Waste Water Treatment for electroplating

A clean affair: waste water cleaned in an environmentally-friendly manner

When it comes to thorough waste water treatment, we provide not just pumps, sensors and controllers, but also our comprehensive expertise in water treatment for electroplating.

Waste Water Treatment in the Paper and Pulp Industry

Clean waste water is returned to nature

Very low-impact treatment for waste water. Our intelligent processes efficiently clean and save money too.

Cooling Water Treatment in Energy Generation

No biofilm, no bacteria, no dangerous by-products

ProMinent metering pumps allow you to keep your cool at all times as you no longer need to concern yourself with the cooling process. Alternative biocides reliably prevent deposits.

Waste Water Treatment in Energy Generation

Treating waste water quickly and thoroughly

The benefits of our waste water treatment for energy generators can be easily summed up: our waste water treatment is thorough, environmentally-sound, economical and fully automatic. Because ProMinent thinks things through.

Improved water quality in public swimming pools through the use of UV and ozone

Efficient reduction of combined chlorine with modern systems.

Modern UV or ozone systems minimise the by-products resulting from chlorine disinfection. What's more, they are easy to install, improve water quality and cut operating costs significantly.

Water Softening in Public Swimming Pools

Water softening is a key element of water treatment

Water softening is a key element of water treatment for public swimming pools. Soft water reduces the likelihood of operating system failure and ensures that the pool attractions look their very best.

Flocculation in Public Swimming Pools

Metering flocculants delivers optimum filtration

Flocculants allow the smallest of particles to be removed from the swimming pool water. In turn, our high-precision solenoid metering pumps enable the precise and continuous supply of small volumes of these flocculants.

Chlorine Disinfection

Various procedures are used to disinfect swimming pool water. Alongside the conventional metering of chlorine, use of cost-effective and environmentally-friendly electrolysis systems is also worthwhile for private pools.

Metering Flocculants delivers Optimum Filtration

Internal Water Management in Hotels and Resorts

The best water for your kitchens and laundry

Fresh bedding and sweet-smelling towels in rooms, spotlessly clean dishes and fine dining in the restaurant – desalinated and germ-free water is absolutely essential. You have the staff, we have the system technology.

Fighting Legionella in Hotels and Resorts

Squeezing out legionella and pathogens

It can be disastrous for any hotel if guests come down with legionella and seek claims for damages from the company. ProMinent provides effective solutions for eliminating legionella and other pathogens in the long term.

Swimming Pool Water Treatment in Hotels and Resorts

Absolutely essential: an attractive pool with crystal-clear water

You are an expert in pampering your guests, young and old, with everything they could desire. This usually includes an attractive swimming pool or even a luxurious spa. This is where one of our core skills come in.

Potable Water Supply in Hotels and Resorts

Only the best for your guests: clean potable water around the clock

Clean potable water is a basic requirement for guest satisfaction and therefore commercial success. ProMinent's treatment systems enable you to provide outstanding quality water all year round.

(Pre-)Oxidation of Potable Water

(Pre-)oxidation binds harmful substances in potable water

(Pre-)oxidation improves water quality by eliminating many harmful substances and improving appearance, odour and taste. No one wants to drink brown water.

(Sand) Filtration for Potable Water

Filtration removes solids from the water

Unwanted particles and turbidity are removed from the water by sand or membrane filtration. An even more effective process is to filter using upstream flocculation or precipitation. Added substances allow smaller particles to become larger, so dissolved substances can flocculate.

Desalination of Seawater and Brackish Water

Obtaining additional potable water with desalination

Drinkable water is scarce. Only a fraction of all the world's water can be consumed. So the ability to treat brackish water and seawater is of interest to many countries and islands.

Stabilisation of Potable Water

Stabilisation makes water ready for transport

After the water has been treated, its quality should not change. Stabilisation maintains the quality of the water during distribution and use.

Cleaning fruit and vegetables

Simple and reliable cleaning process for agricultural products

Fresh fruit and veg are an essential part of our diet. So it's very important for them to reach the consumer in a safe condition. Precise metering of chlorine dioxide ensures that this is the case.

Fish processing, fish and shrimp farming

Successful farming and hygienic processing

More and more people are enjoying delicacies from our seas. Fish farms and also the fish processing industry therefore face the huge challenge of producing goods quickly and hygienically. Disinfected water is essential to both industries.

Large bakeries

Baking with reproducible quality

A large share of the bakery products we consume today are manufactured by machine. Producing goods that taste just right requires precise metering of the individual ingredients.

Production of whey and cheese

Perfect water for the entire production process

To guarantee an end product fit for purpose, ProMinent ensures optimum water quality at every stage of production, thereby reliably complying with statutory hygiene standards.

Waste Water Treatment

Very low-impact treatment for waste water

Our water treatment technology delivers thorough yet environmentally friendly waste water treatment. What's more, with precisely metered additives and optimised processes, you also save money.

Swimming Pool Water Treatment

Modern water treatment and disinfection processes enhance swimming enjoyment

The use of metering technology and water treatment solutions may vary considerably depending on the industry and application. Rely on our decades of experience and know-how to find the safest and most efficient solution for you.

Potable Water Treatment

Outstanding water quality in line with global WHO standards

ProMinent turns water into hygienically perfect potable water – with powerful systems and components, which can be ready mounted for operation or individually configured.

Monitoring and Replenishing of Electroplating Baths

Demanding baths require concentration

Baths have to be monitored and replenished continually. This requires high concentration - from the sensors, controllers and pumps. Yet only small amounts of precisely fed chemicals are needed.

Disinfection of Potable Water

Germ-free potable water thanks to disinfection

As an essential nutrient, water must satisfy very strict quality controls. ProMinent offers sophisticated disinfection technology that reliably removes viruses, bacteria and microorganisms.

Monitoring and optimising surface treatment in electroplating

The right way to immerse items!

In order to attain a desired surface quality before taking further steps, such as painting, raw products are treated with various chemicals.

Sustainable use of water in industrial processes

Sustainable cycles

There are certainly chemicals that are more popular than hydrogen peroxide. But despite this, it has to be used in certain industrial processes, such as the disinfection of water.

Measured variables: pH, ORP, chlorine, chlorine dioxide, chlorite, bromine, conductivity, peracetic acid, hydrogen peroxide, ozone, dissolved oxygen and fluoride
