Wastewater

Wastewater quality and contained contaminants can vary wildly depending on the process which the water is taken from such as industrial, chemical or municipal.

Wastewater from industrial applications is required to meet certain criteria before discharge into drainage networks or rivers as it can contain traces of heavy metals, fibrous substances, chemicals and small solids particles. Wash water from food plants can affect Biological Oxygen Demand and Chemical Oxygen Demand with starches dissolved within the water which if discharged can lead to low dissolved oxygen levels available for aquatic organisms such as fish and insects causing them to die. 

Wastewater from municipal processes contains water from surface run off, dewatering of culverts and excess water from effluent treatment processes which is less aggressive than industrial wastewater and requires a lower grade of material choice. 

Such waste  is typically handled using centrifugal pumps with an open or closed impeller and can be used in conjunction with dosing pumps to treat water to a specific PH before discharge. 

As demand can be variable  pumps can be VFD driven to allow multiple duty points, and fitted with casing wear rings to improve life span as the wear rings wear as opposed to the casing.
