Haya uses advanced technology for waste water treatment
Wastewater treatment and its reuse contributes to reducing the spread of epidemics and diseases and helps create a healthy environment.
Haya Water has been working, since its establishment, to introduce the latest technologies in the field of wastewater treatment and to use this water to make Oman greener and healthier and to maintain public health.
It uses the Intermittent Cyclic Extended Aeration System (ICEAS) and Membrane and Bioreactors System (MBR) as substitutes for traditional wastewater treatment systems.
The treatment using Extended Aeration and Activated Sludge systems in Wastewater Treatment Plants (STPs) is considered traditional.
On the other hand, the company says the modern technologies it uses offer several advantages compared with the other technologies.
These technologies include Extended Aeration System (EAS), a process in which ventilation and sedimentation processes are carried out in the same tank. In the traditional method, the two processes are carried out in separate tanks.
EAS technology has been modified and now called Intermittent Cyclic Extended Aeration System (ICEAS). Here, wastewater is constantly supplied into the treatment tanks and an isolation wall is used to reduce the continuous flow of water.
Membrane and Biological Reactors System (MBR) is an advanced technology that uses Extended Aeration and Activated Sludge. It separates water from solid materials and produces high quality treated wastewater due to the tiny pores that are only 0.04 microns.
The advantage is the high quality treated water which can be used for irrigation purposes.
The disadvantages are high costs of operation and maintenance, and the need to control contaminants in wastewater such as oils, grease, sand, stones and chemical substances that adversely affect the operation of membrane reactors and block the tiny pores.
The Operations & Maintenance Division is responsible for managing the networks, pumping stations and STPs and monitoring all the processes and phases of wastewater treatment, starting from the house connections to the wastewater network, into the sewage treatment plants (STPs) and finally pumping the treated wastewater into the distribution networks for irrigation of gardens and parks.
O&M Division also transfers the partially dried sludge to the organic compost plant in Al Amerat and then blends it with organic materials such as leaves and branches to produce organic compost.
This project aims to protect the environment from pollution and contribute in controlling the emission of harmful carbon into the atmosphere and environment by reusing solid waste as an environmentally friendly product called ‘Kala’ compost.
