After one year of implementing the pilot study, the Institute of Biochemistry and professional documents (Ministry of Public Security) said it has succeeded in treating domestic wastewater by high-load biological module technology.

Water filter modules are made of steel and shaped like cargo containers. Inside the module are filter materials, sewage pumps and air blowers. Accordingly, wastewater is continuously transported to the container and mixed with air from the air blower to filter. The waste water will then flow to the sediment compartment and be disinfected before being discharged into the environment.

Use rainwater solution in Africa

According to a report by the United Nations Environment Program (UNEP), rainwater collection and storage is an effective low-cost measure to deal with water shortages in Africa.

Scientists have found that rains in some countries in the continent are enough to provide six or seven times more water than current needs and can prevent for future droughts. hybrid A pilot project has been applied in the Maasai community in Kenya and improved water supply problems, helping people to dive into the rivers daily.
