Industrial wastewater treatment is a kind of environmental remediation process that treats contaminated water from industrial sources for consumption, manufacturing or disposal into the sewage system. Each system varies depending on the needs of the facility but most of the technologies that make up the systems are the same. Here are some of the most in-demand industrial water treatment systems:
- Raw Water Treatment System
- Boiler Feed Water Treatment System
- Cooling Tower Water Treatment System
- Wastewater Treatment System
Raw Water Treatment Systems
When we say raw water, we are referring to any untreated water that is seen in the natural environment. These can be rainwater, groundwater, lakes, rivers and wells. For industrial setups, raw water may be used for cooling, rinsing, product formulations, or even for human usage if correctly purified. Raw water treatment systems are used for pretreatment and optimization of the water source. The focus is on the improvement of production efficiency and process performance for a certain application. For instance, pretreating cooling tower/boiler feed water, process/production water and lastly water for drinking purposes. More often, raw water treatment concentrates on providing protection for downstream equipment from the effects of scaling, fouling, corrosion as well as other forms of wear and tear due to the presence of toxic contaminants in the water source. The process calls for the removal of suspended/colloidal silica, iron, water hardness and bacterial contamination.
Boiler Feed Water Treatment Systems
This process involves removal of harmful impurities before admittance to the boiler and also for the control of acidity and conductivity of the water. A typical boiler feed water treatment setup is composed of a primary treatment and probably polishing depending on the amount of boiler pressure, steam and chemistry of the boiler feed including makeup of water.
Cooling Tower Water Treatment Systems
This system is used for the protection of cooling tower components from damage caused by contaminants that are present in the feed water, circulation water and lastly blow down water. Some of the contaminants that the process removes are: silica, sulfates, TDS, TSS, biological materials, chlorides, iron and hardness. If left untreated, the cooling tower feed water can cause severe scaling, growth of bacteria, foul odor resulting in costly plant downtime, lessened productivity and high maintenance and equipment replacement expenses over time. It works by removing harmful impurities based on manufacturer recommendations for water quality requirements for the kind of cooling tower used.
Industrial Wastewater Systems
This kind of system may be used to convert spent streams into an effluent that can be reused or discharged safely to the municipal treatment facility or the environment. An effective wastewater treatment system can prevent undue harm not only to the environment but also prevent diseases. The complexity of a wastewater treatment system will depend on compliance regulations and also the composition of your waste stream. The first step in the process is called clarification where metals, silica and other suspended solids are removed. This is followed by disinfection to remove harmful bacteria, fungi and viruses. It is then followed by water softening to remove hardness. Sometimes special processes are used to specifically remove certain metals and organics contaminating the water. Finally, distribution for reuse or discharge to a local sewer or to the environment.
