Gditech Purified Water Machines

Gditech is a leading company in Kenya that specializes in producing high-quality water purifiers, water vending machines and equipment. Our purified water machines are state-of-the-art devices that use various techniques to purify water from different sources. They feature a powerful reverse osmosis system that ensures the water is free of contaminants and meets the highest standards of purity.

Our purified water machines can handle water from boreholes, dams, seas, rivers and other sources that have high levels of pollution. They are available in two models: one that can treat water with high TDS (total dissolved solids) and one that can treat water with low TDS. Depending on the water source and the desired quality, you can choose the model that suits your needs.

Our purified water machines are ideal for businesses that require pure water for their operations, such as water vending, hospitals, beverage production and more. They can remove all kinds of impurities from the water, such as sediment, taste, odour and bacteria.

They use a six-stage treatment process that does not involve any chemicals, making them safe and eco-friendly. They are also easy to operate, reliable and durable. The only maintenance they require is regular cleaning and cartridge replacement.

Features of Gditech purified water machines:

Pre-chlorination: This is a process of adding chlorine to the raw water to kill bacteria and other microorganisms, and to prevent algae growth in the subsequent stages.

Flocculation: This is a process of adding chemicals, such as alum, to the water to form flocs, which are clumps of particles that settle at the bottom of the tank, leaving the water clearer.

Sand filtration: This is a process of passing the water through a bed of sand, which traps and removes the remaining suspended solids, turbidity, and some microorganisms from the wate.

Carbon filtration: This is a process of passing the water through a bed of activated carbon, which adsorbs organic compounds, chlorine, taste, odor, and some pesticides from the water.

Birm filters: These are filters that use birm, which is a granular material that oxidizes and removes iron and manganese from the water.

PH adjustment: This is a process of adding chemicals, such as lime or soda ash, to the water to adjust its pH level, which affects the taste, corrosion, and scaling potential of the water.

Activated alumina: This is a process of passing the water through a bed of activated alumina, which removes fluoride, arsenic, and selenium from the water.

Other features:

No use of chemicals: This means that the water purifiers do not use any harmful chemicals, such as chlorine, to disinfect the water, which can have adverse effects on health and the environment.

Simple to operate: This means that the water purifiers are easy to use and do not require any special training or skills to operate them.

Consistent pure water: This means that the water purifiers produce water that is free of contaminants, such as bacteria, viruses, chemicals, metals, and salts, and that meets the quality standards for drinking water.

High stable water: This means that the water purifiers produce water that has a stable pH level, hardness, and mineral content, and that does not cause corrosion or scaling in pipes and appliances.

No other maintenance other than routine cleaning and cartridge replacement: This means that the water purifiers do not require any costly or complicated maintenance, except for regular cleaning and changing of the filters and cartridges, which can be done easily and quickly.

Capacities range from 250 ltrs/h—3000 ltrs/hr: This means that the water purifiers have different production capacities, depending on the size and model, and that they can produce from 250 liters to 3000 liters of purified water per hour.

The Gditech purified water machines are suitable for treating the following types of water:

Borehole water: This is a type of groundwater that is accessed by drilling a hole or a well into the earth’s surface, reaching the underground water-bearing layers called aquifers. Borehole water can be a reliable and convenient source of water, especially in areas where surface water is scarce or unreliable. However, borehole water can also have some drawbacks, such as containing high levels of fluoride, iron, salinity, hardness, and other contaminants that can affect the taste, quality, and safety of the water.

These contaminants can also cause health problems, such as dental fluorosis, iron deficiency, hypertension, kidney stones, and metal poisoning. To overcome these challenges, the Gditech purified water machines use reverse osmosis (RO) systems, which are advanced filtration processes that use a semi-permeable membrane to remove up to 99% of the dissolved solids, ions, bacteria, viruses, and organic compounds from the water. The RO systems produce clean and safe drinking water that meets the World Health Organization (WHO) standards.

Saline water (sea/ocean water): This is a type of water that has a high concentration of dissolved salts, mainly sodium chloride, which gives it a salty taste. Saline water is found in seas, oceans, salt lakes, and some underground sources. Saline water is not suitable for human consumption or irrigation, as it can cause dehydration, health problems, and soil degradation.

For example, drinking saline water can increase the blood pressure, damage the kidneys, and impair the brain function. Irrigating with saline water can reduce the crop yield, affect the soil fertility, and increase the soil salinity. To address these issues, the Gditech purified water machines use RO systems, which can desalinate saline water and make it fresh and potable. The RO systems can remove up to 99% of the salt and other impurities from the water, making it suitable for drinking and irrigation.

