Every industrial wastewater has different characteristics – contaminant profile, volumes, operational variability, site constraints and disposal requirements.
The most cost effective treatment solutions are those that are developed specifically for a particular industry’s situation rather than forcing an off the shelf treatment process to fit the wastewater framework.
The Water and Carbon Group has a unique advantage for Industrial Wastewater Treatment solutions. Our team comprises both process engineers with ecological engineering specialists, which gives us a diverse range of process tools that we can draw upon to ensure that we develop the most cost effective solution for our clients.
The Water and Carbon Group is a unique contractor that specialises in the design, building and operation of low energy wastewater treatment and ecological infrastructure solutions.
Our general approach to developing these solutions involves the following steps:
- Determine options for final disposal: It may seem back to front, but quantifying the expected performance requirements are essential to ensuring that treatment plants are not overdesigned. Why treat to class A+ water quality if only class C is required. Understanding the full water balance and disposal options enables development of treatment processes that are appropriate to the end outcome.
- First consider lower energy solutions: There are many different treatment technologies that can achieve the same final effluent quality – each has strengths and weaknesses. Generally, the lower energy technologies (Waste Stabilisation Ponds/wetlands) require larger footprints than higher energy processes (e.g. MBR’s). Therefore, if sufficient area is available, technologies such as waste stabilisation ponds (WSP), gravel media filters, and constructed wetlands that minimise mechanical requirements (pumps, aerators, membranes) and are simple to operate should take precedence.
- Next consider alternatives: If available land area is constrained, or the economics of larger footprint passive solutions are prohibitive, then consider whether lower energy engineered solutions can be utilised in the process train e.g. high performance plastic media trickling filters as replacements for mechanically aerated bioreactors. Hybrid solutions can also be developed, e.g. chemical dosing, trickling filter, wetland, Ultrafiltration for A+ reuse.
- If no other solution fits the match: THEN consider the more expensive process technologies to meet your needs e.g. MBR.
The Water and Carbon Group have the necessary process expertise to consider such diverse range of process options that won’t be presented by mainstream process equipment suppliers. Our approach is to mix technologies if required to ensure that our clients end up with lowest whole of life costs solution that will meet their project objectives.
