Gratt Ultrafiltration System
High Performance, Operational Safety and Superior Water Quality.
O Gratt Ultrafiltration (UF) System is an advanced solution for water and wastewater treatment, designed to deliver high quality standards, operational stability and continuous reliability.
Applied as a polishing step, advanced treatment or pre-treatment for reverse osmosis, the system transforms treated water into a strategic resource for industrial processes, reuse systems and applications that require rigorous physical-chemical and microbiological quality control.
The engineering of Gratt Industry and Environmental Technology develops tailor-made ultrafiltration systems, integrated into complete WTP, ETE and industrial reuse plant solutions.
What is thin membrane technology?
O Thin Membrane Water Treatment System is a physical separation technology that uses selective barriers with microscopic pores to remove contaminants from water.
Depending on the degree of filtration, it can operate for:
- Microfiltration (MF) – retention of suspended solids, colloids and part of the bacteria;
- Ultrafiltration (UF) – removal of viruses, bacteria and fine particles;
- Nanofiltration (NF) – reduction of hardness, color, pesticides and part of dissolved salts;
- Osmose Reversa (OR) – removal of salts, dissolved metals and low molecular weight contaminants.
This technology allows the production of water with a high quality standard, which can meet industrial applications, reuse, potability or processes that require strict control of physical-chemical parameters.

What is Ultrafiltration for?
Ultrafiltration works to remove:
- Suspended solids;
- Colloids;
- Bacteria;
- Virus;
- Macromolecules.
The process guarantees water with low turbidity, high clarity and stability, even in the face of variations in the quality of the incoming water.
It is an ideal solution for:
- Reuse of industrial water;
- Polishing of treated effluents;
- Pre-treatment for reverse osmosis systems;
- Process water treatment;
- Applications that require high microbiological standards.
How the Gratt ultrafiltration system works
Gratt UF systems utilize high efficiency membranes, capable of retaining microscopic particles while allowing superior quality water to pass through.
The operating principle is based on physical separation by selective barrier, operating under controlled pressure. Water passes through the pores of the membrane, while contaminants are retained.
The system is composed of:
- Ultrafiltration membrane modules;
- Pumping system with pressure control;
- Automatic backwash steps;
- Chemical cleaning systems (CIP) when necessary;
- Instrumentation for monitoring flow, pressure and performance;
- Automation and continuous control panel;
- Integration with ETA, ETE systems and reuse plants.
The system operates with automatic filtration and cleaning cycles, ensuring hydraulic stability and extending the useful life of the membranes.
Why is UF strategic for the industry?
With increasing water scarcity and more stringent environmental requirements, ultrafiltration has become an essential technology for operations seeking to:
- Constant quality of treated water;
- Reduction of operational risks;
- Greater efficiency in reuse systems;
- Protection from later stages, such as reverse osmosis;
- Compliance with ESG goals and sustainability policies.
More than treating water, the system ensures predictability, safety and control of the process.
Integration with treatment systems
Ultrafiltration can be applied as:
- Tertiary polishing step;
- Pre-treatment for reverse osmosis;
- Microbiological barrier in reuse systems;
- Complementary solution in industrial treatment.
Gratt engineering sizes the system according to:
- Required flow;
- Quality of incoming water;
- Desired quality standard;
- Specific industrial application.
