Aspect
|
Conventional Systems
|
Intaka Water Treatment Plants
|
|
Period of construction
|
Concrete works between 9 - 24 months for similar size plant - 1ML / day
|
Operational within 4 to 6 weeks from date of order in South Africa
|
|
Mobility
|
Fixed (Rigid)
|
Can be relocated if required - often when bulk services reach the area
|
|
Design aspects
|
Generally 20 year projection - capital underutilization during first couple of years
|
Modular options available - thus shore up capacity as and when needed
|
|
Capital and O&M
|
High upfront costs due to 'projected demand' - initially plant is greatly underutilized
|
Lower due short implementation times and modular approach - increase as demand increases
|
|
Skills level
|
Generally skilled operators and technicians required
|
Semi-skilled operator required, where training is done by Intaka Tech
|
|
Maintenance
|
Concrete spalling has significant cost implementations, especially in the last few years of its design lifespan. Often maintenance in contracted out to service providers.
|
Low maintenance due to selective fabrication materials (stainless steel) and locally available parts. Due to simplistic design, self maintenance is recommended, however maintenance contracts are available.
|
|
Flexibility
|
Process modifications are difficult to implement once installed or if water conditions change
|
Flexible and more adaptable to water changes and process modifications
