Water & Waste Savings
水與廢水的節省
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.
答辯者的過濾器不像砂濾器那樣在操作中要用到大量的回洗水(，它幾乎不用多少水）。不像砂濾器那樣反沖洗，答辯者的過濾器只是簡單地往廢物中釋放某種特定的介質，並且該介質可以隨時補充。

The following chart illustrates the Backwash Water Consumption of a typical indoor waterpark attraction with a 2000 GPM (454 m3/ hr) recirculation rate.
下圖給出一個典型的室內水上游樂園以2000加侖/分鍾（454立方/小時）的循環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.
年節約用水量超過220萬加侖（8382立方），加上與下水道開支、化學劑、加熱，動力和人工等有關的各項費用節省。

Backwash Water Consumption
回洗水消耗量
Energy & Chemicals Savings
能源與化學劑的節省

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).
回洗水的大量節省直接變成了補給水與化學劑以及再加熱所需燃料的節省。不妨考慮一下，化學處理220萬加侖（8382立方）廢水和將這些廢水從50華氏度（10攝氏度）加熱到80華氏度（27攝氏度）所需的英熱單位（BTU），得需要多少費用。

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.
值得指出的還有採用答辯者的有精細顆粒濾除能力的過濾器帶來了水質量的提高，也可以節約常用化學劑的消耗量。

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.
估計年節約費用在42,000美元到52,000美元之間，這取決於當地油、氣或電力的價格。這個估計是基於一個典型的室內水上游樂園以2000加侖/分鍾（454立方/小時）的循環速度所需要的回洗水消耗量來做出的。

Construction Savings
基本建設節省
More savings are derived from the smaller construction footprint for Defender? filter.
答辯者的過濾器佔地更少可帶來更多的費用節省。

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.
該過濾系統佔地僅為同等大小砂濾器的四分之一到六分之一，節約了安裝和裝配時間。答辯者的過濾器以較輕的操作重量可在一定程度上減少底座板的施工作業。按每平方英尺75到150美元的土建成本估算，選用答辯者的過濾器可以獲得數萬美元的建設成本節省。

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
去下水的廢水管線更短
Local backwash to waste flow rate restrictions are no longer an issue
局部回洗的廢水流量限制不再成為問題。

Operating weight may be as little as 10% of a similar sized sand filter
操作重量僅為同等尺寸砂濾器的10%。
