The disinfectant (sodium hypochlorite) and the flocculant (polyaluminum chloride) are added.
A diaphragm pump is used for the chemical injection pump, which poses the following problems.

• The injection volume cannot be measured with a flow meter due to the pulsation of the pump.
• To check the concentration, it is necessary to go from the administrative building of the facilities to the clean water tank.

The customer viewed a demo Smoothflow Pump and checked that measurement was possible with a flow meter.
Our technicians met with the customer multiple times until we were able to provide them with a device that is capable of the desired flow rate control.

• Because of the constant flow with no pulsation, it is now possible to measure the actual injection volume with a flow meter.
• Actual injection volume feedback is performed, enabling highly accurate injection.
• The flow rate can be controlled from the administrative building of the facilities, eliminating the need to go to the clean water tank.
• Running costs have been reduced thanks to a reduction in the amount of wasted chemicals.
