What are the 5 stages of water treatment?
The 5 major unit processes include chemical coagulation, flocculation, sedimentation, filtration, and disinfection (described below). There are chemicals added to the water as it enters the various treatment processes.
What is wastewater treatment?
For plating and chemical plants the technologies that make up a common wastewater treatment system typically include: An oil/water separator or dissolved air flotation device to remove small amounts of oils. A series of reactors and chemical additions to adjust the pH and precipitate out metals from the solution.
What is a clarifier?
A clarifier to settle suspended solids that are present as a result of treatment . Some sort of filtration to remove all the leftover trace amounts of suspended solids (again, the level of filtration needed will depend on the degree of suspended solids removal required to pass local discharge regulations).
Why do we treat wastewater?
For many years, humans have treated wastewater to protect human and ecological health from waterborne diseases. Since the early 1970s, effluent water quality has been improved at Publicly Owned Treatment Works (POTWs) and other point source discharges through major public and private investments prescribed by the Clean Water Act (CWA).
How does wastewater treatment affect the environment?
Wastewater treatment systems reduce environmental impacts in the receiving water, but create other life cycle impacts, mainly through energy consumption. Greenhouse gas (GHG) emissions are associated with both the energy and chemicals used in wastewater treatment and the degradation of organic materials in the POTW.
How does wastewater treatment reduce energy consumption?
According to the Environmental Protection Agency (EPA), there are several benefits of reducing energy consumption in a wastewater treatment plant. Increased Life of Equipment and Infrastructure – By installing more energy efficient methods, energy consumption can be reduced and therefore extend the life of the equipment.
How to reduce water use?
How to Reduce Wastewater Energy Consumption 1 Conduct an Energy Audit – The first step toward reducing energy use is to do an audit to find out exactly what the energy expenditures are for your plant. 2 Create a Plan – It’s important to create an industrial water treatment plan that is unique to your specific facility. After identifying objectives, it is time to put together an action plan that will need the approval of management and the implementation of training programs. The following are several steps the plan could include: 3 Install New Equipment – Older equipment is more expensive to repair and usually doesn’t operate as efficiently as newer models. It’s essential to have the most energy-efficient equipment possible and to keep up a schedule of preventative maintenance. 4 Improve Pump Optimization – Pumping processes normally use a lot of energy and provide opportunities for savings. It’s important to know which blowers or pumps to use, and how often to use them when conserving energy. 5 Implement Renewable Energy – Employing sources of on-site renewable energy is an excellent way to save on energy consumption while protecting the environment. Solar, water, and wind are potential options. 6 Monitor and Maintain Improvements – You’ll need to evaluate what’s working and what’s not on a regular basis, making improvements where needed.
