WDE3 RAINWATER STORAGE TREATMENT SOLUTIONS. ERADICATION OF ALGAE, BACTERIA AND OTHER PATHOGENS. Collecting rainwater is good practice where water restrictions are in place. In areas stricken by drought and with limited available groundwater supplies, it’s of critical importance to maintain precious food crops. In sub-Saharan Africa, 90% of agriculture is rain-fed and rainwater harvesting is vital. Rainwater is not as pure as it may appear. It may be contaminated by pollutants and considered unsuitable for drinking without treatment. Harvested from roofs it can contain animal and bird faeces, plant matter, windblown dust as well as particulate from urban pollution, pesticides, inorganic ions and dissolved gases. Stored rainwater is a potential breeding ground for pathogens and is vulnerable to algae and bacterial growth which can lead to toxic conditions. Testing to determine what measures must be taken before drinking is recommended. Our WDE3 solution ensures the eradication of algae, bacteria and other pathogens found in rainwater.
