How do you tackle oxadixyl contamination?
asked 28 June 2016 asked by AP ( points)
Hello, For neophytes like me, a basic Internet search reveals that oxadixyl is a systemic fungicide used for a variety of food crops susceptible to mildew and certain parasites from the oomycetes family. Uses: agriculture and viticulture
This phytosanitary product can probably be adsorbed using activated carbon. You would need to know the concentrations in the water. Some phytosanitary products cannot be adsorbed with granular activated carbon but can be precipitated using coagulants such as iron or aluminum salts. This is followed by addition of an anionic flocculant and then decantation. You should specify the issues involved: what the water is used for, what flow or volume needs to be treated, features of the contaminated water, etc.
Hello, Oxadixyl is adsorbed using activated carbon (powder or granules). But you need a contact time of more than 14 min because this pesticide is highly water-soluble.
Hello, This fungicide has been banned in France for more than 10 years! Due to its physico-chemical characteristics and particular partition (distribution) coefficient, it must be adsorbed onto activated carbon in granular or powder form.
Activated carbon adsorbs oxadixyl. A study conducted by the International Research Center on Water and the Environment (CIRSEE) indicated that the nature of the water itself determined the performance of the activated carbon. High levels of dissolved organic carbon will reduce the service life of the filter. Contact time has nothing to do with performance.
