Design and construction/reconstruction of different size and type WWTP
When type in “Google” search system “waste water treatment” you may find a lot of different so-called “unique treatment technologies”, that can be applicable for almost every WWTP, starting from private households and up to town or city municipal WWTP. But actually it is the myth, created by small size WWTP producers, while advertising their products. Municipal wastewater treatment is the sequence of mechanical, physical and biochemical processes, which should carefully calculated in order to achieve effluent requirements with maximum reliability and minimal operational costs. There is no any universal technology, that covers all treatment steps. Every treatment chain should be calculated very carefully, different technological process or solution should be chosen, according influent and effluent concentrations and flows.
The majority of our staff have studied in Vilnius Gedimino Technical University, environmental engineering faculty and have been graduated for Master’s degree. Water management director Regimantas Dauknys is a doctor of technical sciences in water management. Every our WWTP is carefully designed and best solutions are chosen. Biological wastewater treatment processes are calculated according standard ATV-DVWK-A 131E, and also based on knowledge and know-how of UAB «Arginta» professionals.
The “heart” of the municipal wastewater treatment is biological treatment chain. All technological process before and after biological treatment will influent it results and should be chosen to ensure proper organics/nitrogen/phosphorus ratio. Because biological treatment is just sequence of chemical degradation reactions produced by different active sludge microorganisms and bacteria during their life circle, differences in treatment technology are nothing else but creation conditions for proper BOD/N/P ratio. Depending on the influent, few different biological treatment schemes can be applied.
