The Separation Process

 

Distributors

The WSP Press Separator range is a tried and proven method of separating solids from farm dairy effluent.


By removing the solid particles from your effluent with a WSP Press Separator you to have the ability to fully utilise your farm dairy effluent as a fertiliser resource.
An equally important benefit of a correctly installed Press Separator is to keep unwanted solids out of your storage pond.

 
WSP Press SeparatorMade entirely from stainless steel, the WSP2501, WSP4001 and WSP7001 Press Separators are practical cost effective and environmentally friendly solution for New Zealand dairy farms.

They are built to provide years of consistent effluent separation.
By having six models, we can ensure a good match to your specific farming requirements.  Outdoor herds or indoor barn systems, we have a solution.

New Zealand's outdoor farming practices provide unique challenges for effluent products.  In many circumstances imported screw presses do not handle farm dairy effluent well.

Whether the liquid is directly off the cow shed or from a feed pad the WSP press separators can be incorporated into the system.

Water Supply Products will work with our authorised resellers to design a effluent system to meet your farm requirements.



The WSP Press Separator is designed and manufactured in New Zealand by people with practical experience with dairy effluent in New Zealand conditions.

All parts are “off-the shelf” products, readily available in New Zealand.

The effluent separator process starts with the wash down water passing through a stone trap, the liquid is then collected in a sump or collection tank, then then pumped through the WSP press separator.

With our standard screen opening size of 0.5mm (other sizes are available) the filtered effluent water can be passed through small diameter sprinkler nozzles, such as irripod sprinklers, allowing for low application rates.


This stops the blocking of the soil structure and reducing the chance of leaching the effluent into the groundwater/rivers.  The effluent can then be readily taken up by the plant and provides a usable fertiliser for the plant.


Studies have shown the application of dairy effluent at high rates can result in sealing of the soil surface and loss of effective macroporosity for a number of days. This is due to the solids in the effluent clogging the soil pores. (finding from green dairy, alternative dairy effluent application methods)
