TES are extremely proud of our highly successful track record in water treatment and we remain committed to playing a critical role in the delivery of this essential resource.
RESEARCH & DEVELOPMENT
At TES, we are committed to research and development, with particular focus on water treatment technologies. We take pride in finding the most cost-effective, high performance and eco-friendly solution for our Clients. Starting from evaluation of the best technical solution to installation, we can supply complete processes with excellent performance, some of which include:
- Raw water settlement & screening or ozone treatment
- Coagulation & flocculation using chemicals [poly, soda, alum etc] and settlement tank systems
- Filtration – rapid gravity media or pressure filters
- Final treatment by uv, chlorine or fluorine
- Pumping from ground source, boosting and distribution
TES understand the importance of integrating with our Clients, as we deem this critical to successful project delivery. After thorough consultation and scrupulous assessment of Client requirements, TES engineer innovative, tailor-made solutions. Our customer focused philosophy reflects our commitment to continual innovation and successful partnering.
Our dedicated team of engineers have immense experience in implementing a number of water treatment processes, including:
FLOCCULATION
A method which clarifies the water to ensure it is clear and colourless. Clarification causes a precipitate to form in the water which can be removed using simple physical methods. Initially the precipitate forms as very small particles but as the water is gently stirred, these particles stick together to form larger particles.
SEDIMENTATION
Water exiting the flocculation basin may enter the sedimentation basin. It is a large tank with slow flow, allowing floc to settle at the bottom. As particles settle at the bottom of the basin, a layer of sludge is formed on the floor of the tank. This layer of sludge is removed and treated. In many cases the tank can be equipped with mechanical cleaning devices.
FILTRATION
After separating the floc, the water is filtered as the final step to remove remaining suspended particles and unsettled floc. TES have a vast knowledge of a variety of filter methods to include rapid sand filters, membrane filters and pressure filters with various types of media.
Ultrafiltration membranes use polymer membranes with chemically formed microscopic pores that can be used to filter out dissolved substances avoiding the use of coagulants. The type of membrane media determines how much pressure is needed to drive the water through and what size of microorganisms can be filtered out.
DISINFECTION OF WATER
Is accomplished both by filtering out harmful microbes and by adding disinfectant chemicals in the last step in purifying drinking water.
