Large-scale brackish water desalination plant in Peru for a renowned beverage manufacturer

The large-scale plant was able to treat 500 m³/h of water when it was commissioned and was deliberately designed to be flexible in terms of engineering in order to allow for changes and expansions in the plant technology and also to withstand changes in the raw water quality.

In continuous cooperation, Chriwa is supplying and expanding the industrial plant until today in 2023!

The plant is used for the desalination of brackish water and the treatment of the water as product water for beverage production. Essential components of the plant are the so-called multi-layer filtration (gravel filtration and activated carbon filtration), reverse osmosis, chlorine electrolysis, UV disinfection, ozonisation and a backwash water recovery system.

The desalination of this raw water demands a sophisticated treatment concept and the use of highly resistant materials for the equipment.

Due to the regional water shortage, there are also strict regulations for water consumption and thus particularly high demands on the efficiency of the water treatment.

Such high demands from the customer in this size dimension require excellent engineering. Chriwa supplies the water treatment technology for several large plants in Peru and neighbouring countries and has its own technical support team in the region.

As a turnkey supplier, our scope of supply and services for this project includes project planning and customised engineering, mechanical design of the equipment, pre-assembly at our factory, as well as mechanical and electrical installation, commissioning and on-site training. We also supply the plant control system with the corresponding process visualisation for this fully automatic plant.

Downstream, we offer our after-sales service with maintenance, repair, wear and spare parts and operating materials. We accompany the customers during and after the projects and remain in contact in order to continue to contribute with our expertise in process engineering.

The plant has been steadily expanded over the years to increase the plant capacity to now more than 700 m³/h of treated water. To increase the water yield, a concentrate reverse osmosis system was installed downstream of the reverse osmosis system to recover additional product water. This recycling is in the sustainable sense due to the scarcity of water and increases the profitability of the plant. In the process, water with enormously high salt contents, higher than seawater, is treated as product water. The plant technology must therefore permanently withstand such salt concentrations and use correspondingly anti-corrosive material, as well as be robust enough to withstand the high water pressures.

Chriwa regularly supplies the necessary operating materials for the plant.  This includes spare parts and the filter material for the gravel and activated carbon filters. For the membranes, correctly calculated antiscaling is important.

For 50 years now, the Chriwa Group has been supplying industries and municipalities worldwide with water treatment systems.

Regular staff that has grown over decades as well as supplier cooperations ensure the quality and continuity of our products. This enables us to achieve strong compliance with the desired water quality, so that our customers' end product reliably has the optimum properties always and everywhere.
