- Swimming pool water treatment
Flocculation in public swimming pools
Precise metering of flocculants delivers optimum filtration
Flocculants allow the smallest of particles dispersed as colloids to be removed from the swimming pool water. Our metering pumps can be set with great accuracy and ensure a precise and continuous supply of precisely calculated quantities of this flocculant.
Accurate metering counts
The metering of flocculants is an effective aid to the treatment of swimming pool water. This combined chemical and physical-technical process enables the filtration of tiny colloidal particles (< 1 µm) with a negative charge. The positively charged flocculant attracts these particles and macroflocs form, which can then be filtered, allowing undesired substances to be removed from the water circuit.
Minimise the consumption of chemicals
In order to minimise the consumption of chemicals, the circulating capacity can be reduced if the water values are spot on.
As a result the proportional metering of flocculant can be reduced too – with everything regulated and controlled by ProMinent measuring and control technology.
Constant and accurate metering
One crucial factor for flocculation is the constant and accurate metering of small volumes of flocculant.
As a pioneer of solenoid metering pumps, ProMinent’s product ranges can be used to accurately set a minimum metering volume using stroke length and metering frequency.
Continuously controllable metering
Alternatively, you can use our special peristaltic pump DF4a with CAN bus control to steplessly control flocculant metering.
This way you reliably supply the desired volume to your water treatment system at all times.
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.
Membrane filtration – The right recipe for desalination
Internal water management benefits greatly from fully desalinated and soft water: expensive detergent can be saved in the kitchens, there is no need for time-consuming polishing of dishes and the quality of the food is improved.
There are fewer deposits in machines and detergent consumption is reduced in the laundry.
The heating system and steam generation are also more efficient and reliable in the long term thanks to the addition of corrosion inhibitors.
In water treatment, membrane filtration is the process for removing particles and salts in the water with the lowest operating costs – and ProMinent is a specialist in this area.
Our experts use their thorough knowledge of the industry to design a tailored complete solution with perfectly matched upstream and downstream treatment.
Complete reverse osmosis systems integrated in standard transport containers are one of our specialities.
Another is our fully ready mounted metering systems, which just have to be connected to the hydraulic and electric supply – real “plug & play”.
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.
Chlorine dioxide and ozone spell the end of biofilms
Legionella is a threat to guests and staff alike.
A temperature of 30 to 37° Celsius is ideal for legionella growth while it is reliably killed off at temperatures above 70° Celsius.
People become infecting by inhaling aerosols containing bacteria.
So showers, air conditioning systems and warm whirlpools are particular risk areas.
Biofilms, which are present in all water pipes and tanks and are resistant to most disinfection processes, are the perfect breeding ground for these dangerous bacteria if the temperature is right.
ProMinent has years of expertise in both fighting legionella in water pipes using chlorine dioxide and protecting against contamination of cooling circuits through the addition of ozone.
Efficient complete systems effectively remove biofilms and prevent them from forming again in the long term.
Added value for hotels and resorts:
- Cost savings compared with energy-intensive thermal disinfection, which causes wear to material
- Reduced staff input
- No risk of claims for damages from sick guests
Swimming pool water treatment in hotels and resorts
