MUNICIPAL SPA BOSKOVICE
Recycling of backwash water from swimming pool sand filters
BASIC PARAMETERS
MINT-POOL 3.0
kapacita: 7 300 m3/rok
savings: over CZK 900,000/year
operating costs: < CZK 3/m3
Solution
Previously, approximately 24 m3 of backwash water per day from three primary circuits (swimming pool, leisure pool, and whirlpool) at the Boskovice Municipal Spa was discharged into the sewer system. Based on a detailed water audit, we proposed the implementation of the MINT-POOL 3.0 recycling technology. Today, the operator saves over CZK 900,000/year. The installation has significantly reduced the consumption of make-up drinking water and lowered the load on the local wastewater treatment plant.
Warm wastewater from pools is typically either reused for sand filter backwashing or discharged into the sewer system in accordance with regulatory requirements for mandatory water replacement. The management of the Boskovice Municipal Spa decided to recycle this water, taking an important step toward a modern and environmentally responsible pool operation. Thanks to a properly designed recycling system, the treated water is reused as make-up water for pool circuits, significantly reducing both fresh (drinking) water consumption and the energy required for heating.
The MINT-POOL 3.0 system was installed in April 2023 without the need to shut down the filtration system. The unit capacity was designed for 7,300 treated m3 of backwash water per year. With a recovery rate of 89 %, the cost of recycled water remains < CZK 3/m3 even when operating costs are included.
Thanks to the recycling system, the Municipal Spa management reports the following savings:
- make-up (drinking) water consumption reduced by 61 %
- wastewater discharge reduced by 78 %
- energy required to heat fresh make-up water reduced by 60 %
Thanks to its reliable multi-barrier technology, the recycled water consistently meets the requirements of Czech legislation standards. The recycling system is officially approved and operates under the supervision of the Regional Public Health Authority.

What the customer says?
"We are very satisfied with the new MINT-POOL 3.0 technology for recycling pool backwash water. Within one month, optimal operating parameters were fine-tuned and all minor issues were resolved. Since then, the system has been saving not only pool water that would otherwise be discharged into the sewer system, but also the heat contained in that water, which would otherwise need to be replaced by heating fresh make-up water from the public supply. These savings reach 70–80% of the costs for make-up water and its heating."

WATERWORKS BEDŘICHOV
Advanced water treatment / Skid-mounted drinking water treatment plants
BASIC PARAMETERS
MINT-UF
Pilot operation completed (2021 – 2022)
specific energy: max. 0.043 kWh/m3
Celkem vyrobeno 23 800 m3 product of drinking water quality
Solution
The Bedřichov Water Treatment Plant in the Jizera Mountains is a key source for the Liberec–Jablonec nad Nisou regional water supply system. It draws raw water from the Josefův Důl dam and supplies drinking water to approximately 55 000 inhabitants, primarily in the regional capital, Liberec. The plant's average capacity reaches 190 litres of treated water per second.
The pilot operation of the MINT-UF skid-mounted ultrafiltration unit was focused on removing critical indicators (Fe, Mn, As, suspended solids, TOC, color, turbidity, bacteria) from the treated water, as well as validating self-optimizing software that adjusts operating parameters to maintain maximum recovery efficiency.
The pilot was divided into three phases, each characterized by decreasing influent water quality, sourced from different points within the existing Bedřichov treatment process. This approach allowed for detailed verification of MINT-UF operational stability under different conditions and definition of optimal process parameters.
The collected data led to the following operational parameters of the MINT-UF unit:
- Phase 1 - influent: treated water after sand filtration
recovery: 99,1 %
specific energy: 0,021 kWh/m3 - Phase 2 - influent: treated water after chemical treatment
recovery: 96,5 %
specific energy: 0,034 kWh/m3 - Phase 3 - influent: raw water from the Josefův Důl dam
recovery: 83,4 %
specific energy: 0,043 kWh/m3
During the pilot operation, more than 23 800 m3 of influent. The results clearly demonstrated that ultrafiltration is a reliable and efficient method for producing high-quality drinking water even from raw water with degraded parameters.
MINT-UF technology has thus confirmed its potential as a modern solution for intensifying drinking water treatment and ensuring long-term stability of water production that meets all relevant legislative requirements.

