South Africa, a third-world country, is challenged by its water treatment techniques. This poses a technological, operational, and economic challenge for water treatment facilities.
South Africa is currently experiencing a difficult economic landscape. For 2024, the projected GDP growth is approximately 1.2 percent, a slight improvement from the previous year’s growth of below 1 percent.
Despite these challenges, South Africa remains a significant player in the Southern African region, which is expected to see a modest increase in growth. The population is seeing a brisk annual growth rate for 2024.
Wastewater treatment poses a significant challenge for a country grappling with both economic and growing population pressures.
So how does wastewater treatment focus its resources in this difficult environment?
The conventional technique to measure microorganisms in water, called Biochemical Oxygen Demand (BOD), is also referred to as the BOD5 measurement. It is a test that determines the amount of oxygen consumed by microorganisms while decomposing organic matter in a water sample over a 5-day incubation period at 20°C. This test is widely used as an indicator of organic pollution in water, as it measures the amount of biodegradable organic material present, reflecting the strength of wastewater or the level of pollution in a natural body of water. The BOD5 value is typically expressed in milligrams of oxygen per liter (mg/L).
