Wastewater Treatment

Helping to bring your facility or organisation into consent and compliance is our business.

Your wastewater management in New Zealand can remain fully operational during AMD treatment eliminating frustrating and costly plant shut downs and interruptions.

AMD technology also has the ability to reduce or eliminate the need for large capital expenditure, plant expansions or upgrades.  With AMD, the efficiency of your waste water treatment plant can potentially be increased by 30 to 40 percent.

Advanced Microbial Digestion

Bioaugmentation treatment is becoming recognised as the most powerful and cost effective method for removing solids in a safe and environmentally sustainable way.

Parklink recommends AMD for the removal of unwanted solids from both municipal waste and industrial waste ponds.  We utilise microbiological treatments and culturing methods that produce non-pathogenic live cultures indigenous to New Zealand.

We also utilise Microbiological Stimulation Technology, which uses additives in our treatment programmes that help to regenerate existing biomass in your facility.   Safe and totally biodegradable, the material has the ability to create fresh “food” for the existing bacteria in your system to increase the level of microbial feeding and speed up the breakdown of the unwanted material.

Our remediation consultant will visit you on site to fully assess your facility and recommend a course of action that may include preliminary testing and surveys, and will then design an action plan and treatment program for your industrial wastewater management.

Our team will manage the entire process, from the installation of equipment through to completion. A sediment maintenance programme may be required to keep our specialist water treatment in New Zealand running at optimum condition and performing to its maximum.

Sewage Plant efficiency

Now, with tighter controls on permits for consent to discharge, it is vital that sewage plant facility managers and engineers understand there is help available to take their facility to a new level of treatment performance, without having to increase or upgrade the plant infrastructure.

Microbiology, when put into action correctly, is the single most powerful force available that does not require expensive plant expansions or refits to achieve a consistent, positive result.


We can improve the performance of your sewage treatment facility using our range of technically advanced Microbial Stimulation Technology processes and systems. Not only is our bioaugmentation treatments suitable for wastewater collection and treatment facilities but can also be utilised in dairy pond cleaning as well as lake treatment.

Parklink’s qualified microbiologists and industrial chemists will assess your plant requirements and recommend the most efficient and cost-effective way to maximise the biological efficiency of your plant.

Advanced Microbial Digestion

Benefits of Parklink bioaugmentation services include:

  • Increased rate of Carbonaceous BOD conversion.
  • Eliminates and/or manages organic solids accumulation.
  • Improves discharge parameters for consent limits.
  • Quickly re-establishes treatment efficiencies after toxic shock and hydraulic wash out.
  • Improves UV disinfection and faecal counts.
  • Controls odour production in collection systems.
  • Biodegrades recalcitrant organic compounds.
  • Improves sludge dewatering.
  • Improves solids settling in secondary clarifiers.
  • Improves performance of anaerobic digesters.
  • Controls grease accumulation in collection systems

Our range of consultancy services includes sediment patterning, sediment and water analysis, graphing and reporting and treatment efficiency assessments. These services are provided by Parklink in partnership with our experienced microbiologists and qualified industry experts.

Sediment Patterning

Sediment patterning is a useful analysis process for determining quantities of accumulated solids and the chemical and biological composition of the material.

We have the equipment and expertise to carry out sediment sampling in virtually any situation. Our highly accurate sediment analysis can be done at depths down to 20 metres in any pond or lake, including sewerage ponds, waste activated sludge collection ponds, anaerobic ponds and fresh water lakes.

Parklink uses Geo mapping software for calculating sludge volumes in wastewater ponds and anaerobic lagoons. Samples can be collected at any depth without any interference or contamination to the test site and can be independently tested by IANZ accredited laboratories.

Sediment and wastewater treatment analysis

It is important to understand the stages of hydration that sediment goes through when it is being removed using AMD (Advanced Microbiological Digestion) and the relative conversion of organic compounds to water and gas.

Sediment is known to lie in layers of varying states of decay, colour, compaction and biological activity. Parklink has the knowledge and equipment to monitor the progress of the sediment hydration both before and during a removal programme.

We work to strict industry processes and procedures when collecting samples for scientific analysis and where necessary, testing is carried out by approved IANZ accredited laboratories.

Graphing and Reporting

Accurate and meaningful graphing and reporting is essential in understanding sediment and water patterning. At Parklink we use a combination of CAD computer software and Excel based calculating software to calculate volumes of sludge and dry mass.
