Industrial wastewater treatment plants

Comprehensive solutions for the electroplating industry

We design and supply individually tailored industrial wastewater treatment systems , taking into account the type of production process, wastewater volume, its composition and the required treatment parameters.

Our solutions enable effective pollutant removal, reduction of waste and sludge volumes, as well as recovery of valuable raw materials . Systems can be designed as new installations or integrated with existing wastewater treatment plants.

Depending on the type of wastewater, we use, among others:

batch treatment – neutralization, hydroxide precipitation, cyanide oxidation, chromium(VI) reduction, chromium(III) treatment and complex decomposition,
recirculation systems with ion exchange – for treating rinse water and reducing the amount of discharged wastewater,
sedimentation and sludge separation – including the use of settling tanks and lamella clarifiers,
filter presses – for mechanical separation of sludge from water,
final filtration – using gravel filters, bag filters and activated carbon filters,
heavy metal removal using selective ion exchangers,
automatic pH correction and control before discharge of treated wastewater,
vacuum evaporators for concentrating wastewater and concentrates and reducing their volume,

The treatment process may consist of several stages and is always adapted to the parameters of the specific wastewater stream.

Sludge generated during wastewater treatment is separated from the liquid phase and subsequently thickened and dewatered.

We use, among others:

sedimentation tanks,
lamella clarifiers,
filter presses,
additional sludge drying systems.

Filter presses enable the production of a dewatered filter cake with a typical moisture content of approximately 65–70% . The resulting sludge can be sent for disposal or – if its composition is suitable – further used as a raw material.

A complete wastewater treatment system also includes safe storage and dosing of process chemicals.

Depending on requirements, we provide:

withdrawal stations for IBC ,
chemical storage tanks,
lime milk and flocculant preparation stations,
tanker truck loading and unloading stations,
liquid and dry chemical dosing systems.

Tanks can be manufactured, among others, from PP, PE or GRP with PVC lining , as single- or double-wall units with leakage monitoring and overfill protection.

Water treatment

We also offer water treatment technologies for industrial applications. Depending on the required quality, appropriately selected processes are used to achieve the water parameters required in a specific technological process.

Water treatment technologies

Depending on the requirements, we use pre-filtration, water softening, ion exchange, demineralization and demineralized water production, reverse osmosis (RO), electrodeionization (EDI) and mixed-bed filters.

System selection

The technologies are selected based on the quality of the raw water and the required process water parameters. They can also be combined with rinsing water circulation and raw material recovery systems.

Process water

Demineralized water

Ion exchange and reverse osmosis systems can produce water with a very low content of salts and contaminants.

In reverse osmosis, membranes retain most of the salts, producing a clean permeate and a concentrated reject stream . Depending on the membrane used, the process can remove approximately 97–98% of salts , with a permeate recovery of approximately 75%.

Raw material management

Secondary raw material recovery

In addition to wastewater treatment, we offer technologies that enable the recovery of valuable substances directly from prhodiumuction processes .

The separation of individual wastewater streams enables their selective treatment and the recovery of materials such as:

nickel, copper, silver, gold, palladiumium, rhodium and sulfuric acid.

Raw material recovery can reduce disposal costs, reduce the consumption of new chemicals and enable the reuse of recovered materials.

Recovery technologies

Selected solutions

Solutions are selected according to the type of recovered raw material and the characteristics of the individual wastewater streams.

Copper recovery systems
Nickel recovery systems
Cleaning and regeneration of chromium baths
Precious metal recovery
Passivation bath regeneration
Sulfuric acid recovery systems
Selective separation and recovery of metals from individual wastewater streams

>90% sulfuric acid recovery

For example, the use of a retardation system enables the recovery of na odzysk more than 90% of sulfuric acid , while reducing demineralized water consumption and the amount of sludge generated.

Control and monitoring

Process automation and monitoring

Each installation can be equipped with an automatic control and visualization system , enabling monitoring of the entire treatment process. The system can monitor, among other things, liquid levels, pH and Redox potential, temperature, pressure, turbidity, flow rate and conductivity, as well as the status of valves, pumps and agitators.

Process monitoring also includes responding to parameter changes. If specified values are exceeded, the system generates warnings or alarms , enabling continuous monitoring of the installation's operation.

Process data can also be recorded, enabling the monitoring and documentation of treatment parameters.

Tailored solutions

Solutions tailored to the process

We do not use a single universal solution for all installations. The technology is individually selected according to the type of wastewater, its volume and composition, as well as the requirements for the treated water.

Installations can be designed as complete new wastewater treatment plants or as additional modules for existing systems , allowing their capabilities to be expanded, the amount of wastewater reduced or valuable raw materials recovered.
