​Hydrogen is the element of the future in a crucial role for the green energy transition. As an energy carrier hydrogen can store energy excesses from offshore wind parks. Making hydrogen production feasible at sea is a key innovation in this. The INTENSSE-H2 project will study the feasibility of an innovative concept where water desalination AND hydrogen production through electrolysis will be integrated in a 1-step solution. This one year project officially started November 1th 2021. 

In stead of treating seawater with UF and RO to purify it the electrolyte in the process can be used as a draw solution to desalinate the sea water through a specific type of membrane.
Before developing the proof of concept which can induce the industrialisation of the concept the project team will investigate the feasibility of the concept. The central challenges are:

• The availability of commercialised alkali resistant, selective and good performing membranes for the application (fluxes)
• The effectivity of the hydrogen production and water treatment process at an offshore location on board of a moving platform that is exposed to heavy wind and tides.
• The identification of a valuable supply chain in Flanders or Europe.
• Techo-economical assesment of the membranes and the concept.
• Footprint of the assembled concept to estimate the right dimensions and loading capacity of the offshore platform.
  
  

A feasible INTENSSE-H2 concept can be of great value for the Green Hydrogen Economy: 1) lower capex and opex compared to state of the art ultrapure water treatment, 2) energy savings (low pressure), 3) smaller footprint = lower capex for floating platform, 4) higher flexibility for offshore applications.

Eco-Vision recently took care of a new water treatment installation at DAF Westerlo (BE). After the degreasing- phosphating process, each truck axle is rinsed with denim water before it is painted. The Eco-Vision installation demineralises the process water and at the same time achieves a significant reduction in the waste stream. Next to a mobile denim unit, a vacuum evaporator is also integrated into the pre-treatment process. This combined installation ensures significant environmental savings and at the same time a much higher water quality. DAF Westerlo: "Where in previous years the waste water still amounted to some 750m3, this is now reduced to just 10 to 12m3. Thanks to the commissioning of the installation, the quality is a lot better and it meets all the requirements of the Central Laboratory. It is so clear that you can see the bottom of the barrel, even after two months of production. Thanks to the new installation, regeneration is more convenient, easier to maintain and much safer. We now have a number of process parameters with which we can monitor and log the conductivity or acidity of the baths. Whereas in the past we could only start after the problem had been identified, we can now adjust proactively." The DAF-project perfectly translates Eco-Vision's approach. An approach and vision that results in both ecological benefits and operating profit. Eco-Vision, change starts with a vision!

The Evolve AFM ng filter is a hyper filter that is used in diverse applications such as pre-filtration for UF/RO installations, fine filtration, cooling towers, as a polishing step, etc. Thanks to the use of the AFM ng media and the patented Evolve controller, this unit offers:

• A stable 1-micron filtration rate
• Adsorption of organic substances
• Prevention of bacteria growth, channelling and clumping
• Prevention of transmission of pathogens
• The certainty of an SDI < 3

Green Hydrogen is a trending topic and crucial for reaching the goals of the Paris Climate Agreement. Green H2 is produced by water electrolysis, using only power from renewable energy sources such as wind or solar energy.  Hydrogen becomes the alternative 'fuel' for shipping or long-haul trucking. It can also be transformed to electricity and heat. These utilisation of green hydrogen are also referred to as PtX (power-to-X). This will make a significant contribution as an action for climate and the decarbonisation of economies. 

The water treatment unit is an important part of the electrolysis plant since electrolysers need pure water as a feedstock. Curious how we can support you? Discover how Pollet Water Group and Herco can assist you in the correct design of the unit. Watch the interview on the Aquatech 2021 show or download the Herco brochure below.

Side stream filters are designed to collect all sorts of free-floating debris from within the water system. Deposition of these particulates can cause: heat transfer loss, under-deposit corrosion, absorption of chemical treatment, pump seal leaks and a bacterial habitat.
 
By installing a magnetic filter on a side stream, typically around the main booster
set, or across a pressure differential of the system, it ensures that if the filter becomes blocked through deposit collection, it does not reduce the water circulation around the system nor cause undue stress to the pumps with back pressure from the filter. A side stream filter unit is a crucial part of a comprehensive water management system.
 
Water treatment professionals should proactively recommend the installation of these units. Don’t wait until you need a side stream filter, by that point it will cost a lot more than the original installation cost. The use of a side stream filtration unit is often the reaction to poor water quality or inefficient heating/cooling. A better understanding of the benefits of filtration in “clean” water systems will allow the proactive installation of these units to protect water systems and extend their lifetime.

The Total Capacity of the plant is 15 m³/hr physico-chemically treated, 15 m³/hr via demin-installation closed loop. The production rate is currently 16 hours/day which can be increased to 24 hours/day. This visionary project closes the entire wastewater loop by means of 4 water treatment phases. It prepares the printed circuit board manufacturer for the future and comes with a positive and direct impact on the environment. Watch our project movie below.
