Combining Catalytic Advanced Oxidation Processes (C-AOP) and Enhanced coagulation to meet liquid industrial trade waste guidelines

This client manufactures specialty fibre-based and corrugated packaging products and provides support and graphic design services. They have operations in multiple plants located across New Zealand and Australia.

They pride themselves on smart and innovative solutions and were looking for a partner to support them in addressing their wastewater challenges.

The Challenge

Their New Zealand facility produces wastewater containing:

  • adhesive,

  • inks, and

  • starch-based glues.

The wastewater is generated from wash-down of equipment used during the laminating process. The wash-down waste must be treated to consistently meet trade waste disposal compliance requirements.

The customer required a solution which is easily portable to other locations and designed within tight site space restrictions.

Our Solution

Infinite Water’s solution consisted of two processes:

  1. Proprietary Advanced Oxidation Process (AOP)

  2. Proprietary polymer blends

The two processes can be implemented concurrently or separately depending on the wastewater characteristics.

The advanced oxidation process (AOP) solution uses a combination of an oxidiser and a catalyst to break down organic compounds. It usually involves conditioning, flocculation and solid separation (dewatering).

The proprietary polymer blends have been developed for solids separation and are optimised for the site’s wastewater characteristics. These one-shot powder polymers significantly improve separation efficacy and treatment complexity compared to conventional coagulants and flocculants. The powder polymers reduce handling and storage of liquid chemicals on site.

Additional polishing stages may be added to achieve specific treatment objectives or end-use requirement such as:

  • Protection against shock BOD loads

  • Metal removal

  • De-salination

  • Disinfection

  • Nutrient removal

Outcomes

Infinite Water’s solution had the following outcomes for the project:

  • Significant reduction in operating costs as AOP reduces the amount of polymer required

  • Handling of variability in raw water quality – no adjustments required to cope with fluctuations in feedwater quality

  • Reduction in chemical use

  • Significant reduction in sludge volume

  • Reliably meet environmental discharge regulations

  • Improvement in sustainability footprint by re-cycling water for use on site

  • Easy operation

  • Robust process

Services

For this particular customer, we offered a comprehensive suite of services to deliver the project. The range of services that Infinite Water provided included:

  • Water auditing and feasibility analysis

  • Treatment plant optimisation

  • Polymer selection and evaluation

  • Laboratory testing

  • Routine service and maintenance

  • Operator training

  • Installation and commissioning

  • Remote assistance and quality monitoring

At infinite Water we pride ourselves on our in-house facilities and abilities to test and optimise our client’s individual wastewater stream as no industry wastewater is ever the same.

We custom design the treatment solution to always meet our customers objectives, no matter how challenging they may be.

Let us do the hard work for you.
