Water Treatment

Maina Soko, a military hospital located in Lusaka Zambia, required a packaged water treatment solution to treat the water fed into the hospital from the municipal line as well as provide pre-treatment of their borehole water to suitable levels for feeding into a reverse osmosis plant 

 

Davis & Shirtliff therefore engaged to design two water treatment plants each of similar capacity 40m3/hr which included:- 

  1. Multicyclone centrifuge filters for the removal of larger suspended particles of 40 – 80 micron to increase the filtration cycle of the Ultrafiltration plant 
  2. Ultrafiltration treatment system c/w robust DUPONT UF modules with a recovery of 97.7% For ease of transportation and handling the plant was designed using 12No. IP-51 modules achieving a flux of 70LMH and all the equipment fitted into a 20ft container 

The Ultrafiltration system is based on size exclusion and is effective in the removal of all suspended material to the size of 0.02mic. The system comes complete with post – chlorine disinfection to provide for residual disinfection of the treated water and the hospital now has a consistent source of clean potable water that meets WHO and local drinking standards
