Chlorine Contact Tank Design and Design Advice

BMS' designs were calculated with reference to the Irish EPA documents 'Water Treatment Manual: Chlorination' 1998 and 2011 editions and to various US EPA and US Department of Environment documents referenced in the 1998 edition.  The effectiveness of chlorination depends on a complex relationship between a large number of variables including; micro-organisms present, temperature, pH, flow rate, seasonal variations etc., each affecting residual concentration and required residence time.  The emphasis in the 2011 EPA document is on monitored results rather than specific parameters and must be applied on an individual case basis with operating procedures determined by the relevant Local Authority. 

BMS can offer advice on Chlorine Contact Tank sizing and configuration based on individual site requirements and will work with our clients from design to installation.  Please do not hesitate to contact us.
