Sigma services a variety of applications in “liquid” waste treatment and management. Whether it is a “heavy metals” removal application, “organic removal” or a “Total Dissolved Solids” removal application, we have the solution for you!! Sigma combines a variety of technologies to provide a optimum economical, yet robust solution for the treatment application.
Liquid waste treatment could range in applications for “turbid” surface water, “iron, manganese or arsenic” laden ground water or a high “organic/inorganic” contaminated industrial wastewater. Removal of specific heavy metals, refractory organic and inorganic contaminant using an umbrella of latest technologies is our specialization.

Sigma offers a combination of technologies to suit wastewater recycle & reuse applications. We offer primary, secondary, tertiary & polishing membrane treatment technologies that are tailored to suit a apecific application. Often a wastewater recycle /reuse application involves:
- Microfiltration;
- Ultrafiltration;
- Reverse Osmosis; and
- Fluidized Bed Oxidation Reactor (FBOR
Sigma has supplied a variety of recycle and reuse treatment systems for several industrial applications. All our systems are guaranteed for process reuse quality and quantity.
Applications for wastewater reuse are predominantly in industries that have high water consumption for processing requirements or are a corporate mandate. Such industries benefit from internal recycle treatment when availability of water is a challenge or are mandated by governing principles in reducing discharge of trade effluents.
Zero Liquid Discharge (ZLD) is now emerging as a competitive “differentiator” between corporate philosophies. Reduction of water consumption and maximized water re-use are becoming mandatory in several corporate visions. Sigma is geared to handle such challenges with guaranteed “Return of Investments” and is able to undertake such projects as a Build-Own-Operate (BOO), Design-Build-Operate (DBO) or Build-Own-Operate-Transfer (BOOT).
