Industrial and sewage / Biofuels
Our industrial sewage treatment plants are supplied to various industries. Specifically for food, automotive, textile, paper / pulp and cellulose, chemical as well as pharmaceutical industry. In addition, we provide sewage treatment plants for the processing of ores and animal waste (rendering plants).
In order to purify concentrated industrial waste water, we successfully apply a solution for anaerobic purification where we also use technology producing significant quantities of biogas. Thanks to this, your WWTP can produce electric or thermal energy. In addition, we can help you with the efficient cleaning of wastewater with high nitrogen, phosphorus or sulfur content.
We have finished so-called pilot tests in which several tens of liters of wastewater from ethanol production were treated daily. Quite complicated wastewater treatment technology was tested. The main part of the treatment plant was a high-load anaerobic reactor using granular sludge and producing energy-rich biogas from the removed pollution. Other monitored parameters in the process were the concentration of hydrogen sulphide in biogas, the efficiency of precipitating high concentrations of phosphorus in wastewater. After the anaerobic stage, the aerobic part of the treatment plant followed, which ensured water purification, elimination of high nitrogen concentrations and water preparation for reuse back in the process.
Project of installing a second settling tank was completed by Hydrotech for our brewing partner in the Czech Republic. Since beer is a popular beverage, the reason of overloading is, of course, increased production capacity, and therefore increased production of wastewater. The second settling tank was equipped with automatic scraping of the tank bottom and tank surface with a collecting vessel for floating impurities. Outlet channel will be installed around the perimeter of the tank with a V-notched overflow and a protective submerged wall to prevent floating impurities to escape into the effluent. In this way, the loading is divided into two sedimentation tanks and the process of sludge and treated water separation is intensified.
Works on the intensification and completion of a wastewater treatment plant for our customer have just begun in recent days. Factory is one of the most important producers of ham and meat specialties on the Czech market. Necessary changes in the wastewater treatment process occurred due to the demand to increase the capacity of the wastewater treatment plant, but also due to stricter requirements for effluent, especially in the nitrogen parameters. The new WWTP will include a flotation unit which will be removing part of the pollution using physical process. Next step will be biological treatment which treats the rest of organic pollution and the majority of nitrogen pollution in a two-stage denitrification-nitrification configuration. In addition, sand filtration is included in the treatment line for water purification to the BAT (Best Available Technology) standards.
Hydrotech specialists guarantee high quality solutions to all kinds of clients across several industries.
Starting with design through construction to completition we have been able to deliver more than 700 wastewater treatment plants across Europe, Asia, Africa and Caribbean.
