Zanjan Expands Capacity for Using Recycled Wastewater

With the completion of the second phase of Zanjan Wastewater Treatment Plant in October, it will cover 410,000 people in the northwestern city, the head of provincial water company said. 
“The construction of the second phase, which employs the so-called SBR [sequential batch reactor] technology, started in 2019 and has registered 80% progress,” IRNA also quoted Alireza Jozqasemi as saying.
The plant now has a capacity of treating 40,000 cubic meters of wastewater per day. When the second phase comes on stream, total recycling capacity will reach 75,000 cubic meters a day, he added.
SBR is a type of activated sludge process for the treatment of wastewater. The treated effluent can be suitable for discharge to surface waters or possibly for use on land.
