Technologies
for industrial water treatment
Every industrial water challenge requires a different approach and technologies that are carefully tailored to your sector, flow rates and discharge standards. From filtration to vacuum evaporation. From water softening to rental solutions, Eco-Vision offers a broad range of innovative water treatment technologies.
Membrane technology
Eco-Vision offers microfiltration, ultrafiltration, nanofiltration and reverse osmosis for process water and wastewater treatment. Membrane technology uses semi-permeable membranes to selectively remove contaminants from water. Depending on the required filtration depth, we deploy different techniques:
- Microfiltration (MF) and ultrafiltration (UF):
removal of suspended solids and bacteria - Nanofiltration (NF):
reduction of organic substances and divalent ions - Reverse osmosis (RO):
production of ultrapure water
These systems are ideal for, among others, the food industry, pharmaceuticals, metal processing and textile sectors. See also our reference projects.
Selective ion removal with ion exchangers
Ion exchangers are essential for adjusting the chemical composition of water. These systems are crucial for industries where water quality has a direct impact on process integrity. Eco-Vision’s ion exchangers provide precise removal of specific ions for water softening and demineralisation.
- Water softeners:
Removal of calcium and magnesium ions to prevent limescale. - Upflow water softeners:
water softener in which the regeneration process takes place in an upward direction.
With EVUS, Eco-Vision has developed the most efficient and cost-saving water softener for your company. - Demineralisation units:
Elimination of dissolved salts for ultrapure water. - Specific ion exchangers:
Focused on removing unwanted ions such as nitrate or fluoride.
Vacuum evaporation
Eco-Vision’s vacuum evaporators concentrate wastewater streams, reduce volume and facilitate water reuse. Vacuum evaporation is an effective method for treating complex wastewater streams.
Our vacuum evaporators offer:
- High concentration factors: Maximum reduction of waste volume.
- Energy efficiency: Lower operating temperatures thanks to vacuum technology.
- Water recovery: Possibility of reusing purified water in processes.
This technology is ideal for industries striving for zero liquid discharge (ZLD) and cost savings on waste processing.
Filtration
Industrial water filtration is the process whereby unwanted particles, sludge, micro-organisms and chemicals are removed from water to make it suitable for a specific industrial use. Eco-Vision offers various filtration technologies that respond to specific needs within different industries.
Bag filters
Bag filters are designed for microfiltration of large quantities of water. The water flows into the filter housing via the top and is distributed evenly over the filter bags. The contaminants remain behind in the bags, while the filtered water leaves the housing at the bottom. These filters are easy to maintain, as the bags can easily be replaced by hand.
Sand filters
Sand filtration is used to remove suspended solids and particles that can float or settle. Wastewater flows vertically through a bed of fine sand and/or gravel, with particles being removed by adsorption or physical entrapment. If the pressure drop becomes too high, the filter is cleaned via a backwash, in which air is injected from bottom to top to loosen the dirt.
Iron and manganese removal
Groundwater often contains dissolved and undissolved iron and manganese particles that can cause brown deposits and problems with odour and taste. The removal process usually includes an aeration stage in which the water is aerated to oxidise dissolved iron ions. The oxidised iron is then separated as flocs in a sand filter.
Activated carbon filters
Eco-Vision’s activated carbon filters offer a reliable solution for adsorbing organic contaminants and improving water quality. Adsorption is usually used for the removal of low concentrations of non-degradable organic compounds in groundwater, drinking water preparation, process water or as tertiary treatment after, for example, biological water purification.
Our activated carbon filters are characterised by:
- Low operating costs
- Easy operation
- Broad applicability
Disinfection
UV disinfection
UV disinfection is an efficient and environmentally friendly way of disinfecting water flows. During this process, the water is pumped past a UV lamp, where the ultraviolet radiation effectively inactivates bacteria, viruses and other micro-organisms.
An important condition for optimum operation is the clarity of the water. If there are too many suspended particles or if turbidity is high, the UV radiation is blocked, significantly reducing the disinfecting power.
A major advantage of UV treatment is that no chemicals are required. This means no recurring costs for reagents and no chemical load in the treated water. This makes UV technology not only effective but also sustainable and safe for both people and the environment.
Hydrogen peroxide (H₂O₂)
Hydrogen peroxide (H₂O₂) is, alongside ozone, a widely used method for disinfecting water flows. It is dosed via a dosing pump, resulting in a simple and compact installation. Depending on the application, the dosing can be set at fixed intervals or automatically adjusted on the basis of measurement signals, such as the current water quality.
Hydrogen peroxide is often combined with other techniques, such as UV disinfection, to limit the consumption of chemicals and increase effectiveness. This combined approach means lower dosages are sufficient, which saves costs and further reduces the impact on the environment. H₂O₂ is powerful, flexibly deployable and contributes to thorough and controlled water treatment without heavy chemical load.
Dewatering
Eco-Vision offers advanced dewatering solutions to remove sludge and suspended solids effectively from wastewater, which is essential for efficient and sustainable water treatment.
Chamber filter press
This technology uses square plates that form chambers in which sludge is filtered. Through mechanical or hydraulic pressure, the water is pressed out of the sludge, after which the purified water returns to the water treatment plant.
Centrifuge
Through rapid rotation, sludge particles are separated on the basis of their weight. Heavier particles are flung outwards, while lighter components move inwards, so that water is efficiently separated from sludge.
Dissolved air flotation unit
This method, also called DAF (Dissolved Air Flotation), removes suspended substances such as oil and fat by dissolving air under pressure in the water. At atmospheric pressure, small air bubbles form that attach themselves to the contaminants, causing them to float to the surface, where they can be easily removed.
These dewatering techniques help reduce waste volume, improve water quality and optimise industrial processes.
Physicochemical purification
Physicochemical water treatment is an essential part of our technologies. By combining techniques such as pH correction, chemical dosing, oxidation and sedimentation, we efficiently remove contaminants from water flows. Our solutions are flexibly deployable, both in continuous-flow and batch systems, and are tailored to the specific needs of your process. With this approach, we strive for maximum purification results and sustainable water management. Our laboratory analyses the relevant wastewater streams to correctly size the appropriate technologies. We offer physicochemical treatment in a continuous-flow/through-flow or batch system. A conventional installation with detoxification, neutralisation and dewatering (ONO) often proves to be the right choice. For rinse water, we sometimes combine this with ion exchangers in an open or closed circuit.
For this we use various techniques, such as:
- pH correction
- Dosing of chemicals
- Detoxification via oxidation or reduction
- Sedimentation
- Dewatering with a centrifuge or filter press (see above)
