SYNOPSIS

Most foods industry processes generate waste streams with high pollutant that need to be treated or disposed of before discharging into the water course. In Malaysia, it has become critical issues that some raw surface water becomes contaminated by the discharge of wastewater directly from factories to drains and into rivers without adequate treatment. This has created the hazard to public health and environment that will cause big losses to any business.

A Zero Liquid Discharge (ZLD) system is a combination of technologies that work together to minimize/ eliminate the wastewater as much as technically and economically practical, often resulting in a concentrated solid product and high-quality clean water for re-use or environmental discharge. Integrating a ZLD system into your process increases resiliency by reducing both cost and risk. ZLD works to secure control over your water source and waste disposal reducing the influence of factors outside of your control. In many applications, ZLD can enable the creation of value products or energy from waste, significantly improving project economics. Overall ZLD, can help to align your profit and sustainability goals, making your business more robust and less vulnerable to outside change.

Here’s where a ZLD system comes in. The wastewater is pumped into this system, where it goes through a process which can involve heating, separation, decanting and evaporation, depending on the system used. From this there will be two end products – treated water which can be reused, and solids which can be sold, used in the industrial process, or disposed of, depending on the nature of the solid and the quality. Why is this important? It’s essential for businesses to try and limit waste as much as possible, both for the sake of the environment and for the sake of costs and profit margins. It’s also a requirement, depending on where you are in the world. Many governments have introduced strict regulations around discharge, and there are water reuse requirements in certain regions too. Eliminating waste and becoming more sustainable is hugely important, and ZLD technology can help with this, whilst also making businesses more profitable in the longrun.

Key benefits There are three key benefits to implementing a ZLD system into your industrial process:

- Minimize your waste. An efficient ZLD system will minimize, or even eliminate
- Re-use water. The water treated in the ZLD system can often be reused in the industrial process
  that required fresh water in the first place. As you don’t need as much water, your costs decrease
  as well as your environmental impact.
- Create value. The solids produce can vary, but some may be salt that can be resold, or chemicals
  that can be put to use in the initial process. This means even less actual waste is produced,
  as even the solid substances can be a benefit to your business.
