Wastewater Recycle Plant (ZLD)

Wastewater Recycle Plant (ZLD)

Our Wastewater Recycle Plants are engineered to recover and purify industrial wastewater into high-quality process-grade water. By integrating advanced biological, membrane, and filtration technologies—including Membrane Bio-Reactor (MBR), Ultrafiltration (UF), Submersible UF, and Reverse Osmosis (RO)—we help industries achieve Zero Liquid Discharge (ZLD) targets, satisfy environmental regulations, and reduce operating costs.

Description

Core Technology Scope & Treatment Capabilities

Our multi-barrier treatment approach utilizes specialized filtration technologies tailored to your raw wastewater characteristics.

01

Membrane Bio-Reactor (MBR)

Integrates conventional activated sludge treatment with low-pressure membrane separation. Eliminates secondary clarifiers and yields high-clarity effluent.

  • Footprint reduced by up to 50%
  • Produces low-turbidity feed for RO
  • Removes biomass & suspended solids

02

Ultrafiltration (UF)

A pressure-driven separation process removing suspended solids, bacteria, viruses, and macromolecular organic matter down to 0.01–0.1 microns.

  • Automated backwash and CIP cycles
  • Protects downstream RO systems
  • Consistently maintains SDI < 3

03

Submersible UF Filtration (SUF)

Immersed membrane modules operating directly inside high-solids aeration or filtration tanks via low-pressure vacuum suction.

  • Low operational energy requirements
  • Handles high organic loading rates
  • Easy modular capacity expansion

04

Reverse Osmosis (RO)

High-pressure membrane technology designed to separate dissolved inorganic salts, heavy metals, and trace compounds from water.

  • Up to 98%+ TDS removal efficiency
  • Enables reuse for boilers and cooling towers
  • Core driver for ZLD plant layouts

05

Multiple Effect Evaporator (MEE)

A thermal concentration technology that reuses vapor latent heat across multiple stages to evaporate high-salinity RO reject and achieve Zero Liquid Discharge (ZLD).

  • High thermal energy efficiency via multi-stage steam reuse
  • Converts concentrated brine into reusable condensate water
  • Achieves total liquid elimination with dry salt crystal recovery
