Water means life; healthy water means your crops will grow. This
has a direct effect on the financial health of your company. In an
environment where healthy growth - of your crop and your company -
takes centre stage, it is important that the (various) water flows
are optimally controlled, and that the correct quantities of
fertilisers are administered at the same time.
Priva supplies automated watering systems that allow you to
efficiently dose high-quality irrigation water and to recirculate
Pre-treatment: good quality and safe irrigation
Responsible and economical water management starts with the
correct pre-treatment of the water.
HD-UV disinfection is a very reliable water disinfection method:
it uses little energy, is safe for the environment and is
low-maintenance. Moreover, it prevents the spread of pathogens.
If the pH is too high or too low the plant cannot extract the
fertilisers from the water. Priva's watering system allows you to
fine tune the bicarbonate content so that a stable pH is achieved.
The EC pre-mixing allows you to reuse the drain water to the
greatest possible extent; this is mixed with the necessary ratio of
fresh water before the fertilisers are added.
Fertigation: supply and demand
You want to be able to administer the correct quantities of
nutrients to achieve growth. Whatever the needs of your crops, the
fertigation must be flexible and straightforward, because you want
to use sophisticated dosing of liquid and solid fertilisers. Priva
controls this with stable EC and pH; at the correct pH the plants
absorb the fertilisers efficiently, and a stable EC ensures better
growth in the glasshouse and a longer shelf-life in the supply
With Priva's sophisticated watering systems you can even have
the plant itself determine the time at which watering takes place:
the result, a healthy root system with a higher yield.
Essentially, watering that is tuned to the circumstances, the
state of the crop and the type of substrate.
Would you like to save water by recirculating longer and still
grow an even healthier crop? Save on fertilisers at the same time?
The Priva systems disinfect the drain water. This is even more
effective using a combination of HD-UV and oxidation; growth
inhibitors and other harmful substances are broken down more
Priva's water management system allows you to create a
closed-loop system for healthy growth.
Naturally, this system can be expanded with other automated
Priva systems. Examples of this are climate control, process
management, crop and harvest registration and analysis, labour
registration and analysis and management information.
