Slurry storage specialists Agri Environmental Group (AEG) recently contacted T-T in search of a complete slurry management system for a customer with a sensitive surrounding environment.
T-T provided all of the components needed for an efficient and environmentally responsible slurry management system, using Cri-Man manufactured products for their reliable and industry-trusted design.
Screw Screens Improve Water Treatment Infrastructure
During a programme of continual improvements to water treatment infrastructure, two of T-T’s distributors contacted us regarding separate schemes that required the replacement of existing screw conveyors that were beyond economical repair.
We sized and selected two SFC Screen Compactors, suitable for channel or tank installation for screening of municipal and industrial wastewater.
Turning Farm Slurry into a Hygienic Bedding Alternative
A farm in Sussex wanted a cattle bedding alternative that would reduce the amount of slurry held in on-site storage. This would not only free up space on the farm but also reduce the risk of any environmental damage occurring from leaks or the production of harmful ammonia gases.
We supplied a HBC Biocell from Cri-Man, a solution that turns slurry into a hygienic bedding alternative for cattle complete with chopper pumps, separators, hoses, level control, control panel and more.
The T-T Agricultural and Environmental team were approached for help with a slurry mixer that was prematurely corroding, installed in digestate of an unknown pH value. The mixer was constructed of insufficient materials, leading to expedited wear of the equipment and vastly reducing the quality of the digestion process.
Our agricultural experts recommended a TBM Range mixer from Cri-Man, constructed from cast iron and stainless steel, with a Nitec anti-corrosion coating.
A client came to us experiencing issues with their current dirty water management processes, reporting consistent pump failures that were costing both time and money to repair.
Our agricultural team assessed the client’s issues and the needs of the site, using their expertise to specify three automated pump systems for the farm that would be high quality and low maintenance.
How do I size a water boosting set for irrigation?
This depends on the size of your application, the geography of the area and factors such as head losses and ancillary equipment. A site with high water demands, a hilly landscape and several water outlets will need a booster set with more pumps to match the application's demands and operating parameters.
For expert advice on choosing the ideal water booster set for your irrigation application, contact our team via telephone on +44 (0)1630 647200, email at response@ttpumps.com or via our enquiry form.
An irrigation pump is a water boosting pump that provides pressurised water to an area requiring irrigation, e.g. to sprinklers in a garden or channels in a field.
Where to install an irrigation pump?
Where an irrigation pump is installed will depend on the availability of water and a power supply as well as the application's terrain, as this can effect pressure requirements.
Control panels, Variable Speed Drives and monitoring systems can all be supplied to assist in water booster pump management. The T-T Controls department has a range of standard control solutions suitable for irrigation purposes, as well as the skills and facilities to create bespoke control panels that match your specifications.
The type of Layflat hose you need is determined by the medium that it will carry and the terrain it will be traveling/working on. These factors will dictate the most optimal materials and construction grades for your application.
For help in choosing the most suitable hose for your application, call our experts on +44 (0)1630 647200, email response@ttpumps.com or complete and enquiry form online.
How long does a layflat hose last?
The lifespan of any layflat hose is dependant on how it is used and cared for, there is no standard duration.
What lengths do layflat hoses come in?
The industry standard is 200 meters per hose, but this is not the limit. Hoses can be produced in lengths up to 600 meters, allowing for less couplings needed on the reeler.
Can I drag a rubber hose?
Rubber hoses are designed to be used as a static hose, which T-T would always recommend.
Are there different grades of TPU available?
Yes, TPU is available in various grades with many brands opting for a lower grade to cut costs. We use a high grade for all our TPU hoses, offering the best wear resistance possible.
What sizes of hose do you stock?
Here at T-T we hold large quantities of 102mm and 127mm in both rubber and TPU, with 114mm and 150mm available upon request.
What is the difference between slurry, layflat and drag hoses?
Slurry Hoses - Designed for handling abrasive slurry materials, commonly used in agricultural applications.
Layflat Hoses - Flexible hoses that can be flattened for storage and transportation, ideal for transferring water or fluids over long distances.
Drag Hoses - Heavy-duty hoses for dragging liquid manure or fluids across rough terrains in agricultural operations.
SEPARATORS & SCREENING FAQS
What are the benefits of separating slurry?
Slurry separating provides several benefits to farms and agricultural processes:
Increased storage - separating slurry into solid and liquid contents allows for more compact storage, meaning less space and facilities are needed on site.
Organic farming - separated solids and liquids from slurry can be utilised for a range of other applications, such as an organic fertiliser.
Environmental safety - separating and storing slurry solids and liquids separately vastly reduces the risk of volatisation occurring, which can lead to leaks of harmful gases and damage to the surrounding environment.
Green bedding - High dry matter-separated solids can be used as a source of green bedding for cattle.
A slurry separator works by pressing/squeezing the raw slurry to remove the liquid fraction. T-T's screw press separators use a double-threaded Archimedean screw and wedge wire screen for this process.
What screen sizes can be supplied with my separator?
Separators can be suppled with screen sizes of 0.25mm, 0.50mm, 0.75mm and 1mm. Smaller mesh sizes allow for finer solids particles to be separated from slurry, whereas larger sizes will separate larger solids.
