- Location: CEPSA Refinery. San Roque, Cádiz. Spain
- Key Data: 200 m3/h osmosis water production capacity
- Technology: Reverse osmosis / Ultrafiltration
- Client: NALCO Water / CEPSA
Nalco Water awarded Savener the basic engineering project for the construction of a Wastewater Recycling Station at the CEPSA refinery in San Roque, Spain.
This project arises from the need to reduce water consumption and to be able to reuse as much water as possible by installing a water treatment system consisting of ultrafiltration (UF) and reverse osmosis (RO) modules.
The scope of the actions covers from the water intake point of the current WWTP to feed the ultrafiltration modules supplied by Nalco Water, including the storage of water in an intermediate tank prior to the reverse osmosis process, to the discharge of the rejection or brine from the process and the auxiliary installations for filter washing and chemical injections.
The water stored in the intermediate tank is also used for the cleaning of the ultrafiltration process, and the product water is used for the cleaning of the RO itself, optimising the use of this resource in the process.
This project includes, on the part of Savener, the 3D design and generation of planimetry, hydraulic, mechanical and electrical calculations, cost estimation and implementation of all the piping and equipment necessary to supply the UF and RO modules.
Savener has proposed a design and execution adapted to the implementation requirements that offers an optimal and complete solution for the plant, as well as adapted to the demanding characteristics of the refinery.
