little maintenance, integrating easily into existing irrigation systems.

  • Saves water, fertiliser and energy: Although the initial investment may be higher, operating costs are low in the long run due to low energy and maintenance consumption.

Water disinfection with chlorine

Chlorination of water for disinfection is one of the most widely used methods because it is simple and economical.

It consists of disinfecting water with chlorine for clean water use. With a chlorimetric monitoring system, you can easily determine the presence of free chlorine in the water.

Sand Filtration Equipment

Before disinfecting the water with UV you need to filter out the suspended solids to avoid shadows in the reactor. This ensures that all organic matter is removed.

For this purpose a filter medium with silica sand and anthracite (inside polyamide tanks) is used. With a filtration degree of 30 microns and an autonomous pressurised backwashing system, timed control or differential pressure.

With sand filtration equipment and UV disinfection you get safe water reuse.
