What is an industrial water treatment system? 

An industrial water treatment system treats water, so it is more appropriate for a given use, whether for consumption, manufacturing, or even disposal.

However, each system will vary depending on the facility’s needs and many of the technologies that make up these systems can be similar.

In general, some of the most-needed industrial water treatment systems typically include:

  • Raw water treatment systems
  • Boiler feed water treatment systems
  • Cooling tower water treatment systems
  • Wastewater treatment systems

The technologies selected and in what order they appear in each water treatment system will vary depending on the contaminants that need to be removed. But it is possible to narrow down what you might see in these four common industrial treatment systems.

The following is a breakdown of what might be included in a typical water treatment system:

Raw water treatment systems 

Raw water is any untreated water that occurs naturally in the environment, including sources such as rainwater, groundwater, wells, lakes, and rivers.

In industrial settings, raw water may be used for cooling, rinsing, product formulations, or even human consumption if it is properly purified. 

Raw water treatment systems are used for pre-treatment and optimization of source water, usually with an eye toward improving production efficiency and process performance for a particular application.

Examples include pre-treating cooling tower/boiler feed water, process/production water, and/or water for drinking.

Often, raw water treatment is focused on protecting downstream equipment from scaling, fouling, corrosion, and other forms of damage or premature wear due to contaminants present in the source water.

Raw water treatment systems typically remove suspended/colloidal solids, silica/colloidal silica, iron, bacteria and hardness. 

 

Boiler feed water treatment systems 

Boiler feed water treatment systems are used to protect boiler unit components and piping from damage due to certain contaminants present in the boiler and/or makeup feeds.

These contaminants may include dissolved solids, suspended solids, and organic material, such as iron, copper, silica, calcium, magnesium, aluminium, hardness, and dissolved gases.

Without proper treatment, boiler feed water can cause scaling, corrosion, and fouling of the boiler and downstream equipment, which can result in costly plant downtime, expensive maintenance fees, increased fuel consumption and boiler failure. 

An effective boiler feed water treatment system works by both removing harmful impurities prior to entering the boiler as well as controlling the acidity and conductivity of the water.

While treatment trains vary, a typical system will consist of primary treatment and possibly polishing depending on the boiler pressure, steam use, and chemistry of the boiler feed and makeup water.  

Cooling tower water treatment systems 

Cooling tower water treatment regimens are required to protect cooling tower components from damage due to contaminants present in process water, circulation water and or blowdown water. These contaminants may include chlorides, hardness, iron, biological materials, silica, sulphates, TDS and or TSS.

Untreated cooling tower feed water can cause scaling, corrosion, biological growth, and fouling of cooling tower equipment, which can result in costly plant downtime, reduced cooling tower performance, and excessive maintenance or equipment replacement costs over time.

An effective cooling tower water treatment system works by removing harmful impurities in line with the manufacturer recommendations for water quality requirements for the type of cooling tower used.We specialise in international water treatment, Legionella control, water management, and bespoke cooling solutions for all industries. We are a major provider for cooling tower refurbishment, cleaning, parts, thermal upgrades, newbuilds, water treatment and chemical supply. We provide full turnkey projects for industrial cooling.

Wastewater treatment systems 

A wastewater treatment system is used to convert spent streams into an effluent that can either be reused or safely discharged to the environment or municipal treatment facility. 

The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s equipment, process or products (especially if the wastewater is being reused).

It will also help the facility curb heavy fines and possible legal action if wastewater is being improperly discharged to either the environment or publicly owned treatment works.

The relative complexity of a wastewater treatment system will depend heavily upon the compliance regulations impacting your plant and the composition of your waste stream. 

While the contaminants present in a waste stream can vary greatly from one process to the next, wastewater treatment systems commonly treat for biochemical oxygen demand (BOD), nitrates, phosphates, pathogens, metals, TSS, TDS and synthetic chemicals.
