Schmutzdecke, the biofilm formed on top of sand bed in household slow filters (HSSF) is a key factor for filters’ high efficiency removing particles and microorganisms from water. This paper aims to investigate extracellular polymeric substances composition (carbohydrates proteins), biomass, dissolved oxygen, microbial community two types HSSFs identify correlation between them their efficiency. A continuous- an intermittent-HSSF (C-HSSF I-HSSF) were studied treat river water 48 days. Their...
Household Water Treatment and Safe Storage (HWTS) are recommended to supply the demand for drinking water in communities without conventional systems. However, there is a lack of long-term laboratory studies regarding such technologies. We evaluated contributions each step multi-barrier system with pretreatment (sedimentation fabric filtration), filtration Slow Sand Filters (HSSFs) disinfection (sodium hypochlorite) treating surface more than 14 consecutive months. Removal turbidity, colour,...
This study aimed to evaluate the efficiency of four household slow sand filter (HSSF) models for removal microorganisms from river water throughout development their biological layers (schmutzdecke). Two were designed be operated continuously (HSSF-CC and HSSF-CT) two intermittently (HSSF-ID HSSF-IF). Filters fed daily with 48 L pre-treated (24 h sedimentation followed by filtration through a non-woven synthetic blanket). Water samples quantified coliform group bacteria analysed bright field...
