Steps And Process Of Industrial Water Treatment

Industries use vast volumes of water for manufacturing processes. Water released from manufacturing facilities contaminates nearby water bodies, and hence Water Treatment before discharge is essential. Companies must take necessary steps for determining the after-effects of toxic industrial waste and follow stringent environmental laws. Environmental laws critically define the treatment procedures necessary for protecting surrounding water bodies and the underground water table. Wastewater treatment plants help convert the liquid waste into relatively less toxic fluids.

It also involves the removal of the solid waste present in wastewater. Effluent treatment primarily comprises of two stages that involve the removal of dissolved and suspended contaminants. Industrial water treatment facilities are necessary for the removal of specific pollutants like heavy metals and phosphorus. Adopting a proper Water Treatment technique ensures that the surrounding area users have access to sufficient potable water. Industries must employ proven methodologies and tools depending on the contents of the effluents

Wastewater Treatment Steps

As discussed above, Water Treatment contains different types of contaminants, and hence the process involved for the treatment is also different. The necessary water treatment steps for industrial and municipal wastewater pretty much similar.

Step: 1

Screening for the removal of large items and grit

Step: 2

Primary clarification for separation of organic solid waste

Step: 3

Aeration promotes the conversion of NH3 to NO3. It also provides the necessary oxygen to encourage the growth of bacteria.

Step: 4

Clarification for removal of sediment usually done through chemical treatment

Step: 5

Infection with the use of UV chlorination and other techniques

Step: 6

Discharge of water, disposal of solid waste, and reclamation of biogas and biomass are solid.

Step 1: Wastewater Screening

The primary purpose of Water Treatment is to remove solid waste from wastewater that can cause damage related to process equipment. The presence of large particles also reduces the efficiency of the system and result in contamination of waterways.

Water Treatment Dubai follows various screening methods that include a climber screen for segregating submerged solid waste from the water.

Step 2: Primary Clarification And Separation

Clarification helps in removing suspended solids from the effluent. The result is a clarified liquid for downstream treatment procedures.

Two types of Water Treatment clarification procedures are:

Primary Clarification

Remove solids from wastewater before biological treatment.

Secondary Clarification 

Quickly return activated sludge into the aeration tank for biological treatment.

Industrial wastewater contains large volumes of the suspended waist. Solid waste contains pulp fibers from plants, Metal particulates, steel, iron plants, coke from power plants, oil, and grease from the food processing industry, and play particulates from run-off. Industrial wastewater treatment plants always include solid waste removal in the primary treatment stage. Solid waste separation in later stages of Water Treatment helps the removal of biological solids. The filtration process removes suspended residual compounds at the final stages of the treatment.

Aeration

Aeration is a vital step in the activated sludge removal process. Different types of aeration methods in Water Treatment include:

High Rate Aeration- This process is useful in the log growth phase. In this stage of filtration, excess food is present through recirculation in the biomass population. Here the effluent consists of acceptable levels of biochemical oxygen or BOD.

Conventional Aeration- It is the most popular activated sludge removal process, followed by industries and inequalities. It is the left capital-intensive process compared to extended aeration.

Extended Aeration

Commands with extended aeration facility require a longer oxidation period to reduce effluent BOD levels. The capital and operating costs of this process are relatively high.

Secondary Clarification

Fine particles present on the surface of water little each other as the body has a negative charge. Methods like flocculation and coagulation are necessary for this stage of Water Treatment.

Water Treatment  Coagulation involves the addition of souls of iron or aluminum. Inorganic salt helps neutralizer the charge on the particles that caused the ability in raw water. It also contributes to hydrolyze the particles that form insoluble precipitates. 

Flocculation begins when neutralize particles start to collide with one another and fuse to form larger particles. It is a natural Water Treatment process, but sometimes, polymeric flocculant aid helps speed up the process.

Disposal Of Solid wastes

Manufacturers must always dispose of industrial wastewater as per government Water Treatment regulations and geographic location. The final stages of disposing include incineration, land application, reclamation, and landfill. 

Water Treatment By EPSCO

EPSCO is one of the leading companies in the air and water treatment industry. With over two decades of experience in the industry, the company now operates across three major continents with 18 specialized branches. The sole motive of the company is to protect the environment meet the ever-increasing energy demand of the world. The company offers a wide range of WaterTreatment Systems to treat industrial chillers, boilers cooling towers, and softness. Armed with a team of trained and certified professionals, EPSCO offers services like

·       Reverse osmosis system

·       Ozone disinfection

·       Multimedia filter

·       Whole house water filtration system

Appropriate Water Treatment of industrial effluents help companies show their concern towards the environment. It also plays a significant role in the protection of the equipment and the reputation of the organization. The food processing industry is now implementing Chilled Water Treatment according to regulatory measures to control effluent discharge in nearby water bodies.

The power industry uses the latest technologies as mandated by the government to reduce its carbon footprint. Processes like pond dewatering, leachate, low-level waste run-off streams, and Chilled Water Chemical Treatment to lower waste discharge. They are collaborating with Water Treatment Companies like EPSCO to improve product life cycles and reduce environmental impact without compromising efficiency.
