Types of Wastewater Filtration Units

Used for Industrial Wastewater Applications

Wastewater filtration units

Many industrial companies produce wastewater as a part of their production process. For such companies, a wastewater treatment system can be helpful. With the help of a wastewater filtration unit, a company can ensure that it meets discharge regulations. They can also recycle water and prevent any harm to the environment. But what type of wastewater treatment unit should a company get?

There are different types of filtration units available for wastewater. Let's learn more about the differences.

What is a wastewater filtration or treatment system?

An industrial wastewater treatment system, powered by different mechanisms, treats water discharged by factories. This water is contaminated by the activities of the factory or the industry in general. This treatment process is performed before the wastewater is released into the environment. Such a treatment option results in clean water that can be reused.

A vast majority of industries produce wastewater. However, many of the companies are trying to take a step towards change. They are trying to opt for some form of water treatment to minimize pollution and wastage of water. Many of them want to follow protocols to clean water with the help of a wide range of water treatment systems that remove every particle of solid material and organic material from water.

What does a wastewater treatment system typically remove?

Industrial wastewater contains different types of contaminants. These include chemical compounds, organic material particles. Different treatment systems are engineered to handle suspended and dissolved solids of varying particle sizes. Particle pollutants use the following:

Pollutants may thus include pathogens, plant nutrients, synthetic chemicals, organic wastes, biological solids, inorganic chemicals, radioactive substances, etc. Industrial facilities can be the source of many of these pollutants. These can be removed with the help of wastewater treatment systems that involve primary treatment, secondary treatment, and tertiary treatment methods.

Types of Wastewater Filtration Unit

Water filtration is a water cleaning solution that removes dense particles and debris of different sizes from water. It can prevent bacterial growth. This often allows water to be reused by any industry. There are many different types of filtration units that use enhanced treatment technologies like self-cleaning filters and biological treatment processes for clarified water.

The different types of wastewater filtration units are as follows:

a) Particle Filtration System:

A particle filtration system helps separate solid wastes from water, for which it uses mechanical or physical methods. It is one of the first steps to be followed for treating contaminated water. This type of filtration of particles of 1 micron or above. There are three major types of particle filtration systems -

i) Bag Filtration System

This is a cost-effective method of filtering wastewater. They are used for small applications to minimize waste. These filters resemble a bag that's somewhat elongated. Solid particles get stuck to the walls of the bag when wastewater passes through its porous walls. Multi-bag filtration is used for a higher flow rate.

ii) Cartridge Filtration Unit

These filters are made of some pleated fabric or screen. These are modular units designed to trap particles and chemicals. These filters can further be subdivided into a) depth filters and b) surface filters. Together, they have the capability to handle thick media and surface water. They are widely used in the industry.

iii) Self-Cleaning Water Treatment Unit

Another type of wastewater treatment is the self-cleaning water treatment system. It is pricier than the other systems of this category, but it's also one of the most useful. They are highly demanded because of their self-cleaning feature and can be customized to handle particles of various sizes.

b) Membrane Filtration Systems

Membrane filtration systems are an excellent option when particle filtration is not enough, especially for water recycling. The steps needed for this process may vary depending on what the final filtered water will be used for. Recent improvements in these systems have lowered their prices significantly.

i) Reverse Osmosis Filtration System

This type of filtration system is ideal when the solute and the solvent need to be separated. This means it can help remove tiny particles from water - when the water passes through membranes. It is highly effective in removing tiny organic particles, as well, thus filtering out all contaminants completely.

ii) Ultrafiltration

Ultrafiltration is usually a precursor to RO filtration. Low pressure is used to perform it as the water passes through small pores of the filter. The pores can be 5-100 nanometers. It is excellent at silt and granular sand filtration, organic material, pathogens, etc. It may involve the use of chemical processes.

iii) Microfiltration

Another method that is used right before an RO process is microfiltration. This is similar to ultrafiltration, though the membrane through which it is passed has larger pores. It effectively removes certain large bacteria and suspended solids from water and is a good step to take in the treatment of wastewater.

Final Words

Industrial wastewater can be much more harmful and contaminated than domestic wastewater, which is why it is essential to treat it.

Ozone for Food Production

Ozone has been proven as a safe, cost-effective, and efficient method for killing micro-organisms and bacteria. Ozonated water is perfect for ‘Post Harvest Washing’ as it sterilizes the food product and eliminates the risk of microbiological contamination. Delicate fruits in particular benefit from Ozone sterilization because it does not require the vigorous washing associated with other methods.
