Sleegers Engineering Inc (SEI) has developed a new process adopted from a European model to dewater liquid manure.

By separating as much of the liquid content from the solid suspended manure, virtually all the nuisance factors are said to be eliminated. The two remaining components are water and compostable manure. The first is useful as an irrigation source for times when rain is not plentiful. The second component becomes a valuable cash commodity.

The SEI dewatering press separates 95 percent of the suspended solids from the liquid manure, thus ensuring the fluid portion is ideal for irrigation since as little as 0.5 percent of the solid matter remains.

The company says the ideal solution is to separate the solids from the liquid since it is the mixture of the water with the constituent solids which creates an environment for fermentation and unwanted bacterial growth.

The SEI dewatering system is designed to do just this. The liquid manure is pumped into a cylindrical screen. Inside this screen is an auger. As the manure is pushed towards the discharged end by the auger, it is subjected to gradually increasing pressure. In essence, it squeezes the fluids from the suspended solids in much the same way as you would squeeze water from a sponge. The remaining dewatered solids are pushed out the discharge end of the screen. The water drains by gravity into a pan where it may be further filtered by a fine screen, which strains any residual solids. The filtered water is then pumped into another holding structure for further use as irrigation or returned in flush systems.
