GriViA is an independent consultancy dedicated to separation process engineering, serving the Chemical, Pharmaceutical, Food & Beverage, and Water industries. We specialize in the analysis, selection, optimization, and troubleshooting of separation technologies, including membrane-based systems and conventional mass-transfer and thermal operations.

Our work is grounded in core chemical engineering fundamentals, supported by practical industry insight and techno-economic evaluation, enabling clients to make informed, unbiased, and sustainable process decisions.

 

Our Philosophy

​

At GriViA, we believe that effective separation is not defined by equipment alone, but by how well the process is understood, designed, and operated. Many operational challenges—high energy consumption, poor product quality, frequent failures, or scale-up issues—originate from incorrect technology selection or sub-optimal process integration.

We address these challenges by focusing on:

​

• Process fundamentals and performance data

• Technology-neutral evaluation

• Long-term reliability and scalability

• Commercial and operational viability

 

We do not sell equipment, membranes, or chemicals.
Our role is to protect the process—not promote products.

 

What Makes GriViA Different

​

• Vendor-Neutral Approach
  All recommendations are independent and free from supplier influence.

• Strong Engineering Foundation
  Decisions are based on mass transfer, thermodynamics, transport phenomena, and process design principles.

• Technical + Commercial Perspective
  We balance performance improvement with operating cost, energy efficiency, and return on investment.

• Confidential & Ethical Consulting
  Client data, processes, and challenges are handled with strict confidentiality.
