方解石
方解石过滤器具有自动反冲洗功能，可中和水的pH值
方解石是一种天然碳酸钙介质。方解石的优势之一是其自限性。正确使用时，它仅能将pH值调整至达到无腐蚀平衡。在正常条件下，它不会过度调整。酸性水与方解石接触后，会缓慢溶解碳酸钙，从而提高pH值，从而降低典型管道系统中铜、铅和其他金属的潜在浸出率。定期反冲洗可以防止填料堆积，重新分类床体并保持较高的使用率。根据pH值、水质化学性质和服务流量，方解石床体必须定期补充，因为方解石会逐渐耗尽。由于方解石中的碳酸钙会中和水，从而增加硬度，因此在中和过滤器之后可能需要使用软化剂。

Ordering Notes:
- Calcite Filters are available with USA or European style plugs and voltages. Please add the appropriate voltage code to the end of the model when ordering.
- 120V AC/60Hz with USA cord = US
- Example: W-N744ET-US
- European 220V AC = EU (EU plug is removable to convert into universal 220v cord)
- 5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
- Skid mounting, control panel and custom sizes and configurations are available upon request. AMI Calcite Filters are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
