The sophisticated design of PURITAINER-wastewater treatment plants ensures that the cleaning performance is very high regardless of smaller power ratings and the often adverse operating conditions. The treated wastewater can be easily discharged into rivers, lakes and others. The PURITAINER-wastewater treatment plant of BIOGEST are produced of corrosion-resistant steel. This durable material has proven useful in more than 200 applications. The dimensioning of the PURITAINER is based on the German guidelines of the “DWA – Deutsche Vereinigung für Wasserwirtschaft, Abwasser und Abfall e.V.”.

The PURITAINER primarily consists of a 40“ open-top container with standardized ISO-dimensions for an easy transportation. The container has a dividing wall for the realization of a inlet buffer tank and a SBR-reactor. The PURITAINER is a nearly ready-for-use system, that means all technical components are pre-assembled inside the container. So before the start-up it is only necessary to establish the connection for the power supply and also for the inlet and outlet pipe.

• Rapid delivery through use of system components
• Easy transportation by container construction method
• ready-to-delivery through complete pre-assembly
• robust and proven technology
• simple operation
• fully automatic plant operation
• repeated use of mobile applications
• consistently high cleaning performance

BIOGEST adapter technology is used to protect retention basins from flooding using an emergency overflow. It provides specific advantages for wall-mounting of flow regulators and enables an emergency draining function in addition to emergency relief with only one outflow opening. This enables the confluence of sewers outside the shaft to be avoided, which means that an additional cleaning shaft is unnecessary.

BIOGEST adapter technology is also extremely suitable for retrofitting to existing structures.

• Flexible fitting facilities/sandwich construction
• Emergency draining even with only one outflow opening
• Simple implementation of emergency overflows
• Optimal retrofitting to existing structures
• Savings in shaft construction

In a rainstorm, it’s not just the water quantity which can lead to problems – coarse solids can also be difficult to deal with. Hygiene articles or other waste can result in unwanted pollution, which can even be environmentally damaging, at inflow locations to receiving waterways. Lamella baffles can provide help.

Functional description

The circular lamella baffle, type LTW-R is a baffle system which serves the purpose of effectively retaining floating matter and consists of lamellas counteracting the discharge of solids through their optimum hydraulic arrangement. The arrangement in the separating structure is possible independently of the geometry of the building. For this reason, the lamella baffle can be used on almost all structures. Moreover, the lamella baffle can be retrofitted very easily in existing separating structures on account of the modular construction. Even small access openings are sufficient for the introduction and the subsequent assembly of the individual modules. Regardless of the respective installation the system reflects the guidelines – as described under ATV A 166 and A 111 – and en-

• Simple retrofitting to existing structures
• Attachment possible through even the smallest openings
• Compact construction thanks to modular arrangement
• Operation without external energy
• Low-maintenance

TRADE FAIR FOR CLIMATE CONSEQUENCES, NATURAL HAZARDS, INFRASTRUCTURE AND TOURISM – March 8 to 10, 2012 is the trade fair acqua alta alpina, a forum for Alpine infrastructure, natural hazards and flood protection in the Exhibition Center of Salzburg. Experts, decision makers and interested parties from across Europe will find the ideal platform to controversial topics such as:  Alpine natural hazard, risk an disaster management, flood protection, barrages and dams, infrastructure, safety and technology, climate.

 BIOGEST is with his Partner PWL Anlagentechnik on stand no. 106 in Hall 1. For more information www-acqua-alta-alpina.at

Flow limiters make an important contribution to flood protection by buffering rainwater and forwarding it throttled. The screens are used to remove contaminants from the overflows of storm water sewers and thus serve the purpose of water conservation. Therefore the BIOGEST products provide for a clean environment for the benefit of the city of Sochi and its visitors.
