About Us
GEIST RESEARCH
(DIVISION OF Z-TECH INDIA LTD.)
At Geist, we specialize in delivering sustainable and profitable technological solutions for chemical recovery from industrial wastewater streams. With a strong foundation in innovation and environmental stewardship, we empower chemical industries to unlock value from waste through our advanced Zero Liquid Discharge (ZLD) and resource recovery systems.


Our turnkey solutions cover a broad spectrum of chemical recovery technologies, including:
-
Sodium Sulphate Recovery Systems using state-of-the-art sodium sulphate crystallization processes
-
Acetic Acid Recovery through advanced acetic acid distillation systems
-
Calcium and Magnesium Recovery from RO reject streams via crystallization
-
Efficient MEG (Monoethylene Glycol) Recovery using glycol distillation and purification units
-
Full-cycle Ammonia Recovery Units and DMSO Solvent Recovery Systems
-
Smart Solvent Distillation Equipment and VOC recovery solutions
-
Comprehensive ZLD solutions for chemical, textile, and pigment industries
We also provide filtration systems for chemical wastewater, reverse osmosis systems, and solutions to recover valuable chemicals like sodium carbonate (Na₂CO₃), magnesium sulphate (MgSO₄), aluminum sulphate (alum), sodium nitrate (NaNO₃), potassium chloride (KCl), and potassium carbonate (K₂CO₃).
At the core of our mission is helping the chemical industry transform wastewater treatment challenges into opportunities for profit, circularity, and environmental compliance. Our WOOW Technologies (Wealth Out of Waste) enable industries to achieve zero discharge, recover high-value chemicals, and minimize operational costs.
We don’t just treat wastewater—we engineer resource recovery.
Clear and Future-Focused Guidance

In today’s rapidly evolving industries & marketplace, the call for sustainability is growing louder than ever before.
As industries worldwide shift their focus toward a greener and more responsible future, we recognize the need to align our strategies with these changing dynamics.
At Geist, our commitment to sustainability can not only help you achieve your environmental goals but also ensure a path to guaranteed profitability even in the ever-evolving landscape of tomorrow.
What sets Geist apart is our unwavering focus on creating solutions that matter.



Addressing Water Pollution
Water pollution caused by the chemical manufacturing industry is a significant environmental concern. This type of pollution arises when chemical factories release harmful substances and byproducts into water bodies.
To mitigate this issue, regulatory agencies enforce strict environmental standards and guidelines for chemical manufacturers, compelling them to adopt cleaner production processes and efficient wastewater treatment technologies.
Geist is committed to addressing the critical issue of water pollution generated by the chemical manufacturing industry.
Geist’s approach involves the use of specialized technologies specifically designed to remove these pollutants efficiently, ensuring strict adherence to environmental regulations.
Our specialized solutions not only mitigate water pollution but also promote sustainability by implementing practices like Zero Liquid Discharge (ZLD).
This innovative approach minimizes the environmental footprint by recovering valuable chemicals and resources from industrial wastewater, turning pollution into profit.
We are dedicated to preserving water resources, fostering a cleaner environment, and providing cost-effective resolutions for the chemical manufacturing industry’s water pollution concerns.
Woow technology benefits
- Recovery of multiple chemicals from a single stream in its purest form which is then available for recycling or sale thereby generating profit.
- The residual water can be recycled back to the parent process to achieve ZLD
- Due to complete recycling, drastic reduction in the need for the purchase of fresh water
- The cost of recovery of these chemicals is typically 10-50% of the price of these chemicals, thereby making the whole project highly profitable with a payback period ranging from a few months to max. 2 years
- Creates space for expansion of activities/adds to the bottom line in a highly competitive environment.
- Savings in the cost of treatment of WW
- ZD makes statutory compliance much easier.
- Prevents secondary/tertiary damage which is difficult to quantify even with streams matching the norms.
- Eliminates the Need for land for secure landfill


From Lab to Plant Scale
Our capabilities span a wide range, from designing processes at the laboratory scale to commercializing cutting-edge technology at the plant scale. We have the expertise and experience to address the unique challenges of the chemical industry, ensuring a sustainable and prosperous future.
