What do we do now for precious Earth

Features

・TSKE is enjoying top share in the field.
・Can be reduce the risk of public nuisance.
・The complete decomposition of the organic substances in the liquid waste is achieved regardless of kind or character of the liquid waste.

Features

・Combustion is not applied, requiring no fuel, and exhaust gas does not include NOx, SOx, and dioxins.
・No secondary waste such as excess sludge as in biotreatment is generated. The system is applied to wastewater that is difficult to handle through biotreatment.

Distillation effectively removes low level of VOCs in water, but large amount of steam energy is required. With the BMB stripper, steam energy consumption can be reduced by bringing the gas flow closer to the plug flow.
VOCs in water are removed by conventional aeration by releasing them into the air to prevent water contamination. Distillation method is effective for removing small levels of VOCs in water. However, large amounts of steam and energy are required for conventional methods because reducing the amount of steam causes the downward liquid to mix with the upward steam flow, so concentration becomes vertically uniform to the tower, disabling direction control/countercurrent flow of liquid and gas.
However with the BMB stripper, the gas flows closer to the plug flow, which maintains the vertical concentration difference. The liquid flows down in the tower as it contacts with gas and concentration of organic compounds decreases gradually to less than the permissible level, then discharged from the base of the tower. As steam flows upward, concentration of organic compounds increases, allowing for their recovery and reuse. Use of little steam allows increasing the concentration of organic compounds, so solvent phase and aqueous phase can be separated efficiently with a decanter.

Features

High load and high efficiency
?Organic volumetric loading rate: 50 to 80 kg/m??D
?Organic removal rate: 95% (based on tests with artificial glucose water)

Greatly reduces aerobic biotreatment (activated sludge) volume and eliminates activated-sludge bulking at subsequent stage.

Features

・Effectively reduces organic CODs as pretreatment for activated sludge.
・Reduces the treatment volume of activated sludge and excess sludge generated at the subsequent stage.

Direct Combustion System

・Applies to gas containing much dust or waste gas with high heating value.
・Heat recovery of waste gas containing little salt.

Features

・Sand is circulated at high speed (5m/s) in the furnace where sludge is crushed instantly, and combustion efficiency is increased significantly as compared to the fluidized-bed incineration method.
・The lower section of the furnace is made large enough to process waste wood or plastics that are crushed to the size of about □100.
・Low combustion temperature (850℃) can suppress NOx generation.

Features

・Quick and efficient combustion in a short time, leaving little unburned materials.
・Applicable widely to different types of wastes such as sludge, waste oil, various waste liquids, and animal manure.
・Standard lineup ranges from 10 to 350 ton/day processing.

Features

・Large usable area with no dead surface area (surface not exposed to liquids)
・Low pressure loss with line structure that allows high void rate and decreasing tower diameter
・High liquid dispersion efficiency with curved line structure and many contact points in packing layers
・Lightweight, strong chemical and mechanical properties with synthetic resin
・Ease of filling and extraction using lightweight material
・Ease of removing adhesions

Features

・Smooth gas flow and reduced pressure loss with alternating wave structure
・Liquid film flow with entangled packing, similar to our latest model SPIRAX, resulting in large material transfer (Same effect is confirmed with our product, TELLERETTE.)
・Flooding at joints prevented with “Semi Structured Packing”
・Support rings do not have to be completely removed when remodeling shelf block towers
・However, when remodeling to standard packings, support rings need to be completely removed up to the outer-circumference edge.
・Reduced number of redistributors with homogeneous liquid distribution
・Cost savings with high-speed machines
・RSR is available in SUS as well as materials that are thick or thin such as titan, nickel, and tantalum
・HETP, pressure loss and intensity are far beyond the most efficient random packings
・Verified high performance of RSR by tests in the world-class distillation research institute, FRI (Fractionation Research, Inc.)

Features

・Higher theoretical stage/packed height
・Lower pressure drop/theoretical stage (1-20mmH2O/m)
Higher liquid operating capacity (1-50m3/m2.hr)
・Higher Vapour operating capacity (FV=0.5-3.5√Pa)
