Ultrafiltration (UF) has been proven to be very effective in the treatment of water for the removal of particles, colloids and microorganisms. However, household application of UF is limited due to membrane fouling which results in complex and maintenance-intensive UF systems. In gravity-driven membrane disinfection (GDMD) technology, a stable membrane flux of 4-10 L.h-1m-2 is observed during ultrafiltration without any back flushing, chemical cleaning or an external energy supply for over 24 months, while operated at relatively low pressures (40-65 cm of water column). This novel approach to operate UF systems at stable flux conditions can be considered an important breakthrough in membrane technology, as it allows development of a robust, maintenance-free, low-cost and user-friendly household water treatment system, which has a great potential for implementation.

This paper discusses the proper management and reuse of sludge generated during the treatment of arsenic contaminated water. It investigates the suitability of sludge in making brick. Results of different tests indicate the sludge proportion is the key factor for determining the quality of ornamental bricks/tiles. The study showed that arsenic contaminated sludge could be used safely up to a rate of 4% for making ornamental bricks.
