Sewage Water Treatment
Physio-Chemical Treatment
Physio-Chemical treatment constitute a single stage in waste water treatment with coagulation and flocculation methodology. The type of treatment selection depends on the size of the particles present in the waste water.
It provides a range of optimised solutions extending from water softening to almost nutrient removal process.
Biological Treatment
According to the customer needs, the biological waste water treatment provides optimum solution to the problem faced in the waste water treatment system.
Activated Sludge Process
It is a conventional methodology of waste water treatment as standard solutions for average to high purification requirements.
The Process
The Activated Sludge Process (ASP) is a sewage treatment process in which air is blown into raw, unsettled sewage to smash the solid content and develop the biological growth in the system. It involves the phase in which the water to be purified is brought into contact with a bacterial floc in the aeration system followed by clarification tank with high rate of recirculation rate in the system while the excess sludge goes into sludge treatment line.
Advantages:
- Odourless
- Very reliable
- Simple process
- Cost effective
- They re-seed themselves with beneficial bacteria.
Membrane Bio Reactor
Cermosis membrane bio reactor technologies utilise both anaerobic and aerobic waste water treatment processes that combine jet and slot aeration with membrane bioreactor technology to achieve robust, compact and cost effective treatment plants. The plant is fully automatic controlled with its unique control philosophy.
Markets Served:
Industrial small scale, large scale, commercial facilities, food, beverage and dairy industry.
MBR Service:
Project Management, process design, pilot plant testing, build, install and operate, startupsevices and commissioning, revamping the conventional methodology, trouble shooting, operation and maintenance.
MBR Technology:
The low energy design of membrane bioreactor utilises intermittent backflushing for the control of membrane fouling which allows a reduction in dead end and cross flow by saving a energy in the system. This process can be aimed to use for sewage treatment waste water with tertiary polishing prior to RO reuse. The energy optimised here with the use of VFD controlled recirculation pumps the system allows for variable flux rates with high permeate volume. This plant is particularly suitable for application with variable waste water flows, high peak or seasonal loads.
Technology Special Feature:
The membrane modules are considered with two types of membranes such as flat sheet membrane and hollow fiber membrane. The membrane module will be placed inside the bio reactor with the aeration control strategy applied. It is ease of maintenance and immersed in the biomass. It offers low energy costs and super flexibility of process operation.
- It can be operated at high solids concentration and new low footprint treatment tank can be installed.
- At average flow conditions, the membrane system is designed to fully optimize energy consumption and can ramp up to deal with peak flow conditions with variable flow rate.
- No additional membrane is required to treat the high solid content in the reactor.
- It provides high flux rate with minimal fouling o
- No ‘back flushing’ system is lost from the system and is returned to the upstream process.
Ceramic Based Membrae Bio Reactor
MBR-Ceramic membrane
We offer the ceramic technology with the design and development of membrane feature of durability and there by a long lifetime which is expected to exceed more than 10 years.
It has following advantages:
- No long back wash time is required
- No relaxation time
- Cannot be degraded by temperature, oil or chemicals
- No fouling effect on membrane
- MLSS loading up to 20,000 ppm without clogging in the reactor
Sequential Batch Reactor:
The sequential batch reactor process (SBR) involves a single complete mix type reactor in which aeration takes place followed by clarification when the designation is sequential. Sludge settles when aeration is shut down (automatically) and the drainage mechanism used to draw off the supernatant with constituting cycle.
The five sequences of the process are:
- Feed water inlet
- Reaction tank (aeration/mixing in the tank)
- Settle it down
- Transfer of supernatant
- Extracting the sludge
The extracted sludge can be eradicated at the end of the drainage period. The total cycle fluctuate between 4 to 12 hours according to the influent concentration and exclusively to eliminate the carbon and nitrogen and even phosphorous.
The Advantages of using SBR:
- Sequential process flow by with less recirculation rate
- Flow rate tolerance and polluting load variations
- Very good clarification conditions
- Simple and compact construction
In this type of system, both conventional methodology and single stage batch reactor system are adopted with which batch system with one single tank, effluent feed and discharge will be intermittent.
Nitrogen Removal Treatment-Nitrification & DE-nitrification
The process can be used for the treatment of raw waste water from urban areas and the pre-treatment of industrial waste water.
A hybrid solution integrating the fixed film process by combined cultures equipment developed for the removal of nitrogen and carbon. It is a combined process of bio filtration and suspended growth technology.
Nitrification potential is higher than activated sludge process.
Advantages:
- Compact structure
- Flexibility (strong load variations during peak period)
- Good effluent quality
- Easy to operate
- High level of automation/system reliability
- Ease of integration within existing plants
