Eco-Reuse, Safer, Better Water
Addressing the world growing water demand by reusing municipal wastewater, IDE Eco-Reuse offers safer process for producing high quality potable water for either indirect potable reuse (IPR – aquifer recharge, irrigation or industrial supply) or direct potable reuse (DPR).
IDE Eco-Reuse process implementation guarantees safer and cost effective reuse process by implementing IDE’s unique proprietary technologies.
IDE Eco-Reuse process can be implemented in new reuse facilities, or for retrofitting existing water reuse facilities to improve process sustainability and produce safer product water.
Eco-Friendly, Cost Effective Process
IDE’s Eco-Reuse process uses a safe preventive maintenance approach that maintains the system constantly clean, eliminating the need for chloramine dosage and increasing the intervals between CIP. This increases the system efficiency, as well as minimizes its environmental impact.
- Direct Osmosis High Salinity (DOHS)
Injection of a short pulse of concentrated salt causes bacteria dehydrationBackwash of the membrane surface by forward osmosisRapid increase in cross flow velocity
- Conservation – periodic flushing of the membrane with permeate to dissolve scaling
Safer product –
no NDMA formation
Lower chemical consumption
IDE’s Eco-Reuse Water Purifying Process
The Story of Central Coast Blue – Advanced Water Purification Demo Facility
Central Coast Blue (CCB) is a regional recycled water project that is developing a sustainable water supply to protect the Santa Maria Groundwater Basin. The recent drought led to an implementation of the Regional Groundwater Sustainability Project and highlighted the need for a sustainable, drought-proof reliable source of water supply for future extended droughts.
In April 2017, IDE offered CCB a unique opportunity for partnership to demonstrate a new Eco-Reuse process able to provide a safer purifying process, more eco-friendly and cost effective. The process has been successfully running since early 2018, demonstrating production of safer and higher quality water.
The MVC: 38 Years of Experience
This paper describes the development of large capacity high efficiency MVC and the accumulated experience of this process in power utilities, refineries and the industrial sector.
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.
Implementation of Build Operate Transfer Schemes: Obstacles and Solutions
This paper focuses on these cases, addressing the main causes of the failure of suggested/initiated BOT scheme offerings and what prevented their successful implementation. The paper analyses the main constraints and obstacles characterizing these setbacks, and presents different solutions and alternatives to by-pass and/or overcome these obstacles that, if adopted, could enhance the possibilities of successful implementation of the projects.
