Innovate Backwash Recycling in Microfiltration Plant: Reduce Waste to 2% of Production 创新微滤厂的反洗回收:将废物减少到产量的2%
发布日期: 2003-03-05
水处理系统中最先进的水微滤工艺 犹他州萨米特县的这家工厂正在努力证明回收的反冲洗水 初级处理过程中的水可以用作饮用水。它是 预计运行期间收集的数据将显示 回收的反洗水产生的产品与饮用水质量相同 一级处理产生。在这一创新过程中,整个工厂 废物量占整个工厂的比例从10%降至2% 生产用于冲洗膜单元的反冲洗水被丢弃 进入絮凝池和平板沉降器系统进行澄清 过程然后将澄清的水泵入另一个微滤 专门处理反冲洗水的膜装置。回收的 反冲洗水膜装置的过滤产品随后被送往 为一级处理装置提供反冲洗供水。开会 环境和政治团体制定的最高标准 将回收过程中产生的废水泵送至副产品 收集系统,导致没有打开- 现场排放。 这个项目可以产生重大成果。最近公布的研究显示 研究发现,如果目前的趋势继续下去,水资源将面临巨大的压力 随着时间的推移,我们需要更多的资源。如果像预期的那样成功,Summit County设施将 引入一种革命性的方法来保护我们最宝贵的资源之一 和商品,以98%的回收率运行。这种生态意识 这一过程将更加高效,降低成本,最重要的是,创造一个 饮用水的有效增加。包括表格、数字。
A state of the art water microfiltration process within a water treatment plant in Summit County, Utah, is on course to prove that recycled backwash water from the primary treatment process can be used as drinking water. It is anticipated that the data collected during operation will show that the filtered product from the recycled backwash produces the same quality drinking water as the primary treatment produces. During this innovative process, the overall plant waste quantity is reduced from 10 percent to 2 percent of the total plant production. The backwash water used to flush the membrane units is discarded into a flocculation tank and plate-settler system where it undergoes a clarification process. This clarified water is then pumped into another microfiltration membrane unit dedicated to treating only the backwash water. The recycled backwash water membrane unit's filtered product is then sent to the tank that provides the backwash supply water for the primary treatment units. In meeting the highest standards set by the environmental and political community, the byproducts produced in the recycling process are pumped to the wastewater collection system, resulting in no on-site discharge. This project can yield significant results. Recently released studies have found that if current trends continue, tremendous strain will be placed on water resources over time. If as successful as predicted, the Summit County facility will introduce a revolutionary way to preserve one of our most precious resources and commodities by operating with 98 percent recovery. This ecologically aware process would be more efficient, reduce cost and, most importantly, create a viable increase in potable water. Includes tables, figures.
