So there is no hassle of boiling water and no risk of chemical mixing.

Its 100 GPD purification capacity ensures 100% safe, pure & mineralized water at home through 6 advanced purification stages (MF+CF+UF+RO+TDS Modulator+ Post Carbon Filter). Additional pre-treatments like Iron Remover, Water Softener, etc. (up to 3 extra stages) may be required based on your water quality test report which ULTIMA Water Advisor will recommend you after testing your supply water.

Generally, CLEANTECH ENGINEERING Water Purifier is capable of purifying any kind of water. If the input water has impurities normally not present in drinking water (High Iron/Turbidity/Microbial Contamination Etc.) or water is from unknown resource (river/lake/pond/bore well etc.) then additional pre-treatments like Iron Remover, Water Softener, etc. (up to 3 extra stages) may be required based on your water quality test report which CLEANTECH ENGINEERING Water Advisor will recommend you after testing your supply water. Basically our Mandatory 6 stages RO purification system is suitable for Bangladesh Municipal water (Up to TDS-150).

Although Bangladesh WASA has strong Water Management system of removing the fine and coarse particulate impurities and dirt that lowers the TDS level at 80PPM to 100 PPM, but due to the mismanagement of water supply pipeline and water tank, the TDS level becomes more than 300 PPM. This is why CLEANTECH ENGINEERING firstly tests your water quality and then recommends the proper treatments.

CLEANTECH ENGINEERING’s domestic RO models have minimum 100GPD (100Gallon per day) which means 15.78 liters per hour. Although it may seem that you do not need such a big capacity for home use, it actually increases the longevity of your purchased device significantly by lowering the pressure on the device.

However, CLEANTECH ENGINEERING has a Self-Priming booster pump inside which makes CLEANTECH ENGINEERING devices independent from input water pressure so that it can purify continuously even there is a very low supply water pressure.

Generally, all domestic CLEANTECH ENGINEERING RO Water Purifier model is specially designed for Bangladeshi medium to big families and powered by 100GGPD(16ltr/Hour) purifying capacity and 10Ltr storage tank. You can choose any CLEANTECH ENGINEERING domestic RO device without any confusion.
Our Mandatory 6 Stages RO purification system is suitable for Bangladesh Municipal water (Up to TDS-150).

The water of the 1^st Purification cycle should be thrown out. CLEANTECH ENGINEERING’s installer man will ensure this by taking all the water of the 1^st purification cycle. So you can drink the water immediately after our installer man has finished his installation process.

We recommend you to discard the water, refill and then consume if it is not used for more than 7 days.

CLEANTECH ENGINEERING RO device comes with 100% food-grade maintained Plastic shielded and 50 PSI Air Pressure Reserve Tank so that there is no chance of purified water to have open-air contact and it saves the water from re-contamination. CLEANTECH ENGINEERING never recommends using the Open Box Reserve Tank System available in the market.
