High efficiency separation
The first step in the process is to separate the manure into a thick and a thin fraction. The thick fraction has a high percentage of incoming phosphate and the thin fraction has a low dry matter content.
Reverse osmosis (RO)
After treatment in the ceramic membranes of microfiltration, the permeate enters reverse osmosis (RO). This is a pressure-driven process that uses the semipermeable membrane. High pressure causes water to pass the membrane but salts are held back. It creates clean water and a concentrated liquid; mineral concentrate. Our unique method of filtration ensures a low proportion of concentrate. This means there is little mineral concentrate and it contains a high concentration of minerals. The clean water can be used on your own farm or discharged at a permit.
Microfiltration (MF) with ceramic membranes
Many waste streams consist largely of water in addition to their minerals. Processing the thin fraction ensures that these minerals enter products with an increased concentration. This is done by filtering the vast majority of the water out of the liquid. After separation, the liquid passes through a tumbler filter, which stops the last suspended particles. The filtered out liquid goes to a microfiltration (MF). During this filtration process, undissolved substances larger than 0.1 µm are stopped by the ceramic membrane. This means that anything larger is stopped by the membrane and cannot enter the next step. The driving force for membrane filtration is the pressure differential across the membrane from feed to permeate side. Because of the unique membrane surface, high efficiency can be achieved with a compact installation.
