About Houle

Houle effluent equipment is designed to process effluent and utilise if more efficiently.

Dairy farm effluent is a valuable resource. We use it to maximise pasture growth, reduce fertiliser costs and increase milk profit.

With a Houle effluent management system, you can manage effluent storage better, make valuable nutrients go further, be more flexible with grazing, and lower stress levels during the busy periods.

You can also significantly reduce fresh water usage and associated costs with the ability to recycle water for wash down.

Separation

Separating effluent into solid and liquid components makes managing your effluent easier; more efficient storage, less maintenance, greater flexibility for application and the ability to recycle water.

Houle has developed the ultimate range of separators than can be used stand alone or in configurations with other separators, to suit any farming system.

Slope screen separator uses a sloped stainless steel screen to remove solids from a lower consistency effluent stream

XPress Roller Press squeezes liquid from higher consistency solids between a perforated stainless steel roller and rubber roller, for higher dry matter output

Slope Screen SeparatorRemoves solids from an effluent stream

“Due to the design and the total lack of moving parts the minimal R&M that is required gives me the time and money to spend elsewhere in my business”.

Simon Belton - Te Poi


How it operates

• TheHouleSlopeScreenSeparatorisinstalledonaplatformaboveaconcrete solids bunker

• Theeffluententerstherearoftheseparator(viaapurposebuiltmanualflow regulator) so an even and suitable flow of effluent is distributed across the top of the screen panel

• Astheeffluentfallsdownthescreen,liquiddrainsthroughthewirescreen,while solids slide down the face of the screen into the bunker below

“We are system 5 high input milking 1600 cows - the solids coming off the rollers are exactly the consistency we were looking for - about 24% DM. This allows us to cart it down a public road and spread it straight away”.

Piston PumpsFor transfer of thick manure from barn to storage or separator

“Heavy effluent from a barn situation can be easily managed with the Houle range of hydraulic piston pumps - the Magnum, Futuro and Electromix System can handle straw, sand or sawdust with reliable flow rates and low energy costs”.

Matt Rice - GEA FT


Magnum Pump Futuro Pump

Transfers thick effluent with high straw content directly from barn to main storage.

Transfers thick effluent from barn to long-term storage area at a faster rate than the Magnum.

Agitates, chops and evacuates effluent so it can be easily transferred through PVC pipes over long distances from reception pit to storage.
