Municipal waste water treatment plants
for 60 - 180 EI
Supplies
The treatment plants comprise type-specific polypropylene plastic reservoirs intended for installation into a trench to a foundation plate with consequent concrete encasement.
They are made in three type series:
- WWTP AČB E – classic flow activation WWTP
- WWTP AČB SBR - sequencing batch reactors
- WWTP Biofluid EW – activation WWTP with rotating biodisks
WWTP AČB E 80 - 180
Function description
WWTP AČB E 80 to 180 are manufactured in a type range of 3 sizes. Each of them comprises a compact PP container divided, by dividing walls, into the separate functional areas - sedimentation and accumulation area for partial anaerobic sludge stabilization, fully aerated activation part and final sedimentation zone for the separation of treated waste water and activated sludge. To provide for functionality of the WWTP, the separate zones are equipped with air lift pumps controlled by electromagnetic valves. The pressure air sources are Roots blowers. The plant operation is controlled by relays.
The basic AČB E unit may be complemented by tertiary cleaning and/or another technological unit. The treatment plant may be converted into a nitrification-denitrification plant, eventually with chemical precipitation of insoluble solids and phosphorus.
Advantages of WWTP AČB E 80 to 180:
- Classic flow WWTP with aeration for versatile use
- Long service life of the reservoir and technological equipment of the WWTP
- High efficiency of removal of organics, event. nutrients
- Low noisiness
- Automatic operation
- Low cost of acquisition and operation

WWTP AČB SBR 80 - 180
Function description
WWTP AČB SBR 80 to 180 - they are made in a type range of 3 sizes. AČB SBR work on the principle of low-rate activation with sequential batch reactor where the same reservoir (reactor) is used for both activation and sedimentation of suspended solids. The basic version of the plant consists of a polypropylene reservoir divided into the sedimentation and activation parts. The sedimentation part serves at the same time as an accumulation collector and a collector for partial anaerobic sludge stabilization. The separate phases of the treatment process (filling with aeration, sedimentation, removal of treated water and excess sludge) are connected in cycles in the activation part - the reactor. Treatment plant AČB SBR may also be designed as a WWTP with nitrification and denitrification. It is also possible to install chemical precipitation of phosphorus. The basic version of the treatment plant is controlled by a simple programmable relay.
Advantages of WWTP AČB SBR 80 to 180:
- The best-fit solution for irregular (seasonal) inlet of waste water into the WWTP
- Ideal solution to the redevelopment of existing WWTPs
- Optimal solution if step by step connection of the WWTP units is necessary
- Simple installation
- Low energy demand
- Modern technology with high efficiency of removal of organics, event. nutrients
- Automatic operation
- Low cost of acquisition and operation

WWTP Biofluid EW 60 - 80
WWTP Biofluid EW 60 to 80 – they are made in a type range of 3 sizes, each of them in 3 modifications:
- BF EW-N – biocontactor with increased ox. capacity (adaptation to a nitrification unit)
- BF EW-DN – WWTP BF EW-N is complemented with an anoxic biofilter (adaptation to a denitrification-nitrification unit)
- BF EW-DNK – WWTP BF EW-DN is complemented with coagulating-flocculating unit (adaptation to a denitrification-nitrification unit with chemical precipitation of suspended solids and phosphorus)
WWTP Biofluid EW is designed as a compact unit. Its basic part is a watertight plastic reservoir with a technological building-in. Dividing walls divide the reservoir into a sedimentation zone (in variants DN and DNK with anoxic biofilters), final sedimentation area with an overflow discharge trough, and a biological reactor area with a biocontactor with drive in its upper part. To reduce the content of phosphorus, insoluble matters, etc., ferrous coagulant is dosed into the recirculation flow of BF EW-DNK plants.
Advantages of WWTP BIOFLUID EW 60 to 80:
- Low cost of acquisition and operation
- Minimal operating requirements
- High efficiency of treatment
- Reliable operation
- Simple installation and building-in
- It is possible to interrupt the input of waste-water for up to 60 days (the treatment plant is in operation), then it is possible to re-establish full WWTP loading without worsening the discharge parameters.
