Water Treatment
Water treatment is any process that makes water more acceptable for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use.
IRON AND MANGANESE REMOVAL
Iron and manganese are common elements found in the Earth’s crust. While essential for human health in trace amounts, they can cause significant problems when present in high concentrations in water supplies, particularly in deep well water. These issues can affect both the aesthetic quality and usability of water, making it important to understand and address them effectively.
Iron and Manganese can be removed catalytically using an iron removal filter. The filter media could be granular media or a resin media.
Our brand PYROLOX is a granular water filter media used for the removal of iron, manganese and hydrogen sulfide.

WATER SOFTENING
Water hardness, caused by elevated levels of calcium and magnesium, poses significant challenges for homeowners and businesses alike. It leads to scale buildup in pipes and appliances, diminishing their efficiency and lifespan, while also causing unsightly stains on fixtures and laundry. Additionally, hard water reduces the effectiveness of soaps and detergents, making cleaning tasks more difficult. Investing in water softening solutions can greatly improve water quality, protect your plumbing, and enhance the overall efficiency of your household or commercial operations.
With the use of WATER SOFTENER, it softens the water by removing minerals such as calcium and magnesium and replacing them with a softer mineral sodium or potassium. Soft water can also make your hair and skin look and feel healthier because hard water can dry them out.
Advantages/Benefits
-
Extended Appliance Lifespan:
Water softeners prevent scale buildup in appliances like water heaters, dishwashers, and washing machines, prolonging their lifespan and reducing the need for costly repairs or replacements. -
Improved Cleaning Efficiency:
Softened water lathers more easily with soap and detergent, resulting in better cleaning performance and reduced usage of cleaning products. This not only saves money but also leads to cleaner dishes, clothes, and surfaces.
-
Reduced Maintenance Costs:
By preventing scale buildup in pipes, fixtures, and plumbing systems, water softeners minimize the need for maintenance and repairs, saving both time and money in the long run. -
Enhanced Comfort:
Softened water feels smoother on the skin and leaves hair softer and more manageable after washing. This improves the overall bathing experience and reduces the risk of skin irritation caused by hard water minerals.

TANNIN REMOVAL
Issues with tannins in water can lead to various problems, including discoloration, unpleasant taste, and foul odor. Tannins are organic compounds commonly found in surface water sources, such as lakes and rivers, and can also leach into groundwater from decaying vegetation. These compounds can give water a yellow to brown tint and impart a bitter or astringent taste, affecting its usability and aesthetic appeal. Addressing tannin contamination is crucial for improving water quality and ensuring it meets acceptable standards for consumption and usage.
Several water treatment technologies effectively address tannin contamination. Activated carbon filtration, utilizing porous carbon media, efficiently adsorbs tannin molecules, resulting in clearer and better-tasting water. Ion exchange systems are also effective, with resin beads exchanging tannin ions for chloride ions, reducing tannin concentrations. Oxidation methods, such as chlorination or potassium permanganate treatment followed by filtration, break down tannins, effectively removing them from the water. These treatment options offer reliable solutions for eliminating tannin-related issues and ensuring the delivery of clean, high-quality water for various domestic and industrial purposes.
rADON REMOVAL
Radon is a naturally occurring gas that you can’t see, taste, or smell. It is produced by the breakdown of radioactive elements normally present in soil, rock, and water. This radioactive element may cause cancer in the long run. Some radon stays in the water; drinking water containing radon also presents a risk of developing internal organ cancers, primarily stomach cancer.

REVERSE OSMOSIS - BRACKISH WATER
Reverse osmosis (RO) is a widely utilized technology for treating brackish water, which typically has moderate levels of salinity ranging from 1,000 to 3,000 ppm of Total Dissolved Solids (TDS). Brackish water sources, such as wells, rivers, or reservoirs, often require advanced treatment to produce high-quality water suitable for potable or industrial use. The RO process efficiently removes dissolved salts, minerals, and impurities by forcing water through semi-permeable membranes under high pressure.
The RO system begins with raw water intake, where brackish water is pumped from its source. Before entering the RO unit, the water undergoes pretreatment to protect the membranes and enhance system performance. Pretreatment includes coarse screening to remove debris, chemical dosing with coagulants and anti-scalants, and multi-media and cartridge filtration to eliminate particulates and reduce turbidity.

REVERSE OSMOSIS - DESALINATION
Seawater typically has a salinity level of 3000-40000 ppm total dissolved solids (TDS). Seawater reverse osmosis (SWRO) treatment begins with the intake of seawater through specially designed structures that minimize environmental disturbance while preventing the entry of large debris. The raw seawater undergoes pretreatment to remove suspended solids and impurities through filtration and chemical conditioning, such as the addition of coagulants and anti scalants. This ensures the water quality is suitable for the sensitive reverse osmosis membranes. In some cases, advanced filtration methods like ultrafiltration may be employed for enhanced pretreatment.
The pretreated water is then pressurized using high-pressure pumps to overcome the natural osmotic pressure of seawater, typically around 800–1,000 psi (55–70 bar). It passes through semi-permeable reverse osmosis membranes, which separate freshwater from dissolved salts and impurities. The process produces two streams: permeate, the desalinated water, and brine, a concentrated saline solution. To improve energy efficiency, modern SWRO systems utilize energy recovery devices to capture and reuse energy from the high-pressure brine stream, significantly reducing operational costs.
Benefits of SWRO Systems

uLTRAFILTRATION WATER TREATMENT
Ultrafiltration (UF) treatment is a membrane-based water purification process that removes suspended solids, colloids, bacteria, viruses, and other impurities from water. The process begins with the feed water being passed through pre-filters to remove larger particles and reduce the load on the UF membranes. The water is then pumped under moderate pressure into the UF system, where it flows across hollow fiber or flat sheet membranes with microscopic pores, typically ranging from 0.01 to 0.1 microns. These pores act as a physical barrier, allowing water and dissolved salts to pass through while retaining suspended particles and microorganisms.
The UF system operates in either a crossflow or dead-end filtration mode. In crossflow filtration, a portion of the water sweeps impurities away from the membrane surface, reducing fouling and extending membrane life. In dead-end filtration, all the water passes through the membrane, requiring periodic backwashing to remove accumulated contaminants. The permeate (filtered water) is collected for further treatment or use, while the concentrate (rejected impurities) is discharged or recycled depending on system design.
UF treatment offers several advantages, including consistent water quality, high removal efficiency for pathogens and turbidity, and minimal chemical usage. It is commonly used as a pretreatment step for reverse osmosis (RO) systems, protecting RO membranes from fouling and scaling. Additionally, UF systems are energy-efficient and compact, making them suitable for applications ranging from municipal drinking water production to industrial process water and wastewater treatment.
