Disc TubeTM Reverse Osmosis (DTRO)

Klarwin’s technology, based on Pall’s Disc Tube Reverse Osmosis (DTRO) module, in exclusive regional collaboration with Grimm & Wulff Anlagen und Systembau GmbH, produces the best quality of treated water (permeate), which can be discharged back into the environment, used for irrigation or as process water.

This technology has the most references in treating landfills leachate, found in most of the capitals in Central, South and Eastern Europe. Worldwide, there are more than 2,000 filtration systems delivered.

The leachate treatment systems are manufactured in Germany. The specialists in Hamburg were the first worldwide to develop and manufacture reverse osmosis technology in leachate treatment, and therefore, have the longest experience in the field. The authors of these technologies have important publications in this field and, also, other patents for related technologies.

The factory in Hamburg, Germany, has a portfolio of over 2000 filtration and reverse osmosis systems for various applications such as: water desalination, industrial and military applications and, mostly, landfills leachate treatment.

The Landfill Leachate Treatment Plants (LLTP) are designed in one or more filtration steps, that can be added to obtain the desired result depending on the quality and the variable quantity of the leachate available.

The DT configuration has countless advantages over competitors’ technologies, such as:
– Easy and fast start-up and shut-downs
– No chemical pre-treatment needed
– Easy Maintenance – modules can be opened and tested, a single cushion can be replaced
– Modules are certified and approved by TUV Technischer Ueberwachuns-Verein Nord e.V.

The water quality (leachate and permeate) is constantly controlled by measuring conductivity, pH, pressure and temperature. Implementing these values into the control system leads to great reliability in operation of the leachate treatment plant.

The special cleaning agents, produced by Grimm & Wulff, are the most effective because they are specially created to clean the membranes well enough and, at the same time, not affect their performance and lifetime. Combined with up-to-date technology, it guarantees maximum process stability and reduces membrane degradation to ensure system longevity.

Choose an efficient landfill gas and biogas management solution

Klarwin®, in collaboration with top partners, offers the most efficient solution for handling of combustible gases, wherever they need to be collected, transported or removed to reduce the greenhouse effect. We are your partner for the controlled combustion of landfill gases, biogas, mining gas or industrial gases at high temperatures.

Our equipment is produced in Switzerland. Nowadays, there are more than 2,000 gas systems delivered worldwide, for any type of gas (landfill gas, biogas, industrial gas).

The technology respects the laws and norms of gas extraction and burning, meaning methane concentration of approx. 15-30%, according to the environmental legislation.

Why choose Klarwin?

• High safety standard;
• Compact automation;
• Quick installation and commissioning;
• Minimum operating, maintenance and service costs;
• Minimum on-site training.

The design of high temperature flares is based on the specific requirements of the project and the composition of the gas.

The system consists in:

  • Gas collection piping system;
  • Pump station for gas processing;
  • EeX blower for the extraction of the gas from the landfill;
  • Flare for low emission combustion of landfill gas;
  • Burner control systems approved by DVGW to provide a defined combustion process;

High safety standard

The pumping and open-flare equipment incorporates elements that are compliant with safety regulations and specifications for the landfill gas delivery and combustion. Components that come in contact with gases are free of rust and resistant to pressures up to 6 bars. The gas analysis system continuously monitors the composition efficiency of the landfill gas and stops the plant before an explosive mixture is formed in the system.

Complete technical assistance

Cloud transparency

Klarwin Monitoring System saves times and money, by providing operators the necessary information to optimize the system performance, daily. Moreover, it can proactively identify the way that the plant will perform in the future, to solve any potential problem in the system performance, prevent downtime and to maintain the desired water quality.

Our Technik Team

From a basic service package to a full one, every partner gets Klarwin’s specific support to keep their equipment in the best conditions, for a competitive total cost of ownership. The technical support is provided by dedicated service teams, in specific regions of Europe, who speak the local languages. For more details see the division Klarwin Technik.

Our After Sales Team

From the moment the equipment is installed, started-up, commissioned, and the operator is trained by a Klarwin engineer, we maintain a close contact through After-Sales services, for spare parts, predictive and reactive maintenance, technical problems and service, equipment rental.
With the After Sales Service we provide, we give you the dependability in which you can rely.
