Control pH levels of trade waste water

Supplier News

H2O RX's pH Alarm and Datalogger unit provides a simple solution for managers to control pH levels of trade waste water from their commercial and industrial sites.

It is increasingly common for organisations to be heavily fined for breaches of discharge limits. pH measured at the plant discharge is one of the most common areas of breach and with the right equipment it is the easiest to protect against.

The pH Alarm and Datalogger is a system designed to provide 'best practise' pH monitoring at the point of discharge from a company’s trade waste water treatment plant.

The system consists of a lockable weather resistant enclosure and a pH sensor. The pH probe can be fitted 'in line' or submersed in a retention tank via the optional submersible probe holder.

The pH-AD enclosure houses a dual set point pH controller unit, an alarm and a datalogger.

The set points of the controller unit are set just within the pH discharge limits, which is set by the relevant authority. If the pH level of the discharge reaches these 'tighter' limits, the alarm is raised allowing the plant operator to manually dose a pH correcting chemical to ensure that there is no breach.

An automatic dosing system is also an option that can automatically correct the pH level to keep it within limits. However, if a breakdown occurs, the alarm will notify the plant operator.

The pH-AD uses the datalogger to collect readings from the controller unit. Once collected, the data can be analysed. This data can be presented to the relevant authority, showing that at no time did the plant exceed it's pH level discharge limits.

If an organisation is having pH problems, the alarm and information can be used to help manage and resolve pH level discharge problems.

If required, H2O Rx can regularly visit a company’s site, collect the data, calibrate the equipment, analyse and report on the data, thus simplifying the tasks for the operator.

The authorities generally are not out to catch organisations that are making an honest and comprehensive effort to comply with the regulations, according to H20 RX. Self auditing equipment and procedures that go beyond the requirements of the authorities are seen as a proactive approach. Benefits are generally seen as less frequent audits and a reduced chance of fines.
