Advanced Microbial Digestion
Our unique AMD process has proven to be a cost-effective and non-invasive alternative to dredging in New Zealand for over 12 years. An engineered blend of enzymes and bacteria, AMD breaks down the organic sludge that pond bacteria can’t consume on their own, enhancing overall sludge treatment.
For activated sludge plants, we recommend SELECT-Sludge®, which is a bio-enzyme designed to breakdown undigested BOD. This reduces sludge hauling costs and improves settling, supporting more efficient sludge treatment.
Effective sludge management in wastewater treatment is crucial for maintaining system efficiency, reducing operational costs, and ensuring compliance with environmental regulations. At the heart of a successful approach is a clear understanding of the nature and volume of organic and inorganic matter accumulating in the system. Traditional treatment methods often struggle to provide long-term stability, which is why modern sludge treatment technologies have become essential. These include bio-enzymatic solutions, microbial augmentation, and real-time monitoring systems that improve how sludge is processed, handled, and safely disposed of.
Advanced sludge wastewater treatment approaches not only target volume reduction but also enhance dewatering and improve the quality of remaining biosolids. Reducing sludge volume lowers transportation and disposal costs, making sludge treatment both environmentally sustainable and financially efficient. Microbial additives can break down stubborn compounds such as oils, plant matter, and lignin that conventional systems often fail to process. These innovations have become central to proactive sludge management, allowing facilities to move from reactive processes to a strategic operational advantage. By combining microbial additives with optimized dosing schedules, operators can further enhance sludge treatment, achieving faster breakdown and improved solids conversion.
One of the emerging challenges in sludge management in wastewater treatment is handling highly variable waste streams, particularly from industrial sites. Complex influents demand flexible treatment systems that can adapt quickly to changing conditions. With automation and smart sensors, modern programs can adjust dosing, monitor digestion rates, and predict potential overload scenarios. This adaptive approach protects infrastructure, ensures regulatory compliance, and maintains consistent treatment quality. Strong operational management ensures that personnel follow best practices, while strategic management planning aligns treatment objectives with regulatory standards.
Bio-enzymatic tools like SELECT-Sludge® play a critical role in sludge wastewater treatment, accelerating the breakdown of undigested material, producing less bulk, and improving settleability. More efficient solids conversion benefits the entire treatment system, from improved clarifier performance to reduced polymer usage and fewer maintenance interventions. Integrating nutrient recovery, particularly phosphorus and nitrogen, into sludge treatment processes supports circular economy objectives, turning waste into valuable resources while aligning with sustainability goals. Effective management also involves documenting results, updating protocols, and training staff to ensure long-term program success.
In municipal applications, seasonal variations and fluctuating loading rates can challenge even robust systems. A tailored sludge management in wastewater treatment plan, supported by real-time data and expert oversight, enables operators to make informed decisions, preserve effluent quality, and extend asset life. Comprehensive sludge treatment goes beyond equipment—it involves planning, performance tracking, and continuous improvement. By focusing on efficient sludge reduction, enhanced biological activity, and smart management technologies, facilities can transform sludge wastewater treatment from a recurring operational problem into a long-term strategic advantage.
Furthermore, effective management ensures that sludge treatment programs are sustainable and compliant with environmental standards. Strong management practices involve training staff, optimizing dosing schedules, and monitoring system performance. Proactive management enables operators to anticipate issues, prevent operational disruptions, and enhance the longevity of the treatment infrastructure. By integrating performance metrics, regular audits, and adaptive management, facilities can maintain consistent sludge treatment efficiency, reduce chemical dependency, and support resource recovery. Strategic management empowers teams to make data-driven decisions, ensuring the facility operates at peak performance while meeting regulatory and environmental objectives. With the right combination of biological additives, monitoring tools, and expert guidance, sludge management in wastewater treatment becomes a powerful lever for operational excellence and long-term sustainability.

AMD™ is not a product but rather a holistic system of manufactured inputs, assessments, purpose- built equipment and professional monitoring.
AMD™ is a treatment system used to assist the existing bacterial functionality of wastewater ponds increasing degradation of organic solids. It is based around the application of bacteria, biostimulants and bacterially produced catalysts that promote reactions on organic particulate within the treatment pond.
The AMD™ process has been successfully used to significantly reduce existing organic sediment accumulations in wastewater ponds for over fifteen years in New Zealand. It has also been used to prevent organic particulate accumulations in wastewater ponds on an ongoing and sustainable basis.
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 technologies that have 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. providing proven strategies for improving wastewater and stormwater treatment performance.
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.
Do you spend too much money hauling sludge? Do you have trouble land applying? The catalysts in SELECT-Sludge® reduce sludge hauling and digest the toughest forms of undigested BOD. Things like lint, paper fibers, plant tissue, and oils typically settle out in a wastewater plant, then end up as digester sludge.
SELECT-Sludge® contains a biochemical catalyst, developed by our lab, that when added into a wastewater treatment plant, digester or sludge storage tank it degrades all the grease, oils, waxes and papers the bacteria cannot. This liberates difficult-to-access carbon and turns it into food for the bacteria, creating less sludge.
This improves settling, creates a denser sludge and gives you much less to haul. It’s far cheaper than diesel.
SELECT-Sludge® reduces both polymer cost and sludge hauling, while increasing the percent cake solids.
The catalysts in SELECT-Sludge® convert insoluble BOD to soluble simple sugars and materials so the bacteria can digest it. This process promotes great digester sludge reduction. Many new wastewater treatment plants do not have primary treatment. This means the aeration basin catches everything including hard-to-digest fats, surfactants, paper products, and complex chemistries sent by industries.
In other words, all the insoluble BOD goes into the digester or sludge storage tank, and SELECT-Sludge® is going to significantly reduce it.
