Possibility of using membrane technology
for dewatering sludge
from water treatment plants
Abstract: The article discusses the composition of the sludge and its main properties that affect the dehydration process, and provides information on the applied mechanical methods of dehydration and their disadvantages. As an alternative solution, the use of membrane technologies involving the use of hollow fiber filters is proposed. To justify the possibility of using membrane technologies, experimental studies are carried out to determine the specific resistance of sludge from water treatment plants. The sediment untreated with reagents and the sediment conditioned by flocculants were examined. The obtained indicators were compared with the specific resistance of sewage sludge, the separation of water from which was implemented on ultrafiltration membranes. The research results showed the feasibility of further research on the use of membrane technologies for the treatment of sludge from water treatment plants.Keywords: sludge from water treatment plants, mechanical dewatering, ultrafiltration, hollow fiber membranes.
