PRESECO SBR WASTE WATER TREATMENT
The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate under non-steady state conditions. An SBR operates in a true batch mode with aeration and sludge settlement both occurring in the same tank. The major differences between SBR and conventional continuous-flow, activated sludge system is that the SBR tank carries out the functions of equalization aeration and sedimentation in a time sequence rather than in the conventional space sequence of continuous-flow systems. In addition, the SBR system can be designed with the ability to treat a wide range of influent, both in terms of quality and volumes, whereas the continuous system is based upon a fixed influent flowrate. Thus, there is a degree of flexibility associated with working in a time rather than in a space sequence
While there are several configurations of SBRs the a typical SBR consists of 1 equalization tank, 2 reactors and eventually, a post-equalization basin. The reactors work in pair but with shifted phases. For example, while one reactor is in settle/decant mode the other can be in aeration or filling mode.
Preseco offers a wide range of scalable, cost-effective water treatment solutions for both drinking water purification and waste water treatment. Our pre-designed SBR modules are scalable for influent water capicities from 100-200 m3/day up to 3500-4500 m3/day. Our tailored Waste Water Treatment Facilities can accept up to 50,000 m3/day!
COST-EFFECTIVE, FLEXIBLE, INTEGRABLE
“A PENNY SAVED IS A PENNY EARNED...”
Preseco’s Sequencing batch reactors (SBR) are all about savings and being as cost-effective as possible. Preseco SBR offers the same water treatment capacity with less infrastructure and physical space than other methods. Our state-of-the-art equipment is engineered to consume as little energy as possible while maintaining competetive and effective effluent levels. Due to accurate dosing and process flexibility you need less chemicals to achieve the same level treatment. Preseco SBR facilities are highly automated and requires little to no manpower to oversee operations and offers the possibility of remote control.

SBR + ACU INTEGRATED SOLUTION
Excess sludge removed in the decanting stage is a perfect raw material source for Preseco’s ACU Drum Composting Units. Sludge can be pumped automatically from the SBR facilities to the onsite ACU Drum Composting Unit.
COST-EFFECTIVE ALTERNATIVE

SEQUENCING BATCH REACTOR CYCLE PROCESS
(1.) Filling Stage: The raw wastewater is fed into the reactor and starts to mix uniformly with the biomass held in the tank. Chemicals are also added during this stage.
(2.) Aeration/Mixing Stage or React Phase: The biomass starts to consume the substrate under controlled conditions (aerobic, anoxic or anaerobic), which depends on the type of treatment applied. Excess sludge is preferably pumped during this stage.
(3.) Settling stage: Mixing and aeration are stopped and the biomass is allowed to settle from the liquid resulting in a clarified water.
(4.) Decanting Stage: The treated water is withdrawn from the reactor with specific equipment until a set limit is reached.
