Abstract

A method of preventing the formation of microbiological deposits in the water delivery systems of micro-irrigation systems which have in addition to water delivery systems, a water filtration system, a pump and a water distribution system. This method comprises cleaning the micro-irrigation system to remove existing microbiological deposits thereby providing a clean distribution and delivery system, and then continuously treating the water fed to the delivery system with a few ppm of glutaraldehyde to maintain cleanliness. The invention is particularly effective in controlling microbiological deposits which are either slimes or algae or mixtures thereof.

Claims

exact text as granted — not AI-modified
We claim:  
     
         1 . A method of preventing the formation of microbiological deposits in the water delivery systems of micro-irrigation systems which have in addition to a water delivery system, a water filtration system, a pump and a water distribution system which comprises the steps of: 
 (a) cleaning the micro-irrigation system to remove existing microbiological deposits thereby providing a clean distribution and delivery system, and then;    (b) treating the water fed to the delivery system with a few ppm of glutaraldehyde.    
     
     
         2 . The method of  claim 1  where the glutaraldehyde is continuously fed to the delivery system.  
     
     
         3 . The method of  claim 2  where the glutaraldehyde is added after the water filtration system.  
     
     
         4 . The method of  claim 1  where the microbiological deposits are slimes.  
     
     
         5 . The method of  claim 4  where the slimes contain iron and manganese bacteria.  
     
     
         6 . The method of  claim 1  where the microbiological deposits are algae.  
     
     
         7 . The method of  claim 1  where the microbiological deposits are a mixture of slimes and algae.  
     
     
         8 . The method of  claim 7  where the mixture of slimes and algae contain iron and manganese bacteria.  
     
     
         9 . The method of  claim 1  where the glutaraldehyde is fed at a dosage ranging between 0.1-10 ppm.  
     
     
         10 . The method of  claim 1  where the glutaraldehyde is fed at a dosage ranging between 0.5-5 ppm.  
     
     
         11 . The method of  claim 1  where the glutaraldehyde is fed at a dosage ranging between 1-5 ppm.
