Sihl and Novamem: Two Areas of Expertise, One Joint Venture
As a joint venture, we combine our core expertise:
- Sihl is a globally operating industrial membrane manufacturer.
- Novamem brings pioneering expertise in membrane technology.
Together, we develop high-performance, durable, and cost-efficient ultrafiltration (UF) modules for water filtration and water recovery.
The product concept: a replaceable filter cartridge combined with a reusable high-pressure housing. Straightforward to install, replace, and operate. This makes us the specialist in water reuse and water production.
Loop Filtration Service: Support for Your Water Project
Water quality is not created at the end of a system. It is the result of analysis, concept, technology, and operation, from a single source and across the entire process. We support you from the initial analysis through to stable plant operation.
From Project Start to Operation in Four Steps
- Understand: Analyse water quality, process, and target values.
- Plan: Design the system and filtration concept to precise requirements.
- Realise: Together we integrate the technology and commission the system.
- Operate: Support the continued optimisation of the operation.
Flamingo: Ultrafiltration System for Demanding Water Treatment
Sustainable design. Industrial performance. Easy to operate.
Flamingo is our new ultrafiltration system for demanding water treatment. It combines a replaceable filter cartridge with a reusable high-pressure housing that fits industry standards.
Technical Highlights
- Stable filter design: The unique flatsheet design* protects against membrane breakage.
- Effective flushing: Crossflow and backwash enable recovery in highly contaminated water.
- Easy to service: The replaceable filter allows efficient end-of-life maintenance.*
*Patent pending
The Result
- Cost efficient: Optimised investment and predictable operating cost.
- Fast service: Cartridge replacement on-site with minimal effort
- Low waste: The high-quality housing remains in use
How Does Ultrafiltration (UF) Work?
Water passes through three filtration stages. Each stage removes a different type of contaminant.
- Stage 1: Macro filtration → removes dirt
- Stage 2: Ultrafiltration → removes microorganisms, viruses, and bacteria
- Stage 3: Reverse osmosis → removes salt (NaCl)
Applications Across the Water Cycle
From wastewater post-treatment to drinking water production:
:
Water Reuse
- Industrial reuse
- Cooling towers
- Irrigation
Water Production
- Point of use safeguarding
- Seawater desalination
FAQ
-
What is Loop Filtration?
Loop Filtration is a joint venture of Sihl and Novamem. It specialises in water reuse and water production and develops ultrafiltration modules for water filtration and water recovery.
-
What does ultrafiltration remove from water?
Ultrafiltration removes microorganisms, viruses, and bacteria. The preceding macro filtration removes dirt, and the subsequent reverse osmosis removes salt (NaCl).
-
What makes Flamingo special?
Flamingo combines a replaceable filter cartridge with a reusable high-pressure housing that fits industry standards. Its flatsheet design* protects against membrane breakage.
*Patent pending
-
What are the benefits of the replaceable filter cartridge?
It saves time, money, and the environment. The cartridge is replaced on-site with minimal effort, and the high-quality housing remains in use.
-
What is filtered water used for?
For industrial reuse, cooling towers, and irrigation, as well as for water production, such as point of use safeguarding and seawater desalination.
