A Global SBR DevelopmentThrough Leading-edge Engineering

For an SBR process to surpass the performance and relia bility of other biological processes on the market, the SBR design integrator must perform on-going research and deve lopment while maste ring the latest developments in microbiology, process design, hydraulics and automation.

Each concept is hydraulically tested using in-house simulation software to certify that our design will accept sustained peak flows.

An hydraulic graphical display illustrates sequential operation versus equipment utilization during sustained peak flows.

Four main aspects of SBR

Bio-Design Simulation Platform

At Premier Tech Aqua (PTA), the basic SBR concept has always been a great source of inspiration to our development team. For the last decade, our company has invested in this most promising treatment concept to finally develop an extensive range of various SBR processes. This allows our clients to treat their organically contaminated wastewater.

PTA’s SBR processes were developed using innovative combinations of physical parameters, such as various reactor feed modes, with creative internal baffling. These parameters are then combined with adjusted anoxic, anaerobic, and aerobic periods, to offer a unique site-specific process for each application.

This broad design approach allows PTA to review various SBR process configurations and select the most, practical solution capable of resolving project-specific wastewater treatment conditions in the most economical manner. Finally, EcoprocessTM SBR designs are certified for biological perfor mance using a modern simulation platform. These bio-simulations validate all aspects of the biological treatment system and certify that the required treatment performance will be achieved.

The OxiSequencerTM process has been developed to offer a more convenient solution to customers having to deal with small flow wastewater systems. The OxiSequencerTM makes use of a long solid retention primary settling tank (BioSeparatorTM) followed by a SBR process. In case of high hydraulic variations of the flow, partial equalization can be incorporated ahead of the SBR. Secondary sludge can be returned and stored into the BioSeparatorTM unit.

PRinciPAL APPLicATionSLeachateHigh ammonia and high organic toxic effluent treatment

Through accurate process design and innovative treatment cycle, PTA has developed its Step-feed SBR process capable of treating highly charged landfill leachate effluents while avoiding the bio-toxicity of high ammonia. This particular SBR process consists of a special feed mode coupled with site specific treatment sequence. The system is specially engineered to maintain all necessary biological and chemical balance to provide nitrification and denitrification. This process also allows energy saving and offers high treatment performance without the use of chemicals.

The EcoprocessTM GF-STB SBR makes use of baffled reactors and alternately feeds one at the time with 100% of the flow. This process treats the wastewater in defined batches, allowing for an aerated no-flow period before the treatment cycle is completed. Process description

This no-flow period assures that the last quantity of wastewater entering the reactor will be safely treated before the sequence ends and the treated effluent is discharged.

FeaturesThe GF-STB SBR includes on-line process optimization, full management of all alarms and energy saving attributes.

ApplicationThis SBR configuration is an excellent process for most municipal applications. It requires more elaborate design, more equipment and more sophisticated logic controls. This is ideal for municipal projects where partial bio-P removal is desirable or for treatment of highly concentra ted wastewater (municipal and industrial) where stringent effluent quality is required.

Treatment performanceGF-STB SBR plants treat municipal wastewater to <5 mg/L for both BOD

5 and TSS. It also provides complete nitrification and

significant denitrification. The plant can also achieve bio-P reduction to <0.3 mg/L TP with chemical assistance

The EcoprocessTM CF-ID SBR makes use of baffled reactors continuously fed from an influent splitter box or channel concept. A rectangular reactor configuration is often used to ensure there is no hydraulic short-circuiting. Was te water enters the front end of the reactor while the treated effluent is decanted at the opposite end.

Process descriptionAlthough the front end (pre-zone) of the reactor is mainly for hydraulic control, it also pre-treats the wastewater biologically. Further, it promotes higher performance in many ways. Influent travels from the pre-zone to the main-zone through submerged ports at the bottom of the baffle wall. The influent is already substanti ally treated as both sections of the reactors are aerated. During the fill-decant step, pre-treated wastewater percolates through the settled biomass in the main reactor to promote absorption of the remai ning soluble organics.

FeaturesThe process controls are not as sophisticated as for a CF-ID SBR. They include standard EcoprocessTM SBR features such as on-line process optimization, full alarm management and energy saving attributes.

ApplicationIdeal for municipal applications where secondary treatment may be desirable, such as improved BOD

5 reduction, nitrification and partial

denitrification.

Treatment performanceCF-ID SBR plants treat medium strength municipal wastewater to <5 mg/L BOD

5 and TSS while providing complete nitrification and

substantial denitrification.

4-Reactor Scada Display

Advanced Programmable Logic controllers

PTA features a comprehensive and operator-friendly supervisory control and data acquisition (ScADA) systemPTA is made of a multidisciplinary, experienced team with advanced know ledge in process engineering and control software programming. The team manages all mechanical and electrical aspects of the SBR stations.

Our software programs are the core of our technology. They are developed in-house by our experts and are supported by the same team. Electrical concepts are established within a well defined architecture to assure quality product that can be easily serviced and/or modified.

Most of our SBR stations are provided with our SCADA system. This is a major asset for the client and an immeasu rable tool for the operator. The SCADA system monitors and edits all defined para meters within the plant and is ideal for communications and service liaison with PTA service team. Control panels and SBR software programs are duly tested prior to shipping using a unique program simulator operating in acce le rated mode in order to test the totality of the program. Hence, only minor (if any) adjustments may be required during the start-up period.

Our SBR stations are typically equipped with all necessary software and hardware to enable easy and direct support via the Internet.

As an option, PTA also offers a local/remote operating system. At the heart is a “PLC-Laptop-Beeper-Modem” to increase work efficiency and save operator’s time. This state-of-the-art control system asserts that customers will be fully satisfied with a SBR process designed, supplied, commissioned, and monitored by PTA.

Being an automated process, the EcoprocessTM SBR clearly requires leading-edge programming to operate without failure and to manage all alarms. The station must meet effluent requirements no matter what goes awry in the plant (including equipment and power failure) without requiring a permanent presence or intervention of an ope rator.
