85–90% of BOD, TSS, and the tiny amounts of nitrogen, phosphorus, and heavy metals are removed from wastewater during secondary treatment. The third step of wastewater treatment, tertiary treatment, is also referred to as an advanced treatment.
The nitrogen and phosphorus burden in the water is reduced during tertiary treatment. It involves procedures including reverse osmosis, electrodialysis, nitrification, denitrification, ion exchange, activated carbon adsorption, and filtering.
What are the WWT products for tertiary treatment and sludge drying?
· Filtration Method
The particle matter is removed during the filtration process by running water through porous medium. The various media used in the filtration process are typically composed of sand, gravel, and charcoal. Sand filtration comes in two flavours: slow sand filtration and quick sand filtration.
· Membrane-Processes
On the basis of the driving force and separation method, the membrane processes are categorised as Reverse Osmosis (RO), Forward Osmosis (FO), Ultrafiltration (UF), and Nanofiltration (NF).
· Oxidation Systems
In order to eliminate bacteria and breakdown organic pollutants, ozone is added to the process. When oxygen is exposed to a high voltage electric field, ozone gas (O3) is created. Ozone is currently the second most commonly used disinfectant after chlorine.
Technologies/ Products for Sludge drying
The choice of technology depends on the availability of heat sources, the amount of drying, and the kind of material being processed. All drying processes significantly lower operational costs.
Due to the modular structure and straightforward design, maintenance is made simpler. Low temperature operations and the absence of any dangerous gases during the drying process, makes it extremely safe.
The appropriate drying technique for a variety of applications includes:
· Heat pump dryer
It is used for small and medium evaporation capacity.It is a low heat dryer that dries with hot air that is between 70 and 75 °C. The hot air is produced using a heat pump.
· Waste heat dryer
It is used for small and medium evaporation capacity. It is a low heat dryer that operates similarly to a heat pump dryer.
· Paddle dryer
It is used for small to large evaporation capacities. It is a high heat drier that uses steam or thermic fluid, to indirectly heat the product. It can work at temperatures of up to 350 °C.
