| 摘要 |
A pressure unit of combined treatment of groundwater comprises a mechanical rough filter for removal of suspension from water, an ejector for saturation of water with compressed air connected to a compressor, a mechanical filter for removal of iron hydroxides, a plunger to release excess air, a filter of cationite softening, a sorption filter for removal of cationite degradation products, a mechanical fine filter for removal of suspension. Upstream of the filter for removal of iron hydroxides a saturator is located for dilution of compressed air, in the upper part of which an additional plunger is mounted to release excess air. |
