Waste Water Solutions In Spain

Coosur, Jaén, Spain

The Coosur plant in Jaén in Spain generates an average daily effluent flow of 100 m³/day (120 m³/day peak) from olive oil production.

A DAF process, pH-adjusted from 3.5 to 6.5 and dosed with coagulant and flocculant, is installed upstream of the MBR. The COD and TSS of the DAF influent is 4,500 mg/L and 700 mg/L on average respectively, with a conductivity of more than 4,000 μS/cm. The contractor and operator of the plant is Aqualia.

The project entailed the retrofit and upgrading of an existing SBR process plant to allow an increased treatment capacity and the opportunity to reuse the treated water. The filtration skid was thus coupled to the existing biological reactor to provide an effluent free from suspended solids and bacteria and thus able to be post-treated by RO to generate a product water for reuse in industrial cleaning operations. The surplus effluent is discharged to a nearby surface water. A decanting centrifuge is used for sludge dewatering, prior to it being tankered off site.

Objectives

What they needed:

Convenient hydration to support high-traffic public areas
A sustainable solution to reduce reliance on single-use plastic water bottles
A hygienic and contactless dispenser
Integration with our partner City to Sea’s Refill app to help passengers find water stations on the go.

Our Drinking Water Solution

Our Max UV bottle filling station was the perfect choice for the station, thanks to UV technology and convenient contactless dispensing.

A bottle saving counter display helps users keep track of plastic bottles saved from landfill.
A fully customisable wrap to go with Network Rail’s branding and messaging to tell passengers they can get a free water refill.
UV Sterilisation kills 99.99% of bacteria and viruses within the water
Hygienic automatic touchless dispense

“We wanted to ensure we had a free water refill provision available to all our passengers at Bristol Temple Meads so we can be more sustainable in our refreshment offerings at the station and to remove the need for passengers to buy bottled water to stay hydrated. We’re delighted to have partnered with City to Sea to promote the benefits of reducing plastic pollution and to celebrate the refill revolution.”

Conclusion

By installing our bottle filling stations an estimated 150,000+ plastic bottles have been saved from waste. This has reduced Network Rail and Bristol Temple Meads environmental footprint along with helping them to meet their ESG and sustainability goals whilst also meeting the needs of the passenger in providing filtered, clean drinking water.

This is a great example of a 360 partnership between Culligan, Network Rail and City to Sea as thousands of refills have been recorded through City to Sea’s Refill app and has helped passengers avoid single-use plastic.
