Whether your meat processing plant is in an urban or regional area, and you discharge wastewater to trade waste or the environment, irrigate or intend to reuse the treated wastewater, Hydroflux will always design and construct a wastewater treatment plant to suit your specific needs.
Hydroflux has experience and a range of products and designs suited for wastewater treatment from meat processing facilities including; DAF systems, anaerobic and aerobic plant, and associated sludge handling equipment. We also provide process water and advanced water treatment solutions and undertake complete design and construct contracts.

Wastewater Treatment Process
For urban facilities where wastewater is discharged to sewer as trade waste, Hydroflux would typically supply one of number of types of automated rotary screens followed by a HyDAF system which will generally enable compliance with trade waste discharge requirements.
Hydroflux will always design the system with an appropriate chemical program to suit the desired degree of treatment. Chemical programs can involve one or a combination of pH control, coagulation and flocculation.
The following diagram shows a typical wastewater treatment process for urban sites that Hydroflux would implement when wastewater is being discharged to the local sewage treatment plant.
Hydroflux will always consider each project on its own merits taking into account performance requirements, CAPEX and OPEX. We use process equipment and designs mostly sourced from our own proprietary range and will undertake turnkey design and construct contracts.
Dissolved air flotation
The capacity of the balancing facilities, the size and configuration of the DAF, and the chemical program applied to the wastewater will always depend on type of processing facility and the discharge water quality required, which varies considerably around the regions.
Hydroflux has a comprehensive range of dissolved air flotation models ranging in capacity from 10 kL/hr to 1000 kL/hr to suit any meat processing application. The HyDAF dissolved air flotation units are configured with several options to accommodate automated removal of settled sludge and cleaning.
Hydroflux will calculate the volume of sludge that is generated based on wastewater flow, solids load, and chemical program employed, and will evaluate sludge handling as a separate project on its own merit. In cases where sludge dewatering is viable, Hydroflux will select the most appropriate dewatering system from its extensive range of dewatering products.
There are many factors that are used to determine the viability of onsite sludge dewatering including:
- Dewatering equipment used
- Achievable dry solids concentration and volumes
- Costs and disposal routes of slurries and dewatered cake
- Liquid and solids handling methods
- Wastewater flow
- Incoming solids load
- Level of treatment applied
- Chemical programs used
In some instances where sewer discharge requirements are outside the limitations of flotation technology, Hydroflux will design and construct a biological polishing stage down stream of the DAF. Biological treatment is typically used to further reduce the organics (BOD and COD) and nutrients (Nitrogen and Phosphorous) which can be a requirement for discharge, economically viable based on trade waste costs, or as a precursor to enable recycling wastewater back to the processing plant.
Often MBBR processes are effective due to their compact nature, although alternative aerobic or anaerobic treatment processes can be suitable depending on the water quality required.
Regional facilities offer more opportunities to incorporate sustainable anaerobic treatment processes that generate energy from wastewater.
Hydroflux will design the most suitable process from a comprehensive portfolio of primary treatment equipment followed by pond or tank based aerobic or anaerobic treatment plants configured to meet the tightest nutrient discharge limits or to enable potable or non-potable reuse.
The following diagram shows a typical wastewater treatment process for regional sites that Hydroflux has the skills and experience to design and construct.
Hydroflux has a wealth of experience in the design and construction of wastewater treatment systems and Advanced Water Treatment Plants that convert wastewater into potable water for the meat industry. We have worked with many state and federal regulators such as Food Safe Australia and The EPA, and fully understand the regulations pertaining to the discharge or reuse of non potable and potable water.
Anaerobic treatment in the form of Covered Anaerobic Ponds (CALs) are an ideal solution to reduce the concentration of organic material in the wastewater whilst allowing the opportunity to generate biogas. CALs are best suited to large flow and organic loads such as those found at rendering facilities.
Hydroflux design and construct a range of anaerobic ponds and the associated biogas handling equipment to supplement the natural gas supply to boilers or for creating electricity via Cogen plants.
To achieve a water quality that is suitable for irrigation or discharge to the environment, or if wastewater is to be reused, aerobic treatment is required. Hydroflux has a comprehensive range of aerobic treatment processes designed for the efficient removal of organics and nutrients. These designs include: SBRs, MBBRs, MBRs, or activated sludge plants, all of which can be configured in above ground tanks or in lagoons.
Hydroflux has access to one the most efficient fine bubble diffuser systems in the Aerostrip which reduces the power consumption for aerobic treatment by over 50% compared to conventional methods. Aerostrip fine bubble diffusers can be incorporated into tanks or lagoons.
Handling of waste activated sludge is an integral component of an aerobic wastewater treatment plant. Hydroflux has vast experience in the dewatering of primary and secondary sludges using centrifuges, belt presses and screw presses.
The popularity of screw press has increased exponentially with recent advances in screw press design and are now favoured by municipalities and industry alike. One of the main benefits of the screw press is its ability to handle large volumes of dilute WAS (2000 – 3000 mg/L) directly from an aeration tank without the need for a pre-thickening stage.
Process water treatment
The Australian red meat industry is a global leader in the supply of sustainable produce. Through continuous innovation, the red meat industry is seeing significant reduction in water usage as well as energy consumption and greenhouse gas emissions. The industry has significantly reduced its water footprint, driving efficiencies to reduce water consumption. The red meat industry is also well placed to implement further savings through the utilisation of advanced water to reduce reliance on local freshwater supplies. Efficient water solutions are critical for the red meat industry’s goal to ensure long term sustainable growth, particularly in regional and remote areas where many processors are located. Hydroflux, as a leader in this field is well placed to support the continued sustainable growth of the red meat industry.
Hydroflux have a range of proven, highly efficient process and advanced water solutions for the red meat industry, including:
- Bore water treatment systems
- Surface water treatment systems
- Media Filtration & Activated carbon filtration
- UV sterilisation
- Reverse Osmosis
- Softening/Ion Exchange
Advanced Water treatment
Advanced Water Treatment is the treatment of wastewater for direct potable use. Hydroflux engineers pioneered Advanced Water Treatment in the meat industry in the early 2000’s. Hydroflux continues to be at the forefront of Advanced Water Treatment and recycling technology and are investing in research into the treatment and recovery of salts so that in the future, and in particular, rural facilities and their communities will reap the benefits of Advanced Water Treatment.
Although an AWTP utilises a series of conventional wastewater and water treatment technologies such as Ultra Filtration , Reverse Osmosis and disinfection that can be applied down stream of a n aerobic biological plant, the main features of an AWTP are the implementation of 1), a multibarrier approach and 2), establishing a suitable and acceptable risk management plan.
The diagram below shows the relationship of framework elements for a recycled water management system that Hydroflux can provide including the design, construction and operation of the AWTP.
The processes required to embark on an AWTP project are not insignificant so working with a company that has a proven track record is essential. As well as having the experience and skills to design and construct an Advanced Water Treatment Plant, Hydroflux will also work with you to develop the risk management plan and obtain approvals from all stake holders prior to construction.
