In 1982, Rochem designed a reverse-osmosis module which revolutionized the use of membranes for salt water desalination and the subsequent treatment of landfill leachate and other difficult waste waters. Rochem named this unique module Disc Tube Reverse Osmosis (DTRO). This technology has been extensively copied and is used all over the world. However, it is difficult to duplicate Rochem’s unique upgrades, our extensive knowledge in applications and engineering, and our quality of service. Rochem has been located in Hamburg, Germany since 1973 and our production facilities and standards are certified by the very exacting German testing organization TÜV.
Rochem stands for “Made in Germany”.
AFTER DTRO, ROCHEM TS HIGH CAPACITY MODULES
To complement our DT disc-tube modules, Rochem developed the TS spacer tube module series. These modules are designed to allow us to house more membrane material in the same volume as a DT module, for difficult water which contains less suspended solids. TS modules continue Rochem’s quest for proprietary module designs which heavily resist fouling. Based on your water analysis, Rochem will design and build your TS modules with the most suitable membrane for your water.
ENGINEERED FOR YOU
Backed by independent certification, ROCHEM engineers skid- or container-based or
built-in systems to specific water and space requirements. We can treat from 1 to several
thousand cubic meters of difficult water per day.
“JUST PRESS PLAY”
Our ROCHEM DTRO® systems are designed to be operated with very limited knowledge. We build them to be autonomous. Although pretreatment chemicals are not normally required in ROCHEM® systems, if they are needed they can be injected automatically into the system. If anything goes wrong, the system automatically alerts the operator and switches into a safe mode.
DESIGNED FOR YOUR NEEDS
ROCHEM DTRO systems are modular and custom-built for your requirements. Starting
from one half-tube module, we can build systems spread over several containers which can
rapidly be deployed to treatment sites around the world. If you need to expand treatment
capacity later on, we can quickly add modules as needed to keep you at full speed.
TRUSTWORTHY DRINKING WATER AT SEA
ROCHEM supplies high-quality and custom-designed DTRO systems for all types of difficult-to-treat
water. This allows us to recover fresh water from seawater with an SDI up to 15. We have a
world-wide reputation for thorough engineering, high responsiveness and German quality. As a
result, many of the World’s navies entrust Rochem to filter the drinking water for their servicemen
from seawater.
ROCHEM DELIVERS "TRINKWASSER"
We use our BIOFILT systems to treat their grey and black water before discharge into the sea or for reuse in on-board systems. Rochem has been awarded the German Navy’s rigorous
Drinking Water certification. We have engineered hundreds of ROCHEM DTRO® systems fulfill the German Drinking Water Ordinance. We have engineered hundreds of ROCHEM DTRO® systems for frigates, aircraft carriers and patrol ships, and we have developed a particularly strong expertise in the difficult subject of fitting systems onboard submarines where space and energy are at a premium.
DID YOU KNOW THAT YOU CAN DRINK BLACK WATER?
ROCHEM BIOFILT is designed to make grey and black water suitable for reuse according to marine regulations or for discharge into nature. Our effluent is so clean that it is compliant with the MEPC227 (64) standard for special areas.
Our units are self-contained and are designed to operate and self-clean automatically unlike other systems. This reduces personnel involvement and foul smells to a minimum.
WATER SO CLEAN YOU CAN SWIM IN IT
ROCHEM BIOFILT technology combines anaerobic and aerobic anoxic tanks with a series of 1 to 10 Rochem FS modules to provide a small footprint and high flow. It is therefore suitable for marine use or for size-limited applications.
If you would prefer not to surround your vessel with - and swim in - brown water and brown smells, or if you would like to truly be on the right side of marine life, ROCHEM has the solution: BIOFILT.
RETURNING LANDFILL LEACHATE BACK TO NATURE
40 years ago, ROCHEM became the first water-management company to treat landfill
leachate, the most toxic water on Earth. We return up to 95% of this water to nature, cleaner
than when it fell from the sky. We have also developed several methods to dispose of the
remaining sludge and to help you arrive at 0% discharge. Our ROCHEM DTRO systems are
capable of providing PFAS-free discharge water should your local regulations require this.
ROCHEM currently has over 200 machines handling leachate around the world.
YOUR SOLUTION FOR DIFFICULT WATER
ROCHEM DTRO provides solutions for companies in fields as diverse as bottled drinks, landfill
management and textiles to solve their water problems - discharging verifiably clean water back
into the waterways or re-using the water inside their processes.
Rochem systems are well-known for their excellent reliability. Our systems commonly clean difficult water for several decades at surprisingly low operating and recovery costs. <br
CHEMICAL CLEANERS
Our specific module designs minimize fouling, allowing us to provide a long guarantee on our RO membranes. In order to keep them in peak condition day in and day out, ROCHEM provides a line of superior cleaners and antiscalants designed for all of our membranes and the types of water that our clients use our systems to handle.
ROCHEM® units have been famous for decades for their excellent longevity. As proof of this, we are still routinely servicing systems we built over twenty years ago. Although many customers use cost of purchase as a decision-making tool, seen from the perspective of dollars per cubic meter treated, ROCHEM® is the most affordable option in almost all cases.