CONTAINERIZED QUATERNARY TREATMENT OF WASTEWATER TREATMENT PLANT EFFLUENT
JIŘETÍN POD JEDLOVOU WWTP
Advanced water treatment / Quaternary wastewater treatment
BASIC PARAMETERS
MINT-COMORES
pilot operation completed 08-10/2023
treated 500 m3 of influent
Solution
Wastewater treatment and its discharge into the environment is still largely dependent on conventional mechanical and biological processes. However, the declining quality of both surface and groundwater requires more advanced and comprehensive treatment systems based on modern technological approaches.
As part of the COMORES research project, we collaborated with partners IN-EKO, HSI, and the University of Chemistry and Technology Prague (UCT Prague) to develop the modular, containerized technology MINT-COMORES for advanced wastewater treatment and reuse. The primary objective was to implement a quaternary treatment stage (removal of micropollutants), with the option to include a tertiary stage (phosphorus removal) where required by the application.
By combining mechanical pre-filtration, direct nanofiltration, advanced oxidation processes (AOP), and disinfection, we created a multi-barrier system capable of reliably removing the vast majority of contaminants from treated effluent.
The first pilot deployment of the technology took place at a municipal wastewater treatment plant in Jiřetín pod Jedlovou with a capacity of 1 250 EO. During the three-month operation, the following parameters were evaluated:
- total influent volume: 500 m3
- kapacita technologie: 2 m3/h influent capacity
- product quality at drinking water level drinking water
Analytical data from the pilot operation showed that even at relatively small municipal wastewater treatment plants, it is meaningful to address concentrations of micropollutants, pharmaceuticals, and other contaminants that are not typically monitored in standard wastewater management.
The combination of modern separation technologies integrated into our MINT-COMORES unit has proven to be an effective solution for implementing quaternary treatment at municipal wastewater treatment plants.

Solution
Wastewater treatment and its discharge into the environment is still largely dependent on conventional mechanical and biological processes. However, the declining quality of both surface and groundwater requires more advanced and comprehensive treatment systems based on modern technological approaches.
The municipal wastewater treatment plant in Česká Lípa with a capacity of 37 000 EO was selected as a demonstration site for the unit MINT-COMORES (modular tertiary and quaternary treatment of WWTP effluent), and also for testing the more advanced technology MINT-NANOREC (an upgrade focused on efficient quaternary treatment).
Both technologies represent reliable multi-barrier systems combining mechanical pre-filtration, direct nanofiltration, advanced oxidation processes (AOP), and disinfection. Due to the significant contribution of wastewater from the Česká Lípa hospital, the demonstration focused on evaluating the impact of individual treatment steps on the removal efficiency of selected micropollutants, particularly pharmaceutical residues.
The evaluation of the demonstration operation is as follows:
- total influent volume: 23 700 m3
- average recovery: 72,5 %
- kapacita technologie: 2–4 m3/h influent capacity
- up to 85% removal efficiency for micropollutants in line with Directive (EU) 2024/3019
The quality of the resulting product reached the level of high-quality treated water:
- >99 % > 99 % removal of turbidity, color, and suspended solids
- >80 % > 80 % reduction of organic matter (TOC, DOC)
- 7 Log > 7 Log effective barrier for bacteria and viruses
The demonstration operation results clearly confirmed that modern membrane separation technologies are an effective tool for implementing tertiary and quaternary treatment at municipal wastewater treatment plants. They also demonstrated significant potential for meeting future legislative requirements regarding micropollutant removal and water resource protection.
