Chriwa Water Solutions

Chriwa Group from Germany realises holistic water and wastewater treatment plants worldwide since 1973. This long-standing expertise offers our customers individual and sustainable water treatment technology, from various raw water qualities to product water tailored to the process, as well as sustainable processes for water recovery or safe discharge.

We offer medium to large made-to-order treatment plants for new systems, refurbishments and expansions. Where possible, we also realise solutions for the reuse of water in production, for recycling wastewater, for secondary purposes or for energy recovery through biogas to make the consumption of precious resources as efficient as possible.

With extensive expertise in all water and wastewater treatment processes, especially in the beverage and food industry, we have realised countless projects for renowned international softdrink, table water or beer producers as well as local brands.

We have strong control throughout the entire manufacturing process through our own engineering office, design, vessel construction, pre-assembly, and manufacturing on our premises.

We offer turnkey projects with worldwide assembly, on-site commissioning, process visualisation and operational data acquisition systems for remote maintenance and monitoring.

Our after-sales service, responsible for spare parts, maintenance and remote servicing, provides our customers with permanent support to ensure flawless plant operation. Our comprehensive service also includes the conversion and optimisation of plants.

The strong process engineering expertise that goes into our products in terms of efficiency, durability and savings in operating costs is highly valued by our customers. We have stood for quality and continuity for 50 years now and will continue to be your reliable partner for all matters relating to water and wastewater treatment in the future.

We are newly venturing into the north american market in 2024 together with our partner PURPLAN USA, who will also be present at our booth # LL-10611. 

PURPLAN designs and builds chemical processing plants with a focus on polyurethanes and synthetic resins manufacturing. We can support our customers through the entire project life cycle from project planning and schedule to automation control systems to turnkey project completion, commissioning, and preventive maintenance.

In a complex environment, we see ourselves as a partner of the customers for trustworthy project management along the entire value chain, including software and control technology. We know the local particularities, the individual production requirements and the mentality of our customers. We also know about the special standards, codes, and regulations for plant engineering in many countries around the world. With locations in USA, Germany (Wallenhorst) and China (Shanghai), we are where our customers need us.

What distinguishes us are a well-trained and focused team and a strong network of university professors and well-known experts who help us address specific questions and application challenges. Last but not least, we build on a high degree of pre-production. At PURPLAN, one part fits another, and on the construction site, only the piping and connection of the pre-produced units take place.

Internationally active corporations and medium-sized companies from the chemical, food, automotive, and plastics processing industries rely on our plant engineering from Germany.

We provide sustainable solutions in the areas of water and wastewater treatment for industries and municipalities. Our industrial plants, and the technology used within, ensure a steady supply of clean water for food production or as process water for industrial processes.

Our industrial plants are built to order, allowing us to engineer each project according to the customer’s needs. This approach enables one of our key advantages: designing efficient water treatment plants regarding energy use and the utilization of operating materials. This, in turn, lowers the demand for energy and operating materials (e.g., chemicals), benefiting both the environment and operating costs.

Low operating costs combined with the high longevity of our industrial plants mean that their overall costs will outcompete those of lower-quality counterparts.

We can also address environmental challenges like high water stress and support companies’ strategies for environmentally friendly production through our water recycling processes. We strive to include water-saving measures in our water treatment plants, such as concentrate recovery for Reverse Osmosis Systems.

Our wastewater treatment solutions include waste-to-energy options, such as biogas plants. This allows waste to be converted into energy and heat, which can be fed back to the production facility. This solution reduces operating costs and lowers the overall carbon footprint of the production process.

Additionally, we focus on the secondary use of wastewater. It can be treated to a high enough quality to be safely used for irrigation on facility premises, car washes, or toilet flushing. That increases the yield of the spent resource and eliminates the need for additional water to supply these uses.
