Hydraulic characteristics

Pressure drop

The pressure drop across the ion exchange resin bed depends on the granulometric composition, bed height and intergranular space of the exchange material, as well as the velocity and viscosity of the incoming flow. Factors that adversely affect any of these parameters, such as the presence of suspended particles in the filtrate, abnormal compression or disruption of the distribution of the resin in the bed, can lead to an increase in the pressure drop. Depending on the quality of the incoming water, the purpose and design of the plant, the flow rate can be from 10 to 40 volumes of resin per hour.

Backwash

During bottom-up backwashing, the resin bed should be expanded by 50-70% for at least 10-15 minutes. This procedure removes suspended solids, clears the bed of bubbles and voids, and redistributes the resin in the bed to ensure the least resistance to flow. When first put into operation, approximately 30 minutes of backwashing is sufficient to properly classify the bed. It is important to note that the bed expands with increasing influent velocity and decreasing influent temperature. Care should be taken to avoid resin ejection from the column if the bed is over-expanded.
