Effluent Solutions

Do you spend a lot of valuable time working on herd effluent? 

Put your herd's effluent to work for you!

Effluent disposal is an important part of your farming operation, however, it doesn't need to be a task that costs you valuable time and planning.  Effluent disposal systems can range from treatment ponds to land-based treatment systems, where the effluent is pumped from sumps or holding ponds.

Pumping from a large storage facility is generally preferred by regional councils, but no matter the situation, there is a need to minimise your concerns about effluent disposal. It's a big issue that you need to get right, so speak to the experts.

Apply your dairy effluent back onto your farm soil and never over-spend on fertilisers again.

Investing in a well-designed effluent system can give you a significant financial return on investment by reducing fertiliser expenditure, minimising animal health issues, and significantly cutting down labour inputs required to manage effluent disposal.

Effluent Pumps

The majority of effluent pumps are designed to pump solids up to 10% and normally have an open impellor.

 

They come in different sizes depending on the required volume and head.

 

They start at 5 to 35 horsepower or as high a head as required.

 

The open impellor pump is primarily used to run such applicators as the Larall Smart Hydrant, Rain guns, Spitfire Irrigator and Traveling irrigators or pretty much anything with a larger nozzle that say 10mm.

The open impellor pumps are also used as transfer pumps for effluent containing solids. This includes feeding mechanical separators, transferring from sump to ponds and vise versa. Transfer pumps are usually high volume, low pressure.

With the introduction of Low Application Rate systems where solids have to be removed such as Irri-Pod, K-Line and Larall, the closed impellor pressure pump can be used.

 

These pumps are usually used to pump water. The closed impellor pump will produce a greater volume per hour that the equivalent size closed impellor making them more efficient.

There are four different types of effluent pumps.
1. Long Shaft (open impellor)
2. Short Shaft (open impellor)
3. Submersible (open impellor)
4. Shore Mounted (open impellor and closed impellor)

The main open impellor effluent pump brands are Doda, Gillies, Numedic and Reid & Harrison. There are many closed impellor pumps. Some brands are Davies, Gillies, Grunfos and Lowara.

Effluent Storage

Effluent storage is a critical part of the process allowing ‘deferred irrigation’ and typically the biggest infrastructure investment when considering a new effluent system. Therefore it is firstly important to get the capacity of the storage facility right and ensuring you have an accredited Storage Calculation which will stand the test of time.

 

The right storage calculation will consider a range of key inputs ranging from your soil type, climate, existing irrigation capability, and where the system could be developed in the future. You may need to consider extra storage for added flexibility or management objectives.

It is also important to consider the various options available such as ponds, tanks, and bladders, as these can lend themselves to the site in different ways. One option is often more practical and/or cost-effective than the other for a given site. The team at Effluent and Irrigation can drill down the capacity and best options for your farm – do it once and do it right!

EFFLUENT STORAGE OPTIONS

 
Effluent Stirrer & Aeration

Whether simply transferring effluent or irrigating, it is always recommended to agitate effluent while pumping. When pumping to the irrigator it means an even mix (nutrient content) of the effluent. It also makes for more efficient pumping and minimises any blockages along the way.

 

Stirring the storage facility will also minimise any solids build-up that can create problems eventually and often involves a costly desludging exercise. This can range from floor mounted stirrers, pontoon stirrers and also Aeration systems.

 

SOLUTION OPTIONS: Submersible Stirrers, Pond Floor Stirrers, Pontoon Stirrers, PTO Stirrers, Aeration Systems

 
Effluent Solid Separation

Removing solids from the effluent is an option to allow more effective downstream effluent management and is a requirement for some farms. There are a variety of benefits and considerations when deciding on solid separation and this will be different for every effluent system. Generally those farms that have a higher input of feed and / or off pasture facilities (i.e. feed pads) present  a greater need for solid separation. The common solid separation systems on farm are what we call ‘primary’ solid separation. These systems are designed to remove the majority of particles over 1mm in size. Solid particles less than 1mm in size, typically referred to as fine suspended solids, require secondary solid separation to remove them. These finer solids would normally only be removed for a higher green water quality or nutrient removal process.

 

Some of the benefits of solid separation include:

 

  • Minimising blockages in pipes & irrigation equipment

  • Green water recycling (washdown)

  • Easier storage management – solids settling & crusting

  • Enhancing storage capability

  • Managing feed pad effluent

  • Low application rate irrigation

  • Reduce blinding of pasture/soil

  • More efficient pumping

  • Nutrient load management

 

SOLUTION OPTIONS:  – Mechanical Solid Separators, Passive Screen Solid Separators, Drying Beds, Weeping Walls, Pond Systems, Sediment Traps

 
Flood Wash

Flood Wash is a popular method to clean yard areas and feed pads. It saves time and being a low pressure / high volume system this also allows the use of green water recycling, making for an efficient practice. We specialise in a range of Flood Wash systems ranging from automated Flush Valves through to simple retrofits that can be used without cutting into concrete.

IT'S WHAT WE DO

What our clients have to say. 

“We needed an effluent system that required little maintenance and that would definitely comply with local council regulations.

 

In the past we spent around 14 hours a week just on effluent disposal, now it is only about 1 hour a week.

 

That is HUGE saving in man Power for us.”
