IMPORTANCE OF WATER TREATMENT INDUSTRIES

Water treatment plants are facilities designed to purify water to make it safe for human consumption or other purposes. Water treatment can involve various physical, chemical, and biological processes, depending on the quality of the raw water and the specific goals of the treatment.

Some common steps involved in water treatment include:

Coagulation and flocculation

These processes involve adding chemicals to the water to help impurities clump together, making them easier to remove.

Sedimentation

The water is allowed to sit in a large tank, allowing heavier particles to settle to the bottom.

Filtration

The water is passed through several filters to remove the remaining impurities.

Disinfection

The water is treated with chemicals or UV light to kill any remaining bacteria or viruses.

pH adjustment

The pH of the water may be adjusted to ensure that it is safe to drink and will not corrode pipes or other equipment.

Water treatment plants are essential to modern infrastructure, as they help ensure people have access to safe, clean drinking water. Water treatment plants are also crucial for protecting the environment, as they help to prevent water pollution and the spread of waterborne diseases.

USES OF AIR COMPRESSORS IN WATER TREATMENT

Air compressors are commonly used in the water treatment industry to provide a source of pressurised air for various applications. Some common uses of air compressors in water treatment include:

Aeration

Air compressors help provide oxygen to water treatment plants to support the growth of microorganisms that are used to break down organic matter.

Sewage treatment

Air compressors provide the pressurised air needed for sludge dewatering equipment, which removes water from sludge to make it easier to handle and dispose of.

Fluidisation

Air compressors provide pressurised air for fluidisation systems. They are used for mixing and blending chemicals in water treatment processes.

Chemical injection

Air compressors can provide the pressurised air needed for injecting chemicals into water treatment processes.

Pneumatic control

Air compressors can power pneumatic control systems in water treatment plants, which use pressurised air to activate valves, pumps, and other equipment.

Membrane separation

Air compressors can be used to supply air to membrane separation equipment, which helps to remove impurities from the water through a process of pressurised filtration.

When selecting an air compressor for water treatment, it's essential to consider factors such as the required flow rate, pressure, and power source. ELGi wide range of technologically advanced air compressors offer suitable compressed air solutions for water treatment plants that meet the industry’s relevant regulatory standards.

In general, air compressors used in the water treatment industry should be reliable, efficient, and able to operate in demanding environments. It is essential to carefully consider the application's specific needs and choose an air compressor that is well-suited to the task.

AIR COMPRESSORS FOR THE WATER TREATMENT INDUSTRY

Wastewater treatment commonly uses the following types of air compressors to run their operations successfully:

100% Oil-Free technology

There may be a requirement for 100% oil-free compressed air in the water treatment plant. ELGi's oil-free air compressors offer suitable solutions for such requirements. Oil-free air compressors offer contaminant-free compressed air and ensure the process is free of traces of oil. Water treatment plants are required to provide clean water for utility work in factories or other applications.

Reciprocating air compressors

This positive displacement technology has a crankshaft driving the piston inside the cylinder, resulting in the compression process. A single-stage or multi-stage piston air compressor may be employed depending on the pressure requirement. When higher pressures are required, it may be a good idea to deploy a multi-stage or two-stage reciprocating air compressor to achieve the desired pressure in a step-wise method. This ensures a reduction in heat generated during the compression process, thereby making the process energy-efficient and safe.

Screw Air Compressors or Rotary Screw Air Compressors

Two identical, helical screw rotors are deployed for the compression process. The rotors are enclosed inside a sealed housing, and the setup is commonly referred to as an airend. In the case of lubricated screw air compressors, the lubricating oil forms a thin film between the two rotors to prevent them from heating up. In contrast, in the case of oil-free screw compressors, the lubricating material is PTFE or other proprietary coatings, which creates a lubricating film when the rotors heat up during the rotation process. When air passes through the rotors, it is compressed as it exits the airend. The compressed air is then passed through pipelines into a storage system, commonly referred to as an air receiver tank, where it is stored.
