Dosing Systems – automatic and monitored

A large metal can producer needed help to lower the costs they were being charged by their water supplier for their waste effluent as they were over their agreed consent level with their water company. They needed a dosing system that would automatically adjust their pH so the company could meet consent.

Monitoring, dosing and control

GWT had a solution. With the customer we  negotiated and updated the consent levels with the water company based on the work planned. A new M-cert system was designed and built to meet this agreement.

A new sewage line was needed for the client to provide their effluent treatment system, to a new M-cert weir we had designed that had an automatic testing and dosing system included.

The effluent coming from the production line had a very high pH level so we needed to bring this down to an acceptable level. The factory had a shut down for only two days throughout the year so we had to do the change over live.

For larger systems go to

It needed a hot swap over because we had a time constraint that could not wait till the two day layoff.

The Solution to pollution

We  designed and built a new sewage pipe line that went from the existing pit through to the sewage pipeline leaving the site.

To enable us to control the waste, the system takes pH readings, monitors temperature and with a flow monitoring system and auto sampler to allow samples to be taken.

 The completed works was switched over as a live system to the new sewage line with the old pipe line sealed off.
