Zero Liquid Discharge (ZLD) Plant in South Africa
Zero Liquid Discharge Plant Manufacturer & Exporter for South Africa
Portico Environmental Services designs, manufactures, supplies and installs Zero Liquid Discharge (ZLD) Plant in South Africa for pharmaceutical, textile, chemical, dye, food processing and power industries. As an India-based manufacturer and exporter from Pune, we engineer and supply systems for projects in South Africa, including Johannesburg, Pretoria and Durban, with export packing, documentation, installation guidance and commissioning support.
Recover Water, Discharge Nothing
Our ZLD systems integrate effluent treatment, RO, advanced oxidation, evaporation and crystallization to recover the maximum reusable water and convert the remaining waste into solids, helping you meet the Department of Water and Sanitation (DWS) requirements. Recurring drought and ageing municipal infrastructure are pushing industries and estates towards on-site treatment and reuse.
Why ZLD Is Becoming Essential in South Africa
South Africa's mining, automotive, chemical and food industries, along with growing residential estates, require reliable treatment and water-recycling systems. Industries producing high-TDS and hazardous effluent are increasingly expected to recycle all their wastewater rather than discharge it.
- Regulatory expectations: many high-pollution sectors are directed towards ZLD under the Department of Water and Sanitation (DWS).
- Water security: recovered water reduces dependence on scarce fresh water.
- Sustainability goals: ZLD supports ESG commitments and export-buyer requirements.
- Local industry demand: South Africa's mining, automotive, food and beverage and chemical sectors generate high-TDS, coloured or hazardous effluent that is best managed through ZLD.

ZLD Technologies We Integrate in South Africa
Zero Liquid Discharge (ZLD) is a wastewater management approach in which all effluent is treated and recycled, with dissolved salts recovered as solids, so that no liquid waste leaves the plant. Explore our complete range of Zero Liquid Discharge (ZLD).
| Technology | Role in ZLD | Benefit |
|---|---|---|
| Pre-Treatment & ETP | Removes suspended solids, organics and hardness | Protects downstream membranes and evaporators |
| Reverse Osmosis (RO) | Recovers the bulk of water as permeate | Reduces evaporator size and energy |
| Advanced Oxidation (AOP) | Breaks down hard-to-treat organic pollutants | Improves recovery and reject quality |
| Multiple Effect Evaporator (MEE) | Concentrates RO reject | Recovers additional water as condensate |
| Crystallizer / ATFD | Converts concentrate into dry solids | Truly zero liquid discharge |

FAQs: ZLD Plant in South Africa
Do you supply ZLD plants in South Africa?
Yes. Portico Environmental Services designs, supplies, installs and commissions Zero Liquid Discharge plants for industries in South Africa, supplying projects in Johannesburg, Pretoria and Durban as an exporter from India.
Is ZLD mandatory for my industry?
ZLD requirements depend on your industry category, effluent characteristics and the conditions set by the Department of Water and Sanitation (DWS). We review your consent conditions and effluent profile and recommend the right approach.
Which technologies are used in a ZLD plant?
A typical ZLD plant combines effluent treatment, softening, multi-stage RO, multiple effect evaporators and a crystallizer or dryer. The exact combination depends on your effluent.
How can ZLD operating cost be reduced?
Maximising RO recovery before thermal stages, good pre-treatment and heat integration significantly reduce evaporator load and running cost. We design hybrid systems with this in mind.
Do you provide ZLD operation and maintenance in South Africa?
Yes. We offer ZLD operation and maintenance with trained operators, chemical supply and performance reporting.
