WET - wetland treatment
Waterways treatment is critically important to support Natures ecology so its biodiversity is optimised and available as the essential treatment process when needed, particularly around peak rainfall events. Wetlands play a very important role in biological treatment for nutrient removal / absorption that is usually in solution where a wetland mostly provide a healthy water source or as transition into other water cycle processes like infiltration for soil hydration, aquifer recharge and mitigating flood effects.
A wetland is made up of natural processes that often become over grown, overwhelmed and silted up when the design or catchment feeding into a wetland are affected by contaminate sources, erosion or a lack of barriers to restrict physical pollutants like organics, some litter and sediments reaching the water body and settling out in the sludge. The breakdown of these pollutants can that become the source of nutrients like nitrogen and the release of phosphorous carried on this material.
These conditions are responsible for teh likes of oxygen depletion, temperature changes and biological interference as disturbances in the water from competing processes that may also support algal growth further depleting the oxygen demand and other effects.
The surface water and/or drainage flowing into a wetland has to be treated for stormwater water quality improvements with contaminate reductions to prescribed levels for all major contaminate types in the inflows from across a catchment and flow paths in the manner of managing urban flows. The current reliance on an outlet model conducted at the bottom of the catchment for current engineering practice considered as BPM is no more than expedient in using macro infrastructure engineering. It can be seen that the bottom of catchment treatment in large scale GPT devices is questioned as the whole of the catchment contaminate load affects the whole of the water flows to the highest level of contamination in the catchment that only reduces the physical contaminates that are subject to bypass in peak flows negating treatment in many cases. A substantial contaminate load remains and is discharged in convenient waterways that seriously affects the ecology required to perform natures biological processes
The use of waterway discharges are a part of the natural water cycle but the water quality improvements before release are crucial to the environment and the ecology representing natures biodiversity in streams, wetlands, lagoons, lakes, aquifers and ocean outlets.
All to often a wetland in a WSUD framework substitutes for a whole of catchment stormwater treatment device. This practice has proven to be unsustainable and misguided economics. In comparison the SPARKLE | WATER philosophy and product solutions design is around a micro distributed catchment model (MDCM) with networked devices treating surface water flows near where rainwater falls beginning at the top of a catchment and with a treatment train designed for contaminate load step reductions for all major contaminates otherwise affecting and over reliance on Nature's processes. The SPARKLE | WATER treatment train in the MDCM stands ahead of WSUD which supports nature biological processes in the water cycle more effectively and at lower economic costs.
Please consider our approach and the product solutions in support of a logical environmental improved outcome! Wetland treatment for contaminate reduction and removal from the water flows begins before any inflows to a wetland for good WSUD!
