KLEIN ABWASSER-UND SCHLAMMTECHNIK GMBH

About Us

Klein provides machines and plants for a large number of applications throughout the world. The most important fields are separation and recycling processes as well as volume reduction by taking advantage of waste heat as an energy source. The basis of Kleins success is a dynamic and professional team with a knowledge and experience of more than 400 years overall. Through competent sales partners worldwide Klein is always in close contact with the customers to meet their specific requirements.

Kleins aim is not only to follow the state of the art - it is to define it. The machines are constantly updated and improved. It is the best available technique - the technical solution with the great effect each customer expects.

Klein machines and plants are suitable for almost every industrial process for the recycling of valuable materials or for waste processing. Each machine or plant is designed according to the specific requirements and the particular application. By the different process stages of thickening, dewatering and drying, suspensions with a solid capture rate of more than 99 % can be concentrated to a residual product with > 10 % DS. After drying, these materials form an attractive combustible material due to their high organic percentage. Options for utilisation like combustion or gasification may be considered.

All the equipment is produced and preassembled in Germany. Every machine is mounted carefully by hand and leaves the factory only after several performance tests. The installation of the technology is supervised worldwide by Kleins specialists, including the after sales service and consulting support.

The idea of "full service“ is an essential part of the Klein-philosophy. For every machine a personalized and professional 24-hours service is offered

Kleins technology ensures an optimal production process. Installations all over the world prove the fact of its reliability.

Thickening with Belt Thickener BGT

The belt thickener BGT has been developed for a high efficiency solid/liquid separation of suspended particles. Belt thickeners can be used in many industrial processes. The products of a thickening process are a liquid phase (filtrate) being nearly free of particles, and a solid phase, which is pre-dewatered and reduced in volume. The compact machines are easy to maintain, ensure a fully automatic, low wear and low noise operation and are able to achieve solids capture rates of > 99 %.

Advantages and characteristics of the belt thickener BGT

• Sturdy and compact construction in stainless steel quality, on request enclosed
• Low space requirement
• Low investment and operation costs
• Reliable, safe and fully automatic operation
• Very easy to operate and maintain
• Low-wear and low-noise mode of working due to slow run of the machine
• Low water consumption due to the use of filtrate for belt cleaning
• Low polymer consumption due to a careful thickening
• High filtrate quality due to a high capture rate of more than 98 %

Dewatering with Belt Filter Press SNP

The belt filter press type SNP is a continuously operating machine, for the high dewatering of suspensions and sludges. Sludges are carried between two sieve belts along 12 (up to 14) press rollers. The diameter of the press rollers is reduced constantly which results in an increasing pressure. An essential advantage of the belt filter press compared to other dewatering processes is the possibility to enlarge the capacity for high throughput by extending the predewatering zone of the belt filter press (e.g. by installing a belt thickener on top of the press).

The belt filter press can be used in the following industrial sectors:

• Municipal plants
• Pulp and paper industry
• Leather industry
• Textile processing
• Fruit and vegetable processing
• Drinking water processing
• Steel works and roller mills
• Sugar industry
• Bio-water processing

Advantages and characteristics of the belt filter press SNP

• Modern high-capacity belt-filter presses in sturdy frame and open construction completely enclosed
• Large gravity thickening area for predewatering
• High pressure zone includes 12 (or 10) press rollers
 high dewatering performance due to an convenient arrangement of the rollers and high pressing power of 8 - 10 bar
• Low costs for operation and maintenance
• Wash water consumption can be substituted by filtrate
• Low-wear and low-noise operation mode due to the slow run of the machine
• Continuous and fully automatic operation
• High reduction of sludge volume for saving of transport costs
• Sludge cake is suitable for further processes (drying, transport, storage etc.) due to its crumbly, non-sticky structure
• Corrosion-protection due to stainless steel construction, special coatings or hot-galvanized steel

Drying with Belt Dryer Pro-Dry

The belt dryer type Pro-Dry® is suitable for numerous fields of application and has been developed for the drying of moist materials, dewatered sludges and heat-sensitive products from industrial processes and wastewater treatment. Partial drying up to a residual moisture between 30 and <10 % is also possible.

Typically, the dryer and the entire ventilation part are designed in stainless steel to ensure adequate corrosion protection and therefore durability. The belt dryers are designed in modules, so extension can be considered at a later stage.

Special features of the belt dryer are the low operation and maintenance costs due to the comparatively simple process technology. The manpower requirements for the plant are considerably low and the plant is designed to operate fully automatical for 24 hours per day.

An interesting aspect is the use of low-temperature waste heat generated by different processes as energy sources for the drying process.

The pre-heating of the drying air can be performed with waste heat, warm water, warm exhaust gases or low-pressure steam as well as with biogas, natural gas, oil or what ever is available.

A typical energy source is for example the usage of warm water by means of heat exchangers, with temperature of approx. 80° C. Warm water results e.g. from the motor cooling system of a CHP.

Due to the careful drying process with temperatures below 100 °C and without any mechanical stress applied on the material to be dried, explosion or fire protection to a very high standard is achieved by very simple means.

Odour emissions and pollution of waste air or water can be held far below required limit values.

Advantages and characteristics of the belt dryer Pro-Dry:

• Low energy consumption,
• Use of waste heat (e. g. of a CHP-engine) as energy source,
• Safe and reliable operation,
• No odour or emissions,
• No observation or maintenance,
• Dried product hygienisized and free of dust,
• From turnkey plants to units for optimizing existing processes

Utilisation

The dried material with min. 90 % DS is easy storable, abrasion proof and nearly dust free. The calorific value of dried sewage sludge is comparable to brown coal. Thereby the granulate is very suitable for further utilisation - for example incineration or gasification.
