Wastewater treatment plant intensification in PIKA Bzenec (CZ) factory
A new IC reactor start-up is planned in PIKA Bzenec cannery in August. The factory is increasing production and the hydraulic loading at WWTP is increasing, too. That is why the customer has decided to intensify their plant, which will include extending the existing anaerobic volume with a new same size IC reactor. Part of the intensification will be the installation of more powerful pumps for IC, new biogas treatment ( gasholder with flare for burning excess biogas), increasing of NaOH preparation unit capacity, waste air treatment and new aeration system in the post-aeration tanks. The WWTP capacity will increase from 733 to 1 100 m3/d. Mass loading will change from 5 000 to 7 500 kg/d with 85 % efficiency of COD removal.
Wastewater treatment pilot plant for industrial waste water
For several months, Hydrotech has intensively dealt with pilot plant testing of food industry waste water with high concentrations of organic compounds (COD), sulphur and dissolved inorganic salts. In the first phase, aerobic bacteria were applied so oxygen was needed for them to be able to treat them. After several important adjustments of technology, the process began to work perfectly and the system treats the waste water not exceeding required limits. In the second phase, Hydrotech made a decision to try to treat waste water in anaerobic way. The high loaded IC reactor parameters and treating limits are determined by gradual system loading. Pilot testing results seem very promising, so far.
The assembly team has travelled across the Atlantic
A waste water treatment plant construction process in North Dakota for an emerging distillery has reached the point when assembly could begin. The team of Hydrotech´s employees with a chief fitter and technologist left company´s headquarters in Vinosady, Slovakia and started to work on assembly in the USA. The current situation is favourable – the high loaded anaerobic IC reactor has been almost completely finished, as well as the flotation unit for removal of aerobic sludge and the sieve for bigger particles removal at the WWTP inlet.
Hydrotech Slovakia is at the beginning of a new project management system
Our latest Slovak project for bakery is going to be a pilot application of the new project management system. Chief project engineer will be responsible for coordination of processes of design, production and execution itself. Brief meetings intensity has increased pleasantly and internal communication has started to improve significantly. If we´ll succeed improperly implementing this new project management system, we will be able to make our effort much more effective.
Teambuilding of HYDROTECH s. r. o.
A traditional sport and grill afternoon took place on 25th of April 2019. This event started with a favourite game Kubb initiated by one experienced player – our colleague Lenka Silhankova. After that, we were shooting an air rifle and finally we have enjoyed perfectly prepared meat and cold beer. These events always contribute to an informal atmosphere and debates among people. Moreover, our colleagues from Prague also joined us. We are looking forward to next grill afternoon.
Waste treatment tests from dairy industry in anaerobic way
Treatment tests of concentrated waste material from dairy factory are currently being run in our laboratory. Process advantages are as follow: biogas production, transformation and reducing of problematic waste. We do recommend this material as a co-substrate for bigger biogas stations.
We treat waste water from bakery
Because of a new project in Slovakia our technologists and designers are busy these days. This new factory will produce several kinds of bakery products. Therefore, when you enjoy a croissant next time, be aware that perhaps Hydrotech also participated in its production.
It is possible to treat condensates from industrial productions in anaerobic way
If your company produce waste water including condensates, as does our customer in Kaluga (RUS), then be careful in the next steps of treatment. There is lack of salts or ions in condensates. These particles are as important for biological processes as minerals and vitamins for human body. If this problem occurs in your production line be aware that these particles must be dosed into system. This fact was a really essential conclusion after our technologists’ visit in Russia. Their waste water treatment plant equipped with high loaded anaerobic IC reactor was continuously losing its efficiency.
Get rid of heavy metals in your water
Our lab is quite a busy place to be these days. We recently finished an experiment involving heavy metals removal from waste water. Tests were followed by waste water treatment plant designed draft. The results were very satisfactory and we have reached more than 95 % efficiencies in terms of heavy metals´ removal. If you are interested in this topic you can get more information reading our blog.

Taking care of our customer Rajo, a.s.
