LIQUID WASTE TREATMENT & RECYCLE
Advanced aerobic technology  produces treated water that is continuously of highest quality, allowing for safe effluent discharge and stable process performance.  Anaerobic technologies with high removal efficiency of organic matter, are particularly suited to treat highly concentrated waste waters such as from brewery, distillery, tannery, paper, fermentation and pharma industries.  Waste water recycle technologies include advanced membrane processes such as the membrane bio-reactor which produces an effluent that is extremely pure and appropriate for immediate reuse, as well as the fluidised media reactor and packaged sewage treatment systems.

LUCAS® Aerobic
LUCAS®  Aerobic combines the advantages of  the conventional and the sequencing batch reactor technology.  Like in the conventional system, the reactor volume and the level in the tanks is always constant.  It is a continuous system for both influent feed and effluent discharge.  Like in the fill-and-draw system, the reactor operates according to a time-controlled process cycle that allows for the alternation of all essential processes in a single compartment.   By using the most advanced processes in combination with the autonomous monitoring and controlling system, the treated water will be continuously of the highest quality.  This allows for safe effluent discharge and stable process performance. No external clarifiers, sludge rakers, recycle pumps/screws/piping are needed and reactor volume is always used for 100%.  In addition the system can be easily controlled and the treatment efficiency is very high (80 – 95%).

LUCAS® Anaerobic

LUCAS® Anaerobic is the brand name for an anaerobic waste water treatment system which uses  Upflow Anaerobic Sludge Blanket, Upflow Anaerobic Contact, Anaerobic Filtration and Hybrid Anaerobic Filtration technologies for treating waste water depending on specific requirement. The LUCAS® Anaerobic technology is typically applied as a first stage to remove on an average 85% of the COD (Chemical Oxygen Demand) out of the water. This technology is particularly suited to treat highly concentrated wastewaters rich in carbohydrates and carboxylic acids such as brewery waste waters and waste waters derived from the soft drink and malthouse industry. Depending on the characteristics of the brewery or soft drink wastewater, a high removal efficiency of the organic matter of 70-90% is achieved.

  • UAC (Upflow Anaerobic Contact Process)
    The Upflow Anaerobic contact reactor (UAC) was one of the first reactor types for anaerobic wastewater treatment. It is a simple concept using the CSTR principle. The organic loading rates achievable is 5Kg COD/ m3 per day but however higher loading rates could be designed based on specific characteristics of waste.
    UAC

  • UASB (Upflow Anaerobic Sludge Blanket Process)
    The Upflow Anaerobic Sludge Blanket reactor (UASB) was a successful improvement for anaerobic wastewater treatment. High volumetric loading rates up to 15 Kg COD/ m3 per day can be reached depending on the characteristics of waste water.
    UASB
  • AF (Anaerobic Filter)
    Bio-filtration uses bacterial immobilisation by means of slime films on an inert support material and entrapment of sludge flocs with in the macro-porous structure of the carrier material. The reactor loading rates could be upto 10 Kg COD/ m3 per day depending on waste characteristics.
  • Hybrid
    Hybrid reactors are recent development utilizing the benefits of UASB with AF or with UAC. The Hybrid design has advantages of UASB and operation flexibility of UAC or AF.

Based on the effluent limits that have to be met, the LUCAS® Anaerobic stage can be followed by a LUCAS® Aerobic stage to remove the remaining COD and to remove nutrients (N&P). The  LUCAS® Anaerobic-Aerobic, where the anaerobic stage is followed by an aerobic stage,  has been  specifically developed to meet the needs of breweries and beverage companies.  Both stages can be applied separately or in combination. 

Advantages of  LUCAS® Anaerobic-Aerobic with Nutrient Removal

  • Uses Upflow Anaerobic Sludge Blanket (UASB) technology
  • High COD removal efficiency (upto 90%) in UASB reactor
  • High biogas production – can be converted into heat and/or electricity (0.3-0.4 Nm3 biogas/kg COD)
  • Low sludge production (0.02 kg SS/kg COD converted)
  • Robust and proven technology
  • Very compact design
  • High effluent quality with complete nutrient (N&P) removal
Membrane Bioreactors For Compact Waste Water Treatment & Recycle
Ion Exchange Waterleau Ltd. offers two different membrane bioreactor concepts to produce an effluent that is extremely pure and appropriate for immediate reuse. Micro and ultra filtration membranes can be used for the separation of sludge and biologically purified waste water. By replacing the sedimentation step by membrane separation it is possible to operate the bioreactor at much higher concentrations, thereby reducing the volume of the bioreactor drastically.  An extra advantage of the fact that the filtrate is virtually free from suspended solids and bacteria since these cannot pass the membranes.  The filtrate will thus be ready for reuse or for further treatment by reverse osmosis.  Two membrane bioreactor concepts are possible depending on the choice either to submerge the membranes into the bioreactor or place these membranes in an external loop. 
  • Single packaged unit with minimal civil construction – minimum land usage
  • Modular in construction and design
  • Compact – requires ½ - 1/3 space of conventional system
  • Low energy consumption (0.30 kwh/m3) for submerged filtration
  • Upto 6 log (99.999%) removal of total coliform
  • No chemicals required during treatment
  • Low operating cos
Ideal for Housing complexes * Townships * Hotels * Golf & Country Clubs * Industrial Estates * Existing Plant Upgradation

Submerged Membrane Bioreactor


With the INDION Submerged Membrane Bioreactor, the higher biomass concentrations can be kept in a reactor causing a decrease of the bioreactor volume with a factor 3-4 compared to a conventional sludge system. Furthermore, the energy consumption is kept to minimum by placing the hollow fibre membranes inside the reactor.

X-TRACTOR Crossflow Membrane Bioreactor
xtractor
In the X-TRACTOR Crossflow Membrane Bioreactor, tubular membranes are placed outside in an external loop of the bioreactor. Due to the high-energy consumption, caused by the high-speed circulation, this crossflow concept is  used to treat smaller but more difficult waste water flows.
