소화조 교반기

The Gravity-Belt-Thickener is a high-quality, well-engineered and efficiency working system that actives an above-average volume reduction in the solids/liquid separation of sludge and other suspensions from waste water treatment.


- Sturdy and compact design in stainless sell quality, on request encapsuled
- Reliable, safe and fully automatic operation
- Low water consumption by use of filtrate for belt cleaning
- Low-wear and low-noise mode of working because of slow operation speed
- Low polymer consumption by careful thickening
- High filtrate quality results in a high capture rate of more than 98%
- Outside installation possible
- Low space requirement
- Low investment and operation costs


- Drinking water treatment plants
- Breweries/beverage industry
- Leakage processing
- Pulp and paper industry
- Recycling of animal cadavers, slaugh-terhouses
- Dairies and food industry

The products of klein Technical Solutions are designed for treatment of suspensions and pre-dewatered products that are usually waste or difficult waste materials. Therefore, the prior aim is to reduce the volume of these materials as much as possible in order to minimize the waste disposal costs. The different processes, as thickening, de-watering and drying, enable a concentration of suspensions with a water content of more than 99% to a residual product with a water content of <10% Based on the high organic percentage of the suspensions the dried material forms an attractive combustible. The dried granulate is hygienised, almost dust-free and easily storable. Drying of sludge and other suspensions also enables further utilisation possibilities, like combustion or gasification. In some cases the use as fertilizer may be possible as well.

The advantages

- Low energy consumption
- Low energy costs by usage of waste heat
- Standard heat sources
- Direct heating : raw gas, biogas, Propane/Butane, fuel-oil
- Indirect heating : warm water, process air, thermo-oil, steam
- Waste heat can be used like
- Warm water 90℃
- Process exhaust(90-500℃)
- Other available heat
- Construction acc. ATEX