Couple months have passed since Rajo, a.s. dairy waste water treatment plant start-up. We are glad that the required effluent limits are met and the plant works well. Priceless advantage is that Hydrotech and Rajo, a.s. are in a close geographical vicinity and therefore our chemical technologist and our service regularly visit the WWTP. Never-ending will to have good relationships is what our company does constantly.
Trip to Brazil and inspection of IC reactor´s parts preparation
As our company cares about smooth running of the U.S. project, a vice managing director was sent to check the production of parts of the anaerobic IC reactor to Brazil. Along with the excursion in the production, meetings were held with the management of partners – Paques Brazil. Probably anybody would be happy to enjoy Brazilian summer for a couple of days in the middle of Slovak winter.
A friendly visit of our manager to our partners
Our management team travelled across the ocean to visit our partners in North Dakota before technology delivery and start of assembly. The main aim of visit was to improve mutual relationships and planning of the key project point. After pleasant but also tough days the Hydrotech managers came back home.
Preparation for export of technological parts of the wastewater treatment plant to the U.S.
Intensive production, preparations and transportation planning for the U.S. project were taking place during last months in Hydrotech´s production halls. Parts of technology will be transported across Europe, then loaded onto a cargo ship in Polish harbour, subsequently sail across the ocean and travel thousands of kilometres across the USA from the east coast to North Dakota. To make it more “interesting”, one part of technology will be transported from Brazil.
Anaerobic reactor start-up in the starch factory´s wastewater treatment plant
A waste water treatment plant in starch factory was built in Kaluga city (south of Moscow) two years ago. After stabilization of the production processes, a highloaded IC reactor was ready for start-up. Hydrotech technologists from Latvia, Russia and Slovakia faced several difficulties as low quality and activity of granular sludge, sludge washout, etc., but at the end of the day the process was successfully run in.
Hydrotech usual Christmas meeting
Hydrotech employees met at pre-Christmas meeting last December. The official part summarized the last year, plans for the next one was mentioned, some long-time employees were awarded and the company´s management wished merry Christmas to all employees and their families. Informal part followed with tasty food, possibility of leisure activities and a space for personal talks.
Beginning of the construction of a new wastewater treatment plant in the Russian federation
Another project arises from paper form and is becoming a reality. Wastewater treatment plant in the southwest of The Russian Federation is in a process of building and assembling of the technological part. The size of the wastewater treatment plant could be compared to the city with 120 000 inhabitants. The start up of the WWTP is planned for the end of spring 2019. Well, good luck to our employees working during tough Russian winter.
Excel training – 2nd round
There was a Microsoft Excel training early this November which was organized for employees who did not take part in previous summer training. They have been trained in intermediate level and topics such as formatted tables, datasheets, types of formatting, pivot tables etc. were taught. We believe the work and workplace for our employees will be more comfortable and we are glad about development of their skills.
Successful final inspection of WWTP in the Rajo a.s. dairy
Successful final inspection of waste water treatment plant for our customer Rajo a.s. (Meggle group) was completed. The autumn 2018 will be added to the Hydrotech archive with this note. WWTP started to run in automatic mode after more than half a year of planning, building parts and technology assembles. After competent authorities visit the WWTP operation was approved. Next few months it will be run in a trial operation, when the last parameters will be optimally set. Everything takes place in the suppliers´ - Hydrotech and customers´ - Rajo a.s. cooperation.
Hydrotech participated at the Wastewater 2018 conference in the High Tatras
As wastewater and water treatment are fields which are constantly changing, three employees from the Slovak part of Hydrotech and our colleague from Czech Hydrotech attended the conference called „Wastewater 2018“ in the Highs Tatras. The aim was to listen and to discuss various topics connected with wastewater treatment (project realization and operation of WWTP, legislation, research, etc.) in Slovakia, Czech Republic and partly abroad. Maintaining relationships with experts and meeting new people from this field was the second important purpose of the journey.
