WasteWater Treatment TechnologyOn January 23, 2021 The Council for Scientific and Industrial Research (CSIR)-Central Mechanical Engineering Research Institute(CMERI) developed 1st ever Waste Water Treatment Technology Model, Aqua Rejuvenation Plant(ARP)’, which was inaugurated by Prof. (Dr.) Harish Hirani, Director, CSIR-CMERI along with SubhenduBasu at CSIR-CMERI, Durgapur, West Bengal.

The Integrated Waste Water Rejuvenation Model, ARP purifies wastewater for Irrigation/Farming purposes.

Purpose– To facilitate organic farming model through the treated wastewater.

About Aqua Rejuvenation Plant:

6 Stage Purification

This model does the Wastewater treatment on the basis of various purification parameters in 6 stages.

Amount of Water Rejuvenated

About 24,000 liters of water can be rejuvenated using the ARP.

This amount of water is adequate for about 4 acres of agricultural land(barring seasonal variations in water requirements).

Filtration Medium

i.The filtration medium that is used have been particularly developed to handle Indian sewage water parameters and can be modified based on geographical variations.

ii.The filter media can be obtained locally, this ensures that there is no pressure in the supply chain for the increased manufacturing of ARP.


i.The system has the following dual benefits:

  • Treated water is utilised for irrigation purposes.
  • The filtered sludge generated is used as manure / fertilizer.

ii.In addition to this, water can be saved as the biochar prepared from dry leaves falling in autumn is used to mix in  soil as it minimises the water requirement for irrigation.

iii.There is a possibility that the treated water used for irrigation can also be used for drinking water.


The Municipal Corporation, Irrigation Department and the District Administration will discuss with CSIR-CMERI for implementing the model at the required places.

Note- Earlier, the institute has used alternate technologies like the sprinkle system and others for reduced water requirements for such purpose.
