Astara wastewater treatment

Design landscape

Development of cities followed by an increase in water consumption and wastewater production, make it necessary to implement wastewater collection and treatment system in order to control contamination, possibility of wastewater reuse and therefore, reducing pressure on water supply resources. In addition to help we reach to the mentioned objectives, establishing a wastewater treatment plant for Astara city can lead to income through selling treated wastewater and the produced sludge.

After passing tender process and evaluating contractors, the contract to establish one module of Astara city wastewater treatment plant using EPG method was finally concluded by Sabir force participation-Mahab Qods.

The first module of the mentioned treatment plant will be designed and implemented using continuous aeration activated sludge method for a population equal to 30000 persons and with average flow rate of 6300 m3/d.
