Solid - Liquid Separators TZ-200 and TZ-280​

The solid-liquid separation equipment for cow slurry begins its process by installing a submersible pump with a grinder in the septic tank or in the slurry accumulation pool, which sends it to the separator feed inlet. It is an advanced spiral extrusion mechanical dewatering equipment.

In the machine’s sieve drum, the liquid part passes through the screen filters or sieve until it reaches the overflow hose while the solid part is squeezed and separated through the pressure of the steel auger shaft. stainless steel placed inside the screen. The screw continuously pushes the cow manure forward until it exits through the ejector nozzle, transformed into a fine, smooth and
homogenized manure optimal for cow bedding or organic fertilizer for other animals.

This separator is made up of a feeding inlet, a central extrusion body with an auger, screen filters in mild iron and high-resistance 304 stainless steel, anticorrosive and wear-resistant, with a vibration motor, a reduction motor, a suction, distribution cabinet, electrical panel, discharge device, overflow and outlet pipes, shelf, transport wheels and multi-layer anticorrosive paint. The solid-liquid separation speed is fast and easy to operate; simply pressing the start and stop button for its operation.

In general terms, the water content of fresh cow slurry can reach up to 80% and 90%. The moisture content of the separated manure is between 50 and 60%. This already partially dehydrated manure is suitable for transport.

The resulting liquid is used as a liquid fertilizer to be applied directly to the fields or diluted with irrigation water. It facilitates its pumping and fertigation through irrigation sprinklers or injection into the earth, but with one more advantage, that the same amount of slurry required for its discharge on farmland as required by law for compliance with environmental regulations, requires 20% less unloading area. This 20%, which is the percentage of nitrogen decreased in the separation, reduces the dimension of the accumulation ponds, no crusts are generated that solidify the surface of the ponds, there is less risk of breakage, leaks, savings in maintenance costs and of transport as the transport volume is smaller and the load is easier. And another socially and environmentally important advantage is the undoubted reduction in odor.

The separation allows obtaining up to 30%-35% of dry matter from the separated solid and reduces the total nitrogen by 20%, 50% of the total phosphorus and 20% of the total potassium that the slurry had before separation.
