GPT provides sustainable and innovative water and wastewater treatment solutions

Effluent Treatment Plant (ETP) Manufacturer

GPT is an innovation-driven industrial effluent and wastewater treatment plants manufacturer and supplier based in Ahmedabad, Gujarat-India, offering wide range of solutions to treat and recycle industrial and municipal wastewater.


We offer advance effluent treatment solutions including primary and secondary wastewater treatment, membranes & membrane systemsfilters, filter media, prefabricated packaged ETP plants, water treatment chemicals etc.

As access to clean and safe fresh water becoming a global challenge, it is more important than ever to improve existing water and wastewater treatment processes for recycle and reuse purpose.

We provide effective and reliable effluent treatment plant solutions to various industry sectors offering sustainable and advanced solutions.  

Moreover, our thorough engineering services enable us to provide complete solutions that delivers on improved sustainability, growth and quality.

Due to its increased focus on innovation and sustainability, GPT has focused heavily in providing advanced membrane processes in treating extremely challenging and difficult wastewater effluents. 

The concentrated and contaminated wastewater from industries contain high suspended solids, organic and inorganic contaminants and other pollutants. We provide preliminary and secondary treatment of industrial wastewater. The secondary treatment includes biological and chemical treatment of wastewater. Membrane-based filtration offers numerous advantages to complex industrial wastewater treatment due to its high product water quality, flexibility, and reliability.


GPT provides thorough expertise in providing advanced membrane solutions either as a stand-alone or integrated process for industrial effluent wastewater treatment. 

Our proprietary and tailored approach has helped us achieve ambitious ESG goals using innovative membrane-based desalination and wastewater treatment solutions. GPT uses wide range of advance membrane separation processes such as ultrafiltration, nanofiltration, Membrane Bioreactor, RO, Forward Osmosis Membrane, MD, EDR etc to achieve customer's treatment goals.
