Treatment for irrigation water

Published on by in Technology

I am an agriculturist and growing mainly cotton in my family farm. I use drip irrigation system for the irrigating the crop. We have a small farm pond, covered with polythene sheet to reduce the percolation of water. My problem is the constant growth of algae in water which creates problem in irrigation system. I am interested in exploring some new and cheap treatment methods for reducing this algae from the irrigation water so that drip doesn't have any problem. ( We have used barley straw to control the algae but it still there is formation of Algae in the pond. )

  2. Algae and biofilm control

    There is a relatively new product which is a solar powered algae and biofilm solution which i have witnessed working in South Africa. The product costs around 42000Rand it also reduces ecoli counts to safer levels. The product called biosprite is made by a company called Water Enrichment Treatment Solutions (W.E.T.S).

  3. Algae removal

    Either remove the nutrients that feed the algae, nitrogen and phosphorous or we have a biopolymer product that when liquified will collect and drop out the algae and you can dry it and use it for fertilizer. We ship from USA

  4. Dear Mazina, I am not that expert or irrigation water, but first you reduce the amount of suspended solids in the water to avoid clogging of your drip irrigation systems. Then you to reduce dissolved solid in hard waters by decantation to avoid clogging your metal or plastic conveyor pipes. You need to well know the water quality of waters used in irrigation. Said

  5. Covering the pond (to reduce sunlight contact) and re-circulation of the pond water should make your life easy.

  7. Floating reed beds can provide a good and cost effective solution as they will cover some of the surface area and prevent direct sunlight; however need to make sure that there is still sufficient free (non-covered) area for the atmospheric oxygen to access water in the pond. You can also harvest these reeds (need to select species that are usable). Similar project have been done in SE Asia and Northern and Western Australia with good results. Selection of the plants and area balance are two major keys to success here. Good Luck with your project! Regards, Iouri

  8. Im against the use of petroliem product like polimer pipe or plastic

    First I will suggest to store all kind of water, the plastic  is poision put off the plastic cover and cover it with date leaves made sheet, Instead of a drip old water Irregation open system made of slab construtiion is better made of concreate to distribute eqal level of water focus on land leveling instead of drip this is my honest answer may be many of you dont like it, Distribute it from hight it will get more energet storing all kind of water then fileter it with normal filtration system in market but steralize the filter and in last use Neem leaves or Plant neam trees around pound area its good or use little neam Oil

    Kind Regards to all ;

  10. a natural special lavastone powder is helpfull

    Hey Mazina, 

    a natural special lavastonepowder is very usefull. It's also used for Biotopes and Seas. See www.baleari.de

  12. Protection of Ponds against Excessive Algae Growth

    Usually algae can be controlled with spreading copper sulfate in the pond - however, it is not known what crops you have and how would copper sulfate impact them.

    Alternative treatment is to cover the reservoir with small plastic balls that float on the surface and prevent sunlight from reaching the pond.  There are companies specialized in making such balls (usually of diameter of 5 to 6 cm each) but you could use any other balls that are not transparent. 

  14. Mazina KM My suggestions are similar to many others. in the first instance consider using black sheeting to cover your pond to reduce the amount of sunlight on the water. Secondly, install a pumping system that will recirculate the water. this need not be expensive, a small high volume, low pressure pump the could run for a few hours per day would work and with careful placement of the outflow there should not be too much disturbance to create sediment that would cause blockages to your irrigation tape.

  15. My

    It should be as we offer you avoid exposure to strong light and it will also avoid letting water stagnate (circulating water). Control of data quality and quantity is important.

  16. Side Tank

    As considering the views  of the other respected person ,I come on to conclusion that instead of doing treatment for the algae growth in pond  construct the side tank of 3 or 5 cum . And from the tank give supply to your irrigation system. the water comes to tank through a membrane filter [  use economically  available local membrane]   from pond whenever you required the system to activate. After every 2-3 day cycle clean the filter of tank. This solution will definitely help you to come out  from the problem. Also in the storage pond use aeration treatment  in a month cycle to avoid the development of algal plants. 

  18. Know by testing the Nitrogen content of your irrigation water (Nitrogen Spectrum tests) which include the Ammonia Nitrogen as (N) test that will indicate the amount of Anhydrous Ammonia fertilizer runoff recaptured in your irrigation water. So don't add Chlorine, for the Biological Nitrogen runoff in the irrigation water to lessen the algae growth, as it reacts with the Anhydrous Ammonia, that creates a larger issue.

  20. Hi, I would recommend 2 options:- 1. a small paddle aerator, this will oxygenate the water and also disrupt the eplimnion. The algae require this warm upper layer to photosynthesize, and then drop to the bottom of the pond overnight to assimilate nutrients. Disrupting the layers disrupts this growth cycle. 2. ultrasound is also very effective. LG do one that runs on solar power so running costs are virtually nil. http://www.lgsonic.com/ Hope this helps

  21. We also had the same problem once but not any more. We have 3 pools sizing 200 X 600 ft and 6 feet deep. Soil is highly porous. Some years back we did use poly ethylene sheets but they were always destroyed by the weeds growing through them. So we resorted to clay plaster and we found it doing the job. To our algal problem, we reared fish and its doing well and we do not need any eco friendly enzymes:)

  22. It appears that your algae is growing due to lack of oxygen in the water. A simple fix would be to install a pump hooked to a compressor in the bottom of your pond to get your water circulating. I had a similar situation with a shallow marine and installed a air line to a pump in our marina and it corrected the problem.

  24. Small ponds have always an issue for Algae. The main reason for algal development is sunlight and stagnant water. To avoid the growth there are enzymes available in the market for which the algae is nutrition. Further you need airation, have a floating fountain in you pond. this will help you avoid water becoming stagnant and there are much less chances of algal growth than. Further more to both of the above, you can have a floating garden in your pond which behaves as a ecosystem and the algae will be its nutrient. This is a very effective technique but you need to be very specific in selecting the floating garden plants. But to go for any of the above solution, your pond data as in quantity, quality of water, region, etc are very imp factors.

  28. I agree with George Laszlo and believe that in fact we need two sets of data. First the size parameters comprising the depth and second the chemical parameters, mainly pH, dissolved oxygen and redox. If it were possible to know the kind of algea you have that would help. Algae develop when they find nutriments to do so and when the chemical parameters build for them a nice environment. It is often difficult to eradicate them but it can be done.

  29. Treatment of irrgation water

    There is a possibility to reduce Algae with special enzimes, eco friendly.

    Need to know:

    size of your reservoir or pond

    source of water

    quantity of water needed par day

    way of transferring the water.

    area - quantity of rainfall per annum

  31. try using coptrol?
