Zero Liquid Discharge
Industries that produce high volumes of concentrated wastewater often face complex challenges related to disposal and environmental impact, particularly where evaporation ponds are used. Crescent Engineering provides Zero Liquid Discharge (ZLD) solutions that enable the sustainable management of wastewater with high levels of dissolved solids and chemical contaminants—both toxic and non-toxic.
Our technologies also support the recovery of valuable materials such as salts, reagents, and metals from brine streams, transforming waste into a resource.
Industry is increasingly adopting a Minimum and Zero Liquid Discharge (MLD and ZLD) approach to improve circular water economy, recover valuable resources, and enjoy lower capital and operating costs at a fraction of a ZLD-only approach.
Crescent Engineering’s advanced MLD and ZLD solutions are designed to recover up to 100% of wastewater, leaving only solids for disposal or potential reuse. By combining technologies such as reverse osmosis and gas-based extraction, we reduce brine volumes ahead of crystallization, cutting down both capital and operating costs associated with downstream treatment. This integrated approach significantly lowers total water costs—by up to 60% compared to standalone ZLD systems—while improving sustainability performance.
​
Key benefits of our MLD and ZLD solutions include:
-
Reduced capital, operating, and lifecycle water costs
-
Increased water recovery to support environmental targets
-
Lower demand for freshwater intake and reduced wastewater discharge
-
Recovery of valuable materials such as salts, minerals, and metals
-
Modular system designs that simplify construction and minimize space requirements
Crescent Approach
With growing water scarcity and tightening environmental regulations, adopting minimum and zero liquid discharge (MLD/ZLD) has become essential across many industries. Successfully managing these complex, multi-stage treatment processes requires deep technical expertise—something Crescent Engineering delivers with confidence.
