Frequently Asked Questions

The ZPM amplifies the coagulation and flocculation reactions for the conversion and precipitation of dissolved components into small particles. The cavitation reactions provide the perfect mixing and turbulent environment necessary for coagulation.
APF is a multi-spectrum coagulant and flocculant that can remove pollutants from solution and floc-culate fine suspended solids, such as skin cells and bacteria, into large particles that are easily remo-ved by AFM® (Activated Filter Media).
There are several ways you can find out what is in you water. A water analysis can be sent to State Approved laboratory like BUET and ICDDR,B. They test for a variety of different contaminants, both aesthetic and health related.
You can directly contact through email or phone no for placing any kind of order then, we will contact you for details.
Yes, all in home water treatment equipment needs occasional attention but those are taken care by our technical team. In that case we apply a monthly charge and that can be settled by the negotiation between our company and you.
If your water is coming from a well and the water is rust colored, then the problem is probably iron. If the water color is black it could be either sulfur, which has a smell like rotten eggs or manganese. All of these can be treated with an activated filter media (AFM) which specially designed to remove those pollutants from your supply water.
Keep in mind that there are many problems with water supplied by local water municipalities, especially for Dhaka WASA. A bigger concern is water distribution system which is too poor.  If you are concerned about the quality of your tap water then you have to conduct a laboratory test from a state approved lab. If the lab report indicates that there are some contaminants present in your tap water then off course, you have to install a system to produce a safe drinking water.
AFM® is manufactured from a specific glass type and processed to obtain the optimum particle size and shape. It is then activated to increase the surface area by 300 times over crushed glass or sand. The high surface area is negatively charged (zeta potential) to adsorb organics and small particles. It also has permanent metal oxide catalysts creating a high redox potential to make AFM® self-sterilizing. AFM® is the only activated glass filter media available, and is more efficient and cost-effective than any other filtration media.

An ultraviolet (UV) system uses UV to inactivate certain bacteria, viruses and cysts that may be present in the water source that flows through the systems UV chamber. The effectiveness of UV depends upon the dose of disinfectant received by the organism, which is the combination of UV intensity times the contact time involved. It is advisable to always pre-treat the water entering the UV system.
