UEM has the ability to provide a complete range of operation & maintenance services with highly trained professionals with backgrounds in many process units associated with water and wastewater treatment plants. This vertical division has a crucial role in regulating the performance of treatment plants.  Our O&M team can provide training to the client’s operators who are taking care of operations on day to day basis. Due to on our long track record and experience in the field, our O&M team has acquired knowledge in troubleshooting various process units and addressing commonly encountered issues of running a plant, especially with respect to process chemistry, equipment maintenance, and engineering.

This division also spreads its responsibility towards process industries in which the upstream process can be optimized to better manage water throughout the facility.



Physico-Chemical and Primary Treatment

This is applicable to domestic and industrial sectors where, physico-chemical treatment is essential. This area will be controlled with optimized process chemistry and its application. This is not limited to any industry or domestic sector. This includes oil recovery and recycle of the wastewater. This has been under successful operations at ONGC Meshana, IOCL Panipat, BORL, and HPCL among other installations.

Anaerobic Treatment
Anaerobic biological treatment is normally provided and operated in industries that generate highly contaminated effluent.  There are very specialized skills required to operate anaerobic digesters, which is a core skill of our O&M team. This technology has been recognized as an effective way to offset the cost of effluent treatment by generating renewable energy. Our O&M team is well trained to optimize and maximize the return on investment for these anaerobic treatment systems. These have been proven successfully at NICL-Bilari, IOCL-Panipat, and Bioenergia-Guatemala, among other installations.

Aerobic Treatment
Our O&M team has experience operating a variety of aerobic biological treatment systems, including technologies such as SBR, MBR, MBBR, ASP, etc. Knowledge of process chemistry with microbiology and biochemistry allows our team to successfully troubleshoot commonly encountered problems in each type of treatment system. Our O&M team also gives standard training to the client’s operating team, with an emphasis on preventive maintenance protocols to be followed during shock loads.

Membrane Treatment
Pre-treatment is essential in any membrane treatment system, including MF, UF, and RO. UEM’s experience in designing and operating membrane based treatment systems has provided our O&M team with insight into the most commonly encountered operating issues related to these technologies. Our O&M team is trained in identifying the cause of membrane non-performance i.e. excessive fouling and scaling and can, with the help of our design center, recommend modifications in pre-treatment to address these operating issues.

Our O&M team also has experience in operating zero liquid discharge systems in which evaporation and crystallization of RO rejects is necessary to comply with environmental norms. Our O&M team realizes the critical nature of the evaporation and crystallization unit operation and is capable of troubleshooting common issues such as scaling and reduced heat transfer efficiency within the evaporation system. UEM has operation experience at HZL-Vizag, and KIADB-Bangalore, among other installations.
