RENOVATING AND REFURBISHING WATER TREATMENT PLANTS TO IMPROVE WATER QUALITY AND MEET CURRENT REGULATIONS

NEW FILTERS AND MEDIA, MOTORISED VALVES AND SENSORS CAN FACILITATE OPERATIONS AND REDUCE COSTS

Need some advice? We’re here to help.

The need to satisfy new or updated requirements for better water quality can often be achieved by renovating and optimising an existing water treatment plant.
New equipment such as new filters and media, motorised valves and electronic flow sensors can facilitate operations, improve the treated water quality and meet current standards.

1. RENOVAtING / REFURBISHING existing Water Treatment Plants

The need to meet the increasing requirements for improved water quality is often reached by optimising existing water treatment plants. Optimising existing systems is simpler from a resources and timeframe point of view.

Typical reasons for renovation a water treatment plant are:

automation and supervision
environmental protection
reducing operational costs
increasing production capacity with modern equipment
WHS reasons

The first stage before renovating an existing plant consists of deciding which parts need to be replaced and which can stay. This decision will be made based on the goals that the renovation is aiming to achieve.

A second stage will include a project schedule with decommissioning, installation and commissioning times and a rough costs estimate. This schedule is a critical part of the renovation project as will provide a first estimation of downtime/shutdown as well as impact on the overall water plant production. In many occasions the water supply cannot be interrupted and new processes will have to be installed and commissioned before the old water treatment equipment is decommissioned.

Schedule and budget estimate must both be approved by all stakeholders as part of the go/no-go decision.

2. HOW RENOVAtING / REFURBISHING A Water Treatment Plant can be helpful

Optimising hydraulic conditions, filtering media and adding a PLC integrated control can increase the volume of treated water and/or deliver a higher quality product:

Replacing filtering media: replacing tradicional filtering media (sand and anthracite) with modern high rate filtering media can significantly increase the quality and volumen of treated water

Modernising the control system can decrease the number backwash cycles, optimise performance and reduce operational costs

Modifying chemical treatment: Replacing a coagulant, adding an oxidant or including remineralization (CO2 + lime)

Other reasons for upgrading can be protecting the environment, reducing the footprint of the treatment plant or operational health and safety concerns.
