That’s why we don’t offer off-the-shelf systems. We design and deliver customized water treatment solutions that are engineered to meet your exact specifications.
Whether you're working in mining, oil & gas, F&B, municipal, or power sectors, we take the time to understand your site, your goals, and your operational demands — then build a solution that fits.
Minimal Liquid Discharge
Alba Water & Process Solutions helps to address wastewater regulatory challenges with our minimal liquid discharge (MLD) solution. MLD has the potential to minimize operating costs of achieving high water recovery while reducing the amount of energy required to operate compared to traditional ZLD processes. With the industry’s broadest portfolio of purification and separation technologies, our solutions can provide cost savings, higher recovery, and improved environmental stewardship.

Zero Liquid Discharge
Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste.
While many water treatment processes attempt to maximize the recovery of freshwater and minimize waste, ZLD is the most demanding target because the cost and challenges of recovery increase as the wastewater gets more concentrated. Salinity, scaling compounds, and organics all increase in concentration, which add costs associated with managing these increases. ZLD is achieved by stringing together water treatment technology that can treat wastewater as the contaminants are concentrated
Benefits of Targeting Zero Liquid Discharge (ZLD) in Industrial Operations
- Lower waste volumes decrease the cost associated with waste management.
- Recycling water on-site lowers water acquisition costs and risk. Recycling on-site can also result in fewer treatment needs, versus treating to meet stringent environmental discharge standards.
- Reduce trucks associated with off-site wastewater disposal and their associated greenhouse gas impact and community road incident risk.
- Improve environmental performance and regulatory risk profile for future permitting.
- Some processes may recover valuable resources, for example, ammonium sulfate fertilizer or sodium chloride salt for ice melting
Desalination Plant
Seawater desalination is how we remove salt and impurities from seawater to produce drinking water. Our desalination plants use a reverse osmosis process. Seawater is pumped into the desalination plant from the Indian Ocean and passes through pre-treatment filtration to remove most particles.
The filtered seawater is then forced under pressure through special membranes. The osmosis process that occurs in nature is reversed. The pores in the membranes are so tiny that salt, bacteria, viruses and impurities separate from the seawater. In essence, they act like microscopic strainers. About half of the water that enters the plant from the sea becomes fresh drinking water. The salt and impurities removed from the seawater is then returned to the ocean via diffusers. This ensures the salt concentrate mixes quickly so it doesn't impact the marine environment.
We then treat the desalinated water to meet drinking water standards
