公司：Stormwater Filtration Bags for BMP pretreatment 国家：** 联系人：** 地址： This is an inquiry message about Stormwater Filtration Bags for BMP pretreatment in the 108th China Canton Fair. (这是一条买家关于"Stormwater Filtration Bags for BMP pretreatment"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) Stormwater Filtration Bags for BMP pretreatment Re: Filter Bags for Sediment Trap Application in Lake Tahoe Basin BMP retrofit program In the Lake Tahoe Basin, an ordinance exists that requires every owner of developed land (approximately 30,000 homes) to infiltrate stormwater on site. We are the Natural Resources Conservation Service, a federal agency working here in the Lake Tahoe Basin providing design assistance to homeowners faced with meeting the ordinance. My task as the civil engineer is to design a filter that is replaceable to prevent the void space in underground infiltration galleries from clogging or filling up with sediment. Your filter bags may just be the product that enables a one step process of pre-filtering stormwater, collecting, and disposing of the sediment. Requirements for the bag may include the criteria summarized below. The challenge of designing these systems has been to get adequate flow rate so that the design storm is treated without bypassing. I put together a draft of the specifications below. As engineer for the field office, I will be conducting a field trial of filters to find a product that will perform to these standards. As a branch of the USDA, our process for procurement of materials used for filter system design prototypes is complex and time consuming. I ask that you might work with me to supply this project with some samples on the various filter bags that you produce that may be suitable. Should the test perform satisfactorily in the trial, then there is a potential for your product to qualify in meeting the specifications for replaceable filter bags. Temperature Range: Freezing temps in winter time affect flow capacity. High temperatures not a factor for storm water application. Chemical Compatibility: N/A Particle Size: 100 to 200 microns. Most important is the life of the filter bag to retain flow capacity of filter for extended period of time. Viscosity: Water 1cP Flow Rate: net 10 gpm minimum after filtering 2,000 gallons of stormwater at a loading rate of 0.000833 lb/gal or 100 mg/l. I look forward to working with your staff to find a product that may meet the job requirements. Please call or respond via e-mail with your recommendation.
