Integration of Reclaimed water process equipment using membrane
bioreactor (Membrane Bioreactor, referred MBR] technology is a new
process of biological treatment and membrane separation technology
combined, replacing the traditional process of secondary settling
tanks, which can be efficiently solid-liquid separation to obtain a
stable Reclaimed water directly. but also to maintain a high
concentration of microbial biomass in the biological pool, less
residual sludge process, extremely effective removal of ammonia,
effluent suspended solids and turbidity is close to zero, and the
bacteria in water virus is substantially removed, low energy
consumption, small footprint.
The scope of application
Suitable for residential quarters, office buildings, shopping
malls, hotels, restaurants, offices, schools, military units,
factories, and other sewage and similar industrial organic
wastewater, such as textiles, beer, paper, leather, food, chemical
industry, organic sewage deal with.

Grilling by sewage into the conditioning tank via the lift pump
into the bioreactor, open aerator oxygenation by PLC controller,
the bioreactor by water circulating pump into the membrane
separation unit, dense water return regulation pool, the water
passes through the membrane separation Quick mixing chlorination
(sodium hypochlorite, bleaching powder, chlorine tablets) after
entering Reclaimed water storage tank pool. Backwash pump use treated water for cleaning the pool backwash
membrane process equipment, recoil sewage return regulating pond. Lift pump by opening and closing the water level inside the
bioreactor control. Filtering and backwashing the membrane unit can be Automatic or
manual control. When the membrane unit needs chemical cleaning operation, close the
inlet valve and water recycling valve, open the valve and
pharmaceutical drug wash cycle valve, liquid start circulating
pump, chemical cleaning operations.
The integrated bioreactor programmable logic controller (PLC)
control. It has the following features:
* Membrane bioreactor entire process Automatic control systems,
greatly reducing the cost of operation and management.
When the bioreactor water reaches the high level, the lift pump
stops running, lifting pump Automatic turn on when the water level
falls below the water level.
Reclaimed water storage tank according to water level Automatic
open and close the circulation pump.
Automatic ON, OFF dosing pumps, dosing amount can be adjusted
according to need.
Automatic operation of membrane cleaning and disinfection
Motor with over-current, overload protection.
Has built Reclaimed water reuse project of common treatment is
ineffective, higher operating costs, facility covers an area larger
issues such as treatment facilities are not ideal. Therefore, China's urban Reclaimed water treatment business is an
urgent need to develop cost-effective application of processing
technology and equipment.
