Details

Tittle:
Hungarian company offers a continuous flow Sequencing Batch Reactor (SBR) process incorporating the patented "Feed Forward" cycle
Summary:
This new spin-off company from Hungary is offering a unique SBR process for municipal and industrial waste water treatment with enhanced biological phosphorus removal, where no buffer tank is required. This SME is looking for operators, construction companies, engineering offices specialized in waste water treatment. They are open and flexible for technical cooperation, service agreements, or licensing worldwide.
Description:
This spin off company from Hungary is offering a unique SBR process for waste water treatment with enhanced biological phosphorus removal, where no buffer tank is required. It already has more than 25 reference plants in operation.The support team behind the technology has technology designers, chemists, bioengineers, mechanical and electrical engineers who have more than 20 years of experience in both industrial and municipal wastewater. They are available and capable to answer all queries in short notice.

This advanced SBR is a fully automatic, simple to operate, time-based biological treatment system that responds to flow and load variations, is easily expandable and produces a high quality effluent. The processes of biological oxidation, nitrification and liquids/solids separation are achieved continuously in a single tank.

The standard SBR operates on a fill and draw principle. The process of fill, react (biological oxidation, nitrification), settle (solid/liquid separation), and decant (clarification and sludge thickening) occurs sequentially on a cyclical basis. Influent is allowed to flow into the reactor tank(s) during the fill/react cycle only. Additional flow must be diverted from the tank during settling and decanting period. Therefore, conventional SBRs require two or more tanks and/or influent equalization facilities.

On the other hand, their advanced SBR process allows continuous inflow to the tank, even during the settle/decant cycle. By allowing this flow the process eliminates the need for multiple tanks and equalization tanks. It also incorporates an influent feed forward feature which continuously distributes the influent flow mixed with biological sludge to the sludge blanket during the settle and decant phases. This assures that the hydrolyzing carbon content of influent wastewater can meet with the phosphorous accumulating and denitrifying bacteria which are settled in the biomass. This unique feature helps the biological nutrient removal and enhances the process efficiency over any other SBR process currently on the market.

It is applicable for both municipal and industrial wastewater treatment. Can be designed in single or multiple tank variations as a fully automated system that is capable to handle the flow and load variations normally treatment plants are subjected to.

The advanced SBR process applies a hybrid floating type decanter. It has all the advantages of a submerged weir decanter (consistent flow rate, peak handling capability) while retaining the operation simplicity and straightforward build of floating type decanters. It has a very low energy demand and low operating cost. It has a fail-safe emergency overflow operation even during electrical failure.

They are looking for operators, construction companies, engineering firms specialized in designing and building wastewater treatment plants for both the communal and industrial sector. This new design would enable any company on its own territory to have a market advantage over the old designs which are costlier to build and operate.

They are open and flexible enough to any kind of technical cooperation, service agreements, licensing worldwide.
Advantages and Innovations:
This process can have a single or multiple tank design and the fully automated system is capable to handle the flow and load variations normally treatment plants are subjected to.
Advantages:
· Provides equal loading and flow to all tanks, preventing imbalance seen in conventional SBR´s, simplifies operation and process control
· Can be designed to accommodate up to 6 or more times design flow
· Results in smaller tank size and less equipment, reduces construction and operation and maintenance costs
· Eliminates equalization tank, primary and secondary clarifiers and return sludge pumps
· Enables single tank operation for maintenance situations and low flow conditions
The reaction tank is divided into two zones: a relatively small select zone and a main react zone.
Select zone advantages:
· Wastewater mixes with biomass with a very high Food to Biomass ratio that helps eliminating filamentous organisms that hinder settling and effluent quality
· Conditions promote adsorption onto the biomass creating a large floc that settles much better than conventional biomass
· Helps hydrolyzing the influent carbon which is essential for Biological Nutrient Removal
· Creates anaerobic conditions that helps the Biological Phosphorous Removal (release mechanism)
The incorporated feed forward cycle allows distribution of raw waste water mixed with liquor suspended solids from the select zone to the biomass settled in the bottom of the react zone. This assures that the hydrolyzing carbon content of influent waste water can meet with the phosphorous accumulating and denitrifying bacteria which are settled in the biomass enabling complete biological nutrient removal.
The company has developed its own hybrid floating decanter with unique features:
· Reliable, low operating costs
· Safety overflow function, even during electrical failure
· Easy maintenance (all units accessible from walkway)
· Easy automation with simple control options
· Rugged, corrosion res
