Full Description:
Napier-Reid: Pressure Filters in 6 Pump Houses in Ingersoll

Pressure Filters in 6 Pump Houses in Ingersoll, Ontario, Canada
Napier-Reid provided 6 pressure filters for 6 pump houses located in Ingersoll, Ontario, Canada. The filters are used to remove H2S, iron and manganese producing drinking water for the community.

2 pressure filters for pump houses located in West Street and Dunn's Road were required in 2004, and 4 pressure filters for pump houses located in Thompson Street, Canterbury Street, Merritt Street and Hamilton Street were required in 2006. The capacity of the 6 filters varies from 3,288 m3/day to 4,560 m3/day. The raw water is from underground well.

The Treatment Process
Working together with R.V.Anderson & Associates, Napier-Reid provided all the pressure filters.

Each pressure filter consists of a carbon steel pressure vessel (epoxy-lined interior) for a design working pressure of 100 psi, filter media (consisting of silica gravel, MD-80 and anthracite), process control valves, instruments & sensors, an air scour blower assembly and a PLC control panel. All the local control panels are linked to a SCADA panel provided by Napier-Reid.

Each polishing filter has an 80 m3 filter chamber, an underdrain system, an air scour header, and media including anthracite, silica sand, garnet sand and gravel with a media depth of 0.85 metres.

The filter is used to remove H2S from the source water. The process uses chlorine added to the raw water to oxidize much of the dissolved H2S and form a precipitate. The MD-80 media is able to remove this precipitate physically. The remaining iron and manganese are removed by the chemical reaction with the MD-80 media.

Minimum Flow:3,288 m3/day
Maximum Flow:4,560 m3/day


Effluent (specified)

Sulphide (mg/L)



Iron (mg/L)



Manganese (mg/L)



Turbidity (NTU)



The two pressure filters supplied in 2004 have been working since 2006, providing water that complies with the Ontario Safe Drinking Water Act standards for iron and manganese removal. The plant is in operation.
