Zero Liquid Effluent Discharge System

N S Energy GroupLarge quantities of industrial waste waters/effluents with strong contaminations of different compositions are generated in the production and processes of almost all industrial sectors. These waste waters have to be treated before they can be discharged into the specified permissible system. Hence an efficient and environmentally friendly waste water treatment is required.

N.S Terbo partners with you to provide the best solutions for treatment of industrial waste waters. As one of the leading designers and manufacturers of thermal and mechanical process equipment with core competence in evaporation, crystallization, vacuum and heat transfer. N.S Terbo offers custom made plants with additional upstream or downstream process steps. Suitable combinations of processes in our plants achieve optimum results for the recovery of water and valuable products.


If the characteristics of the waste waters cannot be clearly defined and if its constituents, dry matter contents, pH or particle size change frequently, and if they have to be concentrated substantially, then thermal separation is the best solution.

During the design of evaporation plants, numerous factors have to be taken into consideration viz. waste water specific product values, power and utility costs and site condition. The type of construction and arrangement, other process engineering and operational data are based on these parameters.

Energy consumption determines the operating costs of evaporation plants. With our ingenious thermo-technical combinations, the plant energy requirement is minimal.

Energy savings are possible by:
Heating with Waste Heat
Multi-Effect Evaporation
Thermal Vapor Compression
Mechanical Vapor Compression

N.S Terbo actively takes into consideration the customer’s energy situation while designing a plant so that it offers the best possible economical solution. If specific particle sizes and products have to be removed, membrane filtration plants are combined with evaporation plants either for selective separation of the impurities, or as an initial effect to recover specific valuable matter, or to pre-concentrate before feeding to the evaporation plant, or to treat vapor condensate coming from a thermal treatment.

Research & Development
N.S Terbo has an in-house research and development centre with the required laboratory equipment, where waste waters are tested and treated for their behavior and based on the results, appropriate plant components, pre and after treatment are selected and designed. Mobile pilot plants are also available, which if required are sent to our customer’s location for carrying out tests.


Custom designed plant configurations
