Wastewater Treatment

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

Parklink’s municipal and industrial wastewater treatment programmes use Advanced Microbial Digestion (AMD), a form of biological augmentation, to improve the efficiency of your existing plant saving money in many areas of treatment plant operations.

Your wastewater treatment plant 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 at least 30%.

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.

Advanced Microbial Digestion (AMD) treatment programs use additives to help regenerate existing biomass in your treatment plant or lagoon.  Based on wide-ranging metabolic pathways and processes including aerobic, facultative, anaerobic and anoxic capabilities, these additives are designed to respond to the unique requirements of the system being treated.  AMD provides the biological tools needed to support environments at all stages with different types of support depending on specific needs.

Parklink utilise Microbe-Lift® Technology which has been used successfully for more than 40 years around the world. Parklink’s bio-augmentation helps to improve wastewater and stormwater treatment plant performance without the need for capital expenditure.

Parklink will visit you on site to gain an understanding of your treatment plant and recommend a course of action that may include preliminary testing and surveys.  We will then design an action plan and treatment program specifically for your situation.

Wastewater Treatment Plant Operations

With ever tightening controls on permits for consent to discharge, it is vital that wastewater plant facility managers and engineers understand there is help available to take their facility to a new level of treatment performance often 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.

Parklink can improve the performance of your wastewater treatment facility using a range of technically advanced Microbial Stimulation Technology processes and systems.

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

Advanced Microbial Digestion

Benefits of Parklink bioaugmentation services include:

  • Increased rate of Carbonaceous BOD conversion.
  • Eliminates and/or manages organic solids accumulation.
  • Improves nitrification and denitrification
  • Quickly re-establishes treatment efficiencies after toxic shock and hydraulic wash out.
  • Improves UV disinfection and faecal counts.
  • Reduces hydrogen sulphide Controls odour production in collection systems.
  • Biodegrades recalcitrant organic compounds.
  • Improves sludge dewatering.
  • Improves solids settling in secondary clarifiers.
  • Improves performance and increases methane production in anaerobic digesters.
  • Controls fat and grease accumulation in collection systems
  • Reduces faecal coliforms

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 comprehensive sediment/sludge sampling in virtually any situation.  Sediment analysis can be done in any pond or lake from anaerobic ponds with floating crusts to facultative wastewater lagoons or fresh water lakes.

Parklink uses mapping software for calculating sludge volumes.  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 Sludge analysis

It is important to understand potential stratification in solids concentrations relative to depth in wastewater sludge when estimating volumes for removal.  This stratification is also a valuable metric to monitor during various stages of AMD.

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 an AMD 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.
