The MINT-COMORES treatment plant enables the production of high-quality and safe drinking water free from MICROPOLLUTANTS, using either municipal wastewater treatment plant (WWTP) effluent or a wide range of surface and groundwater sources.
• Replaces all other used combinations of conventional membrane separation processes: ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) with one single process step: DIRECT NANOFILTRATION (DNF) • Separation and removal of micropollutants (more than 80 %) ensures effective quaternary water treatment • High recovery rate (up to 85 %) to produce micropollutant-free potable water • Lower transmembrane pressure (1-4 bar) and energy consumption (up to 1 kWh/m3) allows low OPEX (less than 0.4 €/m3 of produced water) • Longer membrane life thanks to automatic membrane cleaning • Autonomous control system with artificial intelligence and remote access allows unattended and reliable operation.
The MINT-COMORES treatment plant signals the entrance of a new and highly innovative solution to the water treatment market. A new advanced membrane process – DIRECT NANOFILTRATION with hollow fiber membranes is integrated with feed pre-treatment and final product polishing. Comprehensive monitoring of the whole plant with remote access and a sophisticated control system utilizing artificial intelligence are also included. This containerized water treatment plant is a fully assembled functional technology which allows easy installation and Plug&Play commissioning.
The MINT-COMORES software guarantees fully automatic and safe operation thanks to the combination of online measurements and sophisticated software. Operation and process control is possible either via the main control panel equipped with HMI interface from the separate operator room or by remote access via web interface with data connection (GSM/wi-fi). This remote access enables easy operation assistance from New Water Group. The following software upgrade modules are also available: IQ-MINT is based on artificial intelligence and self-learning software. It allows the technology to adjust to real time changes in feed water quality and operating parameters. IQ-MINT can optimize technology recovery, lower operation costs and maintain maximum safety of the process. MINT-eBOOK is a software service book. This feature helps and notifies the operator and makes the operation and service extremely easy.
The produced water complies with WHO requirements and national standards in terms of its parameters, including quality and composition.
The first implementation of MINT-COMORES technology is placed on WWTP Česká Lípa effluent as a quaternary treatment solution. The pilot process plant has been running continuously for over a year within the filtration capacity of 2-5 m3/h of product water. During the continuous process, many samples have been taken and analysed. All analyses approve this technology as a suitable way to remove many types of micropollutants. The efficiency of micropollutant removal is over 90 %. The major advantage of this technology is the ability to produce full drinking water made from the effluent produced by the WWTPs.

Based on pilot process plant information there is an expected return on investment of less than 5 years.
The price of MINT-COMORES is about 280 000 EUR for the capacity of 5 m3/h of product water. There are expected further investments within the implementation of technology in ongoing processes about 40 000 to 60 000 EUR. Operating cost is calculated at about 0.5 EUR per m3 of product water.
