Aeration thiab Sand Sedimentation Tank Tshuab xam zauv
Cov hauv qab no yog Aquasust rau koj los txheeb xyuas txoj hauv kev kom yog xam cov nyiaj aeration:
- Blue block yog tus tsim datameter: tau sau rau hauv
- Brown: xam cov ntaub ntawv txheej txheem
- ntsuab: qhov kawg tshwm sim rau koj cov txheej txheem