Dirty river water: This is a type of water that is collected from rivers or streams that may be polluted by human or animal activities, industrial waste, agricultural runoff, or natural disasters. Dirty river water can have a cloudy appearance, a foul smell, and a bad taste. Dirty river water can also contain harmful bacteria, viruses, parasites, chemicals, metals, and organic matter that can cause diseases and infections, such as cholera, typhoid, dysentery, hepatitis, and arsenicosis.

To prevent these risks, the Gditech purified water machines use RO systems, which can filter out these pollutants and purify dirty river water. The RO systems can remove up to 99% of the microorganisms, pesticides, herbicides, heavy metals, and other contaminants from the water, making it clear, odorless, and safe.

Operation of our purified water machines:

High-Quality Reverse Osmosis Water Purifiers

STEP 1: The first step in the operation of the Gditech purified water machines is to pump the raw water through a filter that contains sand media. This filter is also known as a sand filter or a multimedia filter. The purpose of this filter is to remove any suspended particles, such as dirt, sand, clay, and organic matter, that could clog the reverse osmosis (RO) membranes in the next step. The sand filter also reduces the turbidity and the silt density index (SDI) of the water, which are measures of the clarity and the fouling potential of the water, respectively ¹.
STEP 2: The second step is to add an anti-scalant to the water to prevent scaling of the RO membranes. Scaling is the formation of deposits of minerals, such as calcium carbonate, calcium sulfate, and silica, on the surface of the membranes, which can reduce the water flow and the quality of the product water. An anti-scalant is a chemical that inhibits the precipitation and crystallization of these minerals by altering their solubility and morphology.

The anti-scalant used in the Gditech purified water machines is GE Hypersperse MSI 310, which is a proprietary blend of phosphonates, polymers, and dispersants that can effectively control scaling in a wide range of water conditions. The anti-scalant is continuously supplied to the pipeline before the RO process takes place, using a metering pump and a chemical tank.

STEP 3: The third step is to adjust the pH of the water to retain the natural taste and stability of the water. The pH is a measure of the acidity or alkalinity of the water, which affects the taste, corrosion, and scaling potential of the water. The optimal pH range for drinking water is between 6.5 and 8.5, according to the World Health Organization (WHO) guidelines. To achieve this range, a chemical dosing pump with a chemical tank is used to add either an acid or a base to the water, depending on the initial pH of the water. For example, if the water is too acidic, a base such as sodium hydroxide or sodium carbonate can be added to increase the pH. If the water is too alkaline, an acid such as hydrochloric acid or sulfuric acid can be added to decrease the pH.
STEP 4: The fourth step is to send the “pre-treated” water through a reverse osmosis unit, which will lower the total dissolved solids (TDS) and condition the water. TDS is a measure of the amount of dissolved salts, minerals, metals, and organic compounds in the water, which affects the taste, quality, and safety of the water. The RO unit consists of a high-pressure pump, a pressure vessel, and a semipermeable membrane. The high-pressure pump applies a pressure greater than the osmotic pressure of the water, which forces the water molecules to pass through the membrane, leaving behind the dissolved solutes.

The RO unit can remove up to 99% of the TDS and other contaminants from the water, such as bacteria, viruses, pesticides, herbicides, and heavy metals. The water that passes through the membrane is called the permeate or the product water, which can be stored in a clean water tank (as determined by the client). The water that does not pass through the membrane is called the concentrate or the reject water, which contains the concentrated solutes and is discharged or recycled.

STEP 5: The fifth and final step is to sterilize the water before bottling or distribution. Sterilization is the process of killing or inactivating any remaining microorganisms in the water, such as bacteria, viruses, and parasites, that can cause diseases and infections. There are two methods of sterilization that can be used in the Gditech purified water machines: ultraviolet (UV) disinfection or chlorination. UV disinfection is a physical method that uses UV light to damage the DNA and RNA of the microorganisms, preventing them from reproducing and infecting.

Chlorination is a chemical method that uses chlorine or chlorine compounds to oxidize and destroy the cell walls and membranes of the microorganisms, rendering them harmless. The choice of sterilization method depends on the preference of the client and the end use of the water. For example, if the water is intended for bottling, UV disinfection may be preferred, as it does not alter the taste or odor of the water. If the water is intended for direct consumption, chlorination may be preferred, as it provides a residual disinfection that can prevent recontamination in the distribution system.
