Recently, our institute has revised some of the water supply professional standard design drawings, please use the attention of the department. The main changes can be summarized as follows: First, the pool wall brick labeling from 75 # to straight 100 # are: Special water 1001 open ion exchange filter, water 221 ~ 224 (?) And brick made rotating water distribution Clarifier, water 227 ~ 230 small water purification equipment, water 231, 232 brick suspension clarifiers, water 233, 234 brick sedimentation tanks and so on. Second, the pool wall 50 # cement mortar bricklaying to 50 # cement lime mortar bricklaying 100 # brick are: water 717-III vertical secondary sedimentation tank, water 717-IV vertical secondary sedimentation tank, water 712 contact Sedimentation tanks and so on.
