Filtration to prevent solids build up in the clients wet gravity circuit

Filtration to prevent solids buildup at Tronox

THE CHALLENGE

TRONOX contracted PROXA to develop, design and commission a filtration system to prevent slimes build-up in their Wet Gravity Circuit.

OUR SOLUTION

The work we conducted included a conceptual design and feasibility study, followed by pilot plant trials to confirm the process selection and design parameters, prior to full-scale implementation. The pilot plant trials were conducted using a range of media to select the most efficient for the application.

HOW PROXA ADDED VALUE

We have a range of bench scale and pilot plant equipment for use in all water and effluent treatment applications, where the viability of conceptual design, and optimisation of technology selection, opex and capex is required to reduce overall project risk.

PROXA is not affiliated with any specific technology supplier or product, and therefor can offer an unbiased process solution. Our engineers follow a holistic approach, and select only the most suitable technology on the market for the specific application.

FEED WATER

Wash water from wet gravity circuit containing high-suspended solids.

PRODUCT WATER

Recycled solids-free water.

PERFORMANCE TARGET
