Innovation in Sulphate and Molybdenum Removal

Aqua Advice have developed unique and innovative treatment methods including the use of novel technology for Sulphate and Molybdenum removal.

We have developed a method to remove sulphates from waste water via chemical precipitation and using ultrasound to enable sulphate ions to be removed. The technology was developed with the aid of a DTI grant. The technology is successfully being used on several plants in UK.

The benefits of the technology include:

• Single stage settlement and dewatering
• Process does not suffer from limescale
• Possibility the filter cake can be re-used/recycled
• Wide range of contaminants removed in addition to sulphate – heavy metals, phosphate and chemical oxygen demand
• Possibility of re-using the water using reverse osmosis. The membranes won’t foul/scale due to the quality of the water produced by the precipitation reaction.
• Process is applicable to a wide range of industries and effluents
