zero liquid discharge plants

ZLD Plant Manufacturer | Zero Liquid Discharge Systems for Compliance & Water Reuse Turn wastewater from a disposal challenge into a valuable resource for your industrial operation. As a trusted Zero Liquid Discharge (ZLD) technology provider and manufacturer, Shachi designs and delivers integrated ZLD systems that are engineered to recover water, reduce freshwater consumption, and minimize liquid waste generation. Shachi’s ZLD solutions combine proven pretreatment, membrane-based separation, evaporation, and crystallization technologies into a carefully integrated treatment process. The objective is to maximize water recovery while concentrating the remaining dissolved salts and contaminants into a manageable solid form, helping industries move toward minimal liquid discharge and improved water sustainability. Integrated Treatment from Wastewater to Water Recovery A successful ZLD system requires more than individual treatment technologies. Each stage must work together based on the characteristics of the wastewater, the required recovery, and the final salt-management objective. Shachi designs the complete treatment train around your specific wastewater profile: Pretreatment – Removes suspended solids, hardness, organics, and other constituents that can affect downstream membrane and evaporation performance. Membrane Treatment – RO and other membrane processes recover a significant portion of the wastewater as reusable-quality water while concentrating dissolved contaminants. Evaporation – MVR or other suitable evaporator technologies further concentrate the high-TDS reject stream while recovering additional water in the form of condensate. Crystallization – Converts the remaining concentrated salts into a solid form, minimizing or eliminating the need for liquid discharge. Water Recovery & Reuse – Treated water and condensate can be routed back for suitable industrial applications, helping reduce dependence on freshwater sources. Designed Around Your Wastewater Every industrial wastewater stream behaves differently. ZLD systems therefore need to be designed according to the actual process conditions rather than using a standard configuration. Shachi engineers ZLD plants based on parameters such as flow rate, TDS, COD, hardness, silica, chloride, sulphate, feed variability, scaling potential, fouling behaviour, salt composition, required water recovery, available utilities, and plant footprint. This application-specific approach helps improve system reliability and allows the ZLD plant to perform consistently under real industrial operating conditions. Reduce Freshwater Consumption One of the most important benefits of ZLD is the opportunity to recover and reuse water that would otherwise leave the facility as wastewater. By integrating membrane treatment, evaporation, and condensate recovery, industries can recycle a substantial portion of their wastewater back into appropriate process or utility applications. This can reduce freshwater intake, improve overall water-use efficiency, and support long-term water-security goals. Minimize Liquid Discharge Traditional wastewater treatment may still leave behind concentrated reject streams that require further treatment or disposal. ZLD takes the treatment process further by concentrating these residual streams until the remaining dissolved solids can be recovered as solid salts or crystallized material. This significantly reduces the dependence on liquid discharge routes and can support industries operating in locations where wastewater discharge is restricted or where water reuse is a strategic priority.
