As a supplier of holistic industrial water treatment solutions we offer made-to-order and turnkey industrial plants. One example of such is this project in Peru from 2014:

In 2013-2014, we realised the largest water treatment plant in the Lima region of Peru for a renowned beverage manufacturer. The industrial plant produces internationally and nationally known softdrinks and supplies the entire north of Peru.

When it was commissioned, the large-scale plant was able to treat 500 m³/h of water and was deliberately engineered to be flexible 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 water treatment.

Such high demands from the customer on this scale 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, in addition to project planning and customised engineering, the mechanical design of the equipment, pre-assembly in our factory as well as mechanical and electrical installation, commissioning and training on site. We also supply the plant control system with the corresponding process visualisation for this fully automatic plant.

Downstream after commissioning, we offer our after-sales service with maintenance, repair, wear and spare parts and operating materials. We accompany customers during and after projects and stay in touch to continuously contribute our expertise in process engineering.

The plant has been continuously expanded over the years to increase the plant capacity to 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 a must 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.

Follow-up orders until today. For 50 years now, the Chriwa Group has been supplying industries and municipalities worldwide with water treatment systems. The quality and continuity of our products is ensured by our permanent staff, which has grown over decades, and our long-term cooperation with suppliers. This enables us to achieve strong adherence to the desired water quality, so that the end product of our customers reliably has the optimum properties always and everywhere.
