The process begins with effluent passing over FORSI’s specifically designed screen and sediment removal equipment, which removes the larger suspended solids before the liquid is captured into a “blending” tank.

From here the liquid is pumped into the customised container, which houses the filter where a patented infusion process takes place, organic polymers are added to capture nutrients and polishing filtration finishes the process to create the high quality clean water.

“The end result is clean, clear water which can be used for irrigation, re-used for dairy shed washdown or even stock water,” says Darren.

“This water is free from odours, pathogens, total suspended and dissolved solids, and total nitrogen and phosphorous.”

FORSI is working to have the system compliant so water processed by its filtration plant can be discharged direct to the waterways if needed, without the risk of prosecution.

Installing a FORSI dairy effluent filtration system is significantly cheaper than building large effluent holding ponds, says Darren, and treating the water to such a high standard reduces environmental impacts.

The solids and nutrients removed can be composted and used as a fertiliser, says Darren.

“We know of no other filtration system that can take the washdown water directly from the cowshed yard and process for reuse to this high standard.”
