Water & Sewage Treatment

We always carry out our customer´s projects with care and precision
no matter how big or small the project



Water &amp Sewage Treatment

Heiligerberg fundamental objective is to achieve comprehensive platform of services, which we proudly convey in water treatment division. Heiligerberg can accomplish every mission that can outfit our client’s requirements, as well as local authorities. We process harshest industrial water through treating via our special design and solutions. We in Heiligerberg execute this wide range of projects innovations while protecting the environment is simply most important goal of our process which is built-in since design.


To protect the environment in every activity, we do.

To conserve water resources and aquatic ecosystems
To reduce waste or recycle it into a usable product
To improve the human environment by building facilities that blend into their surroundings
To provide water and wastewater treatment solutions that meet with environmental issues
To provide quality, reliability, cost efficiency and service

Zero Liquid Discharge


Zero Liquid Discharge Process

Zero liquid discharge (ZID) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle

ZLD is a process that is beneficial to industrial and municipal organizations as well as the environment because it saves money and no efficient, or discharge, is left over, ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced. Also, zero liquid discharge technologies help plants meet discharge and water reuse requirements, enabling businesses to: With all increasing demand on natural water resources and unabated pollution posed by industrial discharges into the environment, it become necessary to implement zero discharge system in industrial waste water treatment plants. In a waste water treatment facility, zero discharge theoretically means no discharge of any kind of pollutants into the environment.
