Frequently Asked Questions

Our water sources are increasingly getting polluted. As a result the water we get is full of impurities and not fit for drinking.

  • River water, which is our primary source of water, gets contaminated due to various reasons such as direct disposal of sewage by municipalities, excessive discharge of industrial pollutants, use for daily chores like washing, bathing, livestock bathing, garbage disposal, etc.

  • Water sourced from groundwater too has deteriorated due to the excessive use of pesticides & insecticides in agriculture, which seep into the groundwater as well as get washed away into the rivers. Decreasing levels of groundwater also attracts natural contaminants present in the earth such as Arsenic, Fluoride, Lead, Heavy Metals, which make the water hard.

  • Our municipalities are not well equipped to completely purify the water we drink. They are unable to remove harmful dissolved impurities as they use outdated methods of purification such as chlorination and filtration. The pipes in which the water is supplied are rusty which makes the municipal water polluted and the overhead tanks in which water is stored are breeding grounds for bacteria and viruses as they are seldom cleaned.

  • Impurities found in drinking water can be broadly classified into:

  • Suspended impurities such as mud, dust, sand, bacteria, viruses, cysts, etc

  • Dissolved impurities that become soluble in water such as-

  • Pesticides (commonly found in borewell water)

  • Arsenic & Fluoride (found in groundwell water)

  • Heavy Metals salts like mercury, lead, copper, cadmium (from industrial wastes)

  • Dissolved Impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. are harmful to our health. They may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer. They also spoil the taste of water. When these dissolved impurities are removed, the water becomes healthy as well as tasty.
    The most commonly used methods of purification are Chlorination, Boiling, Ultra filtration (UF), Ultra Violet (UV) Disinfection and Reverse Osmosis (RO) Purification.
    Boiling kills bacteria and viruses but does not remove harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Just as we cannot remove dissolved salts from water by boiling, similarly we cannot remove dissolved impurities from water by boiling.

    Presence of such impurities in water may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer.
    UV purification has been popular since last few years. It does kill bacteria and viruses but does not remove dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Also ‘khaara’ water does not become sweet.
    RO purification is the latest technology to come up in the market and has gained popularity. Apart from killing bacteria and viruses, it effectively removes dissolved impurities as well. However, while doing so, it removes natural minerals also from the water which are essential to our health.

    Thus it renders the water totally mineral-less. Such water can prove to be dangerous in the long run as it can lead to mineral deficiency in the body.
    The need of the hour is to have a purification technology which effectively removes harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride, etc apart from other impurities like bacteria and viruses. At the same time, the purifier should retain essential natural minerals in drinking water. It should also work efficiently over a long period of time.

    Thankfully, such a purification technology is available today!
    RUMA's Mineral RO water purifiers are based on the ground-breaking computer controlled patented RUMA's Mineral ROTM Technology. It combines the best of both RO and UV purification processes, while eliminating the limitations of a single technology to give 100% Safe, Healthy and Tasty water over a long period of time.

    RO : Removes even Dissolved Impurities like Pesticides, Rust, Heavy Metals, Arsenic, Fluoride, etc, besides removing other impurities such as bacteria and viruses.

    UF : Removes bacteria and cysts.

    UV : With double purification, it ensures complete removal of remaining bacteria and viruses.

    TDS Controller: Maintains essential natural minerals in purified water by adjustment of Total Dissolved Solids (TDS) control valve.

    RUMA’s Mineral ROTM Technology has the following distinct Advantages over conventional RO water purifiers:

  • Double purification: Ensures complete removal of impurities.

  • Retention of essential natural minerals: Conventional RO purifiers while removing dissolved impurities also remove essential natural minerals from the water. Whereas in RUMA water purifiers, while dissolved impurities are removed, essential natural minerals are retained.

  • International certifications: RUMA purifiers have to their credit world’s top quality certifications such as WQA and NSF of USA.

  • Unlike conventional water purification processes based on a single technology, RUMA water purifiers work through double purification by RO and UV/UF. It has the following distinct advantages:

  • Double purification leaves less scope for impurities to pass through.

  • Ensures bacteria and viruses are totally killed.

  • Although RO purification process removes even dissolved impurities, back-up purification by UV and UF processes makes the water 100% Safe all the time.

  • Natural minerals are essential for our health. In conventional RO water purifiers, these natural minerals get removed along with dissolved impurities. This makes the water mineral-less. Such water may be harmful to our health and can cause mineral deficiency in the body.

    RUMA's Mineral RO water purifiers are equipped with a TDS controller, which retains essential natural minerals in the purified water.
    Computer Controlled process has the following advantages:

  • It controls important functions and ensures only 100% Safe water is available all the time.

  • Computer controlled Filter Change Alarm, forewarns the user when the filter needs to be replaced.

  • Makes the purifier fully automatic and saves one from the headache of manually switching the purifier on and off.

  • In normal RO purification process to get 1 litre of purified water, 4 litres of water is wasted. RUMA’s 0% Water Wastage technology enhances the performance of RO water purifiers and reduces the rejection to just 1 litre of water for every 1 litre of purified water.

    Further, a separate tank is provided for the rejected water, which can later be utilized for household purposes.
    The rejected water can be used for household purposes like washing utensils, watering plants, mopping, cleaning, etc.

    Quality Certificates are issued by a third party, comprising of International water experts, after they perform stringent tests in accordance with international standards.

    Not only the quality of water but also that of the water purifier is tested for its sturdiness and effectiveness over a long period of time. The certificate denotes that performance of the water purifier has been rigorously tested by a neutral agency and it has complied with all the testing standards.

    In the water industry, such certifications are provided by renowned laboratories of the world such as WQA and NSF in USA, who have set the world standards for water purification.

    RUMA has to its credit international certifications from both WQA and NSF in USA apart from numerous other accreditations. This provides assurance that the water you get from RUMA purifiers is 100% safe and complies with the highest standards of water purification treatment.
    Continuous availability of pure water to one’s family is essential. Keeping this in mind, it is important to have a good after-sales service back-up, so that in case any problem arises, it can be addressed in the least possible time.

    CRUMA has over the years won many awards and accolades such as Asia’s most Promising Brand, India’s most Trusted Water Purifier, Best Domestic Water Purifier Award, etc.

    This is not only a reflection of RUMA’s commitment to quality but also a testimony to its ground-breaking technology.
