Treatment of Contaminated Ground Water

Challenge:

• The Site Manager needs to treat groundwater during construction works.
• New regulations state that spillage of water needs to be as low as possible. In order to do this, the customer needs a basic treatment facility during construction works.
• The maximum flow rate is 50 m³/h during 15 min every morning.
• The effluent is built up of muddy / sandy water.
• This customer has a small footprint.
• The customer needed to minimise the amount of solids.

Solution:

• United Rentals will supply this customer a two part solution, buffer then treatment. 
• A 35 m³ tank will act as a buffer along with an Electric Submersible Pump to transfer from tank to the treatment facility with overrun.
• The customer needed to minimize the amount of solids. The solids are very fast settling therefore a United Rentals 35 m³ tank with flow breaker, overrun and snorkel could be used.

Benefits:

• This solution saves money by combining the buffer and water treatment, allowing for direct reuse.
• The quality of the final treatment is improved, allowing consent to discharge with no harm to the environment or nature.
