Waste water treatment facility

A major manufacturer of human waste facilities specialized in the intake of waste water from areas which are not connected by a sewer system. The waste water is delivered in tanker vehicles and often contains solids and fibers. Previously, the solids were separated from waste water by grids. However, blockages kept occurring from the solids, causing more maintenance work. The solids also had to be disposed of separately which presented an additional cost. The operator then decided to chop the solids when waste water entered the system. By chopping the solids, a higher gas yield could be achieved in the digestion towers as well as having an overall positive biological impact. 

The customer chose a Börger Multicrusher to do this, due to very limited space restrictions in the standardized human waste facility, the Multicrusher had to be very compact. It was decided to run the Multicrusher with a helical bevel geared motor with direct coupling.

This had the benefit of being easily maintained. The Multicrusher was also fitted with a rock trap. To avoid any obstinate solids from blocking the chopper, the Multicrusher has reversing control. 

The operator of the facility is highly satisfied with the Börger Multicrusher.