Is the HBC Biocell a complete separation system?
No - The HBC Biocell forms part of a complete system, it is designed to pasteurise the solid fraction that is discharged from a separator.
What is green bedding?
RMS (Recycled Manure Solids) can be used as a green bedding option for cattle if it conforms to DEFRA Regulations, one of which is that the slurry separator unit being used needs to produce solids of at least 34% dry matter (DM).
A standard slurry separator will achieve a max dry matter of approximately 25-30%, whereas a high dry matter version can achieve up to 30% DM plus - T-T's Dewatering Separator Range can achieve up to 38% DM solids.
Our HBC Biocell adds an additional pasteurisation step to the process that guarantees hygienic and sanitised bedding to protect your cattle from diseases.
What is volatisation?
Volatisation is the process of nitrogen decomposition within unseparated slurry whereby ammonia is released and converted into a gas or vapour. This can occur during slurry spreading (fertilisation) or storage, and if released can have negative effects on air quality and the surrounding environment.
Yes, T-T treats each application individually, providing a separator tailored to suit the needs of your site with one of four scren sizes we have available.
What dry matter do slurry separators achieve?
A standard slurry separator will achieve a maximum dry matter of approximately 25-30%, whereas a high dry matter version (green bedding version) can achieve up to 36% dm.
AGRICULTURAL MIXERS FAQS
How do I choose a mixer?
T-T Agricultural & Environmental offers several mixers, designed for use in a range of applications:
TBM Mixer Range - Offers excellent mixing efficiencies on heavily soiled and highly viscous applications where additional torque is required, such as food and beverage processing or chemical manufacturing.
TBX Mixer Range - Fully constructed from 316 stainless steel, making it ideal for food processing or highly corrosive applications, directly driven by the motor for suitability with low viscosity liquids.
MXL Lateral Mixer Series - Perfect for above ground slurry stores where the diameter exceeds 30 meters and usually used in conjunction with the TBM Range to allow even homogenisation in larger above ground slurry stores.
MXT Mixer Range - Tractor driven mixing solutions for below ground slurry stores where no electricity is available, offering a versatile option for farmers.
For further advice on choosing the ideal mixer for your application, contact the experts at T-T by calling +44 (0)1630 647200; emailing response@ttpumps.com; or by completing our online enquiry form.
What is the maximum total solids a mixer will handle?
The Criman TBM, MXL and MXT are capable of haneling upto 12% total solids, with the TBX and AF range limited to 8% total solids.
Can mixers be installed in any shape tank?
Mixers work best with circular tanks, however all tanks have the risk of developing dead spots. This is why T-T's mixers are supplied with rotatable guide-rail systems that ensure consistent and efficient mixing.
What is a dead spot?
A dead spot reffers to an area of the tank that is least effected by the action of the mixer, causing a build up of material in that spot.
How do I choose the best size mixer for my slurry storage tank?
T-T's mixer range starts at 0.75kW and finishes at 25kW, for expert advice on choosing the right size mixer for your application, contact the team on +44 (0)1630 647200, response@ttpumps.com or via our online enquiry form.

ANAEROBIC DIGESTION FAQS
What is anaerobic digestion?
Anaerobic digestion is a biological process for decomposing various materials that is primarily used for the production of biogas. Anaerobic digestion involves the breakdown (decomposition) of organic waste materials such as sewage and slurry.
What is the difference between a chopper pump and a macerator pump?
While both chopper and macerater pumps will break down fibrous materials, a chopper pump is a heavier-duty option designed for particularly difficult applications such as handling raw slurry. Macerator pumps are aimed at handling softer solids, such as general wastewater.
What is a piston pump?
Piston pumps are a kind of positive displacement pump where a piston moves the fluid. They are designed with liquids containing heavy solids in mind, with Cri-man'sPLD system being capable of handling up to 18% total solids.

UMBILICAL & SLURRY PUMPS FAQS
What is an umbilical pump?
A high pressure pump that is used for spreading/transporting stored fluids, generally featuring a heavy-duty chopping system that cuts solids and other fibrous materials before pumping to prevent any blockages in the system.
What do umbilical pumps do?
Umbilical pumps are used across many industries for transporting fluids such as oil, wastewater or food products:
• Transporting slurry from storage to fields for fertilising purposes. • Transfer of liquid from lagoon to lagoon.
T-T’s umbilical pumps are designed for heavy-duty liquid pumping, with the inclusion of choppers to break down large solids.
How does a slurry pump work?
Slurry pumps use a combination of more free passage within the pump case and a higher torque motor to pump heavier liquids.
How far can you pump slurry?
The distance you can pump slurry is very much dependent on the pump used and the viscosity of the liquid, small pumps are capable of transferring a few hundred meters whilst some large units can cover over a thousand meters.
How do you pump slurry?
For slurry to be pumped, the liquid needs to be conditioned. This can include additional water or a mixer to generate a pumpable liquid.
How do you put a slurry pump on a tractor?
To mount a slurry pump on a tractor, you will require a frame that can be attached to the three-point linkage at the rear. Once attached, the pump can be driven by a PTO shaft.
