KIS Group is Asia’s Most Successful & world’s leading technology provider for Biogas, water and waste water treatment.
Our most promising ZPHB® technology is for medium to higher organic load effluents. It is a unique design technology operating on either Mesophilic or Thermophilic process designed for effective mixing of raw wastewater for proper degradation by microorganisms and allowing maximum removal efficiency of COD and BOD with consistent results. Control of process is simple and user friendly with automation.
1. Efficiently designed for higher Hydraulic and Solids Retention Time.
2. Complete Homogenization, resulting in higher Methane & Biogas Generation.
3. Higher removal of BOD and COD.
4. Maintenance Free and Less OPEX.
5. Long durability and proven reliability.
ZPHB® - CSTR
The ZPHB®-CSTR is a conventional digester design consisting of an above-ground tank with a fixed MS Roof. ZPHB®-CSTR tanks are manufactured from Special grade MS Plates. The ZPHB®-CSTR utilises the lateral agitator and top entry mixing system to mix the slurry, giving good surface contact between microbes and organic matter, which results into higher biogas production.
Biogas is collected at the top of the digester roof then goes to a gas holder either of Double Membrane type or MS Gas Holder. The slurry overflow from the digester is passed to the ZPHB® clarifier where the separation of biomass takes place, then part of biomass will be recycled back to the system to maintain the F/M ratio. The overflow will be taken to further process.
a. ZPHB® - A : AGITATOR MIXING
The agitators are either fixed to the walls of the reactor or else submersed inside the reactor. Based on the volume of the reactor the number of agitators is fixed and they are continuously stirring the substrate inside the reactor. The power required is very less. These can be installed either in fixed roof or in the membrane roof.
b. ZPHB®- P: PUMP RECIRCULATION
Pumps are provided for mixing of the Reactor to ensure the homogenization of solids inside the reactor. Pump suction is taken from top of tank and recalculated back to bottom of the tank for continuous mixing and scum breaking option is also provided. The number and capacity of the pumps depends on the volume of the reactor. Generally pumps are provided for working and standby.
c. ZPHB®- S: SUBMERSIBLE AGITATORS
The submersible agitators, submersible mixers and slurry mixers are used for the processing of livestock slurry, biogas, and industrial effluents. The propeller rotates and creates liquid flow in the tank, which in turn keeps the solids in suspension. The mixer can be removed periodically for inspection and maintenance.
d. ZPHB® - G: ADVANCED TURBO LIQUID GAS MIX TECHNOLOGY
Advanced Turbo liquid gas mixing technology is an ideal and unique solution for biogas digesters as it generates more biogas. This system is a combination of a pump mixing system and a gas mixing system. The result is a combined horizontal and vertical mixing pattern. The vertical mixing pattern is caused by the rising sludge gas bubbles. Powerful mixing performance is ensured in all areas of the tank through bottom and top Nozzles arrangements. Gas Mix pump operation is intermittent.
ZPHB®- U
ZPHB®– U reactor consists of mainly feed distribution network at the bottom from Distribution Box. Sludge blanket is formed at approx. mid height of reactor and the gas, liquid, solid separator (GLSS) at the top of the reactor. In ZPHB®–U process the bacteria responsible for digestion process are present in the form of sludge blanket. The bacteria grow and reside as bacterial flocks suspended in the up flow effluent stream. The bacteria take the organic content of wastewater to metabolize it and produce biogas and biomass. The anaerobically digested effluent is collected from the network of gutters and launders and part of treated effluent will be recycled back to buffer tank for hydrolysis.
ZPHB® - IC
IC reactor consists of mainly feed distribution network at the bottom, Sludge blanket at approx. mid height of reactor and the gas, liquid, solid separator at the top of the reactor. The bacteria grow and reside as bacterial flocs suspended in the up-flow effluent stream. This is widely used for high organic waste water treatment and Organic Loading rate can be upto 30kgCOD/m3/day.
ZPHB® – REACTOR CONSTRUCTION
We select the suitable reactor construction materials based on site conditions, location and CAPEX of the project. We provide RCC construction, MS Plate fabrication at Site and Bolted Tanks Glass fused tanks for the reactor. Roof is either Fixed MS or Double membrane type as per suitability. External Gas Holder will be RCC with MS tank or Complete MS Tank or Complete Double membrane type gas holder or RCC with Double membrane top.
ZPHB® – BIOGAS APPLICATIONS
The generated biogas from the reactor will be utilized in Biomass Boiler for heating, Biogas Engine for Power Generation and Biogas Upgradation for Bottling of Bio-methane for Domestic, Industrial & as a fuel for vehicle.
