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. )
Consider HydroFlow that uses a sustained AC current to create 150 kHz frequency that neutralizes bacteria and algae through water recirculation in ponds and pipelines. This 2 minute video explains: https://www.youtube.com/watch?v=uwe2RCDt76Y
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).
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
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
Use Geomembrane or laterite clay soil instead of polythene sheet to prevent percolation through bottom of farm pond and to reduce growth of algae inside farm pond.
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
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
bonjour c'est normal , pourquoi? nothing replaces a natural Biological function of it and that it is your straw or another thing of the stones of the sand of fabric a filter has authority to thus retain to clog and thus to destroy any biological state
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.
Self-cleaning screen on suction end of pump (Plum Creek Screen)
LAKOS offers a self-cleaning stainless steel mesh screen that uses some of the filtered water to blow off accumulated algae from the screen. It is low maintenance and keeps the algae in the pond. Below is a link with more information.
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.

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.
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.
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.
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