Autumn informal meeting of Hydrotech employees
It seems that autumn teambuilding with roasted lamb and other tasty dishes is going to become a rule in the Slovak company´s headquarters. There was no lack of good quality homemade wine, hence, the village Vinosady is area filled with vineyards. It is obvious that the company takes care in sustaining of the community spirit at the workplace and creates enough space for informal conversations without business topics. Such an afternoon can never be useless.
Participation at ECWATECH 2018 in Moscow
The Russian Federation is one of the countries where Hydrotech has implemented several projects and others are going to be implemented. Therefore, we have spent several days in Moscow at the international exhibition ECWATECH 2018. Our employees met some well-known customers and discussed with many others who expressed an interest in being informed, consulting or just having an interesting talk about wastewater treatment.
Export of material for the implementation of the freshest project in Russia
Slowly we are getting to the point of assembling the technology of one of our freshest projects in the Russian Federation. Our company´s venue in Vinosady, Slovakia is full of finished or under-construction tanks, electrical switchboards and even imported machinery. Everything is being prepared for export and a long way to the east.
How to become a guru in work with Microsoft Excel
In order to improve the quality and efficiency of our employees' work, two-day training was organized on working with Microsoft Excel, led by a professional trainer. Many employees commended the level, flexibility and practicality of the course. In the near future, we expect another identical training for employees who did not attend the first course.
Sludge dewatering process optimization at our customer with help of our technologists
The main objective of the wastewater treatment plant at the factory for the production of baking additives, confectionery, dairy products and others was to solve the deficient dewatering of excess sludge originating in the flotation unit and in the biological system. After our visit the dewatered sludge was not liquid but had a consistency of a paste. The quality of centrifuged water on the centrifuge - fugate has also improved.
Meeting of Slovak and Russian Hydrotechs in Vinosady
At the beginning of July, we organized a meeting of Slovak and Russian colleagues in Vinosady. The meeting aimed to exchange experience from project implementation in the Russian Federation. At the meeting, besides technical details, topics related to the organization of export, construction and assembly were also discussed. We will organize this meeting regularly. We believe that we will move on to more efficient and higher quality services for our customers.
After a few months, we finished work with a small scale model of high-load anaerobic IC reactor. In the assignment, the customer asked us to investigate the possibility of wastewater treatment in an anaerobic way for the emerging American distillery. It has been confirmed that the water from this production is a good substrate and the treatment efficiency is around 90%. Our company is interested in whether and how the implementation of this project will advance.
Several colleagues from our design department traveled to the Russian Federation. One group to visit customers in Volgograd, where Hydrotech will realize one of the largest and most sophisticated industrial wastewater treatment plants in its history. The second part of the colleagues went to the town of Kozhevnikovo for a local brewery where the membrane filter modules (MBR system) were also installed.
Meeting of all HYDROTECH directors
After a long time, a meeting of all the directors of the HYDROTECH Group was held. Meeting took place at Hotel Zochova Chata in Slovakia. At the meeting, we welcomed the HYDROTECH directors from Russia, Latvia, the Czech Republic, Slovakia and Poland. Meetings were also attended by the President of the Group Mr. Ioannis Hadjivassilis and members of the Board of Directors HYDROTECH, a.s. - Mr Dušan Vančo and Mr Chrysanthos Mavrommatis.
Czecho-Slovak HYDROTECH meeting
Even after a long break, we managed to organize a meeting of our and Czech colleagues. This time the organization of the meeting was in the hands of Slovak Hydrotech, so we organized the meeting in the royal town of Skalica near the Slovak-Czech border. After a tour of the town and the production of the traditional pastry called Skalický trdelník we have followed a cultural program with wine tasting. Despite the rainy weather, the meeting was rated very well. We are looking forward to the next meeting in the Czech Republic.
New organic mowers
After a successful last year's breeding of a small group of lambs, we started again this year. For a few weeks a small herd passes behind our warehouse and lab. In addition to many other benefits, these animals bring finely mowed lawn. With a slight imagination it then reminds us the lawns in Versailles gardens.
