Optimized plant operation trough separation
The XSplit press screw separator in the biogas plant

Separation with the XSplit opens up economic solutions to increase the efficiency of a biogas plant or to avoid operational malfunctions and component failures. If, for example, increased proportions of long-fiber solids such as manure, corn straw or landscape conservation material are fed as a result of a substrate change, this leads to an increase in the viscosity of the suspension. Pumps and agitators consume more power. At the same time, they contain a high proportion of lignin and semi-cellulose, for the degradation of which the residence time is often too short. The specific gas yield decreases.

Separation with the XSplit can remedy this and generate further benefits. If the solids are separated from the suspension, they can then be fed back into the fermenter. In this way, the residence time is extended, a higher proportion of organic matter can be converted into biogas, and the gas yield increases.

If the digestate is separated, the liquid phase, which makes up a significant proportion, can be passed back into the fermenter. This reduces the viscosity of the suspension, and the power consumption of pumps and agitators drops.

The solids previously separated from the digestate can be stored separately and can be transported more efficiently. At the same time, less storage capacity needs to be kept available for liquid digestate.

And the separation of the digestate has further advantages. As with slurry, fertilization with digestate can be adjusted accordingly. The liquid phase, in particular, is very suitable for fertilizing grassland, as the digestate penetrates the soil more quickly thanks to their increased flowability.

Features of the XSplit

The inlet nozzle, like the filtrate nozzle, can be rotated in 90° increments and can be mounted both at the top and at the bottom in a connector size of 6". This allows flexible adaptation to the respective situation on site.

The screw of the XSplit press screw separator is made of stainless steel and specially armored for extra durability. Fiber pockets are integrated for self-cleaning.

The wear-resistant elastomer closure disc ensures automatic plug formation without the use of additional auxiliary agents.

The drive motor is located on the solid side and thus has no contact with the liquid during the separation. The conveying and separation direction is towards the drive. Therefore, the XSplit does not require an extra mechanical seal or radial shaft seal.

The length of the pressing area can be adjusted by means of a threaded spindle. A longer pressing area means higher dry matter content of the solid phase.

The sieve basket of the XSplit separator consists of three sieve elements. These are individually replaceable and enable optimum service performance and individual adaptation to the output medium.

The generous end cover provides easy access to the sieve and screw. In addition, four 6" cleaning ports provide good access to the interior of the XSplit. Service and maintenance work is completed quickly.

Options of the XSplit

With the stud frame, the XSplit is easily and quickly elevated. Pumps and, if necessary, a shredder can also be assembled on the base frame, so that the installation effort on site is reduced.

Compact unit including pump, optional shredder and the XSplit separator, which is folded out and positioned in an elevated position by means of hydraulics. Completely pre-assembled including static calculation, the basic hoisting gear is the ideal solution for changing locations.

Drive up, set up, connect, get started. Assembled on a trailer, the hoisting gear pro complete solution is the flexible variant for inter-company use. All components including hydraulics are fully assembled and connected to the controller. A generously dimensioned projection and ejection height make it possible, for example, to separate directly on high trailers.

Depending on the customer's requirements, we offer the necessary control technology for manual operation of the individual components up to control with touch panel and intuitive user interface.
