The Waste Water Treatment Process - opinion

Achieve safe and operational excellence of waste water treatment plants. Global demand for water is projected to exceed supply by 40 per cent in Rising demand, cost and environmental awareness are driving the need for improved efficiency and sustainability of water treatment plants. However, waste water treatment options will be dependent on the type of contaminants present because of the production process and determine necessary treatment to ensure efficient water recovery. Discharge of wastewater requires further treatment to comply with the local environmental regulations. Plant owners and operators face constant pressure to save costs in terms of membrane replacements, consumables, energy and labour. Moreover, feed characteristic changes continuously. Operating waste water treatment plant require continuous optimization of individual process units and chemical dosage. Following SOPs is not enough to maintain the plant performance as operations do not allow inspection of the complex physical-chemical processes inside the individual treatment processes.

All Things Water Course I, Activated Sludge

Every stage in a wastewater treatment process is important to achieve the desired treatment results. However, primary treatment and tertiary are critical to the overall process. In the primary treatment process solids are reduced to a large extent.

Without this step, subesequent treatment would be less effective. In tertiary treatment, harmful microbiological matter is rendered killed or inactive so that it will not cause sickness to those organisim that encounter it. These wastewater treatment methods, are coagulation and disinfection respectively. Each of these processes has multiple ways that they can be accomplished, either by chemical or non-chemical techniques. Each of these wastewater treatment methods has their own benefits and disadvantages.

Course screening and grit chambers will reduce the TSS but must be followed by a more refined solids removal process. Sedimentation and filtration are methods that have been used in the past, but these methods cannot remove many of the smallest particles. This process involves destabilizing the charged particles in the solution. Because of their similar electrical charges, the particles repel one another and prevent them from settling quickly.

Water Treatment Related

To destabilize this electrical charge, an opposite charge must be applied to the solution, enabling the colloids and other minerals to aggregate. There are currently two well-known methods of coagulation:. Chemical Coagulation.

Chemical coagulation is a well known method of particle coagulation. This process warrants the addition of a number of chemical additives to achieve the desired destabilized state. Alum, Ferric chloride, Ferric sulfate, Ferrous sulfate, and Lime are some of the additives used to neutralize the charged particles. Other supplements include polymers, which act as an aid for the aggregation of solids.

The main consideration behind the use of chemical coagulation is that it speeds up the time it would take for the solids to settle on their own. Therefore, decreasing the overall detention time of the wastewater treatment process. Chemical coagulation can also aid the The Waste Water Treatment Process of finer colloidal particles and mineral contaminants. Source particles typically may not settle during a sedimentation process and would pass through a subsequent filtration system. Chemical coagulation is, at its core, an additive process. Though it can reduce the amounts of solids in a solution, it still requires the addition of chemicals to achieve this.

Adding these substances can be quite complex and require extensive jar testing.]
