Aerobic MBR reactor

Membrane biological reactor (MBR) is an advanced wastewater treatment system that combines the process of biological decomposition with membrane filtration. In the first stage, wastewater is directed to a biological reactor, where microorganisms break down organic pollutants. Then, the mixture of wastewater and sludge flows through membranes, which act as filters, retaining solid particles and microorganisms, and allowing purified water to pass through. These membranes can be immersed directly in the reactor or placed in a separate filtration module. Thanks to the use of membranes, MBR provides high quality purified water, eliminating the need for secondary settling tanks. This system is effective in removing both organic pollutants and pathogens, so it can be used for various applications, including obtaining water of drinking water quality. MBR is characterized by a compact design and the ability to work with high sewage load, which makes it an effective and versatile solution in wastewater treatment.

Ultrafiltration

Ultrafiltration is a membrane process used to purify water by passing it through semipermeable membranes that block particulate matter, bacteria, and viruses. These membranes can come in a variety of shapes, such as flat-sheet and hollow-fiber. Depending on the material they are made of, the membranes can be made of polyvinylidene fluoride (PVDF) or silicon carbide (SiC). The filtration method of the membranes can be from inside to outside (inside-out) or from outside to inside (outside-in). Ultrafiltration modes can be vacuum-driven, where water is drawn through the membranes, or pressure-driven, where water is pushed through the membranes under pressure. In both modes, the membranes retain contaminants, allowing only clean water to pass through. Due to its high efficiency in removing contaminants, ultrafiltration is widely used in the treatment of drinking water, wastewater, and industrial processes.

Container solutions

EMI has developed modular container systems in a marine version and designed to be connected into larger systems. The containers we offer have been designed from the ground up to operate in the harsh conditions of industrial sewage treatment plants. The interiors are lined with 100% stainless steel, have heating, ventilation, health and safety devices and individually configured technological equipment. The use of container construction allows for the shortest possible project implementation time. The entire installation is prefabricated in the EMI production plant and is delivered ready for start-up immediately after connection on site (in some cases preparatory works are required, such as tanks and underground networks, ground hardening, etc.). EMI's offer also includes tanks in containers that can perform averaging, storage and even become biological reactors.
