Solar-based & low energy water treatment

Solar-based and low energy water treatment systems

There are a wide range of water and wastewater treatment systems empowered by solar based electricity and are designed to purify low quality, brackish or saline water, and softening hard water.

The systems have a wide range of applications, in both the residential and commercial sector. By fitting the water treatment system with advanced filtration systems, pure drinking water can be generated. The scalability of the size of systems means that this could be used in any building from small residential houses to large hotels.

In industrial processes, large quantities of waste water is generated and must legally be treated. Using solar based water treatment systems allows not only the treatment of the water but also the recycling and reuse of the water, which can result in significant cost and carbon savings.

Since all the system can run directly off solar panels and do not require a grid system to be in place, there are significant applications for remote areas which operate as a microgrid. This can generate clean drinking water or treatment of waste water which would otherwise cause a health hazard.


      • Improving the quality of mains water
      • Zero electricity consumption
      • Low maintenance
      • Promoting sustainability
      • Short payback period compared to many other water treatment systems
      • Suitable for remote area deployment

Why should you invest in Solar-based and/or low energy water treatment systems?

These systems are perfect solutions for remote areas where water and/or energy supply is not reliable.

Frequently Asked Questions

What is Solar water disinfection?

Solar water disinfection is a process of disinfecting water by using the heat from the sun. It is used in developing countries to treat contaminated water.

Solar water disinfection involves exposing the contaminated water to sunlight for a period of time to allow for the natural UV rays to kill any microorganisms that might be present in it.

The process has been found to be effective in reducing microbial populations and improving the quality of drinking water, but it has not been as successful at removing chemical contaminants from groundwater supplies.

How does Solar water disinfection work?

Solar water disinfection is an alternative method of water purification that uses the sun’s rays to kill harmful bacteria and make drinking water safe.

This system works by exposing a filled container of water to direct sunlight for long periods of time. The solar radiation will then heat up the water, which in turn kills harmful bacteria. This process is also known as solar pasteurization or SODIS.

The process is relatively simple and does not require any expensive equipment or chemicals like chlorine or iodine, which are often used in other methods of purification. It can be done by just using plastic bottles and placing them on the roof or near a window with direct exposure to the sun’s rays.

Is solar water disinfection safe?

Solar water disinfection is a safe and effective way to solve the problem of contaminated water.

Solar water disinfection is a safe and effective way to solve the problem of contaminated water. It is an affordable, sustainable and environmentally-friendly solution that can be used in any region where there is plenty of sunlight.

The process involves heating the water in a solar collector until it reaches about 70°C, then pumping it into a storage tank for use later. The heat from the sun destroys bacteria, viruses, and protozoa that could make people sick or kill them.

What are the main components of a solar water system?

A solar water system is a device that collects and stores solar energy to provide hot water. It typically consists of a solar thermal collector, a storage tank, and a heat exchanger.

Some of the components of solar water systems are:

– Solar thermal collectors: These are made up of flat panels that absorb the sun’s heat and transfer it to the storage tank. They can be installed on roofs or ground-mounted.

– Storage tanks: These contain the heated water until it is needed. They are insulated to prevent heat loss and have an automatic shutoff valve in case they overflow due to high demand for hot water.

– Heat exchangers: These turn the liquid from the storage tank into gas or vapor so that it can be used in your home’s hot water heater or radiant floor heating system.

– Hot water heater: This heats up cold tap water so you can enjoy warm showers or baths at home.
