ABOUT
ENFLOW ENGINEERING
With dynamic growth in water and wastewater management, enflow has created a new state of the art engineering department that is active in the field of wastewater treatment. We design sustainable systems, focusing on water recovery and reuse, and offer integrated solutions for the treatment of municipal and industrial wastewater.
ENFLOW ENGINEERING
TREATMENT TECHNOLOGY
Enflow having experience with all tested types of treatment, offers biological wastewater treatment systems that
apply the MBR (Membrane Bio Reactor) method.
Membrane Technology
Membrane Bio-Reactor (MBR) systems are a combination of the classical and widely used activated sludge method and ultrafiltration using membranes. The innovative feature of this method lies in the use of special membranes featuring novel technology, which are immersed in the mixed liquid (biomass – treated). The philosophy of MBR systems is based on the use of a bioreactor and membrane filtration as a single system for wastewater treatment instead of the classical system of bioreactor and final settling tank. The treated material passes through the membranes and is removed while the biomass is retained and remains in the treatment system. Thus, the final settling tanks of the activated sludge system are replaced by membrane filtration units (MF or UF type). The high concentration of biomass in the bioreactor results in achieving complete decomposition of organic matter (small quantity of excess sludge) and nitrification within a very few hours.
MBR TECHNOLOGY
BENEFITS
Today, there are several MBR systems used in a variety of applications, which are gaining ground and are even tending to replace conventional wastewater treatment methods due to the advantages of MBR technology.
Enhanced Membrane Technology
Simultaneous disinfection of the effluent produced with lower chemical consumption
Water of superior Quality
Compared to the classic treatment systems, the MBR technology can achieve high effluent quality
Reduced space requirements
Reduced footprint requirements due to the lower volume required for bioreactors.
Low sludge production
Less excess sludge to be removed due to increased residence times and low organic loading rates.
OUR PACKAGE SOLUTION
Discover the MBR Packaged Plant by Enflow Engineering
Enflow engineering designs and offers packaged systems utilizing MBR technology for the treatment of municipal and industrial wastewater. These systems represent a comprehensive solution, ready for installation with pre-installed electromechanical parts and membranes inside a container.
The systems are self-contained and fully automated, and are mounted on a concrete slab, significantly reducing the cost of installation and field construction work.
Applications
- Municipalities
- Industries
- Hotels & Resorts
- Hospitals & healthcare centres
- Military units
- Campings/ Summer camps
- Schools
- Office buildings
- Accomodation centers
- Reception centers
COMPACT WASTEWATER TREATMENT
Key Features
Our MBR packacked plants have the following benefits:
Easy to transport
Easy to transport, by its container structure
Quick assembly
With all equipment inside the container and easy commissioning thanks to the pre-assembled
installation.
Fully automated
PLC-based electrical control system for ease of operation, reduced maintenance requirements and remote monitoring.
Low operation and maintenance costs
Reliable technologies and easy operation, requiring no supervision (no need
for operator presence) with the exception of regular performance and maintenance checks of equipment and
membranes.
Scalable
The systems allow new units to be added to create the appropriate model with the necessary capacity
Portable
Ability to relocate the installation, thus adding greater flexibility to the investment
Shorter completion times
Due to reduced on-site construction work, project completion times are shorter
Less space requirements
The units require less installation space due to the compact design and high biomass
concentration.
HOW IT WORKS
4 steps in wastewater treatment
MIXER
AIR DIFFUSERS
MBR MODULES
RECIRCULATION PUMP
AIR COMPRESSOR
ODUR UNIT
A typical nutrient removal process design consists of four stages:
- The waste is sent to the anoxic tank where biological removal of nitrate is achieved. For stirring the contents in
each anoxic zone, there is an underwater stirrer in a suitable position, accompanied by a lifting system. - In the prolonged aeration stage (aerobic zone), oxygen is supplied through an underwater diffusion system in
order to achieve the biological oxidation of ammonia to nitrate, as well as the degradation of organic matter in the
wastewater. - In the final treatment stage, the MBR membranes separate the treated waste from the activated sludge via
filtration by means of pumps. - The sludge overflows into the deaeration tank to reduce DO levels and is recirculated back to the first stage.
Excess sludge is discharged through automatic valves.
