Crude prefiltration with sieve bend filter

In some horticultural growing systems applying recirculation, large volumes of drainwater are produced. Particles and fibers flush with the drain water from for example tray- and container fields in strawberry and ornamental horticulture as these crops are still grown on peat or coir. Before collecting the water in a filthy drain silo it is necessary to remove […]

Removing particles with paper band filtration

A prior filtration is required especially when disinfection is based on the light transmission (UV) or filtration (ultrafiltration or slow sand filtration). Prior filtration removes floating particles to prevent a continuous series of self-cleaning cycles in ultrafiltration. A paper band filtration is one of the possibilities to install before a disinfection unit within a recirculated […]

Agrozone emission free fabric filter

When reusing drain water, cleanliness is the key. During the water giving period, the fertilized water can pick up many different sorts of contaminants (dirt, debris, algae, bacteria, etc.). Especially the larger dirt and debris can clog up the feeding tubes and drippers, which can cause plants to die. Agrozone has created an emission free […]

Slow and rapid sand filtration systems

The filtration through sand is achieved by mechanical, physical and biological principles. The share of each of these processes during filtration depends on the flow rate of water in the filter and the presence of microorganisms. Due to the construction and water flow speed sand filters are divided into two basic groups: slow and rapid. […]

Removal of iron from irrigation water

In ground water iron is usually present in reduced form, but as soon as the water is pumped up for irrigation, partial oxidation occurs. This changes the iron form to ferric ion (Fe3+) which is insoluble. Practically any water that contains concentrations higher than 0.5 ppm of iron cannot be directly used in drip irrigation […]
