Water & Waste Savings
水与废水的节省
The Defender? filter virtually eliminates the tremendous amount of the backwash water associated with sand filter operation. Instead of reverse flushing, as with a sand filter, Defender? simply discharges the spent media directly to waste and is recharged from time to time.
答辩者的过滤器不像砂滤器那样在操作中要用到大量的回洗水(，它几乎不用多少水）。不像砂滤器那样反冲洗，答辩者的过滤器只是简单地往废物中释放某种特定的介质，并且该介质可以随时补充。

The following chart illustrates the Backwash Water Consumption of a typical indoor waterpark attraction with a 2000 GPM (454 m3/ hr) recirculation rate.
下图给出一个典型的室内水上游乐园以2000加仑/分钟（454立方/小时）的循环速度所需要的回洗水消耗量。

The annual water savings in excess of 2.2 million gallons (8328 m3) is complemented by associated costs related to sewer expenses, chemicals, heating, power and labor.
年节约用水量超过220万加仑（8382立方），加上与下水道开支、化学剂、加热，动力和人工等有关的各项费用节省。

Backwash Water Consumption
回洗水消耗量
Energy & Chemicals Savings
能源与化学剂的节省

The dramatic rection of backwash waste directly translates to savings in make-up water along with the chemicals and fuel for re-heating. Consider the cost of chemically treating 2.2 million gallons (8328 m3) and the BTU's required to heat this volume from 50 degrees (10 °C) to 80 degrees Fahrenheit (27 °C).
回洗水的大量节省直接变成了补给水与化学剂以及再加热所需燃料的节省。不妨考虑一下，化学处理220万加仑（8382立方）废水和将这些废水从50华氏度（10摄氏度）加热到80华氏度（27摄氏度）所需的英热单位（BTU），得需要多少费用。

It is also important to note that the improved water quality generated by Defender's ability to remove finer particles will also save on general chemical consumption.
值得指出的还有采用答辩者的有精细颗粒滤除能力的过滤器带来了水质量的提高，也可以节约常用化学剂的消耗量。

Estimated annual savings ranges from $42,000 to $52,000 depending on local fuel costs for oil, gas or electricity. Based on the Backwash Water Consumption of a typical waterpark attraction with a 2000 GPM (454m3 /hr) recirculation rate.
估计年节约费用在42,000美元到52,000美元之间，这取决于当地油、气或电力的价格。这个估计是基于一个典型的室内水上游乐园以2000加仑/分钟（454立方/小时）的循环速度所需要的回洗水消耗量来做出的。

Construction Savings
基本建设节省
More savings are derived from the smaller construction footprint for Defender? filter.
答辩者的过滤器占地更少可带来更多的费用节省。

This results in as little as one-fourth to one-sixth of the space required by an equivalently sized sand system, saving installation and rigging time. The lesser operating weight of the Defender? filter reces the extent to which the floor slab must be engineered. With building costs at an estimated $75 to $150 per square foot, selecting Defender? could generate construction savings in the tens of thousands of dollars.
该过滤系统占地仅为同等大小砂滤器的四分之一到六分之一，节约了安装和装配时间。答辩者的过滤器以较轻的操作重量可在一定程度上减少底座板的施工作业。按每平方英尺75到150美元的土建成本估算，选用答辩者的过滤器可以获得数万美元的建设成本节省。

Additional Construction Benefits:
附加建造收益：
No backwash holding tank
不需要回洗水池。
Small waste line to sewer
去下水的废水管线更短
Local backwash to waste flow rate restrictions are no longer an issue
局部回洗的废水流量限制不再成为问题。

Operating weight may be as little as 10% of a similar sized sand filter
操作重量仅为同等尺寸砂滤器的10%。
