Water Purification Start-Up Kusini Water Aims To Supply Clean And Disease Free Water
Water Purification Start-Up Kusini Water Aims To Supply Clean And Disease Free Water. Kusini Water is a social enterprise that builds water treatment systems from nanotechnology and macadamia nut shells. Its systems bring clean, safe drinking water to people in rural, peri-urban and informal settlements throughout the African continent.
Kusini systems use locally sourced macadamia nut shells that are off-waste, use no electricity and generate zero waste. All its water systems comply with the South African national drinking water Standard. The filter removes 99.9% of disease causing bacteria & parasites from any water source. The Filter is comprised of a mechanical nano-filter with an activated carbon block in the centre. That means it physically separates particles from the water by trapping them inside the membrane. Because its filter uses a mechanical filtration process, the Filter remains safe throughout the entire life of the filter.
The company’s products use two-stage filtration process; In addition to the nano-fiber membrane, an active carbon block made from locally sourced macadamia nut shells is used to absorb chemicals like chlorine and pesticides. All its products use a nano-fiber membrane. These membranes have 0,01micron pores that trap contaminants on one side and release clean water on the other end. The company’s membrane uses the latest technology in membrane production with minimum chemicals. All its filtration systems are monitored and controlled using a smart water meter that is IOT enabled. This allows the company to know the state of each site so it can keep water flowing at all times. This device allows it to monitor and operate its systems remotely and carry out maintenance as needed.
E-coli, bacteria and things such as dissolved solids are bigger than the pores in the filter. Clean Water is able to pass through, but contaminants larger than 0.01 microns remain trapped, leaving water clean and disease free. Unlike current best practice of Reverse Osmosis the company’s system doesn’t have any waste discharge. It shouldn’t cause further strain on constrained resources such as energy.
