BIZ will deal with the biological (biological = to living organisms; bio = of or relating to life) treatment of domestic effluent (liquid waste or sewage). Those of us with daily access to clean and efficiently flushing toilets don't think twice about the hazards of unsafe sanitation, which include diseases like cholera and dysentery, and environmental pollution. Cholera outbreaks tend to receive widespread media attention and speedy, crisis-management responses...........Less talked about but just as deadly is acute diarrhoea, which is a direct consequence of poor water and sanitation provision. Diarrhoea kills more than 50 000 African children every year and affects millions more. HIV and Aids sufferers with compromised immunity are particularly vulnerable to diseases related to poor sanitation.BIZ BIO Treats all of the above and more. Friendly to the Environment.
