Abstract:

Stormwater has become an issue of concern in urban centers. The transport of pollutants (oils, organic liquids, fertilizers, nutrients, and heavy metals as Cd, Cu, Pb) by stormwater runoff over impermeable surfaces (parking lots, roadways, and so forth) can carry a wide range of contaminants into the surface water, groundwater and soils and can affect the public health and the environment. The use of stormwater in non-drinking applications could be an interesting way of addressing these large volumes of water. Rainwater has become an important resource, not only in low-volume storage areas, but also in areas where the reduction of treated water consumption by local supply is desirable. Rainwater harvesting usually uses roof as catchment surface, but the ground offers a larger area to harvest water. Microfiltration (MF) and ultrafiltration (UF) are used to treat industrial wastewater and process water. MF removes particulates and bacteria. UF can remove suspended and colloidal solids, macromolecules, bacteria, and viruses. Thus, both membrane processes have been used to treat rainwater catches on rooftops and surface water on a limited scale but with promising results; but the question is: Are MF and UF able to produce water with required quality from stormwater? This study evaluates stormwater management for use in non-potable activities and pollution control by MF and UF. Stormwater was sampled in a parking lot. The permeate flux and removal rates of both membranes were evaluated in continuous operation tests. Permeate quality was compared to American, Australian, Spanish, and Brazilian guidelines. Both MF and UF membranes allow the adjustment of stormwater quality for toilet flushing and fire protection, and they have good performance in controlling pollution. UF has a better operation and removal performance and might be complementary with best management practices to obtain an overall better efficiency. Recent Publications 1.

Biography :

Vandre Barbosa Briao is Food Engineering and PhD in Chemical Engineering in Membrane Separation Processes. As an Engineer, he was the operator of a RO system for water desalination in a dairy industry. Professor at The University of Passo Fundo since 2000, he has researched MF/UF/NF/RO in food and water/wastewater applications. His goal has been the reuse of water and his research has been focused on the post-treatment of water/wastewater with hybrid systems by coagulation-electrocoagulation-adsorption coupled with membrane separation.
