Efficient waste management and disposal is the cornerstone of sustainable development. With increasingly stringent regulations on sea, river, and deep well injection, the implementation of advanced water treatments is critical. Zero Liquid Discharge (ZLD) is the ideal solution for brine treatment and wastewater discharge – a complete closed loop cycle where discharge is eliminated and environmental regulations are met.
IDE partners with customers, particularly in the oil & gas and power industries, to achieve a ZLD plan that meets water reuse targets. Our ZLD solutions minimize the cost of disposal and environmental impact, and extract the maximum possible economic value from the effluent.
The ZLD technology converts a high volume of liquid waste to distilled water for reuse, and solid salts that can be landfilled or used as raw material for the chemical industry. It is applicable for industrial plant effluent treatment, wastewater reclamation and industrial recycling applications.
The technology used in this process is thermal evaporation and crystallization by:
- Horizontal Falling Film
- Forced Circulation Concentrator
- Forced Circulation Crystallizer
- Solid waste treatment
Offering Unique Benefits to our Partners
- End-to-end solutions that are fully customizable to a variety of water sources and customer requirements
- Recovers valuable ingredients from effluent wastewater for reuse onsite
- Reduces cost of process water disposal
- Meets strict regulatory requirements for discharge levels
- Reliable and robust solutions allow focus on main production business

Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.
Recovery of Osmotic Power in SWRO Plants
The paper analyzes the ways that different researchers have selected to overcome the phenomenon of CP, and presents an overview of the existing RO membranes from the point of view of their suitability for use in Forward Osmosis power generation.
Design Challenges and Operational Experience of a Mega MED Seawater Desalination Plant in Tianjin
This article is a continuation of the article "Sliding Pressure Turbine Integrated with Seawater Desalination Facility (MED)" presented at the IDA 2011 World Congress.
Three Pressure Retarded Osmosis PRO Processes
Pressure retarded osmosis (PRO) can be implemented on a number of water types, using different technologies and achieving various power outcomes. This paper presents the three most practical options.
Steam Driven Large Multi Effect MVC (SD MVC) Desalination Process for Lower Energy Consumption and Desalination Costs
This paper will also describe the thermodynamic advantages, the specific investment and desalination costs comparison, and the resulting desalination cost reduction potential of the steam-driven multi effect MVC process.
Three Center Design Implemented in Ashkelon SWRO Plant
This paper presents the three center design implemented in the South Israel (Ashkelon) seawater reverse osmosis (SWRO) desalination facility with guaranteed production capability of 100 Mm3 /year. The facility design is based on the concept of a Three-Center Design: a pumping center, a membrane center and an energy recovery center.
